Probable cause

The pilot's failure to align the airplane with the runway during landing.

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

In flight collision with terrain/waterLanding - flare/touchdown
Terrain condition - high vegetation
Proper alignment - not attainedPilot in commandCause
Directional control - not maintainedPilot in command
On ground/water encounter with terrain/waterLanding - flare/touchdown
Terrain condition - ditch

Analysis

During landing the left wing contacted tall weeds on the edge of the runway. This resulted in a loss of directional control; the airplane subsequently contacted the ground not properly aligned and slid across a ditch. The airplane came to rest off the left side of the runway facing opposite the landing direction.
