These are the words of the captain of TransAsia Airways Flight GE235, eight seconds before the plane clipped a bridge and plunged into a Taiwanese river mere minutes after takeoff.The latest report by Taiwan's Aviation Safety Council into the February crash confirms that the captain of the ATR 72-600 turboprop aircraft mistakenly switched off the plane's working engine after the other lost power.The investigators will come out with what causing the crash by eliminating and combining factors such as mechanical failure, bad weather, hijacking, or pilot error. From the flight data recorder,suggest that,engine no 1 which is at the left side still functioning.ATR 72 capable to generate lift although with an engine.By the right configuration such as feathering (adjusting the degree of propeller blade to increase thrust and decrease drag force) the propeller could sustain the plane thrust and lift sufficient to pilot the plane climb gaining safety altitude and make an emergency landing to the airport.Air crash did not occurs with a problem, it occurs when multiple occasion of problem taking part. As a result, the pilot flying the aircraft became confused regarding the identification and nature of the propulsion system malfunction. The turboprop engines attached to the plane have unique character than other jet engines.
The preliminary report issued by Taiwan's Aviation Safety Council. Two minutes after takeoff, the pilots reported an engine Flight 235 was the second fatal accident involving a TransAsia Airways ATR aircraft within seven months: At the time of the accident, no adverse weather phenomena were observed.
once the plane had climbed 1,200 feet, a master warning sounded, and a display showed that there had been an engine flameout, or power failure, in engine 2 (the right side engine).For ATR 72 flying with an engine not a problem.
During the initial stages of the take-off roll the flight crew did not reject the take off when the automatic take off power control system ARM pushbutton did not light, and TransAsia did not have a clear requirement to do so.
The preliminary report suggest that from the cockpit voice recorder (CVR), there was shocking phrase came out from the pilot. The autofeathering was caused by compromised soldering joints in the auto feather unit. But if so, why was the plane given permission to land? When the pilot switched off the functioning engine, with insufficient thrust generates the plane entering aerodynamic stall, which is no lift generates on the wings plus with the drag force built up from static unfeathered propeller, these characters combined to plunge the plane according to gravity rules,According to records provided to the investigators by TransAsia, the captain had previously served in the Taiwan Air Force as a pilot.He worked for another airline briefly after leaving the Air Force, before joining TransAsia in August 2010.He served as a first officer in the ATR 72-500 fleet, before completing upgrade training and being promoted to captain in August 2014. In November that year, he completed further training to transfer to the ATR 72-600 fleet as captain.TransAsia training records show that during his upgrade training in April 2014, he failed a simulator check, performing unsatisfactorily on the abnormal engine start section, among others.Among the areas of concern was that he demonstrated insufficient knowledge of dealing with engine flameout at takeoff, the instructor noted.The pilot was given another session and qualified as captain after passing the simulator check.In July 2014, 48 people were killed when a TransAsia ATR 72-500 crashed when approaching to land in bad weather on Penghu Island, Taiwan. The study of two black boxes suggest that the ability of the pilot to handle the emergency procedures questioned. In procedures switch off the flame out engine will give the chance for the pilot focusing for the functioning engine.In this case the left engine. Thirty-one passengers were The flight crew consisted of two pilots, both ranked as captains; the captain was Liao Chien-tsung, 42, with a total of 4,914 flight hours (including 3,401 hours on the ATR 72) and the co-pilot was Liu Tze-chung, 45, with a total of 6,922 flight hours, including 5,314 hours on the ATR 72.Taipei police and fire departments received dozens of calls from eyewitnesses almost immediately after the crash.
