## Probable cause

THE PILOT'S FAILURE TO MAINTAIN A PROPER CLIMB GRADIENT AND RATE AS A RESULT OF HIS INADEQUATE COMPENSATION FOR WIND CONDITIONS.

## Sequence of events

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

- In flight collision with terrain/water, climb - to cruise
  - terrain condition - mountainous/hilly
  - object - tree(s)
  - proper climb rate - not maintained, pilot in command (cause)
  - weather condition - tailwind (contributing factor)
  - compensation for wind conditions - inadequate, pilot in command (cause)

## Analysis

THE PILOT OF THE CESSNA 180 FLOATPLANE STATED THAT HE MADE A POWER REDUCTION AFTER TAKEOFF FOR NOISE ABATEMENT REASONS, AFTER CLIMBING TO ABOUT 40 FEET.  HE CONTINUED TO CLIMB TO ABOUT 50 FEET AFTER TURNING CROSSWIND.  HE STATED THAT WHEN HE TURNED EAST (DOWNWIND) TO FLY THROUGH THE CHANNEL, HE ADDED FULL POWER, BUT THE AIRCRAFT CONTINUED TO SLIP TOWARDS THE RIGHT SIDE OF THE CHANNEL AND IT ENDED UP CRASHING INTO THE TREES ABOUT FIFTY FEET FROM SHORE.

## Other investigations on N2601Y (1)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
