Incident
During approach to Arkhangelsk-Talagi Airport, the flight crew experienced technical difficulties with the landing gear. The landing gear could not be lowered normally. The crew made several manual attempts to extend the gear. Ultimately, only the right main landing gear remained retracted and stuck in its wheel well. The captain decided to proceed with the landing in this configuration. After touchdown, the aircraft slid on the runway surface, veered off the paved area, and came to rest in a grassy area adjacent to the runway.
Occupant Status
All 62 occupants on board evacuated the aircraft without injury. No injuries were reported among passengers or crew.
Aircraft Damage
The aircraft sustained substantial damage and was deemed beyond economical repair.
Investigation and Probable Cause
The official investigation determined that the right main gear could not be lowered because of a breakage of the filling connection of the hydraulic tank. This breakage was due to metal fatigue and occurred while the aircraft was taxiing at Moscow-Sheremetyevo Airport. The fitting was blown out under hydraulic pressure, which damaged adjacent hydraulic lines. This led to a loss of hydraulic fluid and a drop in oil pressure, preventing the right main gear from extending properly.
