The pilot and two passengers received minor injuries. The flight originated in North Bass Island, Ohio destined for Madison, Ohio. Visual meteorological conditions prevailed. There was no flight plan. The flight was being conducted under CFR 14 Part 91. In the NTSB form 6120.1/2, the pilot stated, I departed North Bass Island, Ohio, at approximately 1600 hours, for Madison, Ohio, and developed engine trouble. I decided to try to make it to Lorain County Airport (22G), but due to further engine deterioration, I landed in a grass field approximately 2.5 miles from Lorain County Airport. Damage to the airplane occurred on landing due to rough terrain. A Federal Aviation Administration (FAA) Inspector examined the airplane and interviewed the pilot after the accident. Post Accident Examination by the FAA Inspector revealed that the engine magneto leads were "severely worn". The pilot reported to the FAA Inspector that he (the pilot) had been performing the maintenance on the airplane. According to the FAA Inspector the pilot did not hold a mechanic certificate with a powerplant rating. The pilot further reported that the airplane's last annual inspection was conducted on June 15, 1988. According to information supplied by the pilot in the NTSB form 6120.1/2, his last biennial flight review was "appprox. 1986." The pilot voluntarily surrendered his pilot's certificate to the FAA Safety Inspector. ## Aircraft - Registration: [N5360K](https://openairdocs.org/deregistered/N5360K-1994-09-02), registration cancelled 1994-09-02, S/N NAV42260B (OpenAirDocs) - Reported make and model: RYAN NAVION B - Registry model: [Ryan NAVION B](https://openairdocs.org/model/ryan-navion-b) (registry code 6150170) (OpenAirDocs) - Category: Airplane - Serial number: NAV-42260B - Airframe hours: 1373 - Engines: LYCOMING GO-435-C2 260 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Richard M.
