Airworthiness Directive 2006-08-07
one-timeAirworthiness Directives; Brantly International, Inc. Model B-2, B-2A, and B-2B Helicopters
What this AD requires
This amendment adopts a new airworthiness directive (AD) for the specified Brantly International, Inc. (Brantly) model helicopters. This action requires certain inspections and measurements of the upper tail rotor vertical gearbox (gearbox), vertical shaft (shaft) and shaft housing (housing) and their associated parts; and of the intermediate gear box bushing (bushing). This amendment is prompted by an accident and an incident report of fatigue cracking of a shaft. The actions specified in this AD are intended to prevent fatigue cracking of a shaft, failure of a shaft, and subsequent loss of control of the helicopter.
Which aircraft AD 2006-08-07 applies to
Applies to helicopters with serial number 2001 and larger, with a vertical shaft P/N 249-10 installed, or any serial-numbered helicopter with a shaft P/N 249-10 that was purchased after 1994. Certificated in any category.
Whether AD 2006-08-07 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.
