ou might think, crewmen, that spitting oil and blowing smoke from a re-
installed engine means pulling it again to have AVIM replace a bad seal. But,
the problem may be that you tilted the engine when you removed it for AVIM
repair or when you re-installed it after repair.
When you remove and install an engine or maneuver it around on a mainte-
nance stand, sometimes the engine gets tilted.
When that happens, oil seeps from the A-sump through internal seals and
puddles in the bottom of the swirl frame. Some of that oil gets blown through
the inlet particle separator, or leaks through the stage 4 bleed tubes of the com-
pressor stator split line.
You won’t be aware of those leaks until the engine is back on the aircraft spit-
ting oil and blowing smoke.
So it’s steady as you go when
removing and installing an engine or
maneuvering one on a maintenance
stand. Just like with pinball games,
tilting means you lose. Tilt an engine
and you’ll have an oily mess to clean
up.
If you see smoke in the exhaust,
clean the engine and continue to
operate it to burn off the oil like it
says in Troubleshooting Procedure

our Apache’s radio console takes a
beating when you take out the heavy
crew seats. It also gets dinged during
other maintenance inside the cockpit.
Once you bend or break knobs,
switches and dials, you’ve ended
your communicating.
So protect the console. Get your
sheet metal shop to make a cover
from .040-in aluminum sheet.
Use these dimensions:
Make sure all edges are smooth
before you use the cover. And paint it
red so you won’t forget to remove it
when your work is done.
Make sure the cover does not rest
on any knobs, dials or switches when
you install it. Keep your feet off the
cover too—it’s not a foot rest.
Drill a small hole in one corner of
the cover and attach a “Remove
Before Flight” streamer.
