## Probable cause

POWER LOSS DUE TO LOW FUEL PUMP PRESSURE AND A CHAFED UPPER DECK REFERENCE LINE.  A FACTOR WAS:  THE PILOT'S INABILITY TO MAINTAIN DIRECTIONAL CONTROL DUE TO A PARTIALLY EXTENDED MAIN LANDING GEAR.

## Sequence of events

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

- Loss of engine power(total) - mech failure/malf, takeoff - initial climb
  - fuel system,pump - pressure too low (contributing factor)
  - fuel system,line - chafed (contributing factor)
  - gear retraction - premature, pilot in command (cause)
- Forced landing, descent - emergency
  - gear extension - attempted, pilot in command
- Loss of control - on ground/water, landing - roll
  - directional control - not possible, pilot in command

## Analysis

THE PILOT SAID HE TOOK OFF, RETRACTED THE LANDING GEAR, AND CLIMBED TO AN ALTITUDE OF ABOUT 100 FEET WHEN THE ENGINE SUDDENLY LOST POWER.  THE PILOT EXTENDED THE LANDING GEAR FOR AN ON AIRPORT FORCED LANDING.  WHEN THE AIRPLANE TOUCHED DOWN, THE NOSE GEAR HAD EXTENDED AND LOCKED BUT THE MAIN GEARS WERE ONLY PARTIALLY EXTENDED.  THE PILOT WAS UNABLE TO MAINTAIN DIRECTIONAL CONTROL AND THE AIRPLANE SKIDDED OFF THE RUNWAY.  POST ACCIDENT EXAMINATION DISCLOSED THE ENGINE DRIVEN FUEL PUMP COULD NOT PRODUCE RATED PRESSURE AT HIGH POWER SETTINGS.  IN ADDITION, THERE WAS A HOLE IN THE UPPER DECK REFERENCE LINE DUE TO CHAFING AGAINST THE GENERATOR MOUNTING BRACKET.

## 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 19920526020589A](https://openairdocs.org/incident/19920526020589A), May 26, 1992: Cessna T210H, Boulder, CO, Substantial damage. Engine lost power on climbout. Put gear down but hit runway gear intransit. Fuel pump defect and hole in fuel line.

## Other investigations on N57AB (1)

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.

- [NTSB LAX06CA135](https://openairdocs.org/ntsb/LAX06CA135), Apr 2, 2006: Cessna T210H (N57AB), Wells, NV, substantial damage. Probable cause: the pilot's inadequate compensation for the gusty crosswind conditions and failure to maintain directional control.
