Airworthiness Directive · Amendment 39-10810 · Fokker Model F27 Mark 050, 100, 200, 300, 400, 500, 600, and 700 Rough Field Version (RFV) Series Airplanes
Fokker Model F27 Mark 050, 100, 200, 300, 400, 500, 600, and 700 Rough Field Version (RFV) Series Airplanes
Model F27 Mark 050, 100, 200, 300, 400, 500, 600, and 700 Rough Field Version (RFV) series airplanes, equipped with Dowty Aerospace MLG Legs, part and serial numbers as listed in Dowty Aerospace Landing Gear Service Bulletin 32-77W, Revision 4, dated February 3, 1993, or Dowty Aerospace Landing Gear Service Bulletin F50-32-27, Revision 4, dated December 18, 1992; certificated in any category.
This amendment supersedes an existing airworthiness directive (AD), applicable to certain Fokker Model F27 Mark 100, 200, 300, 400, 500, 600, and 700 Rough Field Version (RFV) series airplanes, that currently requires inspection of the main landing gear (MLG) legs to determine if parts are missing or damaged, and modification, if necessary; and periodic measurements of the extension of each MLG shock absorber sliding member. That AD also provides for the accomplishment of a certain modification as optional terminating action for the periodic measurements. This amendment requires accomplishment of the previously optional terminating action, and revises the applicability of the existing AD to add an airplane model. 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 loss of the MLG sliding member, which could result in reduced structural integrity of the MLG.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
