M130 Chaff Dispenser…
M
echanics, maintenance on the M130 chaff dispenser shouldn’t turn into a job for
the AVIM shop.
When doing any repair on the
payload module’s retaining plate or
installing the payload module,
don’t overtighten the stud nuts.
Snug is enough—too much torque
and damage occurs. Always use the
ball screwdriver, NSN 5120-01-
079-9644 and don’t use a T-handle.
Overtightening can break the
stud nuts or the screws on the
back end of the retaining plate.
That means your chaff dispenser
is NMC until AVIM can repair it.
Of course, always protect the
dispenser when it’s on an aircraft
on the ground with a nylon
cover, NSN 1730-01-456-2557.
