Sometimes an aircraft, or component has an airworthiness concern that requires urgent attention. To achieve that, the Director issues an Emergency Airworthiness Directive (AD) notified directly to the registered operators of affected aircraft. Emergency ADs can be issued at any time, and are issued where compliance is required before further flight, or is less than 50 hours TIS, or 28 calendar days.
