## Probable cause

THE PILOT'S ENTRY INTO AN EXCESSIVE MANEUVER AFTER TAKEOFF WITH INSUFFICIENT ALTITUDE AND AIRSPEED TO COMPLETE THE MANEUVER, WHICH RESULTED IN A STALL/MUSH INTO TREES.  FACTORS RELATED TO THE ACCIDENT WERE:  HIGH DENSITY ALTITUDE AND TREES.

## Sequence of events

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

- In flight collision with object, maneuvering - turn to reverse direction
  - weather condition - high density altitude (contributing factor)
  - maneuver - excessive, pilot in command (cause)
  - altitude - inadequate, pilot in command (cause)
  - airspeed - inadequate, pilot in command (cause)
  - stall/mush - inadvertent, pilot in command (cause)
  - object - tree(s) (contributing factor)
- In flight collision with terrain/water, maneuvering - turn to reverse direction
  - terrain condition - mountainous/hilly

## Analysis

A WITNESS STATED THE ACFT ENTERED A STEEP CLIMB AFTER TAKEOFF FROM A STRIP NEAR A RIVER IN MOUNTAINOUS TERRAIN. HE SAID THAT WHILE STILL CLIMBING, THE ACFT BEGAN A 180 DEG 'U-TURN' (WING-OVER) & HEADED FOR THE GROUND. SUBSEQUENTLY, IT HIT TREES, CRASHED ON UNEVEN TERRAIN & BURNED. IMPACT OCCURRED ON A HDG THAT WAS NRLY PERPENDICULAR TO THE RWY DRCTN. ELEV OF THE CRASH SITE WAS ABOUT 4730 FT; THE ARPT ELEV WAS 4701 FT. NO PREIMPACT PART FAILURE OR MALFUNCTION OF THE ACFT WAS FOUND, THOUGH THE ELEVATOR TRIM CABLE WAS FOUND STRETCHED IN A NOSE-UP (TAB DOWN) DRCTN. THE COMPANY HAD SUSPENDED ONE OF THE PLTS FOR PERFORMING A SIMILAR MANEUVER ON 3/5/90, AFTER INADVERTENTLY ENTERING A BOX CANYON AT LOW ALTITUDE.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Accident 19900615020519A](https://openairdocs.org/incident/19900615020519A), Jun 15, 1990: Cessna TU206G, Indian Creek, ID, Destroyed, 2 fatal. Observed to take off in an extreme nose high attitude, climb several hundred feet, then steep right dive to ground.

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.
