Crashed CV-580 Had Reversed Elevator Trim Cables
Last September 1, a Convair CV-580 (N587X) operated by Air Tahoma crashed while attempting to return to Rickenbacker International Airport (LCK) in Columbus, Ohio. The captain, first officer and a company pilot sitting in the jumpseat were killed. It was the first flight after Phase 1 and Phase 2 maintenance that included flight-control cable rigging. In a preliminary report, the NTSB says, “On-site inspection of the accident airplane revealed that the elevator trim cables were reversed.” The cockpit voice recorder showed that the captain repeated the word “pull” 27 times while the pilots apparently battled in vain to trim the aircraft. The NTSB also states that an inspector had not signed off cards for numerous checks during the aircraft’s last phase inspection last August. Among the items included in these checks was the crucial connection of elevator servo trim-tab cables. The FAA revoked Air Tahoma’s operating certificate following a post-accident review of the carrier.
