FR doc E9-29427

AD 2009-25-08Published 2009-12-11Effective 2009-12-28

Prompted by mandatory continuing airworthiness information (MCAI) ADs issued by the aviation authority of Canada.

Full official abstract

We are adopting a new airworthiness directive (AD) for the BHTC Model 407 and Model 427 helicopters. This AD results from mandatory continuing airworthiness information (MCAI) ADs issued by the aviation authority of Canada. The MCAI ADs state that some hydraulic pump driveshaft assemblies may have been delivered with a missing internal plug or fastening rivet. This condition, if not corrected, could result in a loss of hydraulic pressure and subsequent loss of control of the helicopter.
