Sealing of Integral Fuel Tanks
- Aerospace Standard
How well the basic design lends itself to good sealing (key design factors to consider include accessibility and minimal movement, among others)
The choice of sealant; where it is applied; how it is applied
How well the substrate surface is prepared
Whether sealant fillet dimensions are optimum for air vehicle configuration and flight dynamics
The degree of resistance of the sealant to the fluid and thermal environment
The degree of engineering insurance -- i.e., application of adhesion promoters to sealant bond surfaces, application of organic topcoats over sealants, proper drainage of the fuel tank, etc. -- employed for technical risk reduction.

Scope AMS Committee G9, Aerospace Sealing, shall be primarily concerned with the sealing of aerospace vehicles for fluid containment and environmental protection by the use of sealants which are applied and cured to solid materials or are permanently mastic. This includes the preparation of sealant material specifications, aerospace recommended practices for sealing processes and related activities. Examples of applications are the sealing of integral fuel tanks, fuel cell cavities, crew compartments and passenger areas, access doors, fasteners, avionics compartments, windshields, firewalls, etc. The committee shall also be involved with elastomeric fuel cells. The committee shall address the effort on the environment of cured and uncured sealant materials and their containers and recommend approved practices for their proper disposal. The committee shall also be involved with elastomeric fuel cells. The committee shall participate in discussions on various sealing materials and processes and provide comments and views on relevant research and development efforts.
