## Probable cause

The pilot's failure to maintain aircraft control.  A factor in the accident was the large wave.

## Sequence of events

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

- Nose over, takeoff - roll/run
  - terrain condition - large wave/swell (contributing factor)
  - aircraft control - not maintained, pilot in command (cause)

## Analysis

While performing a touch-and-go on a lake, at a speed of about 50 knots, the airplane passed through the wake of a motorboat.  The pilot attempted to abort the takeoff; however, the airplane nosed over, before re-floating upright on its pontoons.

## Factual narrative

On September 8, 2000, about 0925 Eastern Daylight Time, a Lake LA-4-200, N2594P, was substantially damaged during a touch and go landing on Lake Winnipesaukee, Laconia, New Hampshire.  The certificated private pilot was not injured.  Visual meteorological conditions prevailed and no flight plan was filed for the local flight conducted under 14 CFR Part 91.

According to the pilot, he over flew the lake at 500 feet for an intended landing.  The water conditions looked "good," and the pilot observed two boats that were about 1 mile from the area where he planned to land.  The airplane touched down on the lake and the pilot elected to perform a touch-and-go.  As the takeoff run began, at a speed of about 50 knots, the airplane passed through the wake of a motorboat.  The pilot attempted to abort the takeoff; however, the airplane nosed over, before re-floating upright on its pontoons.

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.
