As an operator/owner, if a change in a product affects compliance with an airworthiness directive, what must you do?

When a change in a product affects compliance with an airworthiness directive, it is essential to request GACA approval for an alternative compliance method. This step is critical because airworthiness directives are issued to address safety concerns and ensure that aircraft continue to meet regulatory and safety standards.

By seeking approval for an alternative compliance method, the operator/owner demonstrates a commitment to maintaining airworthiness while also addressing the specifics of the change made to the product. This approach ensures that any modifications do not compromise safety or compliance with established regulations.

Continuing to operate without changes would violate safety regulations and potentially put both the aircraft and its occupants at risk. Notifying passengers of a change, while transparent, does not address the regulatory requirements. Submitting a proposal for redesign may be a part of ensuring compliance in some scenarios, but the primary step in response to an affected airworthiness directive is to formalize an alternative method with GACA.
