FAA AC 25.173 Stability & Control Certification Testing
In aerospace and aviation, stability and control are critical factors that ensure aircraft safety during flight. The Federal Aviation Administration (FAA) mandates compliance with Advisory Circular (AC) 25.173 to establish standards for the structural integrity and dynamic characteristics of an aircraft's stability and control systems. This service focuses on providing comprehensive testing solutions tailored to meet these stringent requirements.
The FAA AC 25.173 certification process involves multiple stages, including design analysis, manufacturing inspection, assembly verification, and final flight tests. Each stage is crucial in ensuring that the aircraft can withstand various environmental conditions without compromising safety or performance. Our laboratory specializes in simulating these conditions to validate the stability and control characteristics of aircraft components.
Our testing services encompass a wide range of methodologies designed to evaluate different aspects of an aircraft's stability and control systems. These include wind tunnel tests, computational fluid dynamics (CFD) simulations, ground vibration tests, and flight test evaluations. By leveraging advanced instrumentation and sophisticated software tools, we ensure accurate and reliable results that meet or exceed FAA standards.
To begin with, our experts conduct comprehensive design reviews to assess the initial stability and control characteristics of newly developed aircraft designs. This step helps identify potential issues early in the development process, allowing for necessary modifications before proceeding to more extensive testing phases.
Once the design is finalized, we proceed with manufacturing inspections and assembly verifications. These activities ensure that all components are manufactured according to specified tolerances and assembled correctly. During this phase, our team performs detailed inspections using non-destructive testing techniques such as magnetic particle inspection (MPI), ultrasonic testing (UT), radiographic examination (RT), and eddy current testing (ECT).
After successful completion of manufacturing checks, the next step is to conduct ground vibration tests. These tests simulate the forces experienced by an aircraft during takeoff, landing, and taxiing operations. By subjecting the aircraft structure to controlled vibrations within our specialized facilities, we can measure its response under realistic conditions.
The final phase of the FAA AC 25.173 certification process involves flight tests conducted at various altitudes and speeds. These flights provide valuable data on how the aircraft behaves in different atmospheric environments. Our experienced pilots and engineers gather extensive information about stability, control, handling qualities, and other key performance indicators.
