Revisions to Maintenance and Preventive Maintenance Rule
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This rule amends the maintenance rules to allow properly
trained pilots of aircraft type certificated for 9 or fewer passenger
seats and operated under 14 CFR Part 135 to perform certain maintenance
tasks on their aircraft. This rule also adds certain tasks to those
items considered to be preventive maintenance. The changes are needed
because a large number of exemption requests has demonstrated a need
for pilots conducting certain types of operations to be able to respond
more rapidly to emergency medical missions and to reconfigure cabins to
accommodate changing needs to transport varying combinations of
passenger and/or cargo in situations when a certificated mechanic is
not available to perform the required maintenance task. This rule will
improve emergency response and flight turnaround times for these
operations, and will relieve the public and agency burdens of filing
and processing exemptions.
EFFECTIVE DATE: May 31, 1996.

SUPPLEMENTARY INFORMATION:
Background
Statement of the Problem
Many small air carriers operating under 14 CFR part 135 (part 135)
perform missions in locations where or during times when a certificated
mechanic may not be available to perform certain maintenance tasks that
need immediate attention. These air carriers provide emergency
ambulance service; transport internal organs for emergency medical
treatment; transport packages, parts, and electronic equipment whose
delivery is of a time-critical nature; and provide normal passenger-
carrying service, occasionally with freight as a secondary load.
Because the demand for these services varies and, especially in the
case of medical emergency calls, arises at all times of the day, it is
impossible for air carriers to anticipate airplane configuration
requirements.
Performing cabin conversions to aircraft operating under part 135
is considered either maintenance (if extensive) or preventive
maintenance (if simple), and must currently be performed by a
certificated mechanic as required by Sec. 43.3. Similarly, the removal
and replacement of medical oxygen bottles is considered maintenance and
must be performed by a certificated mechanic.
For many carriers, locating a mechanic each time a request for
service occurs creates lengthy delays that are costly and could be
potentially life threatening to injured or ill passengers. Similarly,
providing a maintenance crew on ``24-hour call'' is cost prohibitive
for many carriers.
In addition to imposing these burdens, the current regulations also
prohibit general aviation pilots from removing and replacing easily
removable communication and navigation devices, and from updating
easily replaceable data bases. Certain aviation communication and
navigation systems are now designed for easy removal and data base
update. Many privately-owned aircraft owners and operators prefer to
remove this self-contained equipment (a job that normally requires only
an allen wrench and no disassembly of the unit) to prevent theft. They
also would like to be able to insert flight plans or update the Air
Traffic Control (ATC) software data base. Current regulations require
that a mechanic perform these tasks.
History
The FAA has addressed over 250 petitions for exemption from the
sections of part 43 governing these ``maintenance'' items. A majority
of these petitions were from nonhelicopter, air taxi operators who
learned from local FAA inspectors that their pilots are not authorized
to reconfigure their cabins or exchange medical oxygen bottles. The
petitions for exemption highlight several common issues: (1) Many small
part 135 air carriers operate in areas where they undergo a hardship
due to their regions' lack of certificated mechanics; (2) Many others
operate during times when certificated mechanics are not normally on
duty (these missions are usually time-critical); and (3) Many of these
operators are unable to operate their aircraft in only one
configuration. Passenger-to-cargo or passenger-to-stretcher conversion
ensures the most efficient utilization of cabin space on each flight.
In most instances, seats stretchers, base assemblies, and other items
used in the conversion are approved for aircraft installation, and the
procedures for installation and removal are designed to be accomplished
safely by a trained person.
Historically, the FAA has granted exemptions to permit pilots of
aircraft operated under part 135 to perform seat removal and
replacement tasks only if the aircraft were operated in remote areas
such as the Alaskan bush or sparsely populated areas of the
Northwestern United States. Certificated mechanics servicing these
areas are scarce. Many of the operations include such essential
services as flying food, mail, needed goods, and people into and out of
areas that may not be accessible by other modes of transportation.
