CRJ7, Kanpur India, 2011

Summary

On 20 July 2011, an Alliance Air CRJ 700 touched down over half way along the 9000 ft long runway at Kanpur after a stable ILS approach but with an unexpected limiting tailwind component and failed to stop before the end of the paved surface. Although an emergency evacuation was not necessary and there were no injuries, the aircraft was slightly damaged by impact with an obstruction. The subsequent investigation attributed the event to the commanders continued attempt at a landing when a late touchdown became increasingly likely.

Description

On 20 July 2011, a Bombardier CRJ 700 being operated on a scheduled domestic passenger flight from Dehli to Kanpur by Alliance Air overran the landing runway at destination after a late touchdown in normal daylight visibility. Although an emergency evacuation was not necessary and none of the 59 occupants were injured, the aircraft was slightly damaged.

Investigation

An Investigation was carried out by the DGCA. DFDR and Cockpit Voice Recorder (CVR) download was successful and the data was used to aid the Investigation. It was established that the aircraft commander was experienced and also designated as a Check Captain and been PF for the accident sector. However, the First Officer was inexperienced and the published extract from the CVR transcript showed no evidence of an effective monitoring role being performed.

The only damage to the aircraft was to the left wing leading edge which collided and destroyed part of the Instrument Landing System (ILS) LLZ antenna resulting in a hole of approximately 7.5 cm diameter being made in the wing.

It was noted that the airport is a military one with a civil terminal facility. The single 2750 metre long runway has arrester wires at the ends and intentionally soft ground beyond. ATC service is provided by the Indian Air Force.
