## Sequence of events

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

- In flight collision with terrain/water, takeoff - initial climb
  - aircraft handling - improper, pilot in command (contributing factor)
  - abort - delayed, pilot in command (cause)

## Analysis

THE PILOT-IN-COMMAND OF THE AMPHIBIOUS AIRPLANE APPLIED INADEQUATE TECHNIQUE DURING THE TAKEOFF ATTEMPT AND COMPOUNDED THE PROBLEM BY DELAYING ABORTING THE TAKEOFF. HE CHANGED HIS MIND TWICE BEFORE FLYING/SKIDDING INTO TREES. THE PILOT STATED THAT HE SHOULD HAVE RETRACTED FLAPS BEFORE REDUCING THROTTLE.
