## Probable cause

THE PILOT'S MISJUDGMENT OF DISTANCE (RUNWAY REMAINING) AFTER THE AIRCRAFT TOUCHED DOWN AND/OR HIS FAILURE TO GO-AROUND WHEN THERE WAS STILL SUFFICIENT SPEED TO DO SO.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Overrun, landing - roll
  - distance - misjudged, pilot in command (cause)
  - go-around - not performed, pilot in command (cause)
- On ground/water encounter with terrain/water, landing
  - terrain condition - roadway/highway

## Analysis

THE PILOT REPORTED THAT HE ENTERED THE TRAFFIC PATTERN WITH AN AIRSPEED OF 90 KNOTS. HE STATED HE EXTENDED THE GEAR AND 20 DEGREES OF FLAPS, THEN STARTED HIS TURN TO BASE. HE SAID THAT HE REDUCED HIS SPEED TO 80 KNOTS, AND ON FINAL, HE APPLIED FULL FLAPS AND REDUCED SPEED TO 70 KNOTS. HE REPORTED THAT DURING THE LANDING ROLL, HE APPLIED BRAKES, BUT THE AIRPLANE RAN OFF THE END OF THE RUNWAY, WENT OFF AN EMBANKMENT, AND COLLIDED WITH A ROAD.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Accident 19910120055949A](https://openairdocs.org/incident/19910120055949A), Jan 20, 1991: Mooney M20K, Fredericksburg, VA, Substantial damage. Landed long. Ran off departure end of runway and slid off an embankment. Blamed not braking timely on runway.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
