The Hendrick Motorsports plane that crashed last month and killed all 10 aboard missed the approach to the airport and then failed to immediately climb before crashing into a mountain, according to a preliminary report Friday.
The National Transportation Safety Board said the proper procedure after a missed approach at Blue Ridge Airport in Spencer called for the aircraft to maneuver right and climb to 2,600 feet.
Instead, the report said, the Beech 200 King Air descended to 1,800 feet before crashing into of Bull Mountain at an altitude of 2,450 feet.
The plane crashed Oct. 24 en route from Concord, N.C., to Martinsville Speedway. The son, brother and two nieces of owner Rick Hendrick, patriarch of one of NASCAR's top syndicates, were killed.
