Hutchinson™ Aerospace designs and manufactures engine vibration isolation systems to meet the exacting standards of the aircraft industry. 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 each engine overhaul. The PMA'd 7350721-7 has a spacer located between the molded assemblies providing proper installation positioning and pre-compression when isolator is installed. * 7350721-7 supersedes 7350721-1 thru 7350721-6 for use on the PT6A-20 and PT6A-27 engines on the specified de Havilland aircraft. |
