## Probable cause

FAILURE TO THE PILOT TO ASSURE GEAR EXTENSION. FACTORS RELATED TO THE ACCIDENT WERE THE ELECTRICAL FAILURE DUE TO A SEIZED ALTERNATOR AND DIVERTED ATTENTION BY THE PILOT.

## Sequence of events

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

- Main gear collapsed, landing - flare/touchdown
  - electrical system,alternator - seized (contributing factor)
  - weather condition - crosswind
  - weather condition - gusts
  - gear extension - not attained, pilot in command (cause)
  - diverted attention, pilot in command (contributing factor)
- On ground/water encounter with terrain/water, landing - flare/touchdown

## Analysis

THE PILOT SAID THAT HE WAS GIVEN A GREEN LIGHT FOR LANDING FROM THE CONTROL TOWER DUE TO ELECTRICAL FAILURE DURING THE LANDING, THE MAIN GEAR COLLAPSED. POST ACCIDENT INVESTIGATION REVEALED THE ALTERNATOR TO BE INOPERATIVE DUE TO A FROZEN PULLEY/SHAFT.
