T
he new F model Chinooks are showing up at units. With them, mechanics, there’ll be
new maintenance tasks required to take care of this bird with its new avionics and more.
When
you
±rst
enter
the new bird, check out
the digital cockpit and all
the multi-functional display
(MFD) screens .
There are dos and don’ts
for MFD screens.
Don’t,
at
any time, use unauthorized
glass
cleaners
on
them.
That’s because commercial
cleaners
contain
abrasive
chemical
substances
that
will scratch the screen and
impact NVG viewing.
Do,
at all times, use the authorized glass cleaner, NSN 7930-01-442-5969, and the
wipes that come with it. Make a note until the cleaner is added in the next IETM change.
This will include procedures for cleaning the MFDs.
There’s no doubt high-pressure water will clean your bird, but the consequences
will be costly repairs. High-pressure water damages wire bundles, seals, the fnish,
connectors, electrical components, and washes grease out oF lubricated parts.
Use low-pressure water and a little elbow grease while cleaning your bird. Never try
to blast away the grime.
AFter every washing, check For standing water in your bird and remove the water to
prevent corrosion.
Stay up on aircraFt washing and corrosion control by Following the good words in
TM 1-1500-344-23,
Cleaning and Corrosion Control,
and TM 1-1500-204-23,
General
Aircraft Maintenance.
Wash your bird as oFten as local operating conditions require. And remember to
Follow your engine manual TM when cleaning your engine. See the washing instructions
described in the IETM For the Longbow, D-model and TM 1-1520-238-23-1.
