Airworthiness Directives; Fokker Model F.28 Mark 0070 and 0100 
Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This amendment adopts a new airworthiness directive (AD), 
applicable to certain Fokker Model F.28 Mark 0070 and 0100 series 
airplanes, that requires a magnetic inspection of the sliding members 
of the main landing gear (MLG) for cracking, and replacement of the 
sliding members with serviceable parts, if necessary. This action is 
necessary to prevent fatigue cracking of the sliding member, which 
could result in possible separation of the MLG from the airplane and 
consequent reduced controllability of the airplane upon landing and 
possible injury to passengers. This action is intended to address the 
identified unsafe condition.

DATES: Effective May 19, 2004.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director

[[Page 19760]]

of the Federal Register as of May 19, 2004.

ADDRESSES: The service information referenced in this AD may be 
obtained from Fokker Services B.V., P.O. Box 231, 2150 AE Nieuw-Vennep, 
the Netherlands. 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.

FOR FURTHER INFORMATION CONTACT: Thomas Rodriguez, Aerospace Engineer, 
International Branch, ANM-116, FAA, Transport Airplane Directorate, 
1601 Lind Avenue, SW., Renton, Washington 98055-4056; telephone (425) 
227-1137; fax (425) 227-1149.

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 certain Fokker Model F.28 Mark 
0070 and 0100 series airplanes was published in the Federal Register on 
January 22, 2004 (69 FR 3039). That action proposed to require a 
magnetic inspection of the sliding members in the main landing gear 
(MLG) for cracking, and replacement of the sliding members with 
serviceable parts, if necessary.

Comments

    Interested persons have been afforded an opportunity to participate 
in the making of this amendment. No comments were submitted in response 
to the proposal or the FAA's determination of the cost to the public.

Explanation of Interim Action

    We consider this AD interim action. If final action is later 
identified, we may consider further rulemaking then. The statement 
identifying this AD as interim action was inadvertently omitted from 
the proposal.

Conclusion

    After careful review of the available data 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.

Cost Impact

    The FAA estimates that 110 airplanes of U.S. registry will be 
affected by this AD, that it will take approximately 4 or 12 work hours 
per airplane, depending on the airplane configuration, to accomplish 
the required inspection, and that the average labor rate is $65 per 
work hour. Based on these figures, the cost impact of the AD on U.S. 
operators is estimated to be $28,600 or $85,800, or $260 or $780 per 
airplane, depending on the airplane configuration.
    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. The cost impact figures discussed 
in AD rulemaking actions represent only the time necessary to perform 
the specific actions actually required by the AD. These figures 
typically do not include incidental costs, such as the time required to 
gain access and close up, planning time, or time necessitated by other 
administrative actions.

Regulatory Impact

    The regulations adopted herein will not have a substantial direct 
effect 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, it 
is determined that this final rule does not have federalism 
implications under Executive Order 13132.
    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 
ADDRESSES.

    Compliance: Required as indicated, unless accomplished 
previously.
    To prevent fatigue cracking of the sliding member, which could 
result in possible separation of the MLG from the airplane and 
consequent reduced controllability of the airplane upon landing and 
possible injury to passengers, accomplish the following:

Inspection and Replacement if Necessary

    (a) Within 1,000 flight cycles or six months after the effective 
date of this AD, whichever occurs first, perform a magnetic 
inspection of the sliding members of the MLG for cracking, in 
accordance with the Accomplishment Instructions of Fokker Service 
Bulletin SBF100-32-133, dated April 1, 2002. If any crack is found 
during the inspection, before further flight, replace the sliding 
members with serviceable parts in accordance with the Accomplishment 
Instructions of the service bulletin.

    Note 1: Fokker Service Bulletin SBF100-32-133, dated April 1, 
2002, refers to Messier-Dowty Service Bulletin F100-32-103, dated 
March 11, 2002, as an additional source of service information.

Parts Installation

    (b) As of the effective date of this AD, no person may install a 
sliding member of the MLG, P/N 201072301 or P/N 201072305, on any 
airplane, unless it has been inspected in accordance with the 
Accomplishment Instructions of Fokker Service Bulletin SBF100-32-
133, dated April 1, 2002, and found to be serviceable.

Reporting Requirement Difference

    (c) Although the service bulletin referenced in this AD 
specifies to submit certain

[[Page 19761]]

information to the manufacturer, this AD does not include such a 
requirement.

Alternative Methods of Compliance

    (d) In accordance with 14 CFR 39.19, the Manager, International 
Branch, ANM-116, FAA, Transport Airplane Directorate, is authorized 
to approve alternative methods of compliance for this AD.