More recently, however, exemptions have been granted to part 135
air carriers to permit their properly trained pilots to reconfigure
cabin seats when flying missions of an emergency nature during times--
at night and on weekends--when certificated mechanics are not normally
available, and when a time delay incurred by locating a mechanic could
cause undue burden or create a life-threatening situation.
The FAA has determined that if a properly trained pilot can change
seat configurations in a remote area where a certificated mechanic is
not available (and which might be performed under adverse conditions),
he or she would be capable of and should be allowed to perform the same
conversions under better conditions such as those present at the
operator's maintenance base.
Passenger-to-cargo and passenger-to-stretcher conversions have been
performed safely by pilots who have been trained to do so and who are
employed by air carriers holding exemptions allowing their pilots to
perform the tasks. No reported incidents or accidents have been
attributed to properly trained pilots changing aircraft cabin
configurations. If an air taxi operator develops an appropriate program
for performing seat conversions and appropriately instructs and trains
its pilots according to the program, safety levels equivalent to those
achieved by certificated mechanics will be maintained.
Also, on January 10, 1994, the FAA published a Request for Comments
(59 FR 1326; docket No. 27581) to solicit from the public a list of
those regulations that are believed to be unwarranted or inappropriate.
The
[[Page 19499]]
agency received eight comments that addressed the maintenance and
preventive maintenance regulations of part 43. The commenters noted
that current regulations do not allow a pilot of a part 135 operator to
remove and reinstall aircraft cabin seats and stretchers. The comments
feel that the current regulations are unnecessary and are financially
and physically burdensome. They point out that the FAA has issued a
number of exemptions to relieve the burden, and that the exemption
process itself is burdensome and time consuming.
The FAA has determined that the concern shown for this issue is
significant, and that this rulemaking action is consistent with the
agency's responsibility to review the continuing need for its
regulations and to eliminate regulations that impose unnecessary
burdens.
Related Rulemaking
The Aviation Rulemaking Advisory Committee (ARAC), which is a
committee composed of aviation community and FAA personnel, has been
tasked with reviewing part 43 and Appendix A to determine what
revisions, if any, should be made. The FAA has not yet received any
recommendations.
The Current Rule
Part 43 requires air carriers to use certificated mechanics for
their aircrafts' maintenance and preventive maintenance needs. This
requirement reflects an FAA policy that passengers of all aircraft be
given a high degree of safety protection through the proper
installation of cabin seats and appointments. As outlined in Appendix
A, paragraph (c), of this part, removal and replacement of aircraft
seats is considered preventive maintenance.
Several years ago, the FAA recognized the need for pilots operating
helicopters under part 135 to be able to perform certain preventive
maintenance tasks when operating in remote areas. Accordingly, the
agency amended part 43, effective January 6, 1987 (51 FR 40702, Nov. 7,
1986), by adding a new Sec. 43.3(h), which authorizes part 135
certificate holders to allow their pilots, when operating rotorcraft,
to perform specific preventive maintenance tasks, under the following
conditions:
(1) The items of preventive maintenance must be a result of a known
or suspected mechanical difficulty or malfunction that occurred en
route to or in a remote area.
(2) The pilot must have satisfactorily completed an approved
training program and is authorized, in writing, by the certificate
holder for each item of preventive maintenance that the pilot is
authorized to perform.
(3) There must be no certificated mechanic available to perform
preventive maintenance.
(4) The certificate holder must have procedures to evaluate the
accomplishment of a preventive maintenance item that requires a
decision concerning the airworthiness of the rotorcraft.
(5) The items of preventive maintenance authorized by this section
must be those listed in paragraph (c) of Appendix A of part 43.
Discussion of Comments
A Notice of Proposed Rulemaking (NPRM) entitled ``Revisions to
Maintenance and Preventive Maintenance'' was published on July 18, 1995
(60 FR 36926), which solicited public comment. Forty comments were
received. Thirty-one commenters agree with the proposal as published.
