## Probable cause

THE IMPROPER FUEL PUMP HIGH END DISCHARGE ADJUSTMENT.  A RELATED FACTOR IS IMPROPER MAINTENANCE/ANNUAL INSPECTION.

## 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
  - fuel system,pump - pressure excessive (cause)
  - maintenance,annual inspection - improper, other maintenance personnel (contributing factor)
  - fuel system,pump - pressure excessive
  - emergency procedure - performed, pilot in command
- Forced landing, descent - emergency
- In flight collision with object, descent - emergency
  - object - tree(s)
- In flight collision with terrain/water, landing - roll

## Analysis

THE PILOT STATED THAT AS THE AIRPLANE BEGAN TO CLIMB OUT THERE WAS A LOSS OF ENGINE RPM AND THE ENGINE STARTED TO RUN ROUGH.  A POST-ACCIDENT ENGINE RUN-UP WAS CONDUCTED.  THE ENGINE STARTED EASILY AND OPERATED NORMALLY AT LOW POWER SETTINGS. AFTER A WARM UP PERIOD THE THROTTLE WAS ADVANCED TO 2500 RPM, AND 'THE ENGINE THEN STARTED TO RUN ROUGH, WITH BLACK SMOKE AND FLAMES COMING OUT THE EXHAUST... .'  A FUEL PUMP BENCH TEST REVEALED THE HIGH END DISCHARGE ADJUSTMENT WAS SET HIGHER THAN RECOMMENDED.  THE TEST STAND DISCHARGE GAGE PEGGED ON THE HIGH SIDE WHEN THE RPM WAS ADVANCED TO 2600 RPM PER TEST PARAMETERS.  THE AIRCRAFT HAD FLOWN 1.1 HOURS SINCE THE ANNUAL INSPECTION WAS COMPLETED 8 MONTHS BEFORE THE ACCIDENT.  LOGBOOKS INDICATED THE ENTIRE FUEL SYSTEM WAS REMOVED, OVERHAULED, REINSTALLED AND ADJUSTED IN DECEMBER, 1990, APPROXIMATELY 4 FLIGHT HOURS BEFORE THE ACCIDENT.

## 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 19920614021629A](https://openairdocs.org/incident/19920614021629A), Jun 14, 1992: Cessna 210B, Belleville, IL, Substantial damage. Rough engine on climbout tried return but tail struck trees then impacted in field. Fuel pump set too rich.

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.
