## Probable cause

The failure of the pilot to maintain compensation for wind conditions.  Factors to the accident were the crosswind condition and the presence of trees along the runway.

## Sequence of events

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

- Loss of control - in flight, landing - flare/touchdown
  - compensation for wind conditions - not maintained, pilot in command (cause)
  - weather condition - crosswind (contributing factor)
  - object - tree(s) (contributing factor)
- In flight collision with terrain/water, landing - flare/touchdown
- Nose gear collapsed, landing - flare/touchdown

## Analysis

According to the pilot's written statement, the pilot 'experienced [wind] shear on short final to runway 27...'  A weather report for a reporting station located 21 nautical miles and 253 degrees from the accident site reported winds from 200 degrees at 11 knots.  According to the 1999 Michigan Airport Directory, the runway that was used has several groupings of trees along both sides of the runway.  Post accident investigation revealed damage to the right wing, propeller, nose landing gear, and fuselage substructure.  Further examination revealed no pre-existing anomalies.

## Factual narrative

Visual meteorological conditions prevailed at the time of the accident.  The 14 CFR Part 91 flight was not operating on a flight plan.  The pilot reported no injuries to himself and his one passenger.  The flight originated at the Dupont-Lapeer Airport for a local flight at 1100 est.
