Airworthiness Directive · Amendment 39-13457 · Bombardier Model CL-215-1A10 and CL-215-6B11 Series Airplanes
Bombardier Model CL-215-1A10 and CL-215-6B11 Series Airplanes
Model CL-215-1A10 (piston) and CL-215-6B11 (turboprop) series airplanes, having serial numbers 1001 through 1125 inclusive, certificated in any category.
This amendment supersedes an existing airworthiness directive (AD), applicable to certain Bombardier Model CL-215-1A10 and CL-215- 6B11 series airplanes, that currently requires repetitive inspections to detect cracking of main landing gear (MLG) axles that have been reworked by chromium plating, and replacement of cracked axles with serviceable axles. This amendment requires a dimensional check and follow-on corrective actions, mandates terminating action for certain airplanes, and adds three airplanes to the applicability in the existing AD. The actions specified by this AD are intended to prevent cracking of the inner bearing surface of the MLG axles, which could result in failure of an axle, subsequent separation of the wheel from the airplane, and consequent reduced controllability of the airplane during takeoff or landing. This action is intended to address the identified unsafe condition.
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.
