    If I send the Altimeter in and get it back with certification reinstall it and do the static check myself as a A&P as long as the transponder is current cert. does this meet the IFR requirement.

    Are you a mechanic or a repair station?

    An owner-pilot can neither reinstall the altimeter nor perform the required static check on their own. Reinstalling a removed altimeter is going to require a static check under 91.411.

    under 91.411 you can do the static check required if you have the required and calibrated equipment to do the checks required by far43 appendix e. the tests required by far43 appendix f must be done by a repair station with proper certification.

    Yes, provided it is not an encoding altimeter and you follow Part 43 App E. If encoding type then you would need to recheck the transponder system. Don't forget to make a new 24 month Altimeter system sign off to reset the clock. However, having the altimeter and xspndr on two separate 24 month schedules could set you up to over-fly one or the other inspection.

    Working on an altimeter is not the same as working on the transponder system.
    you can remove and replace the altimeter, leak check it and not bother with the recerts of the transponder

    I was wondering where the correction to my first post went, it seems somehow to have ended up in a thread on antibiotics:

    Missed the "A&P" part. Not seeing it as needing a repair station like the
    alitmeter or encoder, but you need to both visually inspect the static system and have the equipment to pump down the static system (1" mercury or 1000' indication on the altimeter) and hold it there, for a minute. The specs for this are in part 25 (yes, these apply even for non-transport aircraft).

    Yep, where do you think the AC text came from? Verbatim from the reg.

    How do you get the calibration done on that test equipment?

    Don't forget the piece of tape to close off the other static port (if there is one). Don't forget to remove the latter.

    No calibration check needed if altimeter was checked on the bench as mentioned by OP. Only need to comply with the system proof check to the limits mentioned above, which this method works fine.

    The AC simply provides a more complete answer for those who may want to learn a little more

    And a piece of thin-walled plastic tubing and vise-grips to complete an Acme pitot-static test kit.

    What calibration? You suck the altimeter up a thousand feet and see if the bleed down exceeds that specified in the regs quoted above.
