Analysis
On February 1, 1994, at 2140 central standard time, a Saab 340B, N3495B, operated by Simmons Airlines as American Eagle flight 3641, sustained substantial damage during a forced landing at the False River Air Park in New Roads, Louisiana. The flight had been requested to descend by air traffic control from FL210, into Baton Rouge, Louisiana. The flightcrew stated after the accident that the captain was at the controls during the descent, and while passing through about 10,000 feet MSL, with the engine power levers in the flight idle position, a "loud roar" was heard followed by a loss of power on both engines. Passengers and the flight attendant stated that following the "roar," they observed "flames" or "sparks" coming from the rear of each engine.
The captain continued the descent and attempted several inflight emergency airstarts, however, they were unsuccessful. The first officer observed the lights of an airport and directed the captain to the runway where he executed a dual-engine out approach. The airplane touched down on runway 18 and continued off the end of the runway, accross the grass and a ditch, and came to rest upright on all three landing gear in a sugar cane field.
The passengers were evacuated via the airstair door.
