PATNA, June 13 -- The air crash in Ahmedabad is a chilling reminder of the Alliance Air Boeing 737-2A8 flight (CD 7412) crash in Patna on July 17, 2000, killing 55 people on board the aircraft and five on ground. The incident happened in the morning around 7.30am at Patna's Gardanibagh area, barely 2km from the runway of the Jayprakash Narayan International (JPNI) airport, when the aircraft from Kolkata to Patna enroute Delhi was landing. Air Marshal Philip Rajkumar, who probed the crash as part of the board of inquiry appointed by the ministry of civil aviation on August 8, blamed the crash due to pilot error. In its final report, the Directorate General of Civil Aviation (DGCA) concluded that the pilots (pilot-in-command captain Bagga and co-pilot captain Sohanpal) opted to execute a go-around (360-degree orbit) instead of a stall recovery procedure, when the aircraft was on its approach with engines at idle thrust, causing the aircraft to stall. The flight departed Kolkata at 6.51am on July 17, 2000 to New Delhi, with stop-overs at Patna and Lucknow, carrying 52 passengers and six crew, when the pilots noticed their altitude was much higher than the usual altitude for an approach and requested the Patna Air Traffic Control for a go-around, which it granted. However, while negotiating a left turn, the aircraft kept losing altitude and eventually grazed trees and a single-storied government quarter, crashing in a government residential colony behind the Gardanibagh Girls School at 7.34am. The aircraft, manufactured in 1980, was to be phased out by the end of the year as per the Indian aviation guidelines, which did not allow aircraft over 20 years old to operate in Indian airspace....
