## Sequence of events

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

- Loss of engine power, takeoff - roll/run
  - engine assembly - undetermined (cause)
- In flight collision with terrain/water, takeoff - initial climb
  - object - tree(s)
  - aborted takeoff - delayed, pilot in command (cause)
  - lack of total experience, pilot in command (contributing factor)
  - weather condition - rain

## Analysis

THE PILOT STATED THAT HE FELT THE ENGINE DID NOT DEVELOP FULL POWER DURING TAKEOFF, POSSIBLY DUE TO FORMATION OF CARBURETOR ICE DURING RAIN SHOWERS. INSTEAD OF ABORTING, HE CONTINUED AND THE ACFT STRUCK TREES ON THE DEPARTURE.
