A Beechcraft B200GT King Air 250, transporting remdesivir injections meant for critical COVID-19 patients, suffered an accident during an attempted landing on runway 06R at Gwalior Airport (GWL/VIGR), Madhya Pradesh, India. All three occupants were injured. Approaching the joint military and civilian airport at Gwalior the crew were advised by ATC that runway 24L was in use. ATC then asked the crew if they would like to carry out a VOR approach for the opposite runway 06R. The crew requested for a night visual approach for runway 06R and were cleared to descend 2700 ft. After reporting that they had the airport in sight, the crew were cleared to circuit altitude. The first officer called turning right base with field visual and the flight was cleared to land which the crew acknowledged. Just before landing the aircraft and short of the threshold, the main gear collided with the raised arrester barrier and came to a halt on the runway 06R just beyond the threshold markings. Since Gwalior is a joint military/civil airport, the barrier nets were used to prevent military jets from overrunning runway 24L and were inadvertently left in a raised position. Probable cause of the Accident: 1) The PIC (PF) carrying out a visual approach at night and knowingly deviated below the visual approach path profile (3 degrees) while disregarding the PAPI indications, thereby the aircraft collided with the raised Arrester Barrier. 2) Lack of Assertiveness on the part of the Co-pilot (PM). Contributory Factors: 1) Non-Compliance to the SOP of “Change of Runway Checklist” by the ATC staff leading to the “Arrester Barrier” remaining in a “Raised Position” while the aircraft (VT-MPQ) came in for landing on runway 06R. 2) Non-essential conversation by the flight crew during the final approach for landing causing distraction leading to a delayed sighting of the raised Arrester Barrier. 3) Systemic failure at various levels at the Gwalior Air Force Base to ensure that the “Arrester Barrier Position Indicator Lights and Integral Panel Lights” were not rectified in a stipulated time period. 4) A robust alternate procedure was not defined when the “Arrester Barrier Position Indicator Lights and Integral Panel Lights” were unserviceable. 5) The Gwalior Airforce Base authorities did not install “Red Obstacle Lights” on the Arrester Barrier Poles to indicate the position of the obstacle on the date of the accident as per the DGCA requirements (CAR Section 4, Series B, Part 1).
