Summary

The Federal Aviation Administration proposes to revise an earlier airworthiness directive for Cessna 310, T310, 320, 401, 402, 411, and 421 series airplanes, which would replace fuel and oil flexible hose assemblies with improved designs on certain models and allow for the use of equivalent assemblies on other models.
