INVESTIGATION: I WAS NOTIFIED OF AN ACCIDENT THAT CAME TO THIS OFFICE THROUGH A PHONE CALL FROM THE REGIONAL OPERATIONS CENTER (ROC) ON 03/15/2023. ON 03/15/ 2023, THE PILOT^PRIVACY DATA OMITTED^ OF A CESSNA C-177 RG AIRPLANE WAS FLYING ON A PART 91 PERSONAL FLIGHT FROM THE PROVO, UTAH AIRPORT TO THE SPANISH FORK MUNICIPAL AIRPORT (KSPK). THE PILOT REPORTED THAT TWO WEEKS PRIOR TO THIS FLIGHT HE HAD WORK PERFORMED ON THE AIRCRAFT’S LANDING GEAR HYDRAULIC PUMP. ADDITIONALLY, ON THE DAY PRIOR AND THE DAY OF THE FLIGHT, THE PILOT STATED THAT ADDITIONAL WORK WAS PERFORMED RELATED TO THE LANDING GEAR PUMP. THE PILOT STATED THAT THE LANDING GEAR PUMP WOULD RUN PERIODICALLY FOR NO REASON. JUST PRIOR TO THE FLIGHT, THE PILOT STATED THAT HE HAD MAINTENANCE PERSONNEL REPLACE SOME WIRING AND DIODES IN THE LANDING GEAR SYSTEM. THE WORK WAS PERFORMED, AND THE WORK WAS SIGNED OFF IN THE AIRCRAFT LOGBOOK. THE PILOT TOOK OFF FROM KPVU AIRPORT AND HEADED SOUTH TO KSPK AIRPORT TO LAND. THE PILOT STATED THAT DURING TAKEOFF AND LANDING THE LANDING GEAR LIGHTING SYSTEM APPEARED TO BE WORKING CORRECTLY. ON FINAL APPROACH TO KSPK AIRPORT, THE PILOT STATED THAT HE EXTENDED THE LANDING GEAR AND CONFIRMED THE LANDING GEAR WAS DOWN THROUGH THE VISUAL INSPECTION OF THE GEAR DOWN LIGHTS ON THE COCKPIT PANEL AND VISUAL CONFIRMATION THROUGH THE CONVEX MIRROR LOCATED OUTSIDE OF THE AIRCRAFT OF THE LANDING GEAR. AS THE PILOT MADE HIS LANDING TO KSPK AIRPORT, HE STATED THAT THE AIRCRAFT LANDING APPEARED NORMAL UNTIL HE APPLIED ADDITIONAL FLAPS TO 10?. IMMEDIATELY, THE PILOT STATED THAT HE OBSERVED THE AIRCRAFT’S NOSE START TO RAISE AND THE TAIL LOWER AND HE STATED THAT HE HEARD A SCRAPING NOISE. THE PILOT INITIALLY THOUGHT HE HAD BLOWN A TIRE AND THAT THE AIRCRAFT WAS RIDING ON THE RIM OF THE WHEEL. THE AIRCRAFT STARTED TO MAKE A TURN TO THE LEFT WHICH COULD NOT BE COUNTERACTED BY WITH RUDDER CORRECTION. THE AIRCRAFT SLID ACROSS THE RUNWAY WHERE THE AIRCRAFT’S PROPELLOR STRUCK A RUNWAY EDGE LIGHT. THE PILOT WAS ABLE TO BRING THE AIRCRAFT TO A FULL STOP. WHEN THE PILOT EXITED THE AIRCRAFT, HE FOUND THE AIRCRAFT RESTING ON THE NOSE WHEEL AND TAIL TIE DOWN RING. HE VISUALLY OBSERVED THAT THE AIRCRAFT’S MAIN LANDING GEAR WERE FOLDED BACK AND MOST OF THE WAY INTO THE WHEEL WELLS OF THE AIRCRAFT. THE PILOT STATED THAT HE THEN VISUALLY INSPECTED THE LANDING GEAR DOWN INDICATOR LIGHTS ON THE COCKPIT PANEL AND STATED THAT THE SYSTEM STILL INDICATED A GEAR DOWN AND LOCKED INDICATION GREEN LIGHT. THE PILOT STATED THAT THE AIRCRAFT SUSTAINED MINIMAL DAMAGE TO THE PROPELLOR AND LEFT STABILATOR. THERE WAS NO DAMAGE TO THE UNDERSIDE OF THE AIRCRAFT OR THE WINGS AS THE AIRCRAFT RESTED DIRECTLY ON TOP OF THE RUNWAY EDGE LIGHT THAT HAD DAMAGED THE PROPELLOR BUT KEPT THE AIRCRAFT UPRIGHT.
