## Narrative

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

(.19) ON NOVEMBER 2, 1999, APPROXIMATELY 1650 MOUNTAIN STANDARD TIME, A PIPER PA-18-150, N4285Z, WAS SUBSTANTIALLY DAMAGED WHEN IT DEPARTED THE SIDE OF THE RUNWAY AND COLLIDED WITH A FENCE DURING LANDING ROLL AT BULLFROG BASIN AIRPORT, BULLFROG, UTAH. THE PRIVATE PILOT AND AIRLINE TRANSPORT PILOT CERTIFICATED PASSENGER WERE NOT INJURED.  VISUAL METEOROLOGICAL CONDITIONS PREVAILED, AND A VFR FLIGHT PLAN HAD BEEN FILED FOR THE PERSONAL CROSS-COUNTRY FLIGHT BEING CONDUCTED UNDER TITLE 14 CFR PART 91.  THE FLIGHT ORIGINATED FROM CANYONLANDS FIELD AIRPORT, MOAB, UTAH, AT 1445. ACCORDING TO THE PILOT, PRIOR TO LANDING AT BULLFROG AIRPORT, HE CONTACTED THE AIRPORT'S UNICOM (UNIVERSAL INTEGRATED COMMUNICATION) FREQUENCY AND REQUESTED AN AIRPORT ADVISORY.  HE WAS TOLD THAT THE PREFERRED RUNWAY WAS 19.  HE APPROACHED THE AIRPORT FOR LANDING FROM THE SOUTHEAST AND NOTICED THAT THE WINDSOCK INDICATED THE WIND WAS CALM.  THE PILOT STATED THAT THE DOWNWIND, BASE AND FINAL APPROACH SEGMENTS TO RUNWAY 19 WERE "NORMAL."  HE LANDED THE AIRCRAFT JUST PAST THE RUNWAY THRESHOLD.  THE MAIN WHEELS TOUCHED DOWN FIRST, FOLLOWED BY THE TAIL WHEEL.  ACCORDING TO THE PILOT, THE AIRCRAFT CONTINUED IN A NORMAL LANDING ROLL, THEN VEERED TO THE RIGHT. THE AIRPLANE DEPARTED THE RUNWAY AND TRAVELED DOWN A 10 DEGREE EMBANKMENT, IMPACTING A FENCE AND SUSTAINING DAMAGE TO THE HORIZONTAL STABILIZER, BOTH RIGHT WING STRUTS, THE NOSE COWLING, AND PROPELLER.                                                          (-23)AFTER TOUCHDOWN AT THE BULLFROG AIRPORT THE A/C VEERED TO THE RIGHT OF THE RUNWAY AND HIT A FENCE.

## The NTSB's investigation of this event (1)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.

Probable cause: The pilot-in-command's failure to maintain directional control of the aircraft during landing roll. Factors were the pilot's lack of total experience in type of aircraft and the fence.
