CH-47D/F: A Step Up for Maintenance

    Mechanics, are you tired of straining to reach the top of the aft rotor head on your Chinook?

    Now there is some relief. You can get a step up with the aft rotor pylon step (ARPS).

    The ARPS is especially helpful when you have to remove, service or install the aft rotor head. Without the ARPS, you’ll have to guide the crane and remove all the components before the rotor head can be removed. Problem is, you’ll be doing all this work reaching overhead in a position that is uncomfortable for even the tallest mechanic. 

    The aft rotor pylon step will give you a step up so you can perform your task from a better position.

    When using the step, keep these points in mind for your safety.

   An ARPS should be attached to the aircraft with each hook firmly seated on the cap structure of the WL 119 deck with its base resting firmly on the work platform for more support.

  The ARPS can be used on both sides of the aircraft at the same time.

   Because of limited space and for safety purposes, only one mechanic should be standing on each ARPS.

   The capacity of the stand is one mechanic, tools and equipment not to exceed 400 lbs.

    For a copy of the step plans see drawing below. (Click to enlarge for the entire plan.)
