As a Piper Archer owner on the UK register I administer my own AMP and have always had a requirement to calibrate the ASI/ALT and Transponder every two years to enable flight under IFR in controlled airspace. The regulations for doing so have been listed as being in CAP 562 for the instruments and in accordance with EASA_SIB_2011-15R2_1 for the transponder. I'm aware of the FAA requirements on the subject.
In the process of updating the AMP I've run into some confusion regarding the rules surrounding the ASI/ALT. I can't find anything in CAP 562 that covers the subject so can only think that something's been deleted since my AMP was drawn up. As this was about ten years back it's quite likely.
Having scoured the CAA and EASA websites I can't find any reference to the requirement to calibrate the instruments on a biennial basis and would like to ask if anyone knows where the ruling is (if it still exists).
Thanks in advance.
