Détails:The crash occurred shortly before as the plane was preparing to land at Patuxent River Naval Air Station. The crew had been conducting tests of tracking equipment during the short flight from Davison Army Air Field at Fort Belvoir. The plane crashed sank into the water about 50 yards off shore from the Naval Air Station, in 45 feet deep water.
Reportedly, this aircraft crashed because the flight crew inadvertently selected "beta range" on the propellers at 800 feet. The aircraft then stalled and crashed into the river. The CASA aircraft was owned by the US Army Intelligence and Security Command (INSCOM) and carried both a military (88-0320) as well as civilian (N296CA) registration marks.

Opérations de secours
NTSB issued 2 Safety Recommendations
Issued: 19-DEC-1990 | To: FAA | A-90-181 |
ISSUE AN AIRWORTHINESS DIRECTIVE APPLICABLE TO THE CASA C-212, TO REQUIRE THE DESIGN AND INSTALLATION OF A SYSTEM THAT PROVIDES A POSITIVE MEANS OF PREVENTING THE POWER LEVERS FROM BEING PLACED BELOW THE FLIGHT IDLE POSITION WHILE THE AIRPLANE IS AIRBORNE. (Closed - Acceptable Action) |
Issued: 19-DEC-1990 | To: FAA | A-90-182 |
Conduct a directed safety investigation of all Garrett tpe-331 engine powered turbopropeller airplanes. This investigation should evaluate the potential for in flight use of the beta mode, and the effects of incorrectly adjusting the blade pitch angle of the propeller during maintenance activities and, following the directed safety investigation, take appropriate action to preclude in-flight beta operation on airplanes not approved for such operation. (Superseded by A-94-61, A-94-62, and A-94-63) (Closed - Acceptable Action/Superseded) |
