## Probable cause

the failure of the pilot to maintain directional control.  Factors were the misjudged flare and improper recovery from the bounced landing by the pilot, and the ditch.

## Sequence of events

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

- Loss of control - on ground/water, landing
  - flare - misjudged, pilot in command (contributing factor)
  - recovery from bounced landing - improper, pilot in command (contributing factor)
  - directional control - not maintained, pilot in command (cause)
- Nose over, landing
  - terrain condition - ditch (contributing factor)

## Analysis

While landing, the airplane bounced. The pilot stated that he attempted to correct for the '...slight crosswind...' and subsequently departed the runway into the grass adjacent to the runway.  The pilot said that the aircraft 'slowed rapidly [and] went into [a] dip in [the] infield and flipped over.'  A postaccident examination of the aircraft revealed no preexisting anomalies.

## Factual narrative

On July 30, 1999, about 1700 central daylight time, a Cessna 180K, N4809E, piloted by a private pilot, sustained substantial damage during landing on runway 29 (3,900 feet by 75 feet, dry/asphalt), at the Shawano Municipal Airport, Shawano, Wisconsin.  Visual meteorological conditions prevailed at the time of the accident.  The personal flight was being conducted under the provisions of 14 CFR Part 91 and was not on a flight plan.  The pilot, who was the sole occupant, reported no injuries.  The flight had originated about 1630 from the Shawano Municipal Airport for a local flight.

In a written statement, the pilot said that he landed hard and the aircraft "...bounced and came back down."  The pilot stated that he attempted to correct for the "...slight crosswind..." and subsequently departed the runway into the grass adjacent to the runway.  The pilot said that the aircraft "slowed rapidly [and] went into [a] dip in [the] infield and flipped over."  The aircraft came to rest in an inverted position.

A postaccident examination of the aircraft revealed no preexisting anomalies.
