Accident
The accident occurred during the final approach to Nagpur-Sonegaon Airport. The aircraft was operating under night conditions with limited visibility. On final approach, the aircraft descended below the required altitude, struck trees, banked left, and impacted terrain approximately 700 meters short of runway 27. The collision resulted in the deaths of one passenger and both pilots; 14 other occupants sustained injuries.
Investigation
The investigation focused on the approach configuration and altimeter settings. It was determined that the flying crew executed a wrong approach configuration by passing below the glide path and continuing the approach at an insufficient height. Contributory factors included a wrong altimeter setting: the crew conducted the approach using QNH mode instead of the required QFE setting.
Probable Cause
The probable cause, as stated by the official investigation, is: "Wrong approach configuration on part of the flying crew who decided to pass below the glide and continue the approach at an insufficient height. A wrong altimeter setting was considered as a contributory factor, the crew continued the approach in QNH mode instead of QFE."
