Moultonboro Airport
Aircraft Accident/Incident Report

Moultonboro, New Hampshire 03254
Saturday, July 14, 2001 18:30 EDT

NTSB Narrative Summary Released at Completion of Accident

Approaching the destination airport, the engine sputtered and then quit. The pilot performed a forced landing to a field with rough terrain, and during rollout, the right main landing gear hit a large hole. The right wing drove into the turf, the nose landing gear collapsed, and the airplane nosed over. On-scene examination of the airplane revealed that the right fuel tank was empty, but that the left fuel tank still had fuel. Further examination revealed that the main fuel vent line was clogged about 4 to 5 inches from the vent opening by a mud dauber nest. The clog would have been impossible to see during a preflight inspection.

NTSB Probable Cause Narrative

A clogged fuel vent line due to a mud dauber nest, and rough terrain, including a large hole, in the forced landing field.
