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.
A new airworthiness directive (AD) for the Learjet 45 stems from a report of two cases of premature corrosion on the structural support flange for the engine thrust reverser. The AD requires inspecting for any corrosion, and damage to the sealant; installing sealants and gaskets; and related investigative and corrective action as necessary.
GE Aviation is preparing to begin flight tests of its new Leap-1C and Passport engines featuring nacelles developed for them by the group’s Nexcelle joint venture with Safran subsidiary Aircelle. Last month, Nexcelle delivered the first full new-generation nacelles for both programs. They are due to fly soon on the engine maker’s Boeing 787 testbed. The Leap-1C is to power Comac’s C919 narrowbody airliner, while the Passport has been selected for Bombardier’s Global 7000 and 8000 business jets.
Hawker Pacific Aerospace has opened its new 12,000-sq-ft airframe-related component (ARC) shop in Fort Lauderdale, Fla. The move broadens the landing gear specialist’s expertise to include services for thrust reversers. The facility, which has already received its first five thrust reverser units, serves as the hub of thrust reverser services for Lufthansa Technik’s customers within the Americas.
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.
Dallas Aeronautical Services, located 20 miles south of Dallas Love Field, is a highly specialized maintenance, repair and overhaul facility focused on a niche market. According to Mike Manning, the company’s vice president, DAS specializes in component repair.
“We do a significant amount of spares and rotables work for OEMs; however, we also work with both maintenance providers and owner/operators. Our specialization is working with clients who need a high quality but fast solution to their component repair requirements,” he told AIN.
A switch from composite to titanium for the inner walls of the thrust reversers on the Boeing 737 Max has allowed designers to increase the fan diameter in the airplane’s CFM International Leap-1B turbofans without a proportional increase in the size of the nacelle. The relatively minimal growth of the nacelle means Boeing could keep its original plans for coping with the small amount of ground clearance margin available while optimizing thrust levels, explained 737 Max program vice president and general manager Keith Leverkuhn.
Russian accident investigators appear to be focusing on possible failures in the thrust reversers and/or brakes of a Red Wings Airlines Tupolev Tu-204 airliner that crashed into a Moscow highway after overshooting a runway at Vnukovo Airport on December 29. The aircraft was on a ferry flight from Pardubice in the Czech Republic with no passengers. Five of the eight crewmembers on board were killed, including the captain, first officer, flight engineer and two flight attendants.
Safran USA (Booth No. 2579) is flexing some considerable muscle here at the convention, showing a diverse role in the business aircraft market that stretches from nose to tail and wingtip to wingtip. Among the aviation products available from this global conglomerate are turbofan engines, nacelles, thrust reversers, landing gear, wheels and brakes, auxiliary power units, avionics, navigation systems, flight controls and wiring.
The search for answers continues into what caused the mid-afternoon landing overrun accident of a Gulfstream GIV at Le Castellet Airport (LFMQ), in France, on July 13.
