What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Landed long and fast. Overran runway. Came to rest in mobil home park destroying the aircraft. (-23) N1DK was established on the I.l.s. (instrument landing system) approach to runway 10 at the Allegheny County Airport (agc), west mifflin, PA, at about 3:45PM local time. The sole passenger, a Learjet and westwind pilot, noted the approach speed as being about 160 knots. Furthermore, the aircraft was observed by the passenger and tower personnel as having landed near the intersection of runway 31 leaving only about 3000 feet of runway for the landing. The aircraft failed to stop and overran the runway surface, coming to rest in a mobile home park at about 3:49 pm local time. The aircraft was flown to an excessively fast approach speed and touched down well beyond a normal landing point. (-23) N1DK was established on the I.l.s.

The sole passenger, a Learjet and westwind pilot, noted the approach speed as being about 160 knots. Furthermore, the aircraft was observed by the passenger and tower personnel as having landed near the intersection of r unway 31 leaving only about 3000 feet of runway for the landing. The aircraft failed to stop and overran the runway surface, coming to rest in a mobile home park at about 3:49 pm local time. The aircraft was flown at an excessively fast approach speed and touched down well beyond a normal landing point. (.4)the pilot initiated an ILS approach with rain and fog. Approach flaps were maintained until the runway was sighted, and then landing flaps were set. The airplane landed long, overran the runway, struck the ILS localizer antenna on the departure end of the runway, and came to rest at the edge of a mobile home park. The airplane and two mobile homes were destroyed by fire. Vref had been computed at 110 KTS. The PIC reported a speed on final of 130 KTS, while the SIC said it was 140 KTS. Radar data revealed a 160 knots ground speed from the outer marker until 1.8 miles from touchdown. The airplane passed the control tower, airborne, with 2,500 feet of runway remaining on the 6,500 foot long runway. Performance data revealed that the airplane would require about 2,509 feet on a dry runway, and 5,520 feet on a wet runway. The airplane was not equipped with thrust reversers or anti-skid brakes. The PIC was the company president, and the SIC was a recent hire who had flown with the PIC three previous times. The PIC was qualified for single-pilot operations in the airplane, and had been trained to fly stabilized approaches.
As the FAA filed it
LANDED LONG AND FAST. OVERRAN RUNWAY. CAME TO REST IN MOBIL HOME PARK DESTROYING THE AIRCRAFT. (-23) N1DK WAS ESTABLISHED ON THE I.L.S. (INSTRUMENT LANDING SYSTEM) APPROACH TO RUNWAY 10 AT THE ALLEGHENY COUNTY AIRPORT (AGC), WEST MIFFLIN, PA, AT ABOUT 3:45PM LOCAL TIME. THE SOLE PASSENGER, A LEARJET AND WESTWIND PILOT, NOTED THE APPROACH SPEED AS BEING ABOUT 160 KNOTS. FURTHERMORE, THE AIRCRAFT WAS OBSERVED BY THE PASSENGER AND TOWER PERSONNEL AS HAVING LANDED NEAR THE INTERSECTION OF RUNWAY 31 LEAVING ONLY ABOUT 3000 FEET OF RUNWAY FOR THE LANDING. THE AIRCRAFT FAILED TO STOP AND OVERRAN THE RUNWAY SURFACE, COMING TO REST IN A MOBILE HOME PARK AT ABOUT 3:49 PM LOCAL TIME. THE AIRCRAFT WAS FLOWN TO AN EXCESSIVELY FAST APPROACH SPEED AND TOUCHED DOWN WELL BEYOND A NORMAL LANDING POINT. (-23) N1DK WAS ESTABLISHED ON THE I.L.S.

THE AIRPLANE LANDED LONG, OVERRAN THE RUNWAY, STRUCK THE ILS LOCALIZER ANTENNA ON THE DEPARTURE END OF THE RUNWAY, AND CAME TO REST AT THE EDGE OF A MOBILE HOME PARK. THE AIRPLANE AND TWO MOBILE HOMES WERE DESTROYED BY FIRE. VREF HAD BEEN COMPUTED AT 110 KTS. THE PIC REPORTED A SPEED ON FINAL OF 130 KTS, WHILE THE SIC SAID IT WAS 140 KTS. RADAR DATA REVEALED A 160 KNOTS GROUND SPEED FROM THE OUTER MARKER UNTIL 1.8 MILES FROM TOUCHDOWN. THE AIRPLANE PASSED THE CONTROL TOWER, AIRBORNE, WITH 2,500 FEET OF RUNWAY REMAINING ON THE 6,500 FOOT LONG RUNWAY. PERFORMANCE DATA REVEALED THAT THE AIRPLANE WOULD REQUIRE ABOUT 2,509 FEET ON A DRY RUNWAY, AND 5,520 FEET ON A WET RUNWAY. THE AIRPLANE WAS NOT EQUIPPED WITH THRUST REVERSERS OR ANTI-SKID BRAKES. THE PIC WAS THE COMPANY PRESIDENT, AND THE SIC WAS A RECENT HIRE WHO HAD FLOWN WITH THE PIC THREE PREVIOUS TIMES. THE PIC WAS QUALIFIED FOR SINGLE-PILOT OPERATIONS IN THE AIRPLANE, AND HAD BEEN TRAINED TO FLY STABILIZED APPROACHES.
