## Probable cause

INADEQUATE PREFLIGHT BRIEFING AND INADVERTENT STALL MUSH DURING NORMAL CRUISE FLIGHT AFTER ENCOUNTERING TURBULENCE NEAR THE DESTINATION.

## Sequence of events

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

- In flight encounter with weather, cruise - normal
  - preflight briefing service - information insufficient, pilot in command (cause)
  - weather condition - turbulence
- Loss of control - in flight, cruise - normal
  - stall/mush - inadvertent, pilot in command (cause)
- In flight collision with object, descent - uncontrolled
  - object - tree(s)

## Analysis

THE PLT STATED THAT AFTER DESCENDING BELOW A LAYER OF CLOUDS NEAR THE REFUELING DESTINATION, THE TURBULENCE WAS EXTREME.  HE LOST CONTROL OF THE ACFT WHICH COLLIDED WITH TREES. HE FURTHER STATED THAT BEFORE DEPARTURE HE CHECKED THE WX VIA THE TELEVISION BUT DID NOT OBTAIN A WX BRIEFING GIVEN BY THE FAA FSS.
