Soar High
with
Shadow PM
Preflight Inspections
Always perform every PMCS inspection and check
outlined in your TM before Fight. Even when PMCS
becomes old hat, never trust your memory. Always
depend on the TM so you don’t miss anything.
Do all of your pre-Fight inspections and before
engine start checks like it says in TM 1-1550-689-CL,
Operator’s Manual and Crewmember’s Checklist.
Solar Shields
In searing heat, never leave the Shadow’s wings uncovered. The sun’s heat can
warp the carbon ±ber wings. Protecting the wings with solar shields also minimizes
fuel loss through the fuel tip relief valve.
²uel loss is caused by fuel expansion as it gets hot. The lost
fuel is supposed to get caught in the overFow container on the
wing tip relief valve. But if the valve fails, the fuel pouches
rupture inside the wings. The fuel system is dependent on
ZERO air ingestion at the engine, and a vacuum leak will
cause air ingestion 99.99 percent of the time.
Shadow Unmanned
Aircraft System…
The Shadow tactical
unmanned aircraft
system (TUAS)
can’t
soar high on its
mission unless PM
soars high with it!
Never
let me
sit in direct
sunlight without
soLar Shields!
Use TM for maintenance, not your memory!
Hey, thanks
for the PM!
Now I’ll
soar
through this
mission.
I love it
when PM comes
together!
That’s
what
I’m talkin’
about!
