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?
