MH/CH-47 Weight Reduction Project
Fulcrum Concepts developed a package of components that improve the performance, safety, and reliability of the MH/CH-47F&G Block II while reducing component weight by 38% below OEM (101 lbs).
This series of components feature identical form-fit-function to OEM, while also incorporating design features that resolve known issues affecting aircraft durability, safety, and time-dependent weight gain.
The MH/CH-47 weight reduction kit demonstrates Fulcrum’s expertise in producing upgrades that enhance aircraft performance and safety while minimizing the need to retrain aircraft crew and maintainers.
