The Directorate Civil Aviation, which today made public its final investigation report on the incident involving a Boeing 737-800 aircraft, has also recommended both the pilots - the pilot-in-command and first officer - to undergo technical refresher course/crew resource management with special emphasis on taxing procedures as part of its safety recommendations.
"Taxing procedure as per Boeing FCTM was not followed by the commander, which eventually resulted into the incident," the DGCA said in its report.
The incident had happened when the port side winglet of the Hyderabad-bound aircraft with 137 passengers and seven crew onboard, hit the light mast while executing a left turn during the taxing for take-off.
However, all 144 people onboard had escaped unhurt in the incident, which took place on December 12, 2012.
