Airworthiness Directive 2017-05967
one-timeAirworthiness Directives; Sikorsky Aircraft Corporation Helicopters
What this AD requires
We are adopting a new airworthiness directive (AD) for Sikorsky Aircraft Corporation (Sikorsky) Model 269D and Model 269D Configuration A helicopters. This AD requires reducing the life limit of and inspecting certain drive shafts. This AD is prompted by four incidents involving failure of a drive shaft. The actions specified by this AD are intended to prevent the unsafe condition on these products.
Which aircraft AD 2017-05967 applies to
Applies only to helicopters with a KAflex engine side drive shaft P/N SKCP2738-7 and KAflex pulley side drive shaft P/N SKCP2738-5 installed.
Whether AD 2017-05967 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
