## Sequence of events

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

- Overrun, landing - roll
  - weather condition - high density altitude (contributing factor)
  - proper touchdown point - exceeded, pilot in command (cause)
  - lack of familiarity with aircraft, pilot in command (cause)
  - distance - misjudged, pilot in command (cause)
  - inadequate transition/upgrade training, pilot in command (cause)
  - go-around - not performed, pilot in command (cause)
- On ground/water collision with object, landing - roll
  - object - tree(s) (contributing factor)

## Analysis

THE ACFT RAN OFF THE DEPARTURE END OF THE RWY AND COLLIDED WITH TREES DURING LANDING. THE DENSITY ALT AT THE ARPT WAS 8800 FT AT THE TIME OF THE ACCIDENT. THE LANDING RWY WAS 19 AND THE WIND WAS 270 DEGREES AT 3 KTS. THE ACFT LANDED ABOUT2500 FT DOWN THE 5000 FT RWY. AN FAA INSPECTOR NOTED SKID MARKS FROM BOTH TIRES STARTING 650 FT FROM THE RWYS END. THE PLT HAD ONLY 3.4 HOURS IN THIS ACFT OF WHICH 1 HOUR WAS A CHECKOUT RIDE AND 2.4 HOURS FOR THE CROSS-COUNTRY.

## Other investigations on N4581W (1)

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.
