The pilots had aborted one landing and were going around for a second attempt when the aircraft dropped into a residential area, killing 97 of the 99 on board.
Announcing the results of a preliminary investigation Wednesday, Khan said ‘overconfident’ pilot Sajjad Gull had attempted to land with the wheels up.
The pair had turned autopilot off and ignored repeated warnings from air traffic control that they were descending too fast and from too great an altitude.
Previous analysis of black box recordings also suggest Gull ignored alarms that were sounding in the cockpit as he made the failed landing.
Air traffic control saw the plane's engines scrape the runway, leaving them damaged, but did not warn the pilot before the plane pulled back into the sky, Khan said.
Both engines then failed, causing the crash.
"Investigators say Gull was 'distracted' by a conversation he was having during the landing - meaning he descended too fast and with the wheels up. The plane then scraped the runway, damaging both engines, before attempting another landing. On the go-around the engines failed, causing the crash"Neither did the 9-11 hijackers.............
