(-23) ON OCTOBER 22, 2000, CESSNA CE-172-P, N5226K, CONDUCTING A SIGHT SEEING TOUR WITHIN 25 MILES OF HALF MOON BAY ATTEMPTED TO LAND AT HALF MOON BAY. THE PIC WAS ADVISED BY AIRPORT 1 ABOUT A 18-20 KTS CROSSWIND CONDITION AT MIDFIELD. PIC ACKNOWLEDGED AND MADE TWO ATTEMPTS TO LAND BEFORE HIS FINAL APPROACH. ON HIS THIRD APPROACH THE A/C TOUCHED DOWN APPROX. MID-WAY DOWN THE RUNWAY. UPON TOUCHDOWN THE A/C ENCOUNTERED CROSSWIND CONDITIONS AND THE A/C VEERED TO THE LEFT AND DEPARTED THE RUNWAY. DEPARTURE CONTINUED UNTIL CONTACT WITH THE PARIMETER FENCE AND FINAL MOVEMENT CEASED UPON HITTING A DIRT MOUNT. DAMAGE INCLUDED THE FOLLOWING: FIREWALL BENT AND BUCKLED, AFT RIGHT WING SPAR BENT DOWNWARD. LEFT WING TIP APPROX. 2 FT. DENTED, TWISTED UP AND AFT. LEADING EDGE OF LEFT INBOARD WING DENTED.

(.4) ON OCTOBER 22, 2000, AT 1140 HOURS PACIFIC DAYLIGHT TIME, A CESSNA 172P, N5226K, OVERRAN THE RUNWAY DURING LANDING, AND COLLIDED WITH A FENCE AT THE HALF MOON BAY AIRPORT, HALF MOON BAY, CALIFORNIA. THE AIRPLANE SUSTAINED SUBSTANTIAL DAMAGE, AND THE CERTIFICATED COMMERCIAL PILOT AND ONE OF HIS TWO PASSENGERS RECEIVED MINOR INJURIES. THE SECOND PASSENGER WAS NOT INJURED. THE AIRPLANE OWNER, D.B.A. COAST FLIGHT, OPERATED THE SIGHTSEEING FLIGHT UNDER THE PROVISIONS OF 14 CFR PART 91. THE LOCAL FLIGHT HAD ORIGINATED FROM THE HALF MOON BAY AIRPORT ABOUT 1030. VISUAL METEOROLOGICAL CONDITIONS PREVAILED AT THE TIME, AND NO FLIGHT PLAN WAS FILED. THE PILOT REPORTED THAT AS HE INITIATED HIS APPROACH TO RUNWAY 30 HE NOTICED STRONG GUSTY WINDS AND LOW-LEVEL SHEAR CONDITIONS. TO COMPENSATE, HE INCREASED HIS APPROACH AIRSPEED AND LEFT THE FLAPS IN THEIR RETRACTED POSITION. WHILE CONTINUING OVER THE APPROACH END OF THE RUNWAY, HE ENCOUNTERED AN AREA WITH A HIGH SINK RATE. HE IMMEDIATELY ADDED FULL POWER TO STOP HIS DESCENT. WITH FULL POWER, AND WITH THE AIRPLANE'S NOSE ABOUT 5 DEGREES ABOVE THE HORIZON, THE AIRPLANE BEGAN TO CLIMB SLOWLY. AT THIS POINT, THE PILOT ENCOUNTERED A STRONG, GUSTING, RIGHT QUARTERING HEADWIND THAT LIFTED THE RIGHT WING AND RESULTED IN A LOSS OF ALTITUDE. IN RESPONSE, AS THE AIRPLANE TOUCHED DOWN BEYOND THE DEPARTURE END OF THE RUNWAY, THE CLOSED THE THROTTLE. THE AIRPLANE ROLLED THROUGH A FENCE BEFORE COMING TO A STOP. WINDS AT THE CLOSEST WEATHER REPORTING STATION SAN FRANCISCO INTERNATIONAL AIRPORT (SFO), WERE 360 AT 18 KNOTS GUSTING TO 22 KNOTS. ## 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.
