2000-12-13: Cessna 210C (N969RJ) — Boulder, CO

Boulder, CO, US

On December 13, 2000, a Cessna 210C (registration N969RJ) was involved in an aviation accident near Boulder, CO. Investigators recorded the probable cause as: Total loss of engine power due to fuel contamination (water), and failure of the pilot to have the airplane completely refueled. A factor was unsuitable terrain on which to make a forced landing. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

An airplane that had been dormant for nearly eight years experienced a complete loss of engine power shortly after takeoff. Water was found in the fuel system during preflight but was not fully removed. Post-accident examination revealed ice in the fuel manifold.

Background

The airplane had been inactive for almost eight years. Extensive checks and servicing were performed to prepare it for a ferry flight to a nearby airport, where it was scheduled to undergo an annual inspection. The Federal Aviation Administration issued a ferry permit. The night before the flight, the airplane was placed in a heated hangar.

Preflight and Ground Operations

During the preflight inspection the next morning, the pilot found 'a little water' in the gascolator and 'a tiny amount' in the right wing sump. He chose not to have the fuel drained and the airplane serviced with fresh fuel. He later told a local newspaper that he had drained the fuel system and thought he had removed all the water, 'but apparently it was not enough.'

The pilot was initially unsuccessful in starting the engine. After it was preheated, the engine started, and he performed 'an extended time warm up and extended pretakeoff run-up.'

Engine Failure and Forced Landing

Shortly after taking off, the engine lost 'complete power.' The pilot enriched the mixture and turned the auxiliary fuel pump first to LOW, then to HIGH. Power returned momentarily, but then the engine lost power again. The pilot did not have a chance to switch fuel tanks and instead concentrated on the forced landing. The airplane 'skimmed the tops of hills, went through a fence, nosed over, and tumbled 2 or 3 times.'

Post-Accident Examination

Later examination of the engine disclosed that the plunger in the fuel manifold was frozen in position, and there was ice in the chamber under the screen.
