Abstract:

This project was initiated to verify andor extend the 10-year shelf and service life, and to determine environmental and functionability aspects of the Fire Extinguisher Valve cartridge when installed in aircraft. Thirty cartridges of the latest manufacture available 1957 and 36 cartridges of various ages 1952 to 1957 were used as a control lot to obtain empirical data. Two hundred and ninety-six cartridges manufactured in 1950 and 1951 were environmental conditioned and tested for shelf life. Fifty cartridges which had previously been installed in aircraft were further conditioned and tested for serviceability. As a result of the test it is recommended that the shelf life remain at 10 years. Cartridges installed in aircraft should be inspected at each 100-hour inspection and replaced after 500 aircraft flying hours. Author
