P/N SS32092-4

This bar type adaptor provides a connecting seal for the two main static ports and is applied to the aircraft fuselage, using the two studs to attach the unit to the fuselage on the left side of the aircraft. After use, the storage position in the case serves as a pre-test assembly to verify the integrity of the adaptor, hoses and the air data tester.
