Airworthiness Directive 2007-01-06
one-timeAirworthiness Directives; Bell Helicopter Textron Canada Model 206A, B, L, L-1, L-3, and L-4 Helicopters
What this AD requires
This amendment supersedes an existing airworthiness directive (AD) for the specified Bell Helicopter Textron Canada (BHTC) model helicopters. The existing AD currently requires certain inspections and checks of the tail rotor blade (blade) for a deformation, a crack, and a bent or deformed tail rotor weight (weight). Also, that AD requires, before further flight, replacing each blade with an airworthy blade if a deformation, a crack, or a bent or deformed weight is found. This action contains the same actions as the existing AD and also adds to the applicability certain serial-numbered blades inadvertently omitted from the current AD. This action also requires replacing each affected blade, which is a terminating action. This amendment is prompted by three reports of skin cracks originating near the blade trailing edge balance weight. The actions specified by this AD are intended to prevent blade failure and subsequent loss of control of the helicopter.
Which aircraft AD 2007-01-06 applies to
Applies only to helicopters with a tail rotor blade P/N 206-016-201-131 (Models 206A and 206B) or P/N 206-016-201-133 (Models 206A, 206B, 206L, 206L-1, 206L-3, 206L-4) installed, where the blade serial number bears prefix 'CS' and no 'V' suffix, within extensive specific serial-number ranges listed in the AD's table (source table spans multiple print columns and is truncated/too voluminous to fully enumerate here).
Whether AD 2007-01-06 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.
