Summary
The FAA proposes to adopt a new airworthiness directive (AD) for all Leonardo S.p.A. Model A119 and AW119 MKII helicopters. This proposed AD was prompted by reports that certain fuel control units (FCU) may not have been calibrated to specification during overhaul. This proposed AD would require revising the rotorcraft flight manual (RFM) for your helicopter and installing a placard to prohibit intentional entry into autorotation. This proposed AD would also allow replacement of an affected FCU as an optional terminating action for the RFM revision and placard installation. The FAA is proposing this AD to address the unsafe condition on these products.
