BEDFORD, Mass. (WHDH) -
The National Transportation Safety Board released a report Friday on the deadly plane crash at Hanscom Field last month.
Experts said their investigation shows that the crew may have failed to do a flight control check before taking off.
A preliminary report Friday from the National Transportation Safety Board on the May 31 crash at Hanscom Field also indicated a possible problem with a mechanical gust lock system, which protects aircraft components from wind damage while planes are parked. Aviation experts say the plane would have been unable to take off if the lock was engaged.
The investigation is still ongoing.
Seven people were killed when the small plane, headed to Atlantic City, went off the runway. The plane never made it off the ground, when it went down and exploded into flames.
One of the victims was Philadelphia Inquirer co-founder Lewis Katz. Other victims identified were Susan Asbell and Marcella Dalsey. The names of the three crew members have not been released. The Associated Press contributed to this report.
