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.
The Gulfstream G280 is the latest addition to Jet Support Services’ Tip-to-Tail hourly-cost maintenance program. The program, which covers the engines, airframe and APU, offers G280 operators a single-source maintenance solution.
The FAA is proposing to adopt a new airworthiness directive (AD) for certain Pratt & Whitney Canada PT6A engines. The proposed AD was prompted by in-service events involving the perforation of engine cases as a result of the liberation of power-turbine blades and the fracture/displacement of the power-turbine containment ring.
The Eurocopter EC135 light twin helicopter is facing more trouble after the EASA issued an emergency airworthiness directive on December 19 referring to a manufacturer alert service bulletin that requires a one-time check of fuel probes and, possibly, cleaning and replacement. The issue, discovered by Bond Air Services, appears to be that the probes are indicating a fuel level higher than actual. Investigations showed that the incorrect signals that the probes transmit to the indicator may also inhibit the amber “fuel caution” light.
Incorrect data in aviation records is serious in the extreme. Aviation depends on data entry to record everything from student pilot training to air carrier compliance with airworthiness directives to scores of information on every aspect of defeating gravity safely. For that reason, air safety relies in large part on records, the accuracy of which is critical.
The FAA has issued an airworthiness directive (AD)–2013-22-19–for the Gulfstream V and GV-SP to address unrelated problems with fuel boost pumps.
The FAA is reminding aircraft operators through a special airworthiness information bulletin– NOTC5068, issued November 22–about a few idiosyncrasies to keep in mind when updating aircraft navigational databases. “The cyclical updates may exclude certain navigation data, including approach procedures, which makes this information unavailable for selection on the aircraft flight management system or navigation equipment,” warned the bulletin.
The FAA has issued a final rule to adopt a new Airworthiness Directive (AD) for the sliding doors on the Eurocopter AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350C, AS350D, AS350D1, AS355E, AS355F, AS355F1, AS355F2, AS355N and AS355NP. The AD does not apply to aircraft that have modification AL 4262. The AD, which requires removing specified nuts and washers from the lower ball-joint bolt, was prompted by a report of a sliding door detaching from the helicopter in flight.
