Aerospatiale Model ATR 42-200, -300, and -320 Series Airplanes
This AD applies to all Aerospatiale Model ATR 42-200, -300, and -320 series airplanes; certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Aerospatiale Model ATR 42-200, -300, and -320 series airplanes. This AD requires inspecting to determine the part and serial number of the swinging lever of the main landing gears (MLG) and replacing the swinging lever if necessary. This AD is prompted by a report that, on an airplane lined up for takeoff, the swinging lever of the left MLG collapsed when engine power was applied. We are issuing this AD to prevent fracture of the MLG swinging lever, which could result in collapse of the swinging lever and reduced structural integrity and possible collapse of the MLG during operations on the ground.
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 30 days after the effective date of this AD, inspect to determine the part number (P/N) and serial number (S/N) of the swinging lever of the MLG.
(1) If the P/N of the swinging lever is not D56771; or if the P/N of the swinging lever is D56771 but the S/N is not from 115 to 151 inclusive; no further action is required by this paragraph.
(2) If the P/N of the swinging lever is D56771 and the S/N is from 115 to 151 inclusive, within 90 days after the effective date of this AD: Remove the swinging lever and replace it with a new or serviceable lever in accordance with Job Instruction Card 32-11-00 RAI 10030-001, dated February 1, 2000, of the Avions de Transport Regional 42 Aircraft Maintenance Manual.
Though French airworthiness directive 2003-376(B), dated October 1, 2003, specifies that operators shall report certain inspection findings to Messier-Dowty, this AD does not require this.
Though French airworthiness directive 2003-376(B), dated October 1, 2003, specifies that operators shall return swinging levers with applicable serial numbers to Messier-Dowty for discard, this AD does not require this.
(i) As of the effective date of this AD, no person may install on any airplane an MLG swinging lever, P/N D56771, having a S/N from 115 to 151 inclusive.