Five commenters believe that airplanes with 10 to 19 passenger
seats should be included in the rulemaking, and one commenter believes
that rotorcraft with 10 or more seats should be similarly included. The
FAA disagrees. This rulemaking was precipitated by the volume of
exemption requests that were filed by operators who needed a shorter
turn-around time to respond to emergency medical missions and other
time sensitive operations, or who operated in areas where a
certificated mechanic was not available. Almost all of the exemption
requests were filed by operators whose airplanes are configured with
nine or fewer passenger seats. As stated in the NPRM, the FAA continues
to find that operators of aircraft type certificated for 10 or more
passenger seats are required to have a maintenance organization in
place to support their part 135 operations, and their aircraft tend to
be more complex in design and construction. The FAA will continue to
address operations using aircraft configured with 10 or more passenger
seats on a case by case basis. There will be no change to the proposed
rule as a result of these comments.
One commenter suggests that the regulatory language in Sec. 43.3(h)
be amended to include fixed wing aircraft with nine or fewer passenger
seats. The FAA disagrees. This rulemaking addresses specific tasks
associated with specific operations, and the suggestions of the
commenter are outside the scope of this action. There will be no change
to the proposed rule as a result of these comments.
One commenter proposes that the word ``aircraft'' be changed to
read ``airplane.'' The FAA disagrees. The rule is intended to include
rotorcraft so helicopter pilots can also perform the tasks prescribed
that allow for a shorter turn around in emergency situations. Without
the term ``aircraft,'' helicopter pilots transporting patients, for
instance, would not be allowed to reconfigure their cabins without an
exemption. The commenter also proposes that the word ``fewer'' be
replaced by the old term ``less'' in the context ``nine or fewer.'' The
FAA recognizes that people are familiar with the hold terminology, but
the agency is moving in a direction to correct grammatical errors
whenever rules are revised. The new term, ``nine or fewer'' is being
incorporated into new rulemaking efforts. There will be no change to
the proposed rule as a result of these comments.
The same commenter is concerned about the phrase in paragraph (i)
that says ``may perform the removal and reinstallation of approved
aircraft cabin-mounted seats. . .'' He suggests that the sentence
should include a reference to maintenance and preventive maintenance,
as stated in the section title, and that the term ``aircraft'' should
again read ``airplane.'' The FAA disagrees. The title of the section is
sufficient without repeating it in paragraph (i); the redundancy would
not clarify the rule language, but would rather make it more
cumbersome. The argument for ``aircraft'' vs. ``airplane'' is addressed
above. There will be no change to the proposed rule as a result of
these comments.
The same commenter suggests that the rule should allow pilots of
part 135 rotorcraft to perform the functions. The FAA agrees and will
retain the term ``aircraft'' in the rule language. The commenter
suggests that the reference to part 135 be removed from Sec. 43.3(g),
which, he states, would eliminate the need for paragraph (h) and (i).
He also suggests that current paragraphs (h) (2), (3), (4), and (5)
should be incorporated into existing paragraph (g), and that existing
paragraph [i] should be redesignated as new paragraph (h). Under this
scheme, existing paragraph (h)(1) would be eliminated. He also suggests
that the new rule should add the removal and reinstallation of
stretchers and cabin-mounted medical oxygen bottles to [paragraph (c)
of] Appendix A. The FAA disagrees. Removing the reference to part 135
from Sec. 43.3(g) would allow pilots to perform any of the tasks listed
in paragraph (c) of Appendix A. The purpose of this rulemaking is to
allow pilots performing specific operations to perform only
[[Page 19500]]
certain tasks relevant to the operation. Pilots are hired to fly
aircraft, not to perform maintenance and preventive maintenance in all
areas on a regular basis. Moreover, the suggestion to incorporate
existing paragraphs (h) (2), (3), (4), and (5) into existing paragraph
(g) would have the unintended effect of having general aviation pilots,
who operate under part 91, meet requirements intended and adopted for
rotorcraft pilots who operate under part 135 in order to perform
preventive maintenance tasks. The suggestion to revise Sec. 43.3(g) is
outside the scope of this rulemaking and no change to the proposal will
be made pursuant to the suggestion.
