This amendment adopts a new airworthiness directive (AD), applicable to certain Aerospatiale Model ATR72 series airplanes, that requires inspections to detect cracking in the brake side half hub in the bearing housing area of certain main landing gear (MLG) wheels, and replacement of the MLG wheel, if necessary. This amendment also requires the eventual replacement of certain MLG wheels with other wheels, as terminating action for the repetitive inspections. This amendment is prompted by in-service experience that indicates the possibility of fatigue cracking occurring in the subject area. The actions specified by this AD are intended to prevent failure of the brake side half hub due to fatigue cracking, which could lead to separation of the MLG wheel and tire from the axle.
