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.
The FAA has issued a supplemental notice of proposed rulemaking revising an earlier proposed airworthiness directive for Cessna 525 Citations equipped with certain part number air conditioning compressor motors. The NPRM proposed to require inspection of the number of hours on the A/C compressor hour meter, inspection of the logbook and replacement of the brushes on specified compressor motors or deactivation of the A/C system until replacement of the brushes.
The FAA on Wednesday issued an airworthiness directive (AD) requiring inspection of Boeing 787-8 engine fuel feed manifold couplings after receiving reports of fuel leaks on two in-service aircraft.
Operations of the latest version of Eurocopter’s ubiquitous light single, the AS350B3e Ecureuil/AStar, have been affected by an emergency service bulletin and accompanying emergency airworthiness directive (AD).
Under the restrictions, the helicopter’s true airspeed is limited to 100 knots to reduce dynamic loads on the tail rotor. In addition, repetitive inspections must be conducted, with maximum intervals of three flight hours, on the laminated half-bearings.
