Airworthiness Directives; British Aerospace Model BAe 146 and Model Avro 146-RJ Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain British Aerospace Model BAe 146 and Model Avro 146-RJ series airplanes, that requires a one-time measurement to determine the thickness of the outer links of the side stays of the main landing gear (MLG), and corrective actions, if necessary. This amendment also provides for replacement of a thin outer link with a new or serviceable part in lieu of certain follow-on inspections. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent cracking of the outer links of the side stays of the MLG, which could result in failure of a side stay, and consequent collapse of the landing gear.
