Narrative:

Approach into payson municipal airport (pan) for runway 24, 5157 ft and 5500 ft long. Listened to pan AWOS-3 (119.325) for local information. Reported blowing and gusting to 15 KTS, and a density altitude of 6100 ft. I entered a 45 degree right downwind pattern and visually observed winds blowing directly down the runway with an occasional shift to the south. Decided to use 2 notches of flaps (25 degrees) and an 85 mph approach. Over the number (100 ft AGL) the aircraft was greeted with severe turbulence and I called an aborted landing. As I applied full power, we were hit by windshear that brought us almost into contact with the north side of the runway, outside of the lights. The turbulence was severe enough to require complete rudder and yoke inputs. As we flew past the center point of the runway, although still headed generally on a 240 degree compass heading, the aircraft yaw was almost 90 degrees south. I continued to fly the aircraft with the flaps in the 25 degree position. As the aircraft continued down the runway, we were still experiencing a significant down force and it was now coupled with a direct left crosswind, which made straightening the aircraft for a landing difficult and climbing out impossible. As we were shadowed by a group of trees, I made the decision to land on the runway overshoot. I applied right rudder, pulled the power off, dropped the mains on the ground, went to flaps 0 degrees, kept the yoke in my chest and applied braking (hand lever). The aircraft rolled to a controled stop in the weeds with no damage. We exited the aircraft of our own power after turning off the ignition, mains and fuel selector. The entire time this was going on, I remembered what my flight instructor told me: 'no matter what is in front of you, no matter what is going on, just keep flying the airplane.' this was my mantra during this landing.

Title: PIPER PA28 PVT PLT LOST ACFT CTL DURING LNDG IN GUSTY XWIND CONDITION RESULTING IN GOING OFF THE END OF THE RWY INTO WEEDS. THERE WAS NO ACFT OR PERSONAL INJURIES.

Narrative: APCH INTO PAYSON MUNICIPAL ARPT (PAN) FOR RWY 24, 5157 FT AND 5500 FT LONG. LISTENED TO PAN AWOS-3 (119.325) FOR LCL INFO. RPTED BLOWING AND GUSTING TO 15 KTS, AND A DENSITY ALT OF 6100 FT. I ENTERED A 45 DEG R DOWNWIND PATTERN AND VISUALLY OBSERVED WINDS BLOWING DIRECTLY DOWN THE RWY WITH AN OCCASIONAL SHIFT TO THE S. DECIDED TO USE 2 NOTCHES OF FLAPS (25 DEGS) AND AN 85 MPH APCH. OVER THE NUMBER (100 FT AGL) THE ACFT WAS GREETED WITH SEVERE TURB AND I CALLED AN ABORTED LNDG. AS I APPLIED FULL PWR, WE WERE HIT BY WINDSHEAR THAT BROUGHT US ALMOST INTO CONTACT WITH THE N SIDE OF THE RWY, OUTSIDE OF THE LIGHTS. THE TURB WAS SEVERE ENOUGH TO REQUIRE COMPLETE RUDDER AND YOKE INPUTS. AS WE FLEW PAST THE CTR POINT OF THE RWY, ALTHOUGH STILL HEADED GENERALLY ON A 240 DEG COMPASS HDG, THE ACFT YAW WAS ALMOST 90 DEGS S. I CONTINUED TO FLY THE ACFT WITH THE FLAPS IN THE 25 DEG POS. AS THE ACFT CONTINUED DOWN THE RWY, WE WERE STILL EXPERIENCING A SIGNIFICANT DOWN FORCE AND IT WAS NOW COUPLED WITH A DIRECT L XWIND, WHICH MADE STRAIGHTENING THE ACFT FOR A LNDG DIFFICULT AND CLBING OUT IMPOSSIBLE. AS WE WERE SHADOWED BY A GROUP OF TREES, I MADE THE DECISION TO LAND ON THE RWY OVERSHOOT. I APPLIED R RUDDER, PULLED THE PWR OFF, DROPPED THE MAINS ON THE GND, WENT TO FLAPS 0 DEGS, KEPT THE YOKE IN MY CHEST AND APPLIED BRAKING (HAND LEVER). THE ACFT ROLLED TO A CTLED STOP IN THE WEEDS WITH NO DAMAGE. WE EXITED THE ACFT OF OUR OWN PWR AFTER TURNING OFF THE IGNITION, MAINS AND FUEL SELECTOR. THE ENTIRE TIME THIS WAS GOING ON, I REMEMBERED WHAT MY FLT INSTRUCTOR TOLD ME: 'NO MATTER WHAT IS IN FRONT OF YOU, NO MATTER WHAT IS GOING ON, JUST KEEP FLYING THE AIRPLANE.' THIS WAS MY MANTRA DURING THIS LNDG.
