Airworthiness Directive · Amendment 39-14516 · Fokker Model F.28 Mark 0070 and 0100 Airplanes
Fokker Model F.28 Mark 0070 and 0100 Airplanes
Superseded. A later AD replaced this one: AD 2008-20-03. Comply with the one in force.
This AD applies to Fokker Model F.28 Mark 0070 and 0100 airplanes, certificated in any category; equipped with Messier-Dowty main landing gears (MLGs).
The FAA is adopting a new airworthiness directive (AD) for certain Fokker Model F.28 Mark 0070 and 0100 airplanes. This AD requires inspecting the main landing gear (MLG) main fitting for cracks, and repair if necessary. This AD also requires installing a placard and revising the airplane flight manual to include procedures to prohibit the application of brakes during backward movement of the airplane. This AD results from a report that an MLG main fitting failed on an airplane that was braking while moving backward. We are issuing this AD to detect and correct cracks in the MLG main fitting, which could result in reduced structural integrity of the MLG main fitting.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 14 days after the effective date of this AD, amend the Limitations section of the Fokker F.28 AFM to prohibit application of brakes during backward movement of the airplane. This may be done by inserting a copy of this AD in the AFM.
Note 1: When a statement to prohibit application of brakes during backward movement of the airplane has been included in the general revisions of the AFM, the general revisions may be inserted into the AFM, and the copy of this AD may be removed from the AFM.
(g) Within 14 days after the effective date of this AD, affix a placard on the pedestal, next to the parking brake handle, having the following wording: “APPLICATION OF BRAKES DURING BACKWARD MOVEMENT IS PROHIBITED.”
At the applicable time specified in paragraph (h)(1) or (h)(2) of this AD: Do an eddy current inspection of the MLG main fittings and repair before further flight as applicable, in accordance with the Accomplishment Instructions of Messier-Dowty Service Bulletin F100-32-106, including Appendices A through C and excluding Appendix D, dated February 18, 2005, except as provided by paragraphs (i) and (j) of this AD.
(1) For airplanes on which an inspection has not been done in accordance with Messier-Dowty Service Bulletin F100-32-104, Revision 2, dated October 30, 2003: Within 3 months after the effective date of this AD.
(2) For airplanes on which an inspection has been done in accordance with Messier-Dowty Service Bulletin F100-32-104, Revision 2, dated October 30, 2003: Within 2,000 flight cycles since the last inspection done in accordance with the service bulletin or within 3 months after the effective date of this AD, whichever occurs later.
(i) Where Messier-Dowty Service Bulletin F100-32-106, including Appendices A through C and excluding Appendix D, dated February 18, 2005, specifies contacting the manufacturer for repair: Before further flight, repair using a method approved by either the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA; or the Civil Aviation Authority—The Netherlands (CAA-NL) (or its delegated agent).
(j) Although Messier-Dowty Service Bulletin F100-32-106, including Appendices A through C and excluding Appendix D, dated February 18, 2005, specifies to submit certain information to the manufacturer, this AD does not include that requirement.
As of the effective date of this AD, no person may install, on any airplane, a Messier-Dowty MLG, unless it has been inspected/repaired according to paragraph (h) of this AD.
