Plain English Summary

1/10 complexity

What this does: This is an aviation safety order (called an Airworthiness Directive) that applies to specific light aircraft—American Champion, Aeronca, and Bellanca models.

Who it affects: Owners and operators of these aircraft that still have aluminium fuel lines running through the engine compartment.

What you must do: Replace any aluminium fuel lines in the engine compartment with fire-resistant hoses or fireproof metal lines and fittings. This reduces the risk of fuel leaking onto hot engine parts and causing a fire.

Important exception: You do not need to replace vent lines or drain lines, because if those fail, they don't create or worsen a fire hazard.
