BAE Systems (Operations) Limited Airplanes

This amendment adopts a new airworthiness directive (AD) that is applicable to certain Jetstream Model ATP airplanes. This action requires inspections to detect cracking in certain oil coolers, and replacement of cracked coolers with serviceable coolers. The amendment also provides for termination of the inspections by installing certain reworked and re-identified oil coolers. This amendment is prompted by reports of cracking in the welded seams of certain oil coolers. The actions specified in this AD are intended to prevent loss of engine oil due to cracking in the oil cooler, which may lead to a forced shutdown of the engine.
