echanics, one sure way to put the engine on your Black Hawk or AH-64 on the
NMC list is putting your feet where they don’t belong!
Your aircraft have work platforms for standing and step areas for your feet, so
keep your feet where they belong.
Engines have many items attached that if stepped on, will snap, crack or pop.
If you don’t want to suffer the agony of defeat then keep your feet off of the engine
temperature bulb, the engine alternator connector, the engine starter speed sensor
wiring, the engine bleed air tube and the hydromechanical unit (HMU). Stepping on
the HMU causes internal damage to the spline.
Sometimes the damage is not obvious. For example, stepping on the starter speed
sensor can damage the internal connections. Then the starter will not sense the engine
speed and won’t shut off after the engine reaches optimum speed. So, the pilot has to
shut off the starter manually.
UH-60/AH-64…
The Feet Cause Defeat
can you
hear that
sound?
it’s the AVIM shop mechanic
giving you a piece of his/her mind
for breaking connectors, wires,
and busting lines with your feet.
use your bird’s step zones
to keep it off the nmc list.
The work platform is for your feet.
The engine is not a step zone
