This CID describes a portable helium leak detector, which will be used to determine the location of leaks in fuel tanks as well as other aircraft systems. By filling a fuel tank or container with helium (the helium acts as a tracer), the helium leak detector will enable aircraft maintainers to locate the origination point(s) of the leak(s) as the helium escapes into the atmosphere.Intended Use: The purpose of the helium leak detector is to locate small leaks that are often found within tanks or containers. This will allow the aircraft maintainers to take corrective action and patch or fill the leaking areas.
