NTSB narrative
The pilot flew the airplane on final approach above reference speed, landed long, overran the runway, and collided with airplanes in a tie down area. During the descent from 8,000 feet, and within 13 miles of the airport, the airplane reached speeds over 300 knots and attained descent rates in excess of 4,000 feet per minute. At 1.5 miles from the runway and 700 feet above the airport elevation, the airplane was descending at 3,000 feet per minute and flying over 200 knots. The reference speed was 138 knots with flaps 20 during the approach and 125 knots for landing. Company policy required the pilot to maintain speed within 10 knots of reference speed. Neither aircrew member considered a go around. The aircrew did not provide a safety briefing to the passenger. After the airplane came to rest, the aircrew evacuated the airplane prior to off-loading their passenger.
Probable cause
The pilot performed inadequate in flight planning and decided to continue the approach and landing with excessive airspeed. The pilot failed to follow company directives, which required a go around under the encountered flight conditions. This led to a long landing, resulting in an overrun and collision with parked airplanes.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
