Plain English Summary

4/10 complexity

This Airworthiness Directive requires operators of Cessna 182 and Reims‑Cessna F182 aeroplanes fitted with SMA SR305‑230 piston engines to carry out the actions in paragraph 3 of SMA Service Bulletin SB‑C182‑71‑002 (or a later DGAC‑approved revision) before next flight. It was issued because cold‑weather testing showed a risk of engine flameout at low power, so the directive imposes operating limitations intended to prevent engine stall and forced landing.
