Bangalore: The National Transportation Safety Board (NTSB), the independent safety investigator of the US, has issued two urgent safety recommendations on General Electric GEnx engines, which power the latest generation of Boeing aircraft: Both the 787 Dreamliners and the Boeing 747-8s.
The GEnx-1B engines power the 787 Dreamliners that are the newest addition to Air India’s fleet. Among other users of the engine are Japan Airlines (JAL) and Ethiopian Airlines, with Qatar Airways set to join soon. The two other 787 operators, All Nippon Airways (ANA) and LAN Chile, have their aircraft powered by the Rolls Royce Trent 1000 engines.
The Dreamliner’s first commercial flight is scheduled to be on September 19. The GEnx-2B engines power the Boeing 747-8i of Lufthansa and the 747-8F freighters of many carriers.
The investigation of the GEnx engines began with the July 28 engine failure incident at Charleston, US, involving a Boeing 787 Dreamliner destined for Air India. Initial investigations had suggested a fracture failure of the fan midshaft (FMS). While that investigation is on-going, on August 31, NTSB had found similar signs in another GEnx-1B fitted on a yet-to-fly Boeing 787. The fan midshaft was removed from that engine for further inspection and examination.
