## Sequence of events

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

- On ground/water encounter with terrain/water, landing - roll
  - gear retraction - inadvertent, pilot in command (contributing factor)
  - checklist - not followed, pilot in command (cause)
  - terrain condition - runway (contributing factor)

## Analysis

THE PIC RPTD GEAR FAILURE AND GEAR WARNING HORN ABOUT 5 TO 10 SECONDS INTO THE LANDING ROLL. THE PIC RPTD 3 IN THE GREEN BEFORE TOUCHDOWN TO THE RWY. SUBSEQUENT INSPECTION OF THE LANDING GEAR SHOWED NO MECHANICAL OR OTHER DEFICIENCY. INADVERTENT MOVEMENT OF THE LANDING GEAR SWITCH PRIOR TO THE SWITCH ENGAGEMENT WOULD CYCLE THE LANDING GEAR RETRACTION SEQUENCE. GEAR RETRACTION AND EXTENSION TESTS PERFORMED ON THE ACFT SUBSEQUENT TO THE ACCIDENT FAILED TO DISCLOSE A PBLM.
