## Probable cause

Exceeding the airplane's maximum demonstrated crosswind component during the takeoff roll.  A contributing factor was the crosswind.

## Sequence of events

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

- Loss of control - on ground/water, takeoff - roll/run
  - crosswind component - exceeded, pilot in command (cause)
  - weather condition - crosswind (contributing factor)
- On ground/water encounter with terrain/water, takeoff - roll/run
  - airport facilities,runway/landing area condition - runway
- Nose down, takeoff - roll/run

## Analysis

According to the pilot, he was taking off on runway 02. The airplane weathervaned to the left and the right wing tip contacted the runway.  The airplane nosed over and the propeller struck the runway.  The right wing rear spar and aileron were bent, and the engine cowling was buckled. SAF wind was reportedly from 320 degrees at 11 knots.   An examination of the airplane's systems conducted by the FAA revealed no anomalies.  The Pilot's Operating Handbook (POH) for the 1960 Cessna 180C does not give a maximum demonstrated crosswind component.  However, the 1977 Cessna 180K POH lists the maximum demonstrated crosswind component as 12 knots.  The computed crosswind component at the time of the accident was 13 knots (headwind component 8 knots).
