On May 4, 1972, a Yakovlev Jak-40 crashed on the inner-Soviet scheduled flight Aeroflot flight W-608 from Irkutsk to Bratsk , killing all 18 occupants.
Plane and crew
The plane was a two-year-old Yakovlev Yak-40 with the air vehicle registration CCCP-87778, the three turbofan engines of the type Ivchenko 25 AI was used was equipped and from 30 October 1970th
The crew consisted of a flight captain , a first officer , a flight engineer and a trainee.
course
The Jak-40 took off from Irkutsk at 10:29 p.m. local time and rose to a cruising altitude of 6000 m . When approaching Bratsk, the pilots made radio contact with the air traffic controller there and reported at 23:31 that they were ready to land. Despite several inquiries, the air traffic controller had not received any current weather data and, despite the visible, rapid deterioration in the weather, was forced to provide the data for 11:15 p.m. ( visibility of 50 km, no precipitation). He then gave landing permits for the pilots, which they confirmed. Shortly afterwards, they were surprised by the bad weather when they flew into a wet blizzard with visibility of 1000 m and wind speeds of 10 to 14 m / s (36 to 50 km / h); this was far below the weather minimums that the flight captain had previously set. The aircraft lost altitude, brushed a few pine trees, hit 1250 m from the runway threshold at 23:34 and burned out.
root cause
A gust of wind that hit the aircraft was found to be the cause of the loss of altitude at a low altitude . Since the thrust reverser was found in the open position, the possibility was not ruled out that it was accidentally activated during altitude loss, which would have made the situation worse.
