A JAT Convair 340 aircraft, acting as an instructor, departed Vienna at 18:37 for Munich. The pilot and co-pilot shared command, and the aircraft descended to 3500 feet. A minute later, the crew reported leaving 3000 feet, prompting GCA to instruct a pull-up. GCA did not receive a response, leading to rapid descent. The aircraft struck the ground on the left wing and left undercarriage, approximately 6.85 km from the runway threshold and 200 meters right of the glide path. The aircraft came to rest with both wings detached after a ground side of 400 meters.A JAT Convair 340 aircraft, acting as an instructor, departed Vienna at 18:37 for Munich.

Description

The JAT Convair 340 departed Vienna at 18:37 for a flight to Munich. The captain was acting as an instructor on this flight in the right-hand seat; the co-pilot acted as pilot-in-command. At 20:33 the flight passed the Munich NDB at 20:33 at FL120. The aircraft then started the descent. After reaching 3500 feet at 20:58 the flight was cleared to 3000 feet msl (which is 1268 feet agl), which altitude was to be maintained. One minute later the crew reported leaving 3000 feet. GCA then told the crew to pull up and maintain 3000 feet. GCA did not receive an answer. The Convair 340 descended fast and struck the ground left wing and left undercarriage first, at a point 6,85km from the runway threshold and 200 m right of the glide path. The aircraft came to rest with both wings detached after a ground side of 400 m. Weather at the time of the crash was: wind 210-240 deg/3-5 kts; visibility 1-1,5 nm possibly only 0,7-1,0nm; moderate snowfall; cloud base 600-800 feet; ground temperature -1deg C.

Primary Cause

Rapid descent and ground contact due to a potential loss of control during the descent.Rapid descent and ground contact due to a potential loss of control during the descent.
