Michigan Aviation performs the 24-calendar-month pitot-static, altimeter and transponder tests required by FAR 91.411 and 91.413 at its FAA Part 145 repair station (certificate KL2R956K) at Oakland County International Airport. Checks can be scheduled alongside other avionics or maintenance work during the same visit.
FAR 91.411
To fly IFR in controlled airspace, each static pressure system, each altimeter and each automatic pressure altitude reporting system must have been tested and inspected within the preceding 24 calendar months under Part 43 Appendices E and F. The static system must also be retested after it is opened and closed (other than using system drains and alternate static valves), and the integrated system must be retested after installation or maintenance on the altitude reporting system where a data correspondence error could be introduced.
You may not fly IFR in controlled airspace above the maximum altitude to which all altimeters and the altitude reporting system were tested. Read FAR 91.411.
FAR 91.413
A transponder required under FAR 91.215(a) may not be used unless it has been tested and inspected within the preceding 24 calendar months under Part 43 Appendix F. This applies to VFR flying too, wherever a transponder is required.
After installation or maintenance where a data correspondence error could be introduced, the integrated system must be retested under Appendix E. Read FAR 91.413.
Authority
The aircraft manufacturer, a properly equipped repair station holding an appropriate instrument, limited or airframe rating, or a certificated mechanic with an airframe rating for static pressure system tests only.
A properly equipped repair station holding a Radio Class III or appropriate limited rating, a Part 121/135 continuous airworthiness maintenance program holder, or the aircraft manufacturer if it installed the transponder.
So an A&P can perform the static system portion, but not the altimeter, altitude reporting or transponder tests.
Scope
The results are recorded in the aircraft maintenance records.

FAQ
Every 24 calendar months, plus after certain maintenance described above.
The 91.411 altimeter and static checks apply to IFR flight in controlled airspace. The 91.413 transponder check applies whenever a transponder is required, VFR or IFR.
An A&P with an airframe rating can do the static system test only. The altimeter, altitude reporting and transponder tests need a properly rated repair station or the manufacturer.
Yes. Avionics and maintenance are on the same field at KPTK, so the work can be scheduled for the same visit.
You cannot fly IFR in controlled airspace until the 91.411 tests are current, and you cannot use a required transponder until the 91.413 test is current.
No. The VOR check under FAR 91.171 is a separate IFR requirement and is not part of the 91.411/91.413 tests.
Send your tail number and the date of your last check, and we will confirm scheduling at KPTK.
