## Sequence of events

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

- Overrun, landing - roll
  - weather condition - rain (contributing factor)
  - in-flight planning/decision - improper, pilot in command (cause)
  - airspeed - excessive, pilot in command (cause)
  - brakes(normal) - attempted, pilot in command
  - airport facilities,runway/landing area condition - wet (contributing factor)
- On ground/water encounter with terrain/water, landing - roll
  - terrain condition - ditch

## Analysis

THE PLT REPORTED THAT THE ACFT TOUCHED DOWN ABOUT 700 FT DOWN THE 2700 FT SOD RWY. THE RWY WAS WET FROM RAIN AND BRAKING ACTION WAS NIL. THE PLT ELECTED TO STAY ON THE RWY AND CONTINUE BRAKING EFFORTS. THE ACFT SLID OFF THE RWY END INTO A DRAINAGE DITCH. THE PLT STATED THAT HE SHOULD HAVE PLANNED BETTER AND SET UP FOR A SHORT-FLD LDG, AND BEEN AWARE OF POSSIBLE REDUCED BRAKING ACTION DUE TO RWY CONDITIONS.

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.
