Plain English Summary

2/10 complexity

This directive requires owners and operators of Piper PA-31T3 aeroplanes to inspect the main landing gear forward side braces for cracks and to retire certain brace part numbers after a set service life, with inspections triggered early if the gear has been used above allowed speeds. Installing redesigned replacement braces (P/N 85165-02 or -03) ends the inspection requirement. It matters because brace cracking has been found and failure could cause landing gear collapse.
