## Probable cause

FAILURE OF THE PILOT TO EXTEND THE LANDING GEAR. A FACTOR IN THE ACCIDENT WAS THE PILOT'S FAILURE TO USE THE CHECKLIST.

## Sequence of events

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

- Gear not extended, landing - flare/touchdown
  - wheels up landing - inadvertent, pilot in command
  - checklist - not used, pilot in command (contributing factor)
  - gear extension - not performed, pilot in command (cause)

## Analysis

THE PILOT SAID THAT DURING FINAL APPROACH, AND NEARING STALL SPEED, HE HEARD AN AUDIBLE HORN. HE INTERPRETED IT AS THE STALL WARNING HORN, AND CONTINUED HIS LANDING APPROACH, CONSEQUENTLY LANDING GEAR UP. THE ACFT SLID TO STOP ON THE RUNWAY SUSTAINING SUBSTANTIAL FUSELAGE AND PROPELLER DAMAGE. THE LANDING GEAR FUNCTIONED NORMALLY IN ALL PHASES DURING POST ACCIDENT INVESTIGATION. THE PILOT SAID HE INADVERTENTLY FORGOT TO LOWER THE LANDING GEAR.
