Verification ensures that all components, from wing spars and fuselage structure to engine mounts and control systems, meet the specified design and construction standards. For example, the witness verifies the proper installation of control cables, confirming their correct routing, tension, and security. This meticulous inspection process minimizes the risk of component failure during flight.
-
Material Integrity
The verification process includes inspecting the materials used in construction. The witness verifies that materials meet the required specifications and are free from defects. For instance, the witness might examine welds for proper penetration and integrity, ensuring the structural strength of the aircraft. This scrutiny is essential for preventing material-related failures.
-
Assembly Accuracy
The witness verifies the accuracy of the assembly process. This includes confirming the proper alignment of parts, correct torque values for fasteners, and adherence to approved construction techniques. For example, the witness might inspect the alignment of wing ribs to ensure the correct aerodynamic profile. Precise assembly is critical for maintaining stability and control in flight.
-
Documentation Thoroughness
Verification extends to the documentation of the build process. The witness meticulously documents each inspection, providing a detailed record of the construction progress. This documentation serves as evidence of compliance with EAA standards and provides a valuable resource for future maintenance and inspections. Complete and accurate records are crucial for establishing the aircraft’s history and airworthiness.
These facets of verification, executed through the EAA witness program, contribute significantly to the safety and reliability of amateur-built aircraft.
