Aircraft Accident/Incident Report

Longmont, Colorado 80501
Friday, October 18, 1996 12:30 MDT

NTSB Narrative Summary Released at Completion of Accident

Shortly after lift-off, the right engine lost power, and the pilot made a wheels-up landing in an alfalfa field. Examination of the right engine's top spark plugs showed evidence of operating at a rich mixture. Both auxiliary fuel pumps were on during the takeoff roll. Cessna Service Bulletin MB88-3, requiring the removal of the fuel pressure sensing system and auxiliary fuel pump switches, had not been accomplished. Functional testing later proved the auxiliary fuel pump was operating but an excessively rich fuel mixture was being delivered to the right engine by the fuel servo.

NTSB Probable Cause Narrative

The partial failure of the fuel control servo, causing an excessive flow/output of fuel to, and flooding of, the right engine.
