## Sequence of events

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

- Loss of engine power(partial) - mech failure/malf, takeoff - initial climb
  - ignition system,spark plug - contamination (cause)
- In flight collision with terrain/water, takeoff - initial climb
  - aircraft weight and balance - improper, pilot in command (cause)
  - load jettison - delayed, pilot in command (cause)
- Nose over, takeoff - initial climb

## Analysis

THE ACFT COLLIDED WITH THE GROUND AFTER TAKEOFF. THE PILOT SAID THE ACFT LOST POWER AND FELT SLOPPY AT ABOUT 350 FT AGL.HE ADDED POWER BUT MAXIMUM OBTAINABLE WAS 2000 RPM AS OPPOSED TO 2300. THE PILOT SAID HE TRIED TO DROP THE LOAD BUT THE LOAD REMAINED WITH THE ACFT. THE HOPPER DUMP VALVES WERE OPERATIONAL. THE ACFT WAS ABOUT 1000 LBS OVER MAX GROSS WEIGHT. THE FRONT ROW OF SPARK PLUGS EXHIBITED CARBON DEPOSITS AND THE MAIN OIL SCREEN HAD TRAPPED HEAVY CARBON DEPOSITS WITH A SMALL AMOUNT OF FERROUS METAL. THE ACFT NOSED OVER DURING THE LANDING.

## 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 19830613025209A](https://openairdocs.org/incident/19830613025209A), Jun 13, 1983: Scwzer G164A, Crookston, MN, Destroyed. Tail heavy after takeoff and unable to maintain altitude. Failed to dump over gross load. Crashed in a bean field.

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.
