Airworthiness Directive 2009-22-11
one-timeAirworthiness Directives; Bell Helicopter Textron Canada Model 407 and 427 Helicopters
What this AD requires
We are adopting a new airworthiness directive (AD) for Bell Helicopter Textron Canada (Bell) Model 407 and 427 helicopters. This AD results from a mandatory continuing airworthiness information (MCAI) AD issued by the aviation authority of Canada. The MCAI AD states that, during a preflight check, it was observed that the swashplate link assembly bearing had moved in the lever race, making contact with the swashplate support. The MCAI also states that further investigation revealed that the bearing had not been staked correctly during manufacture. That condition, if not detected, could result in failure of a bearing, failure of the swashplate link assembly, and subsequent loss of control of the helicopter.
Which aircraft AD 2009-22-11 applies to
Applies only to Model 407 and 427 helicopters with anti-drive (swashplate) link assembly P/N 406-010-432-101 having a serial number prefix of 'TI' or 'TIFS' installed.
Whether AD 2009-22-11 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.
