Airworthiness Directive E9-7783
one-timeAirworthiness Directives; Bell Helicopter Textron Canada Limited Model 206A, 206B, 206L, 206L-1, 206L-3, 206L-4, 222, 222B, 222U, 230, 407, 427, and 430 Helicopters
What this AD requires
We are adopting a superseding airworthiness directive (AD) for the specified Bell Helicopter Textron Canada Limited (BHTC) Model 206A, 206B, 206L, 206L-1, 206L-3, 206L-4, 222, 222B, 222U, 230, 407, 427, and 430 helicopters. That AD currently requires replacing each affected tail rotor blade (blade) with an airworthy blade that has a serial number not listed in the Rotor Blades, Inc. (RBI) document that is attached to each of the Bell Helicopter Textron Alert Service Bulletins (ASBs) listed in the applicability section of the AD. That AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of Canada. The MCAI states that there have been three reports of blade tip weights departing from the blade during flight. Since issuing that AD, BHTC has issued revised service information to correct part numbers and serial numbers listed in the RBI document that is attached to each BHTC ASB and to add additional part-numbered and serial-numbered blades to the list. The actions of this AD are intended to prevent loss of a blade tip weight, loss of a blade, and subsequent loss of control of the helicopter.
Which aircraft AD E9-7783 applies to
Applies only to helicopters with a tail rotor blade installed whose part number and serial number are listed in the Rotor Blades, Inc. (RBI) document attached to the applicable Bell Helicopter Textron Alert Service Bulletin (206-07-116 Rev A; 206L-07-148 Rev A; 222-07-106 Rev C; 222U-07-77 Rev C; 230-07-38 Rev C; 407-07-81 Rev A; 427-07-18 Rev A; 430-07-41 Rev C).
Whether AD E9-7783 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
Supersession
Supersedes AD 2007-19-52.
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.
