Is the PBS-4100 used only when engines need balancing?
No. The PBS-4100 is a tool that can be used to solve many vibration related problems: Because all engines vibrate – the PBS-4100 can tell you exactly how much, and what is causing the vibrations. For example the PBS-4100 will discriminate between vibrations coming from the fan and the turbine. It can also tell you if a fuel pump is causing a significant amount of the vibration. This information in invaluable, and can help you avoid unnecessary engine removals and test cell visits. When used on-wing, the PBS-4100 quickly indicates if trim balancing the engine(s) will resolve the problem and enable you to keep the aircraft in service. The quicker you know what needs to be done with the aircraft, the sooner the schedulers can make their final plans! When operating the PBS-4100 on-wing, users can perform all the vibration tests that can be perform in a test cell. Trim Balancing can take less than 1 hour on-wing thereby permitting fast turn-around of the aircraft and almost immediate return
