Alliance Air Flight 7412 departed Calcutta (Kolkata) at 06:51 on July 17, 2000, for a flight to Delhi, with stops at Patna and Lucknow. The crew had been cleared to land at runway 25 at Lok Nayak Jayaprakash Airport at Patna when the pilots requested a 360-degree orbit due to the flight being high on the approach. Permission was granted and a left turn was initiated. During the left turn, the aircraft stalled. The plane then grazed a few single-storied houses in a government residential housing estate and crashed in a government residential colony behind Gardani Bagh Girls School at Anishabad, which is located about 2 km southwest of the Patna Airport.[1] The aircraft broke into four pieces.


The aircraft in question, VT-EGD, had been involved in an earlier accident. On January 15, 1986, the pilot of flight 529 attempted to land at Tiruchirapalli in conditions below weather minima. During a go-around the wing contacted the runway due to an excessive bank angle. The wing was substantially damaged, but there were no injuries among the 6 crew and 122 passengers.[1] The aircraft was to be phased out by the end of the year per Indian government guidelines which do not allow aircraft over 20 years old to operate in Indian airspace.[2]

However, the final investigation noted pilot error as the cause of the plane crash.[3] According to the panel, the crew had not followed the correct approach procedure, which resulted in the aircraft being high on approach. The engines had been kept at idle thrust, which allowed the air speed to decline below the allowed minimum for approach and caused the aircraft to stall. The inquiry also pointed out that the airport had "several operational constraints, resulting in erosion of safety margins for operation of Airbus 320s and Boeing 737s."

The flight crew consisted of captain Manjit Singh Sohanpal and co-pilot Arvind Singh Bagga. A criminal case, filed against them based on the statement of a surviving passenger, was later withdrawn.[4][5] Both Captain Sohanpal and co-pilot Bagga died in the accident.[6]


There were a number of aspersions cast on the maintenance of flights by Alliance Air, with the then civil aviation minister Sharad Yadav reportedly unhappy with the maintenance of the aircraft [7] and asking for replacement of a number of additional aircraft.[7] Some reports even claimed that one of the engines was on fire before the crash.[8] However, the investigation clearly said the aircraft was fully airworthy and was properly maintained.[9]
