Airworthiness Directive

May 1, 2013 - 10:50am

The FAA has issued a final rule superseding an existing airworthiness directive (AD) for all Pilatus PC-12s, PC-12/45s, PC-12/47s and PC-12/47Es. Since the issuance of AD 2009-14-13 Pilatus has issued revisions to the limitations section of the airplane maintenance manual to include an inspection of the wing main spar fastener holes at rib six for cracks. The action was prompted by a crack found on one wing, and a more restrictive airworthiness limitation was introduced in that manual.

The FAA proposes to supersede an existing airworthiness directive for the Robinson R22, R22 Alpha, R22 Beta, R22 Mariner, R44 and R44 II with certain main rotor blades. The existing AD currently requires inspecting each blade at the skin-to-spar line for debonding, corrosion, a separation, a gap or a dent and replacing any damaged blade with an airworthy blade.

The FAA is superseding an existing airworthiness directive for the Bell 212 and adopting requirements for Bell 204B, 205A, 205A-1, 205B and 210 helicopters with certain part-numbered main rotor hub inboard strap fittings. The AD requires magnetic particle inspection of the fittings for a crack, and if a crack exists, replacing the fittings with airworthy fittings.

The FAA has adopted a new Airworthiness Directive (AD) for all AgustaWestland A109, A109A, A109A II, A109C, A109K2, A109E, A109S and A119 helicopters. It was prompted by the failure of the tail rotor pitch control link assembly on an A109E, caused by a production defect. The AD requires inspecting the link assembly for freedom of movement and taking corrective action if rotation resistance or binding occurs.

The FAA is adopting an airworthiness directive (AD) for the Cessna 750 Citation X prompted by reports of loss of displayed airspeed.

The FAA has adopted a new airworthiness directive, effective March 26, for certain serial number Pratt & Whitney Canada PW206B/B2/C and PW207C/D/D1/D2/E turboshaft engines. The AD was prompted by the discovery that certain power turbine (PT) disks were made to heat codes that may not achieve the maximum in-service life. This AD requires re-identification of the PT disk to a part number (P/N) with a lower life limit.

Since when is an Emergency AD used to ground an aircraft fleet, as it has been in the case of the Boeing 787 Dreamliner? First off, let me be clear that if anything good can be said of the Boeing Dreamliner nightmare it’s that no one had to die before the FAA would take definitive action to ground the 787 until its battery fire problems could be investigated properly.

Text of the statement released by the FAA late today.

The FAA is revising an earlier proposed airworthiness directive for the Eurocopter BO105A/C/LS/LS A-3 and 105S. The earlier AD proposed inspecting for debonding of the erosion protective shell (abrasion strip) on the leading edge of each main rotor blade. This SNPRM proposes to revise those inspection requirements by identifying specific dates of replacement of the applicable parts and identifying a specific inspection method to discover debonding of an abrasion strip.

Gulfstream Aerospace technicians were responsible for uncovering a preflight systems test malfunction that led to last week’s FAA Airworthiness Directive on all 260 G350/450s. The December 12 directive–2012-NM-219-AD–took effect December 17 and addresses the flap/stabilizer electronic control unit cockpit crewmembers normally test before the first flight of the day.
