Airworthiness Directive · Amendment 39-9411 · Bombardier Inc. Airplanes
Bombardier Inc. Airplanes
Superseded. A later AD replaced this one: AD 2004-03-13. Comply with the one in force.
This AD applies to Bombardier Inc. CL-215-1A10, CL-215-6B11 (CL-215T Variant), CL-215-6B11 (CL-415 Variant).
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment adopts a new airworthiness directive (AD), applicable to certain Canadair Model CL-215-1A10 and CL-215-6B11 series airplanes. This action requires inspections to detect cracking of main landing gear (MLG) axles that have been reworked by chromium plating, and replacement of cracked axles. This amendment is prompted by reports of fatigue cracking found on several MLG wheel axes that had been chromium-plated during rework. The actions specified in this AD are intended to prevent such cracking, which can result in failure of the axle, separation of the wheel from the aircraft, and consequent reduced controllability of the airplane during takeoff or landing.
