This amendment adopts a new airworthiness directive (AD) for the Aeronautical Accessories, Inc. (AAI) Low Skid Landing Gear Forward Crosstube (crosstube) installed on the specified helicopters. This action requires replacing certain AAI serial-numbered crosstubes installed on these model helicopters. This amendment is prompted by the discovery of a defect in the raw material used in manufacturing certain crosstubes. The actions specified in this AD are intended to prevent failure of a crosstube and subsequent collapse of the landing gear.
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.
