On May 3, 1992, 38-year-old Brian Thomas Barber was a passenger on a twin‑engine Cessna 340, tail number N69469, that departed Yakutat, Alaska, bound for Anchorage. Pilot Jeffrey Roth, Timothy Thornton, Kent Roth and Scott Roth were also aboard. The flight was on instruments at its assigned altitude of 12,000 feet when routine radio contact was lost; FAA controllers recorded that last transmission and the aircraft disappeared thereafter.

The pilot’s wife later reported hearing what she believed to be her husband on air‑traffic tapes mentioning 6,000 and icing conditions several minutes after the recorded last transmission. The FBI Laboratory performed an enhancement of the tapes but could not confirm an additional transmission. Weather along the route was described as instrument meteorological conditions. No wreckage or bodies were ever found and the NTSB concluded the probable cause as a missing aircraft due to undetermined causes.

Anyone who has information about the flight, the passengers or sightings along the Yakutat–Anchorage route that day is asked to come forward.
