He has a 1979 M20K
From the TCDS:
Required equipmentSerial No. 25-0001 thru 25-0999.
But I should have read Note 24:
NOTE 24: Aircraft models that originally were certified with vacuum powered attitude systems that have those systems
replaced with a non-vacuum powered attitude system: If the Primary Attitude system has been replaced with an
FAA Approved STC’d installation that meets the requirements of 14 CFR 23.1303(f)(i)(ii)(iii)(iv)(v)(vi),
23.1311(a)(1)(2)(5)(6)(b)(c), 23.1321(a)((c)(d)(1), 23.1331(a)(b)(1)(2)(c), thereby leaving no operational systems
dependent on a Primary or Standby (if equipped) Vacuum system, then the Primary and Standby (if equipped)
Vacuum pumps and associated lines, manifolds, etc may be removed from the aircraft. Refer to engine
manufacturer’s instructions of removal and capping off of engine driven vacuum pumps.
As always the devil is in the details.
