Airworthiness Directive 2013-03-16
one-timeAirworthiness Directives; Bell Helicopter Textron Helicopters
What this AD requires
We are superseding an existing airworthiness directive (AD) for the Bell Helicopter Textron (Bell) Model 212 helicopters and adopting requirements for Bell Model 204B, 205A, 205A-1, 205B and 210 helicopters with certain part-numbered main rotor hub inboard strap fittings (fittings). This AD requires magnetic particle inspecting (MPI) the fittings for a crack, and if a crack exists, replacing the fittings with airworthy fittings. This AD is prompted by reports of additional cracked fittings and the determination that additional part-numbered fittings may not have been manufactured in accordance with approved manufacturing processes and controls. These actions are intended to identify a crack in the fitting, which may lead to the fitting's failure, loss of a main rotor blade, and subsequent loss of helicopter control.
Which aircraft AD 2013-03-16 applies to
Applies per Table 1 by fitting P/N: 204-012-102-001 (204B, all S/Ns); 204-012-102-005 (204B/205A/205A-1, all S/Ns); 204-012-102-009 (204B/205A/205A-1, all S/Ns except 7500 or larger with prefix 'A'); 212-010-103-005 (212, all S/Ns); 212-010-103-007 (212, all S/Ns except 140 or larger with prefix 'SH' and 11021 or larger with prefix 'A'); 212-010-103-101 (205A-1/205B/210, all S/Ns except 486 or larger with prefix 'SH' and 10997 or larger with prefix 'A'). Supersedes AD 2011-08-01.
Whether AD 2013-03-16 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.
