Brackett BA-104 Complete Air Filter Assembly
The Brackett BA-104 Complete Air Filter Assembly is an FAA-approved aircraft engine induction air filter system designed for installation on a broad range of certified general aviation aircraft.
Unlike a replacement element alone, the BA-104 is the complete filter assembly and is designed to use the readily replaceable Brackett BA-3 filter element for routine servicing.
The BA-104 is approved under STC SA693CE and is applicable to numerous Piper, Beech, Britten-Norman, Brantly and Aero Commander aircraft installations.
Its replaceable-element design provides a practical long-term filtration solution: once the BA-104 assembly is installed, routine filter servicing is performed by replacing the BA-3 element as required rather than replacing the complete assembly.
Always verify aircraft model, serial-number applicability and current approved installation data before installation.
