The pilot tried to recover by applying full power and initiating a go-around but realized that the airplane was not climbing at a sufficient rate to clear power lines. As the pilot pulled back on the control stick to try to increase the rate of climb, the airplane stalled. The pilot pushed the controls forward to recover from the stall and maneuvered the airplane toward a swamp area to avoid impacting trees. The airplane landed hard in the swamp area beyond the extended runway centerline and sustained substantial damage to the fuselage and left wing. A postaccident examination of the airplane did not reveal evidence of mechanical malfunctions which could have contributed to the accident. ## Factual narrative The pilot reported that the airplane hit hard upon touchdown and bounced. The pilot tried to recover by applying full power and initiating a go-around but realized that the airplane was not climbing at a sufficient rate to clear a set of power lines. As the pilot pulled back on the control stick to try to increase the rate of climb, the airplane stalled. The pilot pushed the controls forward to recover from the stall and maneuvered the airplane toward a swamp area to avoid impacting a stand of trees. The airplane landed hard in the swamp area beyond the extended runway centerline, and sustained substantial damage to the fuselage and left wing. A postaccident examination by a Federal Aviation Administration inspector did not reveal evidence of mechanical malfunctions which could have contributed to the accident. ## Aircraft - Registration: [N4375E](https://openairdocs.org/aircraft/N4375E), registered now, S/N 7DC-35, built 1948 (OpenAirDocs) - Reported make and model: AERONCA 7DC - Registry model: [Aeronca 7DC](https://openairdocs.org/model/aeronca-7dc) (registry code 2110116) (OpenAirDocs) - Category: Airplane - Serial number: 7DC-35 - Airframe hours: 2159 - Engines: Continental C85-8F 85 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Hampton Airfieild Inc - Registered owner: Hampton Airfieild Inc - Airworthiness certificate: Standard, Normal - Last inspection: Annual, May 20, 2011 - Departed: 7B3, North Hampton, NH - Destination: 7B3, North Hampton, NH - Airport: N/A, Sanderson's Field, runway 07, 2,500 × 50 ft, dirt ## Flight crew As NTSB recorded them.
