Circumstances:
The airplane departed Okha on a flight to Khabarovsk with intermediate stops in Nikolayevsk-on-Amur and Nijnetambovskoye. While descending to Nijnetambovskoye, the pilot encountered marginal weather conditions. Because the visibility was limited, he reduced his altitude to minimum. On final approach, at a height of 50 metres, the right wing failed and detached. The airplane nosed down and crashed in a pasture. All 16 occupants were killed.
Probable cause:
Failure of the right wing on approach because of poor repairs of the four supporting beams.
The following contributing factors were reported:
- Incorrect calculation of the dimensions of the shaped couplings and diameter of the rivets,
- Inaccurate record of the repairs in the aircraft logbook,
- Only spars n°2 and 6 were reported in the logbook, not spars n°4 and 8,
- The aircraft was overloaded by 562 kilos upon takeoff from Nikolayevsk-on-Amur as its total weight was 6,862 kg.
