In late 2016, it was brought to the attention of the SafeTech Quality and Development team that one of our customers had several evacuation slides in for service with cylinders that had reached, or were about to reach, their life limit of 24 years.
SafeTech contacted the OEM for a cylinder replacement quote but, due to the age of the equipment, the OEM was unable to supply any replacements, making the slide non-repairable and with almost no replacement or surplus slides available, potentially grounding their fleet of aircraft.
After exhausting all options for alternate cylinders as listed in the CMM, the SafeTech team contacted the OEM to request engineering drawings. Consulting with the OEM, a new source for the cylinder was identified and engaged in the development of a replacement cylinder.
SafeTech invested in the development, tooling and production of the cylinder, which were accepted by the OEM. The SafeTech cylinder was then inserted into the latest revision of the CMM as the OEM replacement.
The cylinders were successfully fitted to the evacuation slides, the overhauls completed and the slides are on board the customers aircraft today.
