Narrative:

Since the WX was very clear, I used the opportunity to check both GS receivers after being cleared for the ILS runway 28R approach and then cleared to land by the tower. Touchdown was at a speed of approximately 95 mph. My usual technique of lifting the nose high into the air, after landing, to slow the plane down without riding the brakes too hard was used. After holding this position for what I felt was about 2000 ft, the nose was lowered and the brakes were applied. It was then I discovered that the runway 10L numbers on the pavement were but a few ft away. Maximum braking did not stop the plane on the runway, and it came to a stop with the front wheel about 35 ft off the end of the runway in the dirt. The front tire and wheel were ruined, however there appears to be no other damage. On the plan view of the commercial approach plate, which I was using, the length of runway 28R was 4577 ft. Airport information sheet, which I had also reviewed during the flight states 'long runway 4500 ft.' what I failed to take into consideration was that under 'additional runway information' on the plan view, in the fine print it explains that landing beyond the threshold there is 3401 ft and beyond the GS there is only 2368 ft. This means that there was about 2200 ft less runway available than I thought there was. Leading to my confusion about the amount of runway for rollout, is the fact that on government charts (which I have used for many yrs) this information is listed on the plan view chart in the upper r-hand corner as a note. On the charts, the amount of runway for rollout is listed in a chart below the plan view under 'additional runway information.' prior to this incident, I felt that I had acquainted myself with all of the differences between commercial charts and government charts. Before using the charts again, I shall intensely study the differences. This incident happened at night.

Title: AC680 PLT, FAILING TO ACCOUNT FOR THE REDUCED RWY REMAINING AFTER THE GS TOUCHDOWN POINT, HAS A RWY EXCURSION AT MGY.

Narrative: SINCE THE WX WAS VERY CLR, I USED THE OPPORTUNITY TO CHK BOTH GS RECEIVERS AFTER BEING CLRED FOR THE ILS RWY 28R APCH AND THEN CLRED TO LAND BY THE TWR. TOUCHDOWN WAS AT A SPD OF APPROX 95 MPH. MY USUAL TECHNIQUE OF LIFTING THE NOSE HIGH INTO THE AIR, AFTER LNDG, TO SLOW THE PLANE DOWN WITHOUT RIDING THE BRAKES TOO HARD WAS USED. AFTER HOLDING THIS POS FOR WHAT I FELT WAS ABOUT 2000 FT, THE NOSE WAS LOWERED AND THE BRAKES WERE APPLIED. IT WAS THEN I DISCOVERED THAT THE RWY 10L NUMBERS ON THE PAVEMENT WERE BUT A FEW FT AWAY. MAX BRAKING DID NOT STOP THE PLANE ON THE RWY, AND IT CAME TO A STOP WITH THE FRONT WHEEL ABOUT 35 FT OFF THE END OF THE RWY IN THE DIRT. THE FRONT TIRE AND WHEEL WERE RUINED, HOWEVER THERE APPEARS TO BE NO OTHER DAMAGE. ON THE PLAN VIEW OF THE COMMERCIAL APCH PLATE, WHICH I WAS USING, THE LENGTH OF RWY 28R WAS 4577 FT. ARPT INFO SHEET, WHICH I HAD ALSO REVIEWED DURING THE FLT STATES 'LONG RWY 4500 FT.' WHAT I FAILED TO TAKE INTO CONSIDERATION WAS THAT UNDER 'ADDITIONAL RWY INFO' ON THE PLAN VIEW, IN THE FINE PRINT IT EXPLAINS THAT LNDG BEYOND THE THRESHOLD THERE IS 3401 FT AND BEYOND THE GS THERE IS ONLY 2368 FT. THIS MEANS THAT THERE WAS ABOUT 2200 FT LESS RWY AVAILABLE THAN I THOUGHT THERE WAS. LEADING TO MY CONFUSION ABOUT THE AMOUNT OF RWY FOR ROLLOUT, IS THE FACT THAT ON GOV CHARTS (WHICH I HAVE USED FOR MANY YRS) THIS INFO IS LISTED ON THE PLAN VIEW CHART IN THE UPPER R-HAND CORNER AS A NOTE. ON THE CHARTS, THE AMOUNT OF RWY FOR ROLLOUT IS LISTED IN A CHART BELOW THE PLAN VIEW UNDER 'ADDITIONAL RWY INFO.' PRIOR TO THIS INCIDENT, I FELT THAT I HAD ACQUAINTED MYSELF WITH ALL OF THE DIFFERENCES BTWN COMMERCIAL CHARTS AND GOV CHARTS. BEFORE USING THE CHARTS AGAIN, I SHALL INTENSELY STUDY THE DIFFERENCES. THIS INCIDENT HAPPENED AT NIGHT.
