Plain English Summary

3/10 complexity

This AD requires operators of Cessna 182 and Wren 460 series aircraft fitted with main undercarriage U‑bolts P/N 0541153 to inspect those bolts for cracks/damage and confirm nut torque: visual inspections in situ every ≤100 hours and magnetic‑particle NDT after removal every ≤500 hours (torque per the Cessna Service Manual).

It affects aircraft owners/operators by imposing recurring inspections, possible bolt removal, NDT equipment or contractor use, and associated labor, downtime and compliance costs to detect load‑bearing failures earlier.
