Summary

De Havilland, Inc. has revised its proposed airworthiness directive for the DHC-8-100 and -300 series airplanes, replacing a previously proposed rule that would have required repetitive inspections and installation of a modification to terminate those inspections, with a new rule that proposes a different terminating modification due to concerns about the effectiveness of the previous modification.
