ost of the time, mechanics, when you read PS, it’s always some component or
item that needs a little T-L-C, extra maintenance or attention to detail.
Well, this time it’s changing or cleaning the APU intake barrier air filters, NSN
2945-01-328-9679. You’ll need to inspect it more often than the 10 hour/14 day
inspection requirements when in a desert environment to solve the problem of a
clogged APU.

does its job of collecting dust and sand
in the desert so well the filter eventual-

APU.

after every flight make sure you clean
them or change them if they’re clogged.
