Airworthiness Directive 2000-06-10
recurringAirworthiness Directives; Bell Helicopter Textron Canada Model 407 Helicopters
What this AD requires
This amendment adopts a new airworthiness directive (AD) applicable to Bell Helicopter Textron Canada (BHTC) Model 407 helicopters. This action requires preflight checking and repetitively inspecting the tail boom for a crack and replacing the tail boom if a crack is found. This amendment is prompted by four reports of cracks on the tail boom in the area of the horizontal stabilizer. The actions specified in this AD are intended to prevent separation of the tail boom and subsequent loss of control of the helicopter.
Which aircraft AD 2000-06-10 applies to
Tail boom crack inspection (daily visual check, plus repetitive 10X-magnification inspection for tail booms with 600+ hours TIS). Per Bell Alert SB 407-99-26, dated Apr 13, 1999.
Whether AD 2000-06-10 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.
