Narrative:
Air-India Flight 306, a Boeing 747-200B registered VT-EFO, landed at Delhi Airport at 20:10 hrs and was cleared for parking on bay No 17 via taxiway C (behind bay No 12).
Earlier, Indian Airlines Airbus A300 VT-EFV had landed and was parked at bay No 12 . To rectify a radar snag, the Airbus was positioned facing west, opposite to its normal parking position. After rectification, while the Airbus was being manoeuvred to its initial position, it got stuck 90 ft behind the marked parking position thereby forming an obstruction to aircraft taxying on taxiway C. The Boeing 747 aircraft on its way to bay No 17 hit the tail portion of the stationary Airbus. Both aircraft sustained substantial damage.
The cause of collision was failure on the part of the Indian Airlines to inform ATC and IAAI when their aircraft was forming an obstruction to the aircraft taxying on C taxiway and failure of the pilot-in-command of Air India Boeing 747 to exercise caution during taxying even when signaled to deviate from centreline of C taxiway.
The contributory factor was lack of co-ordination between and within the concerned agencies which are required to ensure safe movement of the aircraft at the airport.
