Narrative:
Air Iowa Flight 333, a Beech E18S, operating as a scheduled air taxi passenger flight, crashed into an open, plowed field, while approaching the Davenport-Municipal Airport, Iowa, for a landing. The accident occurred approximately 3 miles southwest of the Davenport Airport. The pilot and five passengers were fatally injured. There were no injuries to persons on the ground. The aircraft was destroyed by impact forces; there was no fire.


The National Transportation Safety Board determines that the probable cause of this accident was the in-flight failure of the right wing, which resulted from a preexisting fatigue crack in the lower spar cap of the wing at wing Station 81. Although the fatigue crack existed and was discernible during inspections conducted over the 6-year period prior to this accident, it was not detected.
