NTSB summary
On November 30, 1996, at 0934 hours mountain standard time, a Cessna T210N, N4788C, was substantially damaged during a forced landing following a loss of power upon departure from Scottsdale, Arizona. The pilot and four passengers received serious injuries. Visual meteorological conditions prevailed for the personal cross-country flight and an IFR flight plan was filed. The flight was en route to San Diego, California. Postaccident examination of the engine revealed that the number 2 piston exhibited detonation/preignition damage with upper ring land failure and heavy piston scoring, erosion, and metal transfer to the piston skirt. A burn hole was observed through a piston ring groove into the interior of the piston. The top rings were fragmented. The lower ring was intact, but seized in its groove. The top edge of the piston crown was melted and eroded away over 80 percent of the piston circumference. The piston was shipped to the engine manufacturer for examination and analysis under the supervision of the FAA MIDO inspector. According to the report, the failure was caused by detonation/preignition due to undetermined causes. The report also listed some possible causes of this type of event. Both of the engine driven magnetos were shipped to the manufacturer's facility at Atlanta, Georgia. Functional testing and teardown examination was conducted under the supervision of the FAA MIDO inspector. According to the report, all installed parts were appropriate part numbers and in proper condition and adjustment. The magnetos were functional tested to the FAA approved TCM data.
Probable cause
detonation/pre-ignition for unknown reason(s), which resulted in failure of the number two piston, loss of engine power, and a subsequent forced landing on rough/uneven desert terrain.
