Probable cause

A partial loss of engine power for reasons that could not be determined because examination of the engine and associated components did not reveal any mechanical malfunction or failure that would have precluded normal operation.

NTSB narrative

The pilot was performing a personal sightseeing flight over the Hudson River at 1,200 feet above mean sea level. She reported the airplane contained 74 gallons of fuel at takeoff. While abeam a tower, the engine began to partially lose power. The pilot initiated the emergency procedures in the checklist and applied carburetor heat. Engine performance worsened and the carburetor heat was left on for about 15 seconds. She then turned off the carburetor heat and engine performance improved. After about 20 seconds, the engine began to lose power again. Unable to maintain altitude, she made a mayday call and performed a forced landing on the river. The engine and airframe were inspected after the airplane was recovered from the river. The engine ingested a significant amount of mud and debris and many engine components were corroded. No evidence of preaccident mechanical malfunction or failure was found with the engine, ignition system, or carburetor that would have precluded normal operation. Damage from prolonged water submersion prevented a test run of the engine. The airplane was not being operated in weather conditions conducive to carburetor icing.
