When is an Immediate Action TD assigned?

An Immediate Action Technical Directive (TD) is assigned when unsafe conditions exist that could potentially lead to serious injuries or loss of aircraft. This designation emphasizes the urgency of addressing critical safety-related issues that could pose a risk to personnel or equipment. The aim is to rectify dangerous conditions as quickly as possible, ensuring the safety of both the crew and the aircraft. Immediate Action TDs require prompt compliance to mitigate risks effectively.

Other options involve scenarios that do not meet the criteria for Immediate Action. Minor maintenance issues would typically not require an immediate directive, as they are not urgent and can often be scheduled for resolution. Scheduled maintenance updates are part of routine procedures and do not reflect imminent threats that necessitate swift action. Similarly, equipment that is operational does not indicate a need for immediate intervention unless there are identified hazards that must be addressed without delay.
