Just got a "service Letter in the mail from Parker. *Dated Feb 15,
2008 It states that "All Parker/Airborne engine driven air pumps are
beyond their mandatory replacement time and must be removed from
services"

Part 91 pilots can continue to run the pumps just fine. Many pilots
have complained that the letter is written as if its an AD with the
force of the FAA behind it. It is not.
