Abstract
The FAA is adopting a new airworthiness directive (AD) for certain Aerospatiale Model ATR42 and ATR72 airplanes. This AD requires an inspection of the locking bolt of the upper attachment pin of the shock absorber on both main landing gears (MLGs) for the correct installation of the locking bolt and for any missing locking bolt, washer, nut, cotter pin, or compound, and applicable corrective action if necessary. This AD results from a report of migration and subsequent rupture of the attachment pin of the shock absorber of a MLG. We are issuing this AD to prevent failure of a MLG, which could result in significant structural damage to the airplane and possible injury to the occupants.
