Piper PA-28RT-201T N2970G accident near Hernando Beach, Florida

Probable cause

A partial loss of engine power due to a blockage of the No. 6 cylinder fuel injector nozzle.

NTSB analysis

While en route over the Gulf of Mexico, the pilot reported that the engine began to run rough and experienced a partial loss of power. The pilot declared an emergency, searched for a place to land, and performed a gear-up landing in the water. The pilot egressed and was rescued by the U.S. Coast Guard. A postaccident engine examination revealed that the No.6 cylinder fuel injection nozzle was blocked with debris. After the fuel nozzle was cleaned and reinstalled, an engine run was performed. The engine started and ran smoothly, accelerated to maximum power without hesitation, and was shut down with no anomalies noted. It is likely that a small particle of debris in the fuel became lodged in the No. 6 fuel injection nozzle, which resulted in the loss of engine power.
