While doing maintenance, the cover is removed for MOC. But when it’s time
to reinstall the cover, don’t shove it back in place too hard and push on the screen.
That’s because the blades are behind the generator cover.
When you push the screen too far in it gets in the way of the generator fan blades.
When you run up your bird, the spinning fan blades will rub against the screen
scraping off Fne metal particles that can get ingested into the generator and cause it
to fail. Then your bird will be NMC until the generator is replaced.
On your next inspection, check to make sure the screen is out of harm’s way of the
blades. If the screen is pushed in too far, use a pair of needle-nose pliers to pull the
screen back in place away from the blades.

echanics, the once hard-to-get Fre extinguisher squibs for your Chinook are now
available in the supply system.
Just order the extinguisher squibs with NSN 1377-01-185-2622 and NSN 1377-
00-172-0428.
And there’s more good news.
When the shelf life or service life
of the squibs expire, don’t discard
them after removal. The Rock Island
head shed wants squibs returned so
they can determine whether they can
extend their shelf or service life for
reuse.
To get the shipping information for
expired squibs, contact the quality
assurance manager, Cecil Cook, DSN
793-7584, (309) 782-7584 or email:
