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.
The FAA last week proposed a $547,500 civil penalty against Hawaiian Airlines for operating a Boeing 767-300 “more than 5,000 times” when the aircraft was not in compliance with a July 2000 airworthiness directive (AD). The AD required inspections of certain engine thrust reverser components to prevent a portion of the device from separating in flight and causing a rapid decompression of the aircraft. It also mandated initial and repetitive inspections of the components to detect damage and wear, and to take corrective actions if necessary.
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier Challenger 300s. The AD was prompted by multiple reports of erratic electrical status indications on the pushbutton annunciators and the engine indication and crew alerting system (EICAS). Some of those reported incidents involved a momentary loss of electrical power and loss of flight displays.
The FAA proposed an airworthiness directive last week on the autothrottle computers installed on the Boeing 737-600/700/700C/800/900 to correct a glitch that in 2009 allowed a faulty radar altimeter aboard a Turkish Airlines 737 to tell the autothrottles to revert to idle thrust while the aircraft was still on final approach. The aircraft crashed in Amsterdam, killing nine people and injuring 117.
Embraer has selected Cleveland, Ohio-based Constant Aviation to become a Legacy 450 and 500 authorized service center. The MRO will be able to provide maintenance, avionics services, modifications and composite repairs, and it will also be able to address Airworthiness Directives and Service Bulletins on both aircraft. The announcement builds on a 15-year partnership that includes authorized service center status on the Legacy 600/650 and Phenom 100/300. The company’s Birmingham, Ala. operation also holds service center status on the Phenom 100/300.
