## Narrative

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

(.19) ON JANUARY 21, 2002, AT 1630 HOURS PACIFIC STANDARD TIME, A CESSNA 206H, N72635, WAS SUBSTANTIALLY DAMAGED DURING LANDING ROLLOUT AT MAMMOTH LAKES AIRPORT, MAMMOTH LAKES, CALIFORNIA. THE PRIVATE RATED PILOT WAS NOT INJURED. THE PERSONAL FLIGHT WAS OPERATED BY THE PILOT UNDER 14 CFR PART 91. VISUAL METEOROLOGICAL CONDITIONS PREVAILED, AND NO FLIGHT PLAN WAS FILED. THE FLIGHT ORIGINATED AT SANTA ANA, CALIFORNIA, AT 1415, AND WAS DESTINED FOR MAMMOTH LAKES (MMH). ACCORDING TO THE PILOT, AT 0915, AND PRIOR TO DEPARTING SANTA ANA, HE CONTACTED THE FEDERAL AVIATION ADMINISTRATION RIVERSIDE FLIGHT SERVICE FOR A STANDARD PREFLIGHT WEATHER BRIEFING. BISHOP, CALIFORNIA, THE NEAREST OFFICIAL WEATHER REPORTING FACILITY 27 MILES SOUTH, WAS REPORTING VISUAL CONDITIONS WITH SURFACE WINDS OF 20 KNOTS GUSTING TO 35, CALMING THROUGH THE AFTERNOON. AT 1300, THE PILOT AGAIN CONTACTED THE RIVERSIDE FLIGHT SERVICE TO VERIFY THE WEATHER WAS VISUAL FLIGHT CONDITIONS. HE RECEIVED NOTICE THAT THE MAMMOTH AUTOMATED SURFACE OBSERVATION SYSTEM (ASOS) WAS REPORTING SURFACE WINDS OF 210 DEGREES AT 14 KNOTS WITH GUSTS TO 24 KNOTS. AT 1600, ABOUT 20 MILES SOUTH OF MMH, THE PILOT RECEIVED THE CURRENT ASOS, WHICH WAS REPORTING WINDS 210 DEGREES AT 25 KNOTS GUSTING TO 45. IT FURTHER REPORTED THAT RUNWAY 27 WAS IN USE AND TO AVOID LANDING ON THE FIRST 3,000 FEET DUE TO CROSSWINDS. THE PILOT CRABBED INTO THE WIND AS HE OVER FLEW THE FIRST 3,000 FEET OF RUNWAY 27. AS HE SLOWED TO ABOUT 30 KNOTS ON THE RUNWAY, A CROSSWIND GUST LIFTED THE LEFT WING CAUSING THE AIRPLANE TO TURN INTO A SNOW COVERED EMBANKMENT. SUBSEQUENTLY THE GUSTING WIND LIFTED THE TAIL UP AND OVER THE TOP TO AN INVERTED POSITION IN THE SNOW. (-23) PILOT HAD COMPLETED A TOUCHDOWN WITH FLAPS DOWN AT MAMMOTH AIRPORT WITH WINDS REPORTED 210 DEGREES 25 KTS GUSTING TO 45 KTS. PILOT WAS LANDING ON RUNWAY 27. UPON ROLLOUT AT APPROX. 30 KNOTS PILOT EXPERIENCED A GUST FROM HIS LEFT WHICH RESULTED IN THE PILOT VEERING OFF THE RUNWAY ON THE NORTH SIDE. THE AIRCRAFT NOSE WHEEL THEN STUCK INTO THE SNOW BANK AND THE WIND LIFTED THE TAIL OF THE AIRCRAFT OVER END COMING TO A REST INVERTED. PILOT HAD NO NOTICEABLE INJURIES. THE AIRCRAFT DAMAGE CONSISTS OF BENT PROP TIPS AND SPINNER. DAMAGE TO BOTH THE RIGHT AND LEFT WINGS. RIGHT WING AFT SPAR BROKEN AND WRINKLED ON TOP. RIGHT AILERON BENT OVERLAPPING THE FLAP BY THREE INC                     HES. LEFT WING WRINKLED. TOP OF VERTICAL STABILIZER ANTI-COLLISION LIGHT BROKEN.

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.
