Information is starting to come forward on the Turkish Air crash. Again, I’m very hesitant to comment on an accident before the facts are released. Some of my readers have asked my opinion so I will address what facts are known. There are some striking similarities between it and the Colgan Air crash in Buffalo. Put icing aside, in my opinion icing was a distracter; pertinent only because it raised the stall speed. And the crew compensated for the increase by raising speeds, activating a switch that set higher speeds for approach.
So, what are the similarities? First both were on a normal approach; both had normal communications with approach control and switched to tower for landing clearance with no apparent problems. At that point, both experienced a pitch up and what was described as “turbulence” by the survivors of Turkish Air (Colgan went through severe gyrations). One survivor claimed he heard the power come up (like the Colgan flight) before it impacted. However there is conflicting information that mentions the possibility of engine failure.
Investigators have admitted the aircraft “lost speed” and “came straight out of the sky” it is probable that the turbulence and pitch up was a wing stall. The cause will come out as the flight data recorders are analyzed. These accidents are tragic, even more so if they could have been prevented.
