The FAA has issued a notice of proposed rulemaking to adopt a new airworthiness directive for Airbus Helicopters AS355Es, AS355Fs, AS355F1s and AS355F2s with a Fueltron flowmeter installed. This AD would require removing each flowmeter, replacing the fuel system hoses and disabling the electrical connections for the flowmeter installation. It is prompted by a report of particle contamination creating an obstruction in a flowmeter, resulting in an uncontrolled flameout of the engine.
FAA airworthiness directive AD 2014-16-21, effective October 2, will require operators of Dassault Falcon 7X trijets to replace certain pintle pins in the left- and right-hand main landing gear. The agency found that some pintle pins in the Messier-Bugatti-Dowty landing gear had been incorrectly corrosion-protected, which could cause them to shear under normal load and lead to collapse during takeoff or landing.
The FAA has issued a superseding Airworthiness Directive (AD) for the Bombardier Challenger CL-600-1A11 (CL-600), CL-600-2A12 (CL-601), and CL-600-2B16 (CL-601-3A, CL-601-3R and CL-604). It requires operators to assign serial numbers or part numbers to certain landing-gear parts; establish the number of landings on the parts, if necessary; and revise the Airworthiness Limitations Section of the Instructions for Continued Airworthiness (ICA).
The FAA is adopting a new airworthiness directive for certain Embraer Phenom 100s. It requires inspection and replacement as necessary of the barrel nuts at the horizontal stabilizer to vertical stabilizer attachment joint.
Traxxall Technologies announced a new aircraft maintenance tracking service for business aviation yesterday. The new purpose-built, Web-based system is claimed to improve business aircraft operators’ ability to track maintenance on their aircraft, ensure regulatory compliance and protect aircraft residual values. It is available for all fixed- and rotary-wing business aircraft.
The FAA is adopting a new airworthiness directive for the Bombardier CL-600-1A11. It requires revising the airplane flight manual to prohibit thrust reverser operation. The AD also calls for repetitive detailed inspections of both engine thrust reversers for cracks and modifying them if necessary. Modifying the thrust reversers is also an optional terminating action for the repetitive inspections.
The FAA has issued a notice of proposed rulemaking on an airworthiness directive (AD) for the Dassault Falcon 50 slat system. It is prompted by an intermittent indication of slat activity caused by chafing of the electrical wiring.
The FAA is issuing an Airworthiness Directive for Airbus Helicopters (previously Eurocopter France) EC130B4 and EC130T2. The AD requires repetitive inspection of the fenestron-to-tailboom junction frame for a crack. This AD is prompted by reports of a crack propagating through the junction frame on two EC130B4 helicopters. These actions are intended to detect a crack and to prevent failure of the junction frame, which could result in loss of the fenestron and subsequent loss of control of the helicopter.
The FAA is publishing a new Airworthiness Directive (AD) for certain AgustaWestland AB139 and AW139 helicopters. It requires repetitive inspection of the main rotor (M/R) rotating scissors for play of the lower half scissor spherical bearing and removing the bearing if there is play beyond allowable limits. It also requires removing all affected bearings. This AD is prompted by reports of certain bearings dislodging from certain M/R rotating scissors.
The FAA is proposing to adopt a new airworthiness directive for certain Sikorsky Model S-92A helicopters requiring the installation of a main gearbox (MGB) failed pump sensor and vacuum switch wiring, installing an MGB oil auto bypass system, activating aircraft management system (AMS) 7.1 software to show a new visual warning and installing updated enhanced ground proximity warning system software that includes an aural annunciation of a complete oil pressure loss condition.
