## Probable cause

IMPROPER PLANNING/DECISION BY THE PILOT, WHICH RESULTED IN HIS FAILURE (OR INABILITY) TO ALIGN THE ACFT WITH THE RUNWAY DURING THE LANDING.  THE LOW CEILING, TAILWIND, AND DITCH WERE RELATED FACTORS.

## Sequence of events

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

- On ground/water collision with object, landing - roll
  - planning/decision - improper, pilot in command (cause)
  - weather condition - low ceiling (contributing factor)
  - weather condition - tailwind (contributing factor)
  - terrain condition - ditch (contributing factor)
  - proper alignment - not attained, pilot in command (cause)

## Analysis

THE PLT FLEW TO ANOTHER ARPT & MADE TOUCH & GO LNDGS. HE RPRTD THAT WHEN HE RETURNED, THERE WAS A LOW CEILING, BUT HE COULD SEE THE ARPT FROM SVRL MILES AWAY. DURING AN ATTEMPT TO LAND ON RWY 17, THE ACFT TOUCHED DOWN IN A GRASS COVERED DRAINAGE DITCH TO THE RIGHT OF THE RWY. THE PLT WAS UNABLE TO STEER THE ACFT OUT OF THE DITCH. SUBSEQUENTLY, IT HIT A CULVERT & WAS EXTENSIVELY DMGD. A WITNESS ESTIMATED THE CEILING WAS 300' & THE WIND WAS FROM 360 DEG AT 8 KTS.
