The certificated flight instructor and student pilot were not injured; and a passenger sustained minor injuries. Visual meteorological conditions prevailed, and no flight plan was filed for the local instructional flight conducted under 14 CFR Part 91. The flight instructor stated that he completed some "airwork" and landed at 8B8. He decided to do one more takeoff and landing, and departed on Runway 30. About 200 feet above-ground-level the engine quit, and the pilot ditched the airplane in Lake Winnipesaukee. After the accident, he moved the fuel selector from "BOTH" to "OFF". He added that before the accident, he flew .7 hours according to the tachometer. The airplane was removed from the lake and placed in a hangar. On October 4, 1999, a Federal Aviation Administration Inspector examined the wreckage. He drained approximately 11 gallons of fuel from the fuel tanks. He did not find any pre-impact mechanical malfunctions. Subsequently, the airplane's owner examined the wreckage with the assistance of a mechanic. They did not find any pre-impact mechanical malfunctions. ## Aircraft - Registration: [N6921X](https://openairdocs.org/deregistered/N6921X-2013-09-30), registration cancelled 2013-09-30, S/N 17247821, built 1960 (OpenAirDocs) - Reported make and model: Cessna 172 - Registry model: [Cessna 172B](https://openairdocs.org/model/cessna-172b) (registry code 2072406) (OpenAirDocs) - Registry engine: [Continental 0-300 series](https://openairdocs.org/engine/continental-0-300-series) (registry code 17022, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 17247821 - Airframe hours: 5522 - Engines: Continental O-300D 145 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Registered owner: Lakes Region Aviation Inc. - Airworthiness certificate: Standard, Utility - Last inspection: Annual, July 30, 1999, 48 hours before - Departed: 8B8 - Airport: 8B8, Lakes Region Airport, runway 30, 2,540 × 50 ft, asphalt ## Flight crew As NTSB recorded them.
