Lockheed Martin Tactical Aircraft Systems - Ft. Worth, Texas
Technical Orders (T.O.s) are maintenance and repair instruction books for military weapon systems. They reference the use of products containing hazardous chemicals, many of which are ozone-depleting compounds (ODCs). Due to the 1996 phaseout of Class I ODCs, it became necessary to identify replacement products for those T.O. materials containing Class I ODCs. The study involved a review of each T.O. to identify all chemicals or chemical products, analysis of each product to find the ones containing Class I ODCs, testing of candidates replacements, and incorporation of the verified replacements in the appropriate T.O.s.
Over two thousand Lockheed Martin-managed F-16 T.O.s were reviewed, leading to approximately 900 referenced chemicals. Of these products, 66 were found to contain one or more Class I ODCs. This encompassed a wide range of products, including release agents, adhesion promoters, antiseize compounds, circuit refrigerants, retaining compound primers, greases, corrosion preventive compounds, coatings, and cleaning solvents. Replacement candidates were identified on an application-by-application basis. In some cases, lab testing was performed. Other required only shop trials for verification, or were simply incorporated after thorough engineering study of issues such as functionality, material compatibility, economics, and health/safety.
The replacements were incorporated into the T.O.s during 1996, and procurement data was provided to the inventory managers at applicable field units. The program was considered extremely successful, providing ODC-free maintenance and repair instructions for the 3,600-plus F-16s currently active in domestic bases as well as bases around the world.
