Explained in plain English

What is an airworthiness directive?

An Airworthiness Directive (AD) is a mandatory instruction from aviation authorities to correct unsafe conditions in aircraft. If a specific window type, like the one on Ljubisa Karovic's Ryanair flight, was found to have a defect, an AD would be issued, requiring airlines to inspect or repair all affected planes to ensure safety.
