Circumstances:
Following an uneventful flight from Petropavlovsk-Kamchatsky, the crew started the descent to Palana Airport Runway 11 from the south. In marginal weather conditions, the twin engine aircraft descended too low, impacted trees and crashed in a wooded area located on Mt Pyatibratka. The wreckage was found at a height of 216 meters some 10 km south of the airport. Both pilots and 8 passengers were killed while four other passengers were seriously injured. Thea aircraft was destroyed by impact forces.
Probable cause:
The fatal accident with An-28 RA-28715 aircraft was caused by violation of specified approach pattern in Palan Airport resulted in outbound track and premature descending up to unauthorized low altitude performing flight in mountainous terrain in weather conditions excluding sustained visual reference with ground references resulted in aircraft collision with mountain slope, its destruction and crew and passengers fatality. Alcohol was detected in blood of both crew members.
Contributing factors were:
- Low level of discipline of personnel in Petropavlovsk-Kamchatsky Air Enterprise and inadequate flight methodical work in enterprises in a part of crew preflight training and approach patterns monitoring.
- Crew inaction when the radio altimeter altitude alert was actuated.
- Ground Proximity Warning System at An-28 aircraft could probably prevent the accident.
