## Sequence of events

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

- Airframe/component/system failure/malfunction, cruise - normal
  - electrical system,battery - failure,total (contributing factor)
  - electrical system,battery - exhaustion (contributing factor)
- Complete gear collapsed, landing - roll
  - precautionary landing - performed, pilot in command
  - emergency procedure - improper, pilot in command (cause)
  - gear down and locked - not attained, pilot in command (cause)

## Analysis

AFTER THE AIRCRAFT EXPERIENCED A COMPLETE ELECTRICAL FAILURE THE GEAR WAS EXTENDED MANUALLY AND A PRECAUTIONARY LANDING WAS MADE. ON ROLL OUT THE LANDING GEAR COLLAPSED. SUBSEQUENT INVESTIGATION REVEALED THAT 10 TURNS REMAINED ON THE MANUAL GEAR EXTENSION CRANK TO PLACE THE LANDING GEAR IN THE DOWN AND LOCKED POSITION. NO MECHANICAL PROBLEM COULD BE FOUND TO ATTRIBUTE TO THE LOSS OF ELECTRICAL POWER, OTHER THAN A LOW BATTERY CONDITION AS THE ENTIRE ELECTRICAL SYSTEM FUNCTIONED NORMALLY. POSITION OF THE BATTERY SWITCH AND THE LEFT AND RIGHT ALTERNATOR SWITCHES AT THE TIME OF THE ACCIDENT COULD NOT BE VERIFIED.
