What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
On January 19, 2014, FAA certificated private pilot privacy data omitted operated civil aircraft N52314, a Cessna 182P serial number 18262521 on three flight legs. The aircraft was operated under part 91 rules and was rented from universal aviatiors academy inc, 4233 santa anita ave ste 13, el mote California. According to the pilot's statement the flight legs from san gabriel valley airport (EMT) to big bear city airport (rbf), and from rbf to brown field municipal airport (sdm) were uneventful except for an engine usage and oil temperature higher than normal but within service limts, and engine oil pressure on the low side of safe operating range. On the flight from sdm to EMT, the same conditions existed with the pilot reporting the low oil pressure and high oil temperature readings were not outside the normal range however while crossing the elb VOR the oil pressure decreased farther but was still above the red line. At approximately 1910 PST the aircraft was 3 miles south of the pom VOR at 4000MSL when the engine made a sudden, loud popping sound, the passenger cabin was filled with smoke, and the engine experienced a sudden stoppage. Socal TRACON vectored the flight to the nearest airfieled, Brackett airport (poc). The pilot established best glide speed and made a power off landing on runway 26L at poc without further incident. Post flight teardown and examination of the engine revealed that the engine, a normally aspirated Continental motors O-470, had experienced an uncontained engine failure due to loss of lubrication and subsequent failure of the crankshaft rotating components. The engine also exhibited signs of combustion chamber detonation with number one piston having a rectangular burn-through hole measuring approximately 1/2 by 1/4 inch just below the compression rings. The factors causing the detonation and loss of engine lubrication are unlnown at this time and are still under investigation.
As the FAA filed it
ON JANUARY 19, 2014, FAA CERTIFICATED PRIVATE PILOT ^PRIVACY DATA OMITTED^ OPERATED CIVIL AIRCRAFT N52314, A CESSNA 182P SERIAL NUMBER 18262521 ON THREE FLIGHT LEGS. THE AIRCRAFT WAS OPERATED UNDER PART 91 RULES AND WAS RENTED FROM UNIVERSAL AVIATIORS ACADEMY INC, 4233 SANTA ANITA AVE STE 13, EL MOTE CALIFORNIA. ACCORDING TO THE PILOT'S STATEMENT THE FLIGHT LEGS FROM SAN GABRIEL VALLEY AIRPORT (EMT) TO BIG BEAR CITY AIRPORT (RBF), AND FROM RBF TO BROWN FIELD MUNICIPAL AIRPORT (SDM) WERE UNEVENTFUL EXCEPT FOR AN ENGINE USAGE AND OIL TEMPERATURE HIGHER THAN NORMAL BUT WITHIN SERVICE LIMTS, AND ENGINE OIL PRESSURE ON THE LOW SIDE OF SAFE OPERATING RANGE. ON THE FLIGHT FROM SDM TO EMT, THE SAME CONDITIONS EXISTED WITH THE PILOT REPORTING THE LOW OIL PRESSURE AND HIGH OIL TEMPERATURE READINGS WERE NOT OUTSIDE THE NORMAL RANGE HOWEVER WHILE CROSSING THE ELB VOR THE OIL PRESSURE DECREASED FARTHER BUT WAS STILL ABOVE THE RED LINE. AT APPROXIMATELY 1910 PST THE AIRCRAFT WAS 3 MILES SOUTH OF THE POM VOR AT 4000MSL WHEN THE ENGINE MADE A SUDDEN, LOUD POPPING SOUND, THE PASSENGER CABIN WAS FILLED WITH SMOKE, AND THE ENGINE EXPERIENCED A SUDDEN STOPPAGE. SOCAL TRACON VECTORED THE FLIGHT TO THE NEAREST AIRFIELED, BRACKETT AIRPORT (POC). THE PILOT ESTABLISHED BEST GLIDE SPEED AND MADE A POWER OFF LANDING ON RUNWAY 26L AT POC WITHOUT FURTHER INCIDENT. POST FLIGHT TEARDOWN AND EXAMINATION OF THE ENGINE REVEALED THAT THE ENGINE, A NORMALLY ASPIRATED CONTINENTAL MOTORS O-470, HAD EXPERIENCED AN UNCONTAINED ENGINE FAILURE DUE TO LOSS OF LUBRICATION AND SUBSEQUENT FAILURE OF THE CRANKSHAFT ROTATING COMPONENTS. THE ENGINE ALSO EXHIBITED SIGNS OF COMBUSTION CHAMBER DETONATION WITH NUMBER ONE PISTON HAVING A RECTANGULAR BURN-THROUGH HOLE MEASURING APPROXIMATELY 1/2 BY 1/4 INCH JUST BELOW THE COMPRESSION RINGS. THE FACTORS CAUSING THE DETONATION AND LOSS OF ENGINE LUBRICATION ARE UNLNOWN AT THIS TIME AND ARE STILL UNDER INVESTIGATION.
