What must be done before beginning any structural modifications on an aircraft?

Before beginning any structural modifications on an aircraft, it is essential to review and follow the approved engineering documentation. This documentation provides crucial guidelines, specifications, and processes that ensure the modifications are carried out safely and in compliance with regulatory standards. Adhering to this documentation helps maintain the integrity of the aircraft’s design and safety features, as it includes instructions that have been specifically evaluated and authorized by engineering professionals.

Following approved engineering documentation protects the aircraft from potential issues that could arise from unauthorized changes. It ensures that modifications are made within the parameters established by the aircraft manufacturer or regulatory bodies, thereby minimizing the risk of compromising safety or performance. Additionally, this practice supports accountability and traceability in maintenance operations, which is vital in aviation environments.

While other options might be relevant actions in the overall process of modifying an aircraft, consulting engineering documentation is a foundational step that must occur before any physical work or communication with other personnel takes place. This prioritization helps establish a clear and informed approach to any structural modifications.
