- Date: December 4, 2004
- Aircraft: Convair CV-580
- Location: McAllen, Texas, United States
- Fatalities: 0
- Phase of flight: Approach and landing
- Cause: Failure to activate the hydraulic pump, which left the pilot unable to maintain directional control after landing.
During a maintenance test flight at McAllen, the left engine was shut down after a propeller malfunction and the crew flew a single-engine ILS approach. With the hydraulic pressure gauge at zero and the alternator light on, they landed, but the DC hydraulic pump was switched on too late to restore nose-wheel steering and brakes. The aircraft left the runway, hit the perimeter fence and entered a drainage ditch.
