## Sequence of events

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

- Abrupt maneuver, takeoff - initial climb
  - airspeed - not maintained, pilot in command (contributing factor)
  - proper climb rate - not maintained, pilot in command (contributing factor)
  - distance - misjudged, pilot in command (cause)
  - pull-up - excessive, pilot in command (cause)
  - stall/mush - intentional, pilot in command (cause)
- In flight collision with object, maneuvering
  - object - tree(s) (contributing factor)

## Analysis

SHORTLY AFTER TAKEOFF PILOT WAS ADVISED OF MODEL AIRCRAFT IN FLIGHT PATH, EVASIVE ACTION TAKEN, HOWEVER, PRESENCE OF MODEL NOT CONFIRMED. PILOT REDUCED PWR BELOW RECOMMEDED RPM CAUSING AIRCRAFT TO SETTLE. PILOT THEN APPLIED PWR TO AVOID COLLISION WITH TREES. WHEN IT APPEARED THAT THE AIRCRAFT WAS GOING TO CRASH THE PILOT REDUCED PWR AND STALLED THE AIRCRAFT COLLIDING WITH TREES. A CHECK WITH MODEL AIRPORT REVEALED THAT NO MODEL AIRCRAFT WERE BEING FLOWN AT THE TIME OF THE REPORTED INCIDENT. A PASSENGER ON BOARD THE AIRCRAFT DID NOT SEE THE REPORTED MODEL AIRCRAFT. THERE WAS A HIGH RIDGE AT THE FAR END OF THE RUNWAY USED FOR TAKEOFF ONLY 300 FT ABOVE RUNWAY LEVEL. PILOT REDUCED POWER ON TAKEOFF AFTERRAISING LANDING GEAR TO A POWER SETTING BELOW THAT INCORPORATED IN THE FLIGHT OPERATING SPECIFICATIONS.

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

- [Accident 19840817043839A](https://openairdocs.org/incident/19840817043839A), Aug 17, 1984: Tmpson NAVION*, Bordheadsville, PA, Destroyed. Reduced power on climbout due report model aircraft. Got below power curve unable clear trees. Stalled into same.

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.
