BAE Systems (Operations) Limited Airplanes
This AD applies to BAE Systems (Operations) Limited ATP.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment adopts a new airworthiness directive (AD) that is applicable to certain Jetstream Model BAe ATP airplanes. This action requires modification of the electrical connections at the switches of the scavenge oil filter and pressure oil filter. This amendment is prompted by reports indicating that the electrical connections were miswired at the switches of the scavenge oil filter and pressure oil filter. The actions specified in this AD are intended to prevent the circulation of unfiltered oil through the engine without warning to the flightcrew, due to miswiring of electrical connections. Unfiltered oil containing contaminants could lead to a precautionary shutdown of the engine.
