What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Pilot advised the acft had a problem and subsequently made an emergency landing. (.4) shortly after takeoff the pilot heard a sound then felt a vibration. She advised ATC of this while turning to return, but the engine experienced a loss of power. She then maneuvered the airplane for a forced landing to a school field, and landed downwind farther than anticipated. The airplane bounced, and while airborne, collided with a fence, then collided with another fence and came to rest with the fuselage nearly vertical. Examination of the engine revealed sufficient quantity of engine oil. The cylinder walls of nos. 1 and 3 cylinders were noted to be dry when the engine examined 6 days later, and the no. 3 cylinder connecting rod was broken. No evidence of lack of lubrication was noted on the crankshaft journals. The no. 3 main bearing was noted to be extruded when examined. Examination of the recovered connecting rod components by the NTSB metallurgical laboratory revealed overstress failure to the components that did not exhibit mechanical damage to fracture surfaces. The thickness of a recovered bearing shell fragment was measured to be .019 to .022 inch; the specified thickness of the connecting rod bearing steel back is .056 to .066 inch. (-23) approximately 5 miles east of tamiami airport, while attempting a climb to 1500' MSL, pilot experienced vibration, attempted to turn back to departure airport. Realized she would not be able to make tamiami airport and decided to land in an open area of a high school playground. Attempted a downwind landing, overshooting field, running thru chainlength, striking fireplug, and ending on nose. (Vertically)
As the FAA filed it
PILOT ADVISED THE ACFT HAD A PROBLEM AND SUBSEQUENTLY MADE AN EMERGENCY LANDING. (.4) SHORTLY AFTER TAKEOFF THE PILOT HEARD A SOUND THEN FELT A VIBRATION. SHE ADVISED ATC OF THIS WHILE TURNING TO RETURN, BUT THE ENGINE EXPERIENCED A LOSS OF POWER. SHE THEN MANEUVERED THE AIRPLANE FOR A FORCED LANDING TO A SCHOOL FIELD, AND LANDED DOWNWIND FARTHER THAN ANTICIPATED. THE AIRPLANE BOUNCED, AND WHILE AIRBORNE, COLLIDED WITH A FENCE, THEN COLLIDED WITH ANOTHER FENCE AND CAME TO REST WITH THE FUSELAGE NEARLY VERTICAL. EXAMINATION OF THE ENGINE REVEALED SUFFICIENT QUANTITY OF ENGINE OIL. THE CYLINDER WALLS OF NOS. 1 AND 3 CYLINDERS WERE NOTED TO BE DRY WHEN THE ENGINE EXAMINED 6 DAYS LATER, AND THE NO. 3 CYLINDER CONNECTING ROD WAS BROKEN. NO EVIDENCE OF LACK OF LUBRICATION WAS NOTED ON THE CRANKSHAFT JOURNALS. THE NO. 3 MAIN BEARING WAS NOTED TO BE EXTRUDED WHEN EXAMINED. EXAMINATION OF THE RECOVERED CONNECTING ROD COMPONENTS BY THE NTSB METALLURGICAL LABORATORY REVEALED OVERSTRESS FAILURE TO THE COMPONENTS THAT DID NOT EXHIBIT MECHANICAL DAMAGE TO FRACTURE SURFACES. THE THICKNESS OF A RECOVERED BEARING SHELL FRAGMENT WAS MEASURED TO BE .019 TO .022 INCH; THE SPECIFIED THICKNESS OF THE CONNECTING ROD BEARING STEEL BACK IS .056 TO .066 INCH. (-23) APPROXIMATELY 5 MILES EAST OF TAMIAMI AIRPORT, WHILE ATTEMPTING A CLIMB TO 1500' MSL, PILOT EXPERIENCED VIBRATION, ATTEMPTED TO TURN BACK TO DEPARTURE AIRPORT. REALIZED SHE WOULD NOT BE ABLE TO MAKE TAMIAMI AIRPORT AND DECIDED TO LAND IN AN OPEN AREA OF A HIGH SCHOOL PLAYGROUND. ATTEMPTED A DOWNWIND LANDING, OVERSHOOTING FIELD, RUNNING THRU CHAINLENGTH, STRIKING FIREPLUG, AND ENDING ON NOSE. (VERTICALLY)
