On May 19, 2003, a Cessna 175A (registration N6989E) was involved in an aviation accident near Ocean City, NJ. Investigators recorded the probable cause as: A partial loss of engine power for undetermined reasons. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
During initial climb, a partial power loss occurred. The pilot turned back but ditched in shallow water. Investigation found fuel and vent clear; engine started but did not continue running.
Incident Overview
During the initial climb at approximately 800 feet mean sea level, the airplane experienced a partial loss of engine power. The pilot executed a 180-degree turn in an attempt to return to the departure airport but was unable to maintain altitude. The airplane was subsequently ditched in shallow water approximately 2 miles south of the airport.
Pilot Statement
The pilot reported that the power loss may have been caused by an obstruction of the airplane's single fuel vent. However, examination of the wreckage revealed that both fuel tanks contained fuel and the fuel vent was not blocked.
Examination Findings
Post-accident examination of the engine did not reveal any pre-impact mechanical malfunctions. Investigators obtained thumb compression and valve train continuity. The engine initially started but did not continue to run. No determination of a specific cause for the power loss was made from the engine examination.
Conclusion
The circumstances leading to the partial power loss remain undetermined based on the available evidence.
