Accident Details
The aircraft was conducting a cargo flight from Arsenyev to Bukhta Provideniya with intermediate stops at Khabarovsk and Chaibukha. It carried 15 passengers, 6 crew members, and a load of six tons of fruits and vegetables.
Sequence of Events
During the takeoff roll from Chaibukha Airport, a misunderstanding occurred among the crew. The pilot-in-command failed to initiate rotation and takeoff. The aircraft continued rolling for approximately 2,250 meters, overran the runway, went through a fence, and came to rest in a swampy area.
Casualties and Damage
Four crew members and four passengers were killed, while 13 other occupants sustained injuries. The aircraft was destroyed.
Probable Cause
Official findings attributed the accident to poor flight preparation and wrong takeoff configuration by the crew. Contributing factors included: rushed takeoff, failure to follow pre-takeoff checklist, inappropriate elevator angle during takeoff, aircraft weight above maximum takeoff weight (MTOW), insufficient crew rest time, fatigue, alcohol detected in the captain's blood, poor crew coordination, crew misunderstanding, pilot-in-command's failure to initiate rotation, and failure to abort the takeoff procedure once it was compromised.
