- Date: July 22, 2003
- Aircraft: Cessna 525 CitationJet CJ1
- Location: Coupeville, Washington, United States
- Fatalities: 0
- Phase of flight: En route
- Cause: A failed K6 relay on the pitch trim printed circuit board caused a single-point trim runaway. A latent design flaw in the autopilot/trim disconnect logic prevented disengaging the trim motor, and the pilot did not recognize the runaway in time.
A Cessna CitationJet CJ1 corporate jet suffered a runaway electric pitch trim, which left the nose pushed down and very high control forces. The pilot did not recognize the trim runaway in time to pull the trim circuit breaker and ditched the aircraft in a marine cove. All occupants were uninjured.
