AN LGT ACR ACFT RAN OFF THE END OF THE RWY AFTER A LONG TOUCHDOWN.

Narrative

DURING THE APCH INTO JACKSON HOLE; THE ACFT WAS SET UP TO LAND S ON RWY 18 AND TO THE L OF MOOSE LODGE AND ITS HIGHWAY. THE WX WAS CLR WITH WINDS AT 240/8 AND OUTSIDE AIR TEMP 71 DEGS F. THE RWY LENGTH WAS 6299 FT AND FIELD ELEVATION WAS 6445 MSL. THE ILS WAS TUNED FOR THIS APCH. SOME ADJUSTMENTS WERE MADE TO THE AIRSPD AS ALWAYS BECAUSE THE WINDS MOVE AROUND. THE APCH WAS NORMAL UNTIL THE ACFT WAS BELOW 50 FT. THE PLAN TOUCHDOWN POINT WAS 1000 FT; AND THE ACFT DELAYED ITS TOUCHDOWN MAYBE AS MUCH AS 2000 FT MORE THAN 1000 FT. ALL THIS TOOK PLACE UNDER 50 FT. AT ABOUT 30-20 FT AND MAYBE LOWER THAN THE 30-20 FT. WHEN THE ACFT STOPPED IT WAS OFF THE RWY BY 150 FT. IT WAS NOT KNOWN THAT ALL THAT RWY WAS USED IN THE FLARE. ON THE WALKAROUND AFTER THE AIRPLANE STOPPED; THE BRAKES WERE NOT HOT AND THE TIRES WERE NOT FLAT. AUTO BRAKES AND SPOILERS WERE USED AND MANUAL BRAKES WERE USED AFTER THE NOSE WHEEL TOUCHDOWN. MANUAL BRAKES WERE USED IN ORDER TO GET THE BEST BRAKING (AFTER NOSE WHEEL DOWN). #4 BRAKES WERE USED FIRST FOR THE AUTO BRAKES SETTING. THIS WAS AN LGT AND THE LNDG PRIOR TO THIS WAS DONE N A WDB ACFT. BOTH OF THESE AIRPLANES LAND AND FLARE DIFFERENTLY. IT MAY HAVE BEEN A GOOD WDB LNDG. 2 RWY LIGHTS WERE HIT AND A COUPLE OF TIRES WERE OUT. IT WAS UNKNOWN IF A BRAKE WAS CHANGED. NO PAX WERE HARMED. THE ACFT WAS FLOWN BY THE CAPT. MANUAL MAX BRAKING MAY NOT BE THAT EFFECTIVE.
