Abstract: A system and method for relieving pressure from a passenger cabin of an aircraft during a decompression event with a resettable decompression system. The system includes a resettable decompression retainer having a swing arm pivotably connected to a base. The swing arm has a bias relative to the base provided by a spring connected to both the swing arm and the base. The swing arm engages a slip fitting that is attached to a ceiling panel of the aircraft. The resettable decompression system allows the ceiling panel to move thus allowing air pressures between a passenger cabin and a crown space to equalize. After a decompression event, the resettable decompression retainer can be manually reset without the use of tools and without repairing or replacing the resettable decompression retainer.
