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.
The FAA has issued an NPRM for a new airworthiness directive for the Embraer Phenom 300 that would supersede AD 2013-22-20. The proposed AD describes the unsafe condition as cracks beyond acceptable limits in the carbon discs of the left and right brake assemblies.
The FAA has issued an NPRM to supersede airworthiness directive 2013-21-01, which currently applies to the Airbus Helicopters AS350B/BA/B1/B2/B3/C/D/D1 and AS355E/F/F1/F2/N/NP. The current AD requires certain inspections of each tail-rotor pitch horn assembly for a crack and, if there is a crack, replacing the pitch horn with an airworthy pitch horn before further flight. It also requires a one-time visual inspection for pitch horns above certain hours time-in-service (TIS).
The FAA is adopting an airworthiness directive for all Rolls-Royce Deutschland BR700-725A1-12 turbofans. The AD requires removal of affected fuel metering units on the BR700-725A1-12. This AD was prompted by reports of wear on the receptors of the double-ended unions in the FMU housing on BR700-725A1-12s causing fuel leakage. The AD is intended to prevent failure of the FMU, which could lead to damage in one or more engines and damage to the airplane. The AD becomes effective July 17.
The FAA proposes to adopt a new airworthiness directive for certain Rockwell Collins TDR-94 and TDR-94D mode-S transponders. The AD was prompted by instances of the transponders not properly responding to mode-S only all-call interrogations when the airplane transitioned from a ground to airborne state.
Cessna announced that its company-owned service centers in Paris; Doncaster, UK; and Düsseldorf, Germany, are authorized as continuing airworthiness management organizations (Camo) by the European Aviation Safety Agency (EASA). Camo approval enables these service centers to issue and extend airworthiness review certificates to EASA-registered aircraft.
