NTSB narrative
THE ACFT WAS LANDED GEAR-UP IN A FLD FOLLOWING A LOSS OF PWR DURING AN INITIAL TAKEOFF CLIMB. PURPOSE OF THE FLT WAS TO CHECK THE ENG AS IT HAD BEEN DISASSEMBLED BECAUSE OF METAL CONTAMINATION FROM THE CENTER MAIN BEARING. POST ACCIDENT INSPECTION OF THE ENG DISCLOSED THE #1, #2 AND #4 CYLINDER SPARK PLUG ELECTRODES WERE PEENED WITH BROKEN OUT SECTIONS AND CERAMIC POSTS. THE RESPECTIVE CYLINDER BARRELS AND PISTON HEADS WERE FOUND BADLY MARKED. THE #3 PISTON HEAD WAS SLIGHTLY MARKED AND PEENING WAS BISIBLE ON THE VALVE HEADS. INTAKE AND EXHAUST PIPES SHOWED SCRAPE MARKS WHEN REMOVED. A 1/8 INCH PIECE OF ALUMINUM PIPE WAS FOUND INSIDE THE #4 INTAKE PIPE.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
