The short answer
Airworthiness Directives (ADs) are mandatory orders from the FAA to correct an unsafe condition on a specific aircraft, engine, or component. Compliance is required to keep the aircraft airworthy, and an aircraft's AD-compliance status is an important factor in its value, insurability, and financing — check it carefully in the pre-buy.
What ADs Are
When the FAA identifies an unsafe condition likely to exist on other aircraft of the same design, it issues an Airworthiness Directive requiring specific action — an inspection, a modification, a repair, or an operating limitation — sometimes one-time, sometimes recurring. Compliance is mandatory to keep the aircraft legally airworthy. Some ADs are minor; others, like the Cessna 210 wing-spar AD, are significant and costly.
Why AD Status Matters When Buying
An aircraft's AD-compliance record is part of its value and financeability. An airplane with all applicable ADs complied with (and recurring ones current) is worth more and finances more easily than one with outstanding ADs or findings. Confirm AD status carefully in the pre-buy inspection — an unaddressed or expensive AD can change the deal, affect insurance, and require negotiation before closing.

Related Questions
Is AD compliance mandatory?
Yes — ADs are mandatory to keep the aircraft airworthy. Non-compliance grounds the aircraft legally and creates liability.
Can ADs be expensive?
They range from minor to costly. Some, like the Cessna 210 wing-spar AD, are significant. Check AD status carefully before buying.
How do I check an aircraft's AD status?
Through the logbooks and a pre-buy inspection that reviews applicable ADs and confirms compliance, including any recurring inspection intervals.
