At AirSupport Group, we understand that compliance with airworthiness directives is crucial to ensuring safety and efficiency in commercial flight operations. Aircraft must be maintained in optimal operating condition, and these directives are an essential component of this process.
“Complying with airworthiness directives is not just a technical obligation, it is an ethical commitment to the lives and trust of those who fly. At AirSupport Group, we understand that each standard represents a lesson learned in the history of aviation, and our duty is to turn that knowledge into preventive action, operational discipline, and sustained excellence in every commercial flight we serve”, explains Iván Navarro, CEO of AirSupport Group.
Thanks to our 35 years of experience, we have in-depth knowledge of what these orders entail, and that is why we want to tell you what they are about and how AirSupport Group can help you ensure compliance with these regulations.
What are airworthiness directives and why are they important?
Airworthiness directives (ADs) are orders issued by civil aviation authorities, such as the Civil Aviation Authority of El Salvador (AAC), that require aircraft operators to take certain actions to correct identified safety conditions. These directives are mandatory and aim to preserve airworthiness safety.
“In El Salvador, we promote a culture of compliance that goes beyond regulations: we promote a comprehensive safety mindset that strengthens the country’s competitiveness. Each directive we implement reinforces the confidence of airlines, protects passengers, and positions our nation as a regional benchmark in responsible aircraft maintenance and operation,” said Navarro.
There are several types of ADs that vary in terms of the urgency of the action required:
- Emergency airworthiness directives: These are urgent orders that must be complied with immediately or within a short period of time due to a critical safety condition that could put the aircraft or passengers at risk.
- Non-emergency airworthiness directives: These ADs allow for a longer compliance period but are still mandatory to ensure that aircraft remain operational and safe.
Compliance with these directives is not only necessary to comply with the law, but also essential to protect passengers and crew during flight operations.
Types of actions required by airworthiness directives
Airworthiness directives may require different types of actions, depending on the problem identified. The most common actions include:
- Detailed inspections: These directives may order specific inspections of certain aircraft components to detect possible faults or damage.
- Replacement of parts or components: In some cases, ADs require the replacement of parts that are defective or do not meet safety standards.
- Design modifications: Some orders may require modifications to the aircraft to correct design flaws or improve safety.
- System maintenance: ADs may include requirements to perform maintenance work on certain aircraft systems to ensure their proper functioning.
It is essential that aircraft operators keep detailed records of all actions taken to comply with each AD, ensuring that the aircraft continues to comply with safety regulations.

How to comply with airworthiness directives on commercial flights?
Complying with airworthiness directives is a process that requires detailed planning, precise execution, and continuous monitoring. Here are the key steps to comply with these directives:
1. Keep an up-to-date record of airworthiness directives
Each aircraft must have an up-to-date airworthiness directive record, which includes information on the ADs issued for that aircraft. This record must detail:
- The dates of issue of the ADs.
- The actions required by the AD.
- The compliance dates and actions taken.
Proper record-keeping allows for easy tracking and ensures that directives that must be complied with are not overlooked.
2. Take the necessary corrective actions
Once the AD requiring action has been identified, the next step is to perform the necessary inspections, repairs, or modifications. This may involve tasks such as reviewing systems, repairing components, or updating software on the aircraft.
3. Prepare a compliance report
After performing the required actions, the entire process must be documented. This includes a detailed compliance report that must be reviewed and approved by the competent aviation authority. The report must include a description of the actions taken, the parts replaced, and any tests performed.
4. Perform periodic follow-ups
Airworthiness directives may be revised or updated at any time. Therefore, it is important to perform periodic follow-ups to ensure that aircraft continue to comply with new regulations and AD updates.
5. Coordination with aviation authorities
It is essential to maintain constant communication with aviation authorities, such as the AAC, to ensure that all regulations are being followed. The authorities can also provide advice and clarification on the ADs that must be complied with.
