The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model AS355E, AS355F, AS355F1, AS355F2, and AS355N helicopters. This proposed AD was prompted by the determination that the tail rotor drive fan wheels (fan wheels) and the impeller second stage have been incorrectly identified during production. This proposed AD would require verifying the serial number and amendment of the log cards of the affected parts, and depending on the findings, performing a one-time borescope inspection to verify consistency between the log cards and the affected parts. Depending on the inspection results, this proposed AD would require replacing or re- identifying certain parts. This proposed AD would also prohibit the installation of certain fan wheels and impeller second stages on any helicopter. The FAA is proposing this AD to address the unsafe condition on these products.
