## Sequence of events

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

- Loss of engine power(partial) - nonmechanical, takeoff - initial climb
  - fuel system,carburetor - undetermined (cause)
- In flight collision with object, takeoff - initial climb
  - proper climb rate - not possible
  - object - tree(s) (contributing factor)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

AFTER LIFT-OFF ON INITIAL TEST FLIGHT OF THIS HOMEBUILT ACFT, THE ENGINE CEASED TO DEVELOP FULL RPM. THE PLT WAS UNABLE TO ESTABLISH A RATE OF CLIMB TO CLEAR TERRAIN OBSTACLES IN THE FLIGHT PATH, COLLIDING FIRST WITH TREE TOPS AND THEN THE GROUND. PLT SUSPECTS CARB MAY HAVE BEEN SET TOO RICH FOR EXISTING CONDITIONS. MIXTURE NOT ADJUSTABLE IN FLT.

## 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 19840811039789A](https://openairdocs.org/incident/19840811039789A), Aug 11, 1984: Amtr MONI, El Dorado, AR, Destroyed. Unable to climb after liftoff due to insufficient power. Struck trees. Carburetor caused an over rich fuel mixture.

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.
