Bek Air plane with 100 on board crashes just after takeoff in Kazakhstan

You bang the tail twice on takeoff, either the speeds are wrong or aerodynamically....the thing won’t fly ie; contaminated wings. Hard wing aircraft like the F28/100, DC-9-10 are not happy campers with surface contamination.
"Those responsible will face tough punishment in accordance with the law," Kazakh President Kassym-Jomart Tokayev tweeted
What a jerk, I hope he won’t disrupt investigations with this.

I saw that too. Nothing like assuming a crime took place before any facts are known.
Fokker has a very sensitive wing to Contamination or if the flap/slat settings right?
Let the investigstors determine.
RIP to families..

Ever seen a Fokker with “slats”?
Is the airline maker still in business? They would probably supply the most accurate investigation of the accident. I wouldn't trust anything from the Kazakhstan government. Banging the tail a couple of times would definitely effect aerodynamics. Wonder if the airport has any camera's? Lots of unknowns
I believe Fokker went into bankruptcy in March 1996. Tail strikes are not uncommon especially when the aircraft is over rotated at Vr on take off. Most hard leading edge aircraft like the Fokker family, some DC-9-10 models with even a little surface contamination will inhibit the wings performance to the point where on rotation, lift may be compromised and the aircraft may liftoff in ground effect but after reaching 50-80’ of altitude the aircraft wing stalls. The other issue is if the wing is contaminated, the tail may also be compromised. An aircraft with a high tail (T-tail) may not show signs of contamination from ground level so as the speed builds on takeoff and the pilot rotates, nothing happens but when the pilot pulls the controls further back at a higher speed the tail bites and pops the nose off the ground very quickly, so quickly that before the pilot can push the control the tail hits the ground. Even the G4 that ran off the runway some time ago (control lock engaged), if only the pilot moved the controls even a little and discovered that nothing was happening, he could have aborted. Much easier to detect a control lock than a contaminated tail plane causing reduced performance! Still too early in the investigation, however!
According to Wikipedia: F100 takeoff run at full gross needs 5,319 feet of runway; Almaty’s runways are over 14,000 feet. Even allowing for 2,400 foot field elevation, you’d think there would be enough left to abort and stop on the runway after encountering problems at Vr. Just speculating, the investigation will (hopefully) tell all.
You would think so? I’ve flown out of Almaty. Problem is “if” it was wing/tail contamination that would greatly increase the take off roll and the speed would have been well beyond v2 so the thinking may have been it will get airborne eventually. It was reported that the a/c was deiced but with what, type 1, type 2 or type 4?
