Narrative:

On sep/thu/00, at approximately XY15 pm, I landed in the stopway area, just short of the runway threshold. The landing was firm, but I did not consider it a hard landing. 1 of the 3 nurses I was carrying, said that it was the hardest landing that they had ever experienced. This statement was relayed through a mutual friend of one of the other line pilots 3 days after the flight. The only explanation I have that may have caused this firm and early touchdown was windshear. Although my intent was to touch down at the threshold, the airplane unexplainably came down earlier than I expected. The runway is surrounded by extremely rugged and high terrain and has associated turbulence and gusts. I believe that I carried enough speed to compensate for these conditions when on the final approach. The airplane, I might add, never showed any indications that it was slow or unstable throughout the final and touchdown phases of the flight. The winds at the time as reported by the AWOS-3 at XA00Z were 090 degrees/14 KTS gusting 18 KTS. Later, the winds were 090 degrees/15 KTS gusting 22 KTS. In addition, the unicom personnel took an AWOS-3 observation at the following times: at XA50Z the winds were 100 degrees/11 KTS gusting 15 KTS and at XA52Z the winds were 070 degrees/3 KTS gusting 14 KTS. During the hour while waiting for the medical crew to return from the hospital, the first officer and I noticed that the winds shifted a direction of 180 degrees 2 times. First, the winds were from the east, then the winds were from the west. When we departed, the winds were out of the east again. During these wind shifts, the winds were approximately 090 degrees/10 KTS gusting 15 KTS and 270 degrees/10 KTS gusting 15 KTS respectively. In retrospect, under similar conditions, I should have chosen to use more of the available useable runway.

Title: A LEAR 25 FLC LANDS SHORT OF RWY 9 DURING RPTED WINDSHEAR CONDITIONS AND IS LATER TOLD THAT THE PAX ONBOARD FELT IT WAS A HARD LNDG AT MMH, CA.

Narrative: ON SEP/THU/00, AT APPROX XY15 PM, I LANDED IN THE STOPWAY AREA, JUST SHORT OF THE RWY THRESHOLD. THE LNDG WAS FIRM, BUT I DID NOT CONSIDER IT A HARD LNDG. 1 OF THE 3 NURSES I WAS CARRYING, SAID THAT IT WAS THE HARDEST LNDG THAT THEY HAD EVER EXPERIENCED. THIS STATEMENT WAS RELAYED THROUGH A MUTUAL FRIEND OF ONE OF THE OTHER LINE PLTS 3 DAYS AFTER THE FLT. THE ONLY EXPLANATION I HAVE THAT MAY HAVE CAUSED THIS FIRM AND EARLY TOUCHDOWN WAS WINDSHEAR. ALTHOUGH MY INTENT WAS TO TOUCH DOWN AT THE THRESHOLD, THE AIRPLANE UNEXPLAINABLY CAME DOWN EARLIER THAN I EXPECTED. THE RWY IS SURROUNDED BY EXTREMELY RUGGED AND HIGH TERRAIN AND HAS ASSOCIATED TURB AND GUSTS. I BELIEVE THAT I CARRIED ENOUGH SPD TO COMPENSATE FOR THESE CONDITIONS WHEN ON THE FINAL APCH. THE AIRPLANE, I MIGHT ADD, NEVER SHOWED ANY INDICATIONS THAT IT WAS SLOW OR UNSTABLE THROUGHOUT THE FINAL AND TOUCHDOWN PHASES OF THE FLT. THE WINDS AT THE TIME AS RPTED BY THE AWOS-3 AT XA00Z WERE 090 DEGS/14 KTS GUSTING 18 KTS. LATER, THE WINDS WERE 090 DEGS/15 KTS GUSTING 22 KTS. IN ADDITION, THE UNICOM PERSONNEL TOOK AN AWOS-3 OBSERVATION AT THE FOLLOWING TIMES: AT XA50Z THE WINDS WERE 100 DEGS/11 KTS GUSTING 15 KTS AND AT XA52Z THE WINDS WERE 070 DEGS/3 KTS GUSTING 14 KTS. DURING THE HR WHILE WAITING FOR THE MEDICAL CREW TO RETURN FROM THE HOSPITAL, THE FO AND I NOTICED THAT THE WINDS SHIFTED A DIRECTION OF 180 DEGS 2 TIMES. FIRST, THE WINDS WERE FROM THE E, THEN THE WINDS WERE FROM THE W. WHEN WE DEPARTED, THE WINDS WERE OUT OF THE E AGAIN. DURING THESE WIND SHIFTS, THE WINDS WERE APPROX 090 DEGS/10 KTS GUSTING 15 KTS AND 270 DEGS/10 KTS GUSTING 15 KTS RESPECTIVELY. IN RETROSPECT, UNDER SIMILAR CONDITIONS, I SHOULD HAVE CHOSEN TO USE MORE OF THE AVAILABLE USEABLE RWY.
