## Probable cause

The pilot's failure to maintain aircraft control which resulted in the aircraft porpoising during the landing.  A factor was the wind gusts.

## Sequence of events

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

- Hard landing, landing - flare/touchdown
  - aircraft control - not maintained, pilot in command (cause)
  - porpoise/pilot-induced oscillation - inadvertent, pilot in command (cause)
- Loss of control - on ground/water, landing - roll
  - landing gear - failure,partial
  - weather condition - gusts (contributing factor)

## Analysis

While attempting to land in variable wind conditions, with gusts to about 15 knots, the pilot inadvertently allowed the aircraft to porpoise. During that sequence, the nose gear hit the runway hard a number of times, and ultimately sustained damage that made the aircraft hard to control. The pilot then lost control of the aircraft, which departed the side of the runway.

## Factual narrative

While attempting to land in variable wind conditions, with gusts to about 15 knots, the pilot inadvertently allowed the aircraft to porpoise. During that sequence, the nose gear hit the runway hard a number of times, and ultimately sustained damage that made the aircraft hard to control. The pilot then lost control of the aircraft, which departed the side of the runway. A post-event inspection determined that the aircraft had sustained substantial damage.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
