These systems are designed to reduce the magnitude of vibration transmitted from the propeller/powerplant to the airframe. Isolation provides: reduced pilot fatigue, passenger comfort, and maximum protection of the aircraft structure and systems from the damaging effects of vibration. To maintain maximum performance and protection from the isolation system, replacement is recommended at every engine overhaul. Hutchinson Aerospace has been granted Parts Manufacturers Approval (PMA) for vibration isolation assembly type number 94011-20 installed on the aircraft listed below. For complete product definition, some systems require two 94011-20 and two 94011-02 or two 94011-20 and two J-9613-72HA. Hutchinson Aerospace holds PMA for these isolation systems as well. Each isolator consists of: two molded assemblies, a spacer, and a washer. The spacer located between the two molded assemblies provides proper installation positioning and pre-compression.
