Plain English Summary

5/10 complexity

This airworthiness directive requires operators of Cessna T303 aeroplanes fitted with Slick model 6220 or 6224 pressurized magnetos to install a clear cockpit placard instructing pilots to do a magneto check before each flight and to carry out a 100‑hour inspection (and repeat every 100 hours or whenever the AFM check fails). The measures respond to a reported moisture‑contamination risk that can cause engine stoppage and impose a recurring maintenance and pre‑flight check obligation on affected operators.
