The Fokker 100 aircraft, heading for the capital, Nur-Sultan, on a pre-dawn flight on Friday, "lost altitude during takeoff and broke through a concrete fence" before hitting a two-storey building, Kazakhstan's Civil Aviation Committee said in a statement.

The Almaty healthcare department had earlier said that at least 15 people died. This figure was scaled down to 14 by government officials. The higher figure was the result of confusion on the ground, a spokeswoman for the department said.

"The plane was flying with a tilt. Everything was like in a movie: Screaming, shouting, people crying," she said. Images posted on social media showed several rescue personnel digging through the wreckage of the Bek Air aircraft. A special commission is investigating the circumstances leading to the deadly incident, airport officials said. The crash site in Almerek village - just beyond the end of the runway - has been cordoned off. In a statement published on social media, President Kassym-Jomart Tokayev expressed his condolences to the friends and families of those killed in the crash. "All those injured will be rendered assistance. All those responsible will carry severe punishment in accordance with the law," Kazinform news agency quoted the president as saying in the Kazakh language. The company manufacturing the aircraft went bankrupt in 1996 and the production of the Fokker 100 stopped the following year. All Bek Air and Fokker 100 flights in Kazakhstan have been suspended pending the investigation of the crash, the country's authorities said.

st27 Posted December 27, 2019 Share Posted December 27, 2019 Sound like YHD?? Still early in investigation but..... Quote Aviation expert Geoffrey Thomas told DW the report of shuddering could have been a sign of an ice build-up on the wings, while the large bang could be an indication of an engine failure. Authorities have assured reporters that the plane was de-iced before takeoff, however, survivor Nazaraliyev recalled that the wings of the plane were covered in ice, and passengers who used emergency exits over the wings were slipping and falling down. https://www.dw.com/en/kazakhstan-plane-with-nearly-100-people-on-board-crashes/a-51804609 Link to comment Share on other sites More sharing options...
Don Hudson Posted December 27, 2019 Share Posted December 27, 2019 One difference - Dryden was a "hard wing", the 100 has LE devices. But yes, this has a number of indications of contaminated wing(s). Link to comment Share on other sites More sharing options...
J.O. Posted December 28, 2019 Share Posted December 28, 2019 Could also be a problem with flaps setting. Wouldn’t be the first time. Link to comment Share on other sites More sharing options...
Kip Powick Posted December 28, 2019 Share Posted December 28, 2019 More speculation....compressor stall, (loud bang), and ice on the wings... Link to comment Share on other sites More sharing options...
st27 Posted December 28, 2019 Share Posted December 28, 2019 Hi Don...small point, but I have yet to find a reference or image of the f100 with LEDs...I always thought the wing was “hard”. My understanding was that the LEDs made a big difference in t/o performance and that the lack of made a clean wing all the more critical. Link to comment Share on other sites More sharing options...

Bek Air Fokker crash inquiry set to analyse freezing Almaty conditions By David Kaminski-Morrow27 December 2019 Save article Investigators probing the fatal Bek Air Fokker 100 accident at Almaty will be seeking to establish whether freezing conditions contributed to the aircraft’s failure to climb away during take-off. Mist was present at the time, according to Almaty airport meteorological data, with the air temperature of minus 12C close to the dew point of minus 13C. The commission of inquiry into the 27 December accident has yet to determine the take-off configuration of the aircraft and, crucially, whether it had required de-icing before the early morning flight. Source: Kazakhstan ministry of emergency situations Temperatures at the time of the Bek Air accident were far below freezing Icing has previously been implicated in at least two fatal Fokker 100 take-off accidents in freezing conditions – including the loss of a Palair aircraft at Skopje in March 1993 and that of an Air France Regional jet at Pau in January 2007. Neither crew detected the presence of ice contamination on the wings and neither requested that the aircraft be de-iced before departure. Both the Palair and Air France jets had conducted take-off with an 8° flap setting. The flap setting on the Bek Air aircraft has not yet been disclosed. The inquiry into the Palair accident stated that the lifting capability of the wing had been impaired above 10° angle-of-attack, whereas it would not normally have stalled below 16.5° with 8° of flap. Its analysis drew attention to various issues including the risks of wing contamination arising from cold-soaking of fuel. The Palair aircraft oscillated before banking steeply to the right, its wing striking the ground before the jet broke up, resulting in 83 fatalities among the 97 occupants. Source: BEA Investigators determined that this Air France Fokker 100 was not de-iced before take-off Although the Air France Fokker 100 also experienced severe oscillations as it lifted off, it stayed relatively intact as it contacted the ground. The only fatality was the driver of a truck which was hit by the jet as it crossed a road. French investigation authority BEA, which probed the Air France accident, highlighted two other icing-related take-off accidents which occurred to Air Ontario and USAir Fokker F28 jets, the predecessor to the Fokker 100 and Fokker 70. Concern over the vulnerability of Fokker 100s to icing conditions led the European Union Aviation Safety Agency, in early 2009, to mandate the installation of on-ground wing leading-edge heating systems on the type. EASA stated in its directive that some aircraft had already been fitted with such a system following the Palair accident. Among the aircraft delivered with the system installed, EASA’s directive noted, was MSN11496 – the airframe involved in the Bek Air accident at Almaty. The status of the system on the aircraft has not been clarified. Topics Asia Pacific Safety Link to comment Share on other sites More sharing options...
Don Hudson Posted December 29, 2019 Share Posted December 29, 2019 hi st27: Thanks for the correction - the Fokker 100 does NOT have leading edge devices. I didn't read carefully enough - here's what I saw in Wiki: "... has new flaps and larger ailerons, and extended leading and trailing edges improve aerodynamics and increase the wing chord. " , and I read "leading edge" then jumped to the conclusion that that was the high-lift device. Sigh. So, "hard wing", & thank you! Link to comment Share on other sites More sharing options...
