Airworthiness Directives; Airbus Model A310 and A300-600 Series
Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD),
applicable to all Airbus Model A310 and A300-600 series airplanes, that
requires a one-time visual inspection to determine the accuracy of the
outer placards of the static ports. This amendment also requires a one-
time inspection to detect crossed connections of the air data static
system and the static probe heating system, and correction of any
discrepancies. This amendment is prompted by issuance of mandatory
continuing airworthiness information by a foreign civil airworthiness
authority. The actions specified by this AD are intended to prevent
erroneous display of altitude information to the flight crew, and
consequent reduced operational safety during all phases of flight.
DATES: Effective April 10, 1998.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of April 10, 1998.
ADDRESSES: The service information referenced in this AD may be
obtained from Airbus Industrie, 1 Rond Point Maurice Bellonte, 31707
Blagnac Cedex, France. This information may be examined at the Federal
Aviation Administration (FAA), Transport Airplane Directorate, Rules
Docket, 1601 Lind Avenue, SW., Renton, Washington; or at the Office of
the Federal Register, 800 North Capitol Street, NW., suite 700,
Washington, DC.

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal
Aviation Regulations (14 CFR part 39) to include an airworthiness
directive (AD) that is applicable to all Airbus Model A310 and A300-600
series airplanes was published in the Federal Register on November 6,
1997 (62 FR 60049). That action proposed to require a one-time visual
inspection to determine the accuracy of the outer placards of the
static ports. That action also proposed to require a one-time
inspection to detect crossed connections of the air data static system
and the static probe heating system, and correction of any
discrepancies.
Interested persons have been afforded an opportunity to participate
in the making of this amendment. Due consideration has been given to
the comments received.
Support for the Proposal
One commenter supports the proposed rule.
Request for Change of Applicability
One commenter requests that the applicability of the AD be revised
to exclude airplanes manufactured after the issuance of Airbus All
Operators Telex (AOT) 34-04, dated July 16, 1996. The commenter states
that, since the issuance of that AOT, the manufacturer has corrected
assembly line faults that had resulted in the cross-connection of
static lines and probe heat wiring (which is the unsafe condition
identified in this AD).
The FAA does not concur that the applicability should be changed.
The FAA finds that, based on information provided by the manufacturer,
there is no available production modification that is equivalent to the
procedures specified in the AOT (which is the appropriate source of
service information for accomplishment of the requirements of this AD).
However, the FAA has verified that the manufacturer performs and
documents the AOT-specified inspections prior to delivery. Therefore,
by means of the phrase, ``Required as indicated, unless accomplished
previously'' in the Compliance section of this AD, operators are
credited for work already performed; airplanes having delivery records
that document accomplishment of the AOT are not subject to the
requirements of this AD. The FAA has determined that, in light of the
severity of the unsafe condition and the minimal burden on operators,
the applicability of this AD should remain unchanged in order to ensure
compliance.
Conclusion
After careful review of the available data, including the comments
noted above, the FAA has determined that air safety and the public
interest require the adoption of the rule as proposed.
Cost Impact
The FAA estimates that 94 airplanes of U.S. registry will be
affected by this AD, that it will take approximately 5 work hours per
airplane to accomplish the required actions, and that the average labor
rate is $60 per work hour. Based on these figures, the cost impact of
the AD on U.S. operators is estimated to be $28,200, or $300 per
airplane.
The cost impact figure discussed above is based on assumptions that
no operator has yet accomplished any of the requirements of this AD
action, and that no operator would accomplish those actions in the
future if this AD were not adopted.
Regulatory Impact
The regulations adopted herein 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,
[[Page 11114]]
it is determined that this final rule does not have sufficient
federalism implications to warrant the preparation of a Federalism
Assessment.
For the reasons discussed above, I certify that this action (1) is
not a ``significant regulatory action'' under Executive Order 12866;
(2) is not a ``significant rule'' under DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979); and (3) 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. A final evaluation has been prepared for this action
and it is contained in the Rules Docket. A copy of it may be obtained
from the Rules Docket at the location provided under the caption

Adoption of the Amendment
Accordingly, pursuant to the authority delegated to me by the
Administrator, the Federal Aviation Administration amends part 39 of
the Federal Aviation Regulations (14 CFR part 39) as follows:
PART 39--AIRWORTHINESS DIRECTIVES
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
2. Section 39.13 is amended by adding the following new
airworthiness directive:
98-05-13 Airbus: Amendment 39-10374. Docket 97-NM-205-AD.
Applicability: All Model A310 and A300-600 series airplanes,
certificated in any category.
Note 1: This AD applies to each airplane identified in the
preceding applicability provision, regardless of whether it has been
modified, altered, or repaired in the area subject to the
requirements of this AD. For airplanes that have been modified,
altered, or repaired so that the performance of the requirements of
this AD is affected, the owner/operator must request approval for an
alternative method of compliance in accordance with paragraph (d) of
this AD. The request should include an assessment of the effect of
the modification, alteration, or repair on the unsafe condition
addressed by this AD; and, if the unsafe condition has not been
eliminated, the request should include specific proposed actions to
address it.
Compliance: Required as indicated, unless accomplished
previously.
To prevent erroneous display of altitude information to the
flight crew, and consequent reduced operational safety during all
phases of flight, accomplish the following:
(a) Within 600 flight hours after the effective date of this AD,
perform a one-time visual inspection of the outer placards of the
static ports to determine that the identification of the static port
corresponds with the specified position on the aircraft, in
accordance with Airbus All Operators Telex (AOT) 34-04, dated July
16, 1996.
(b) Within 600 flight hours after the effective date of this AD,
perform a one-time visual inspection of the pneumatic connections of
the captain, first officer, and standby air data static systems to
detect cross-connected tubing, and conduct an operational check of
each of the static probe heating systems to detect cross-connected
wiring, in accordance with Airbus AOT 34-04, dated July 16, 1996.
(c) If any discrepancy is found, prior to further flight,
correct the discrepancy in accordance with Airbus AOT 34-04, dated
July 16, 1996.
(d) An alternative method of compliance or adjustment of the
compliance time that provides an acceptable level of safety may be
used if approved by the Manager, International Branch, ANM-116.
Operators shall submit their requests through an appropriate FAA
Principal Maintenance Inspector, who may add comments and then send
it to the Manager, International Branch, ANM-116.
Note 2: Information concerning the existence of approved
alternative methods of compliance with this AD, if any, may be
obtained from the International Branch, ANM-116.
(e) Special flight permits may be issued in accordance with
sections 21.197 and 21.199 of the Federal Aviation Regulations (14
CFR 21.197 and 21.199) to operate the airplane to a location where
the requirements of this AD can be accomplished.
(f) The actions shall be done in accordance with Airbus All
Operators Telex 34-04, dated July 16, 1996. This incorporation by
reference was approved by the Director of the Federal Register in
accordance with 5 U.S.C. 552(a) and 1 CFR part 51. Copies may be
