[Docket No. 94-NM-128-AD; Amendment 39-9146; AD 95-03-09]
Airworthiness Directives; Fokker Model F28 Mark 0100 Series
Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD),
applicable to all Fokker F28 Mark 0100 series airplanes, that requires
inspecting the teleflex cable of the landing gear to detect corrosion,
moisture, or improper greasing, and replacing discrepant teleflex
cables with serviceable parts. This amendment is prompted by reports of
difficulties with the operation of the selector handle of the landing
gear when ``gear down'' is selected, due to improper greasing of the
teleflex cable of the landing gear during production. The actions
specified by this AD are intended to prevent moisture from accumulating
on the teleflex cable, which could result in corrosion of the teleflex
cable that could inhibit operation of the selector handle of the
landing gear.
DATES: Effective March 30, 1995.-
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of March 30, 1995.
ADDRESSES: The service information referenced in this AD may be
obtained from Fokker Aircraft USA, Inc., 1199 North Fairfax Street,
Alexandria, Virginia 22314. 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 Fokker Model F28 Mark 0100
series airplanes was published in the Federal Register on October 18,
1994 (59 FR 52479). That action proposed to require removing the
teleflex cable of the landing gear, part number D76351-001, and
inspecting it to detect corrosion, moisture, or improper greasing. If
no discrepancies are detected, the cable would be cleaned, greased, and
reassembled. If any discrepancy is detected, the cable would be
replaced with a serviceable part.
Interested persons have been afforded an opportunity to participate
in the making of this amendment. Due consideration has been given to
the single comment received.
The commenter supports the proposed rule.
As a result of recent communications with the Air Transport
Association (ATA) of America, the FAA has learned that, in general,
some operators may misunderstand the legal effect of AD's on airplanes
that are identified in the applicability provision of the AD, but that
have been altered or repaired in the area addressed by the AD. The FAA
points out that all airplanes identified in the applicability provision
of an AD are legally subject to the AD. If an airplane has been altered
or repaired in the affected area in such a way as to affect compliance
with the AD, the owner or operator is required to obtain FAA approval
for an alternative method of compliance with the AD, in accordance with
the paragraph of each AD that provides for such approvals. A note has
been added to this final rule to clarify this requirement.
Additionally, the applicability of the final rule has been revised
to clarify that only airplanes equipped with a teleflex cable of the
landing gear, having part number D76351-001, are applicable to the
requirements of the AD.
The FAA has recently reviewed the figures it has used over the past
several years in calculating the economic impact of AD activity. In
order to account for various inflationary costs in the airline
industry, the FAA has determined that it is necessary to increase the
labor rate used in these calculations from $55 per work hour to $60 per
work hour. The economic impact information, below, has been revised to
reflect this increase in the specified hourly labor rate.
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 with the change previously
described. The FAA has determined that this change will neither
increase the economic burden on any operator nor increase the scope of
the AD.
The FAA estimates that 119 airplanes of U.S. registry will be
affected by this AD, that it will take approximately 10.9 work hours
per airplane to accomplish the required actions, and that the average
labor rate is $60 per work hour. Required parts will be supplied by the
manufacturer at no cost to the operators. Based on these figures, the
total cost impact of the AD on U.S. operators is estimated to be
$77,826, or $654 per airplane.
The total 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.
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, 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. App. 1354(a), 1421 and 1423; 49 U.S.C.
106(g); and 14 CFR 11.89.
Sec. 39.13 [Amended]
2. Section 39.13 is amended by adding the following new
airworthiness directive:
95-03-09 Fokker: Amendment 39-9146. Docket 94-NM-128-AD.
Applicability: Model F28 Mark 0100 series airplanes; equipped
with a teleflex cable of the landing gear, having part number
D76351-001; 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 use the authority
provided in paragraph (b) to request approval from the FAA. This
approval may address either no action, if the current configuration
eliminates the unsafe condition; or different actions necessary to
address the unsafe condition described in this AD. Such a request
should include an assessment of the effect of the changed
configuration on the unsafe condition addressed by this AD. In no
case does the presence of any modification, alteration, or repair
remove any airplane from the applicability of this AD.
Compliance: Required as indicated, unless accomplished
previously.
To prevent moisture from accumulating on the teleflex cable,
which could result in corrosion of the teleflex cable that could
inhibit operation of the selector handle of the landing gear,
accomplish the following:
(a) Within 4 months after the effective date of this AD, remove
the teleflex cable of the landing gear, part number D76351-001, and
perform an inspection of it to detect corrosion, moisture, or
improper greasing, in accordance with Fokker Service Bulletin
SBF100-32-071, dated June 22, 1993.
(1) If no discrepancies are found, prior to further flight,
clean, grease, and reinstall the teleflex cable, in accordance with
the service bulletin.
(2) If any discrepancy is found, prior to further flight,
replace the teleflex cable with a serviceable part in accordance
with the service bulletin.
(b) An alternative method of compliance or adjustment of the
compliance time that provides an acceptable level of safety may be
[[Page 10803]] used if approved by the Manager, Standardization
Branch, ANM-113, FAA, Transport Airplane Directorate. Operators
shall submit their requests through an appropriate FAA Principal
Maintenance Inspector, who may add comments and then send it to the
Manager, Standardization Branch, ANM-113.
Note 2: Information concerning the existence of approved
alternative methods of compliance with this AD, if any, may be
obtained from the Standardization Branch, ANM-113.
(c) Special flight permits may be issued in accordance with
Secs. 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.
(d) The actions shall be done in accordance with Fokker Service
Bulletin SBF100-32-071, dated June 22, 1993. 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
obtained from Fokker Aircraft USA, Inc., 1199 North Fairfax Street,
