NTSB investigators traveled in support of this investigation and used data obtained from various sources to prepare this aircraft accident report.
The airplane crashed about 4 miles southwest of the runway 5L threshold during an ILS approach. The captain had associated the illumination of the left engine IGN light, illuminated as a result of a momentary negative torque condition when the propeller speed levers were advanced tp 100% and the power levers were at flight idle, with an engine failure. There was no evidence of an engine failure. The captain failed to follow established procedures for engine failure identification, single engine appoach, single engine go-around, and stall recovery. AMR Eagle training did not adequately address the recognition of engine failure at low power, the aerodynamic effects of asymmetric thrust from a 'windmilling' propeller, and high thrust on the other engine. AMR Eagle and Flagship Airlines crew training records do not provide sufficient detail for management to track performance. Flagship Airlines management was deficient in its knowledge of the types of crew records available, and in the content and use of such records.
