Concerning the Lear 55 that crashed last night in Philadelphia. One possible cause of this crash and the one that I believe is the most likely, is that the aircraft suffered a catastrophic engine failure, most likely the left engine, that exploded and severed the cables that control the rudder, ailerons, horizontal stabilizer and perhaps the throttle control cables to the engines.
This would explain the total loss of control and the unexpected turn back to the east when the crew’s takeoff clearance was to make a right turn to a heading of 290 degrees from RWY 24. With the throttle cables severed the right engine would have been producing full take off power and the failed left engine producing little to no thrust.
Without being able to control the turn radius of the aircraft the thrust of the right engine would have forced the aircraft into a left turn which would explain the reason why the jet ended up to the east of it’s intended flight path.
In a report I saw this morning and the first time I’ve heard any of the audio associated with this video, you can hear that a “engine” is producing power and it sounds like it is a lot of power, which would also explain the EXTREMELY rapid descent this aircraft made from only 1300 feet above the ground on take off.
May God Bless these people.
