## Probable cause

PILOT-IN-COMMAND'S FAILURE TO PROPERLY CALCULATE THE AIRPLANE'S TAKEOFF PERFORMANCE AND THE EFFECT OF THE CROSSWIND.

## Sequence of events

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

- In flight collision with object, takeoff - initial climb
  - object - tree(s)
  - weather condition - crosswind (contributing factor)
  - aircraft performance,climb capability - exceeded (cause)
  - preflight planning/preparation - inadequate, pilot in command (cause)

## Analysis

THE PILOT-IN-COMMAND WAS TAKING OFF FROM AN 800 FOOT STRIP WITH A 15 TO 20 KNOT CROSS WIND. HE STATED THAT THE AIRPLANE LIFTED OFF AND CLIMBED TO TEN FEET ABOVE THE GROUND. THE AIRPLANE THEN STRUCK THREE TREES AND LANDED IN THE OCEAN.

## Other investigations on N2556C (2)

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.
