## Probable cause

The flight instructors failure to maintain clearance from trees while maneuvering.  Contributing factors were the downdraft weather condition, and the tree.

## Sequence of events

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

- In flight collision with object, maneuvering
  - altitude/clearance - not maintained, pilot in command(cfi) (cause)
  - object - tree(s) (contributing factor)
  - weather condition - downdraft (contributing factor)
- In flight collision with terrain/water, descent - uncontrolled
  - terrain condition - mountainous/hilly

## Analysis

The flight instructor said that he had the student under the hood and was giving him headings to follow.  He said that as they approached the mountains the aircraft began to lose altitude.  The flight instructor said that he took control of the airplane and attempted to maneuver the airplane out of the downdraft.  He said that even with full power, the aircraft settled and impacted a tree.  He said the airplane "spun around 180 degrees and landed in a small stream [approximately 2 inches deep] on its landing gear."  The flight instructor said that the airplane was destroyed.
