AIRCRAFT ACCIDENT REPORT. AIR IOWA, INCORPORATED, BEECH E18S, N310WA, DAVENPORT, IOWA, APRIL 19, 1973

Air Iowa, Inc., Flight 333, a Beech Aircraft Model E18S, N310WA, scheduled as an air taxi passenger flight, crashed into an open field about 1704 c.s.t., on April 19, 1973, while approaching the Municipal Airport, Davenport, Iowa, for a landing. The pilot and five passengers were fatally injured. There were no injuries to persons on the ground. The aircraft was destroyed by impact. 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 on 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.
