## Probable cause

THE PILOT'S MISJUDGED LANDING POINT AND THE EXCESSIVE AIRSPEED. A FACTOR WAS THE WET GRASS STRIP

## Sequence of events

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

- Overrun, landing - roll
  - proper touchdown point - misjudged, pilot in command (cause)
  - airspeed - excessive, pilot in command (cause)
  - terrain condition - grass
  - terrain condition - wet (contributing factor)
- Nose over, landing - roll

## Analysis

THE PILOT REPORTED HE LANDED HOT AND LONG. HE APPLIED THE BRAKES, HOWEVER, THE AIRPLANE SKIDDED ON THE WET TURF UNTIL IT REACHED A PAVED AREA WHERE IT NOSED OVER TO THE INVERTED POSITION.

## Factual narrative

On April 9, 1993, at approximately 1810 central daylight time (CDT) a Cessna 150J, N5517G, was substantially damaged during landing near Waterproof, Louisiana. Weather for the local flight was visual meteorological conditions. The private pilot, who was also the owner, was not injured.

During an interview, conducted by a Federal Aviation Administration inspector, the pilot reported that after landing "long and hot" he applied the brakes and the airplane skidded on the wet turf. When the airplane reached the end of the turf strip it struck a paved area with the main landing gear, with the brakes still applied, and the airplane nosed over to the inverted position.