Two commeters point out that removing and replacing navigation and
communication devices (paragraph (c)(31)) could adversely affect safety
if the connectors are not properly engaged upon reinstallation and no
operational check is performed. The FAA agrees, and has revised the
proposed rule language to reflect that the panel-mounted device must be
a front loading device that employs a tray-mounted connector that
connects the unit when the unit is installed into the instrument panel.
Language has also been added to paragraphs (c)(31) and (c)(32) to
require an operational check prior to use, in accordance with the
applicable sections of part 91. Depending on the type of flight and/or
the type of equipment, a pilot would have to comply with FAA91.407 or
Sec. 91.171.
One of these commenters also suggests that procedures on how to
perform the maintenance task and any testing required to determine if
the equipment is serviceable after maintenance is performed, should be
documented in the aircraft flight manual. The FAA agrees that the
information should be made available to the pilot, but will not
restrict the location of the material to the flight manual. Paragraph
(i)(2) has been revised to require the certificate holder to have
written procedures available to the pilot to evaluate the
accomplishment of the task.
The same commenter states that the tasks permitted in this
rulemaking should be allowed only when there is no maintenance
personnel available. The FAA disagrees. During rulemaking proceedings,
the FAA examined this issue extensively. The definition of
``availability'' is complex enough that in this case, it was determined
that if a pilot is properly trained to perform the tasks, he or she
should be permitted to perform them whenever needed during operations
described in this rulemaking action. Over 250 exemptions have been
granted by the FAA to allow pilots to perform the tasks described here,
with no adverse effect on safety. Therefore, no change will be made to
the proposal as a result of this comment.
International Compatibility
The FAA has reviewed corresponding International Civil Aviation
Organization regulations and Joint Aviation Authority regulations,
where they exist, and has identified no differences in these proposed
amendments and the foreign regulations.
Paperwork Reduction Act
Information collection requirements in the amendment to Sec. 43.3
have been previously approved by the Office of the Management and
Budget (OMB) under the provisions of the Paperwork Reduction Act of
1980 (Pub. L. 96-511) and have been assigned PMB Control Number 2120-
0021. For further information contact: the Information Requirements

Regulatory Evaluation Summary
Executive Order 12866 established the requirement that, within the
extent permitted by law, a Federal regulatory action may be undertaken
only if the potential benefits to society for the regulation outweigh
the potential costs to society. In response to this requirement, and in
accordance with Department of Transportation policies and procedures,
the FAA has estimated the anticipated benefits and costs of this
rulemaking action. The FAA has determined that this rule change is not
a significant rulemaking action as defined by Executive Order 12866
(Regulatory Planning and Review). The results are summarized in this
section. For more detailed economic information, see the full
regulatory evaluation contained in the docket.
This rule is cost relieving because it eliminates the need for
operators to carry mechanics on trips to remote areas or make special
trips to maintenance facilities for the purpose of altering seat
configurations or exchanging medical oxygen bottles. Currently, even if
a mechanic is not needed on a regular basis at a remote site, operators
may have to hire the services of a local mechanic to reconfigure a
cabin, which can be especially expensive for emergency medical
evacuation operations conducted at night during off-duty hours. For the
purposes of this regulatory evaluation, the FAA assumes that typical
air taxi operators that fly into remote areas where mechanics are
scarce could make 36 trips per year that require cabin configuration.
The FAA further assumes that a pilot flying into a remote area has to
fly the airplane for an additional hour (roundtrip) to a larger airport
where a mechanic is available to perform the required maintenance.
The FAA estimates that a mechanic will have to be paid for \1/2\
hour of working time at a loaded wage rate (including benefits) of
$18.16 per hour. The FAA also estimates that, in the event a cabin
reconfiguration is needed in a remote area, the airplane burns an
additional 30 gallons of fuel during the one hour of flying time needed
to reach an available mechanic, which adds $60 to operating costs. The
additional cost per trip amounts to $69. On an annual basis, these
cost-savings amount to $2,484 ($69 x 36) based on the assumption of 36
trips per year. The FAA further estimates that at least 30 operators
per year have a recurring need to reconfigure cabins in remote areas
based on the number of requests for exemption from the requirements of
Sec. 43.3 submitted to the FAA each year. This number is a very
conservative estimate; many air taxi operators are unaware of this
option and forego the additional revenue that could be earned through
reconfiguring their cabins. The FAA estimates that industry-wide cost
savings from the proposed rule amendment amount to $74,520 per year
($2,484 x 30). Over a 10-year period, the discounted value of these
cost savings amounts to $523,382.
