Narrative:

While landing on the narrow runway, one wheel touched the grass. Since it had rained, the ground was very soft and the plane left the runway. Just before rolling out on the grass the plane entered a ditch. The ensuing propeller strike destroyed the propeller. To prevent a recurrence, more positive directional control needs to be maintained. Puddles on the runway were a contributing factor.

Original NASA ASRS Text

Title: BIPLANE LNDG ON NARROW RWY HAS ONE WHEEL TOUCH GRASS, EXITS RWY DUE SOFT, RAIN SOAKED EARTH. HITS DITCH, STRIKES PROP.

Narrative: WHILE LNDG ON THE NARROW RWY, ONE WHEEL TOUCHED THE GRASS. SINCE IT HAD RAINED, THE GND WAS VERY SOFT AND THE PLANE LEFT THE RWY. JUST BEFORE ROLLING OUT ON THE GRASS THE PLANE ENTERED A DITCH. THE ENSUING PROP STRIKE DESTROYED THE PROP. TO PREVENT A RECURRENCE, MORE POSITIVE DIRECTIONAL CTL NEEDS TO BE MAINTAINED. PUDDLES ON THE RWY WERE A CONTRIBUTING FACTOR.
