Says Operators Don't Need To Be Grounded For Long
On the heels of a February 15, 2008 Service Letter 72 to all
operators of Parker/Airborne dry vacuum pumps on piston engines,
mandating immediate removal of these units, Airwolf Filter Corp
advises its wet-vacuum pumps are available immediately for
operation of gyros (Series 200) and de-icing boots (Series
400).