Since January 1987, part 135 rotorcraft operators have been
permitted to allow their pilots to perform certain preventive
maintenance tasks, under very limited specified conditions, one of
which is that the item of preventive maintenance must be the result of
a malfunction that occurred en route to or in a remote area. In
addition, numerous exemptions that permitted pilots of aircraft
operating under part 135 to reconfigure cabins were granted to
operators of rotorcraft. Each of the above authorizations contained a
requirement that the pilot be properly trained for the preventive
maintenance task that would be undertaken. Rotorcraft pilots operating
under part 91 rules are authorized to perform preventive maintenance
tasks under Sec. 43.3(g).
National Transportation Safety Board (NTSB) accident reports reveal
no instance of rotorcraft accidents where the removal and replacement
of cabin seats by a rotorcraft pilot was suspected as a possible cause.
In fact, a search of the FAA and NTSB accident and incident data
recorded for part 91 and
[[Page 19501]]
part 135 operations over the 1972-present period did not reveal a
single instance in which the performance by a pilot of any of the tasks
that would be authorized in this final rule were suspected as having
had a causal role in an accident. The FAA has therefore determined that
this final rule is cost relieving and will not reduce the current level
of safety.
In the NPRM, the FAA solicited information from the public to
refine its estimate of cost savings. No comments were received.
International Trade Impact Analysis
This rule will affect only those operators engaged in part 135
operations of a localized or regional nature. No impact is expected on
international trade because these domestic operators seldom compete
with foreign firms in the markets they serve.
Regulatory Flexibility Determination
The Regulatory Flexibility Act of 1980 (RFA) was enacted by
Congress to ensure that small entities are not unnecessarily and
disproportionately burdened by government regulations. The RFA requires
agencies to review rules that may have ``a significant economic impact
on a substantial number of small entities.'' This final rule is of a
cost relieving nature and will therefore afford cost savings to
individual part 135 operators.
Under FAA Order 2100.14A, the criterion for a ``substantial
number'' is a number that is not less than 11 and that is more than one
third of the small entities subject to the rule. This rule will affect
all part 135 operators who operate aircraft type certificated for 9 or
fewer passenger seats. For operators of aircraft for hire, a small
operator is one that owns, but not necessarily operates, nine or fewer
aircraft.
The FAA's criterion for a ``significant impact'' is $4,330 or more
per year for a unscheduled operator. The extent of the cost savings per
operator is estimated at $2,484 per operator in the section on economic
impacts. The FAA concludes, therefore, that this rule will not have a
significant economic impact, positive or negative, on a substantial
number of small entities.
Federalism Implications
This final rule will not have substantial direct effects on the
States, on the relationship between the national government and the
States, or on the distribution of power and responsibilities among the
various levels of government. Therefore, in accordance with Executive
Order 12612, it is determined that this rule will not have sufficient
federalism implications to warrant the preparation of a Federalism
Assessment.
Conclusion
For the reasons discussed in the preamble, and based on the
findings in the Regulatory Flexibility Determination and the
International Trade Impact Analysis, the FAA has determined that this
final rule is not a significant regulatory action under Executive Order
12866. In addition, the FAA certifies that this final rule will not
have a significant economic impact, positive or negative, on a
substantial number of small entities under the criteria of the
Regulatory Flexibility Act. This rule is considered nonsignificant
under Order DOT 2100.5, Policies and Procedures for Simplification,
Analysis, and Review of Regulations. A regulatory evaluation of the
rule, including an initial Regulatory Flexibility Determination and
International Trade Impact Analysis, has been placed in the docket. A
