## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for all airplanes equipped with Aero Advantage ADV200 series (part numbers ADVPL211CC and ADVPL212CW) vacuum pumps installed under supplemental type certificate number SA10126SC, through field approval, or other methods. This proposed AD would require you to remove any affected vacuum pump and related monitor system, remove the applicable airplane flight manual supplement (AFMS) and placard, and install an FAA-approved vacuum pump other than the affected part numbers. This proposed AD results from several reports of pump chamber failure. We are issuing this proposed AD to correct problems with the vacuum pump before failure or malfunction during instrument flight rules (IFR) flight that can lead to loss of flight instruments critical for flight. The loss of flight instruments could cause pilot disorientation and loss of control of the aircraft.
