Airworthiness Directives; Bell Textron Canada Limited Helicopters
Document Number: 2021-10909
Type: Proposed Rule
Date: 2021-05-25
Agency: Federal Aviation Administration, Department of Transportation
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bell Textron Canada Limited Model 505 helicopters. This proposed AD was prompted by three occurrences of metallic debris in the engine oil lubrication system causing the 12 volts direct current (VDC) reference voltage to be shorted to ground and loss of important flight information to the pilot. This proposed AD would require replacing a certain part-numbered relay panel assembly. The FAA is proposing this AD to address the unsafe condition on these products.
