## Probable cause

THE FAILURE OF THE PILOT TO CONDUCT A PROPER PRE-FLIGHT INSPECTION AND REMOVE THE TAIL MOORING FROM THE FLOAT PLANE. CONTRIBUTING TO THE ACCIDENT WAS THE PILOT'S OVER CONFIDENCE IN HIS PERSONAL ABILITY.

## Sequence of events

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

- Loss of control - in flight, takeoff - initial climb
  - aircraft preflight - improper, pilot in command (cause)
  - misc eqpt/furnishings - not removed (cause)
  - checklist - not followed, pilot in command (cause)
  - tie down - not corrected, pilot in command (cause)
  - climb - not attained, pilot in command (cause)
- On ground/water collision with object, takeoff - roll/run
  - object - tree(s)
  - terrain condition - dirt bank/rising embankment

## Analysis

THE ACCIDENT REPORT SUBMITTED BY THE FLYING CLUB CHIEF INDICATED THAT THE PILOT DID NOT RELEASE THE TAIL TIEDOWN DURING HIS PREFLIGHT INSPECTION. IT WAS ATTACHED TO A 4X4 POST IN A CONCRETE WEIGHT. DURING THE ATTEMPTED TAKEOFF THE AIRPLANE WOULD NOT GET ON STEP. THE TAKEOFF WAS ABORTED. A SECOND TAKEOFF WAS ATTEMPTED FROM THE MIDDLE OF THE LAKE. DURING THE TAKEOFF THE NOSE BEGAN TO PITCH UP APPROACHING A STALL. THE PILOT PUSHED THE YOKE FORWARD & THE AIRPLANE SETTLED BACK ONTO THE WATER JUST PRIOR TO IMPACT WITH THE LAKE'S DEPARTURE END SHORELINE.
