A factor relating to the accident was: lack of suitable terrain for a forced landing. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of engine power(total) - mech failure/malf, cruise - engine assembly,crankshaft - failure (cause) - Forced landing, emergency descent/landing - On ground/water encounter with terrain/water, emergency landing - terrain condition - none suitable (contributing factor) - terrain condition - rough/uneven (contributing factor) ## Analysis The pilot reported that the airplane was level at 6000 feet MSL, when the engine lost power. He stated that his attempts to restart the engine included switching fuel tanks and using the boost pumps, but all were unsuccessful. A forced landing was made in a strip mine, where the airplane came to rest with substantial damage. An FAA Inspector stated that an engine teardown revealed that the crankshaft had failed in the vicinity of the two rear cylinders. Records indicated the engine had been operated 913 hours since major overhaul. ## Factual narrative On February 23, 1996, at 1315 eastern standard time (EST), a Cessna P210N, N90AD, lost engine power during descent, and made a forced landing near Hazard, Kentucky. The airplane sustained substantial damage during the forced landing. The certificated private pilot/registered owner, the sole occupant, received minor injuries. Visual meteorological conditions prevailed for the flight, and an IFR flight plan was filed. The business flight operated under 14 CFR Part 91. The flight originated from Reading, Pennsylvania, at 1130 EST. The intended destination was London, Kentucky. The pilot stated that the airplane was in cruise flight at 12,000 feet Mean Sea Level (MSL), when Air Traffic Control (ATC) issued a clearance to descend to 6,000 feet MSL. The pilot reported that approximately 2 minutes after he leveled the airplane at 6,000 feet MSL, he noticed that the fuel flow indicator started to fluctuate. He stated that about 30 seconds later "...the engine just quit, did not [sputter] or backfire, just quit." The pilot stated that he attempted to restart the engine, but was unsuccessful. The pilot made a forced landing in a strip mine. The aircraft was examined after the accident by a Federal Aviation Administration (FAA) Inspector. The Inspector stated that there was about 40 gallons of aviation fuel on board the airplane. The airplane was removed from the accident site, and an engine teardown was conducted. The FAA Inspector stated that the engine teardown revealed that the crankshaft had failed in the vicinity of the two rear cylinders. The pilot reported that the engine had operated 913 hours since major overhaul. The most recent maintenance inspection was an Annual Inspection, dated October 23, 1995. ## Aircraft - Registration: [N90AD](https://openairdocs.org/deregistered/N90AD-2013-08-22), registration cancelled 2013-08-22, S/N P21000156, built 1978 (OpenAirDocs) - Reported make and model: Cessna P210N - Registry model: [Cessna P210N](https://openairdocs.org/model/cessna-p210n) (registry code 2073454) (OpenAirDocs) - Registry engine: [Continental TSIO-520 series](https://openairdocs.org/engine/continental-tsio-520-series) (registry code 17040, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: P210-00156 - Airframe hours: 4376 - Engines: Continental TSIO-520-P 310 horsepower reciprocating - Damage: Substantial damage - Flight: Business, Part 91 - Operator: Robert H.

Lost power en route. Crash landed in strip mine. Crankshaft had failed. Only 913 hrs since new engine installed. From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
