## Probable cause

FAILURE OF THE PILOT TO EXTEND THE GEAR, WHICH RESULTED IN AN INADVERTENT WHEELS-UP LANDING.

## Sequence of events

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

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

## Analysis

THE PILOT/AIRCRAFT OWNER FLEW THE AIRCRAFT FROM ITS HOME BASE TO A LOCAL AIRPORT (8 MI SOUTHWEST) TO HAVE SOME AVIONICS WORK ACCOMPLISHED. DURING THE LANDING, THE AIRCRAFT TOUCHED DOWN ON THE RUNWAY WITH THE GEAR RETRACTED. A POST-ACCIDENT EXAM OF THE COCKPIT REVEALED THE LANDING GEAR HANDLE WAS IN THE 'UP' POSITION.  THE PILOT INDICATED THAT HE COULD NOT RECALL EXTENDING THE GEAR PRIOR TO TOUCHDOWN.
