## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

ON JUNE 29, 2025 AT 1033 MDT, A PRIVATELY OWNED PIPER PA-24-260, WITH ONE PILOT AND ONE PASSENGER ON BOARD, PERFORMED A GEAR UP LANDING AT YELLOWSTONE AIRPORT, WEST YELLOWSTONE, MONTANA. THE AIRCRAFT SUSTAINED SUBSTANTIAL DAMAGE TO THE FUSELAGE, PROPELLER, AND ENGINE. DURING THE INVESTIGATION THE PILOT STATED THAT HE EXPERIENCED AN ELECTRICAL FAILURE AT 13,500 FEET OVER DILLON, MONTANA. HE DECIDED TO CONTINUE ON TO WYS BECAUSE HE HAD HOTEL RESERVATIONS THERE. ON DOWNWIND AT WYS HE MOVED THE GEAR HANDLE TO THE DOWN POSITION AND HEARD IT DEPLOY. HE DID NOT RECEIVE A GEAR DOWN INDICATION DUE TO THE ELECTRICAL FAILURE. HE MADE THE TURN TO FINAL AND LANDED. HE STATED THAT THE AIRCRAFT ROLLED OUT AND EVENTUALLY THE GEAR COLLAPSED AND THE AIRCRAFT SLID FOR 40 TO 50 FEET. WHEN ASKED IF HE REMOVED THE MANUAL GEAR HANDLE PANEL AND PERFORMED THE MANUAL GEAR EXTENSION PROCEDURE, HE REPLIED THAT HE DID NOT BECAUSE HE HEARD THE GEAR EXTEND. AN AIRPORT EMPLOYEE WAS IN THE GRASS AT THE TAXIWAY A2/1-119 INTERSECTION. HE STATED THAT HE OBSERVED THE AIRCRAFT GO BY AT APPROXIMATELY 10 FEET ABOVE THE RUNWAY AND THE GEAR APPEARED TO BE PARTIALLY DEPLOYED. DURING THE INVESTIGATION THE SLIDE MARKS ON THE RUNWAY WERE MEASURED WITH A MEASURING WHEEL. THERE ARE PROPELLER STRIKE MARKS FOR 49 FEET THEN NO MARKS FOR 209 FEET. PROPELLER STRIKE MARKS AND A YELLOW-COLORED MARK START AGAIN AT 258 FEET AND CONTINUE FOR 478 FEET BEFORE WIDENING WHEN THE FUSELAGE FULLY CONTACTED THE RUNWAY. THE WIDER MARKS CONTINUE FOR 810 FEET. PROPELLER STRIKE MARKS ENDED AT 1,078 FEET FROM THE START OF MARKS. TOTAL DISTANCE FROM THE FIRST MARK TO THE END MEASURES 1,546 FEET.
