From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

After takeoff at approximately 5000 ft, the pilot in command (PIC) stated that manifold pressure had inadvertently reduced. The pilot pushed up throttle to maximum to re-gain lost pressure. The PIC then noticed fluctuations in manifold pressure. ATC was contacted and PIC requested return to mpe. Just prior to reaching 2000 feet at 4 to 5 miles from the field, the PIC noticed oil pressure fluctuations coupled with manifold pressure fluctuations, an emergency was declared. At 2000 feet,between 4 and 5 miles from the field, the engine stopped running. The PIC made the determination that the airport was out of reach, and opted to land on a two lane highway (ms highway 21). An off-field landing ensued. Damage to the aircraft was limited to the right leading edge outboard section and the radar radome attached under the right wing. This damage was caused by the wing hitting a street sign during landing. Upon inspection of the engine by a certificated mechanic at the scene, it was determined that a connecting rod had broken through the engine casing above the number 3 cylinder. This event was caused by a catastrophic engine failure in flight. Aircraft was within current annual inspection date. The aircraft had satisfactory fuel samples, and approximately 20 to 25 gallons of fuel on board.

As the FAA filed it

AFTER TAKEOFF AT APPROXIMATELY 5000 FT, THE PILOT IN COMMAND (PIC) STATED THAT MANIFOLD PRESSURE HAD INADVERTENTLY REDUCED. THE PILOT PUSHED UP THROTTLE TO MAXIMUM TO RE-GAIN LOST PRESSURE. THE PIC THEN NOTICED FLUCTUATIONS IN MANIFOLD PRESSURE. ATC WAS CONTACTED AND PIC REQUESTED RETURN TO MPE. JUST PRIOR TO REACHING 2000 FEET AT 4 TO 5 MILES FROM THE FIELD, THE PIC NOTICED OIL PRESSURE FLUCTUATIONS COUPLED WITH MANIFOLD PRESSURE FLUCTUATIONS, AN EMERGENCY WAS DECLARED. AT 2000 FEET,BETWEEN 4 AND 5 MILES FROM THE FIELD, THE ENGINE STOPPED RUNNING. THE PIC MADE THE DETERMINATION THAT THE AIRPORT WAS OUT OF REACH, AND OPTED TO LAND ON A TWO LANE HIGHWAY (MS HIGHWAY 21). AN OFF-FIELD LANDING ENSUED. DAMAGE TO THE AIRCRAFT WAS LIMITED TO THE RIGHT LEADING EDGE OUTBOARD SECTION AND THE RADAR RADOME ATTACHED UNDER THE RIGHT WING. THIS DAMAGE WAS CAUSED BY THE WING HITTING A STREET SIGN DURING LANDING. UPON INSPECTION OF THE ENGINE BY A CERTIFICATED MECHANIC AT THE SCENE, IT WAS DETERMINED THAT A CONNECTING ROD HAD BROKEN THROUGH THE ENGINE CASING ABOVE THE NUMBER 3 CYLINDER. THIS EVENT WAS CAUSED BY A CATASTROPHIC ENGINE FAILURE IN FLIGHT. AIRCRAFT WAS WITHIN CURRENT ANNUAL INSPECTION DATE. THE AIRCRAFT HAD SATISFACTORY FUEL SAMPLES, AND APPROXIMATELY 20 TO 25 GALLONS OF FUEL ON BOARD.
