Bombardier Model DHC-8-102, -103, and -106 Airplanes and Model DHC-8-200 and DHC-8-300 Series Airplanes
This AD applies to Bombardier Model DHC-8-102, DHC-8-103, and DHC-8-106 airplanes and Model DHC-8-200 and DHC-8-300 series airplanes; certificated in any category; serial numbers 003 through 579 inclusive.
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Model DHC-8-102, -103, and -106 airplanes and Model DHC-8-200 and DHC-8-300 series airplanes. This AD requires modifying the main landing gear (MLG) and nose landing gear (NLG) handle assemblies for alternate release and the MLG retaining plate. This AD also requires doing a related investigative action and corrective action if necessary. This AD results from reports of broken or damaged MLG and NLG alternate release cables caused by rubbing and fraying at the cable-to-handle interface. We are issuing this AD to prevent breakage of the MLG and NLG alternate release cables, which, if the normal gear extension fails, could result in the inability to extend the MLG or NLG and consequent collapse of the landing gear during ground maneuvers or upon landing.
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 3,000 flight hours after the effective date of this AD, modify the MLG and NLG handle assemblies for alternate release and the MLG retaining plate, do the related investigative action, and the corrective action as applicable, by accomplishing all the applicable actions specified in the Accomplishment Instructions of Bombardier Service Bulletin 8-32-146, Revision ‘D,’ dated February 7, 2003. Do the corrective action, as applicable, before further flight.
Actions accomplished before the effective date of this AD in accordance with Bombardier Service Bulletin 8-32-146, dated September 10, 1999; Revision ‘A,’ dated January 17, 2001; Revision ‘B,’ dated June 25, 2001; or Revision ‘C,’ dated January 24, 2003; are considered acceptable for compliance with the corresponding action specified in this AD.
As of the effective date of this AD, no person may install any part specified in paragraphs (h)(1), (h)(2), and (h)(3) of this AD, on any airplane.
(1) MLG handle assembly, part number (P/N) 83260042.
(2) NLG handle assembly, P/N 83260020.
(3) MLG retaining plate, P/N 83260043.
