Analysis

The left engine failed during takeoff at an altitude of about 40 ft AGL. During the forced landing, the plt used incorrect emergency procedures and failed to maintain lateral and directional control of the acft. Inspection of the acft revealed a disintegrated left eng induction air filter had blocked the air box outlet, a misaligned air box prevented actuation of the alternate air source door and a bogus gasket had been installed between the air box flange attachment and the firewall.
