The pilot made a forced landing to a field, where the airplane struck a fence, before coming to rest in briar bushes. When the airplane's dual magneto system was examined, both sets of points remained closed, regardless of the camshaft position. ## Factual narrative On November 2, 2000, about 1200 Eastern Standard Time, a Cessna 177B, N35241, was substantially damaged after a forced landing near Prosperity, Pennsylvania. The certificated private pilot and pilot-rated passenger received minor injuries. Visual meteorological conditions prevailed and no flight plan was filed for the personal flight conducted under 14 CFR Part 91. According to the pilot, he and the passenger were practicing maneuvers, for the commercial pilot practical test. While at an altitude of about 2,500 feet above the ground, the pilot heard a loud "pop," and the engine lost all power. The pilot made a force landing to a field. After touching down in the field, the airplane struck a fence and came to rest in briar bushes. The pilot did not report any prior mechanical difficulties with the airplane's engine. The airplane's magneto system, a Teledyne Continental Motors D-3000 Magneto Ignition system, was forwarded to Teledyne Mattituck Services Inc., Mattituck, New York, on January 10, 2001, and examined in the presence of a Federal Aviation Administration inspector. The inspector observed that both sets of points remained closed, regardless of the cam position, when the magneto system was tested. The inspector also stated that all securing hardware torque seals were intact and there was no evidence of point adjustment shifting. A Safety Board investigator examined the magneto system on February 7, 2001. As the impulse coupling was turned, the lobes of the cam would not push the cam follower far enough to open the points. ## Aircraft - Registration: [N35241](https://openairdocs.org/deregistered/N35241-2003-09-25), registration cancelled 2003-09-25, S/N 17702285, built 1975 (OpenAirDocs) - Reported make and model: Cessna 177B - Registry model: [Cessna 177B](https://openairdocs.org/model/cessna-177b) (registry code 2073708) (OpenAirDocs) - Registry engine: [Lycoming O&VO-360 series](https://openairdocs.org/engine/lycoming-o-vo-360-series) (registry code 41514, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 17702285 - Airframe hours: 5886 - Engines: Lycoming O-360-A1F6D 180 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Abc Flying Club Inc - Airworthiness certificate: Standard, Normal - Last inspection: Annual, May 10, 2000, 96 hours before - Departed: AGC, WEST MIFFLIN, PA ## Flight crew As NTSB recorded them.
