14 CFR Part 39

[Docket No. 93-NM-196-AD]

 

Airworthiness Directives; Fokker Model F28 Mark 0100 Series 
Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Proposed rule; withdrawal.

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

SUMMARY: This action withdraws a notice of proposed rulemaking (NPRM) 
that proposed a new airworthiness directive (AD), applicable to certain 
Fokker Model F28 Mark 0100 series airplanes. That action would have 
required replacement of certain main landing gear (MLG) torque link 
dampers. Since the issuance of the NPRM, the Federal Aviation 
Administration (FAA) has received new data indicating that the proposed 
actions have been accomplished on all affected airplanes; therefore, 
the previously identified unsafe condition no longer exists. 
Accordingly, the proposed rule is withdrawn.

FOR FURTHER INFORMATION CONTACT: Timothy J. Dulin, Aerospace Engineer, 
Standardization Branch, ANM-113, FAA, Transport Airplane Directorate, 
1601 Lind Avenue, SW., Renton, Washington 98055-4056; telephone (206) 
227-2141; fax (206) 227-1320.

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal 
Aviation Regulations (14 CFR part 39) to add a new airworthiness 
directive (AD), applicable to certain Fokker Model F28 Mark 0100 series 
airplanes, was published in the Federal Register on February 1, 1994 
(59 FR 4607). The proposed rule would have required replacement of 
suspect main landing gear (MLG) torque link dampers with serviceable 
dampers. That action was prompted by a report that certain MLG torque 
link dampers may have been assembled with incorrect parts. The proposed 
actions were intended to prevent loss of the damping characteristics of 
the torque link damper, which could lead to the loss of the MLG wheel 
assembly of the aircraft during takeoff or landing.
    Since the issuance of that NPRM, Menasco, the manufacturer of the 
suspect MLG torque link dampers, has provided evidence to the FAA that 
the proposed requirement to replace suspect MLG torque link dampers has 
been accomplished on all affected airplanes. (Evidence was provided to 
the FAA in Menasco's facsimile, dated February 10, 1994, which is 
contained in the Rules Docket.)
    Based on this evidence, the FAA has determined that the previously 
identified unsafe condition no longer exists with regard to Fokker 
Model F28 Mark 0100 series airplanes. Accordingly, the proposed rule is 
hereby withdrawn.
    Withdrawal of this notice of proposed rulemaking constitutes only 
such action, and does not preclude the agency from issuing another 
notice in the future, nor does it commit the agency to any course of 
action in the future.
    Since this action only withdraws a notice of proposed rulemaking, 
it is neither a proposed nor a final rule and therefore, is not covered 
under Executive Order 12866, the Regulatory Flexibility Act, or DOT 
Regulatory Policies and Procedures (44 FR 11034, February 26, 1979).
