## Sequence of events

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

- In flight collision with terrain/water, maneuvering
  - emergency procedure - simulated, pilot in command(cfi) (contributing factor)
  - precautionary landing - simulated, dual student (contributing factor)
  - weather condition - gusts (contributing factor)
  - supervision - inadequate, pilot in command(cfi) (cause)
- Main gear collapsed, maneuvering
  - landing gear,main gear attachment - overload (contributing factor)

## Analysis
