Every two years one must get the FAR 91.411 and 91.413 inspections, commonly called "VFR certs" and "IFR certs". These checks can be made in the airplane, but many shops much prefer to have the altimeter and encoder brought into the shop for checking out in the test chamber. Then all that has to be done at the airplane is the static system and transponder check after the altimeter and encoder are reinstalled. Removing and reinstalling the altimeter and encoder can be a real nuisance and costly if you have the shop do it. How easy is it going to be to remove and reinstall the EFIS yourself? OC PS: The last time I insisted that the shop technician do the job in the airplane (in very cold weather, but inside the hangar) he "couldn't get the encoder to calibrate at the low end". He then proceeded to remove both the altimeter and the encoder and took them into the nice warm toasty shop where the encoder checked out perfectly in the chamber with no adjustment what ever. I had to pay significant bucks because he did the extra work of removing and reinstalling the encoder and the altimeter. Next time I'll go back to removing and reinstalling those two items myself as I have done previously and save that extra cost.
