Operated by Endeavor Air (per NTSB report)

An inadvertent encounter with severe turbulence during descent.

Operated by Endeavor Air (per NTSB report)

Operated by Endeavor Air (per NTSB report)

the failure of the captain of Delta 212 to ensure adequate clearance while taxiing behind Endeavor 3413.

Operated by Endeavor Air (per NTSB report)

A Bombardier CRJ200 No. 2 engine failure due to the separation of a fan blade airfoil at a low cycle fatigue crack that originated at the forward fan blade pin hole attachment. The separated fan blade had previously undergone a hot form repair and both metallurgical analysis and repair records indicated that the lance/shot peen step required to restore sufficient residual stress levels to the blade material was not completed.

Operated by Endeavor Air (per NTSB report)

The local controller's failure to visually scan and ensure that the runway surface was not occupied by a vehicle or other aircraft before issuing a takeoff clearance to the pilot. Contributing to this incident was the relieved controller's failure to monitor and review the position, after completing the relief briefing, to ensure that nothing had been overlooked.
