As a result of the fire, the three squadrons training to fly the V-22
at Marine Corps Air Station New River, in North Carolina, are now
flying the aircraft with air cleaning devices - called engine air
particulate separators, or EAPS - switched off.

The devices filter dirt and debris in the air that can cause premature
wear and tear when sucked into the giant turbine engines that turn the
V-22 rotors.

Darcy said the air cleaning device did not cause the fire, but that
switching the system off would prevent a recurrence of this particular
incident.

So how exactly are they going to fly into Iraqi duststorms this year
without working EAPS?

That's not what the article says, though. The EAPS work, they're just
not using them at the current time, and it doesn't say that they won't
be using them in Iraq.
