McFarlane Beechcraft flight control cables and chains are coated with a corrosion inhibiting compound that meets Military Specification MIL-PRF-16173. This is the same compound used on all factory original Beechcraft flight control cables.

McFarlane Aviation flight control cables offer quality that is second to none in the aircraft industry. Our quality assurance procedures and personnel are relentless, ensuring that our aircraft flight control cables meet the highest standards possible. These standards exceed the military specifications that govern aircraft flight control cables. Each McFarlane cable assembly is made from the highest quality U.S. manufactured materials from suppliers that have been listed by the U.S. government as being tested and qualified for government use (QPL listed). Samples selected from each lot of cable and terminals are inspected for dimensional conformance to applicable specifications and subjected to a test load equal to 100% of their rated minimum breaking strength. Every cable terminal swaged on a cable assembly is inspected for proper dimension. All cable assemblies produced are pre-stretched to eliminate rigging and growth changes after installation. In addition, each and every McFarlane cable assembly must endure a sustained proof load equal to 60% of the cables minimum rated breaking strength assuring the safest and highest quality aircraft flight control cables available.
