BLUF: Do not use the engine as a step stool. Only use approved step zones on your helicopter.

Mechanics,
If you’re confused about why we keep mentioning how Black Hawk and Apache engines are no step zones, it’s because your feet are still breaking delicate engine connectors and parts.
Every time you use an engine as a stepstool or shortcut across a helicopter, stuff gets broken. That defeats the purpose of preventive maintenance.
Some of you step on the engine’s accessory gearbox, hydromechanical unit and IPS blower while gently traversing the engine nacelle—not realizing you’re damaging seals, splines and connectors at the same time.
Example of no-step areas
Consider the entire engine as a
no-step zone, though. Stepping on the engine results in broken parts, and all you’ll get for your effort is mission aborts, unscheduled maintenance and aircraft downtime.
Engine reliability depends on keeping your feet away. And it’s a good idea to spread the word to others.
