C-130 Engine Change Cart

In 2018 JE worked directly with U.S. Air Force maintainers at Patrick Air Force Base to develop a purpose-built tooling cart for one of the most complex maintenance tasks in the C-130 fleet.

01 The challenge

Tools in Four Places Instead of One

C-130 engine change procedures require specialized tools — including propeller removal equipment — often stored across multiple locations, creating lost time, disorganized workflows, and inconsistent setup across crews and shifts.

Tooling stored away from the job JE cart — everything at the point of use
Every tool gets a defined location, so a crew can see what is missing before the job starts — and after it ends.

02 The solution

Designed From Maintainer Interviews

Through direct engagement and end-user interviews at Patrick Air Force Base, JE identified the specific inefficiencies in tooling storage and staging, then engineered a dedicated cart to support the full engine-change workflow from staging through execution.

03 Operational impact

In Continuous Field Use Since 2018

Crews now arrive with tools organized and ready at the point of use, with defined storage locations ensuring accountability before and after each job — improvements reflected in continued active use years after deployment.

Let's Turn Your Requirements Into a Solution

Have a maintenance task your crews work around rather than through? Start with what the maintainers say, not the tool list.
