A TransAsia ATR 72 crashed yesterday on take off from downtown airport.
Investigators will look at the following:
- Because the reported Mayday call indicated engine flameout, there will be initial focus on the engines and with it, anything that contributes to flameouts, such as fuel contamination, bird or other foreign object ingestion, and mechanical issues;
- They will look at why the airplane didn’t climb out under power of one engine, as airplanes are designed to do;
- Did only one engine flame out or did both;
- What caused the airplane to drop off dramatically on one wing to a perpendicular position as it crossed the highway–did the plane fall off on one wing due to flight conditions or did the pilot, believing he was going to lose the plane, bank sharply in a desperate attempt to avoid crashing into the city;
- Pilot actions in handling the flameout and subsequent actions in flying the airplane;
- Did the pilots deliberately head for the river to avoid crashing into buildings;
The mechanical history of the airplane; and
- The history of the pilots.
Recovery of the flight data recorder and cockpit voice recorder should provide information quickly to answer many of the questions above but the full investigation typically takes a year or more.
