Accident Overview
On December 13, 2023, about 1730 central standard time, a Cessna T210F airplane, registration N6789R, was substantially damaged during a forced landing near Sapulpa, Oklahoma. The pilot reported no injuries. The aircraft was operating as a personal flight under Title 14 Code of Federal Regulations Part 91.
Flight Details
The flight was intended to break in a recently overhauled engine. Shortly after takeoff, the engine lost all power, though the propeller continued windmilling. The pilot attempted to restore engine power but was unsuccessful. Unable to return to the airport, the pilot performed a forced landing to a road. During the landing, the pilot maneuvered to avoid a vehicle and landed hard. During the landing roll, the right main landing gear and nose landing gear struck a concrete curb, causing the nose gear to collapse. The fuselage and left wing sustained substantial damage.
Postaccident Examination
A postaccident examination of the engine revealed that the left magneto had seized and was partially separated from the engine. The internal components of the left magneto were heat damaged and melted, preventing further testing. The left magneto had been rebuilt and installed during the most recent engine overhaul, which occurred about one hour before the accident. The right magneto was confirmed to be grounded due to impact damage to its p-lead.
