document: Authorities questioned the badly injured pilot of a crashed Boeing 737 Wednesday , but revealed no clues as to why the jet 's undamaged right engine was shut down well before the crash while the other engine burned . The Civil Aviation Authority , meanwhile , ordered increased inspections on 37 airplanes with CFM56 engines , the type on the Midland Airways jet that crashed Sunday . Investigators said much more work was needed to pinpoint the cause of the crash , which killed 44 people and injured 82 . The government also ordered immediate checks of engine monitoring systems on similar aircraft to verify that they correctly indicate right and left , prompting speculation that a malfunctioning alarm system could have misled the flight crew . Freddie Yetman , technical secretary of the British Airline Pilots Association , said this showed that investigators `` must have some suspicion of these circuits . '' In the United States , the Federal Aviation Administration ordered inspections of 300 Boeing 737s for possible cross-wiring of engine warning systems . U.S. media reported that the crew of the jet shut down the wrong engine , and Britain 's tabloid newspapers drew similar conclusions in banner headlines . `` Error on the Flight Deck , '' the Today newspaper said . `` Fatal Error '' said the Daily Star . `` Pilot Shut Off the Wrong Engine '' said the Sun . The Transport Department said that `` evidence obtained early in the investigation '' indicated both of the plane 's engines `` might have suffered a related failure '' and that possibility was still being examined . The statement from the department 's Air Accidents Investigation Branch also confirmed that the airplane 's left engine caught fire and the right engine was shut down , and that pilot Kevin Hunt had told ground control the fire was in the right engine . The reasons for shutting down the engine `` are not yet clear and are still under investigation , '' it said . The jet , en route from London to Belfast with 126 people aboard , plunged into an embankment a half-mile short of the runway at East Midlands Airport in central England as it was trying to make an emergency landing Sunday night . Hunt , whose back and legs were broken in the crash , was interviewed for 45 minutes at the intensive care unit of Leicester Royal Infirmary , said the hospital 's deputy general manager Carol Henshall . Mrs. Henshall said some of the `` wilder headlines '' had been kept from Hunt , but friends and colleagues had told him of the news reports . In the United States , NBC News quoted unidentified U.S. government sources as saying `` the plane 's flight recorders , which monitor engine performance and the pilots ' conversations , indicate the crew shut down the wrong engine . The trouble was in one _ they shut down the other . '' But the network said investigators had yet to detemine whether faulty instruments contributed to the crash . The Washington Post , quoting unidentified accident investigators , said the crew believed they were making a routine , one-engine emergency landing , and apparently thought they had solved the problem when they shut down an engine . Spokesmen for both the FAA and the National Transportation Board said they knew of no information reaching U.S. officials about the flight recorders ' contents . The airplane 's two `` black boxes , '' the cockpit voice recorder and digital flight data recorder , are being examined at the government 's laboratory in Farnborough , outside London . According to court documents and federal officials in America , the FBI is investigating a General Electric Co. admission that test records may have been falsified at a factory which made parts for the CFM56 engine that failed here . The Seattle factory also made a check and flow valve for the F404 engine aboard the Navy 's FA-18 fighter , GE spokesman Richard Kennedy said Wednesday . A letter from a GE attorney last year said test records may have been falsified for the fighter plane valves . The timer valve made by GE for the CFM56 engine could not have caused the turbine to fail even if the valve malfunctioned , Kennedy said . The plane took off at 7:52 p.m. Sunday . Government sources , speaking on condition of anonymity , said Hunt reported at 8:06 p.m. that `` I have an engine on fire . '' Then , at 8:14 p.m. , the sources said he told traffic control : `` I am shutting down the starboard -LRB- right -RRB- engine . '' The plane crashed 12 minutes later at 8:26 p.m. . The Civil Aviation Authority said that on the advice of investigators , it was issuing new instructions for the inspection and monitoring of Boeing 737-300 , Boeing 737-400 and Airbus A320 airplanes , all of which use the CFM56 engine . The engines are made jointly by U.S.-based GE and a French company , SNECMA . Boeing Commercial Airplanes spokesman Craig Martin said in Seattle of the FAA 's inspection order , `` We certainly believe it 's a prudent measure to go out and check to make sure there 's nothing wrong with the fleet . But certainly this precautionary measure does not imply there has been any cause identified -LRB- for the crash . -RRB- ''
