Compass Swing

Can anybody supply the EASA reference regarding the continuing airworthiness of a magnetic compass? Aircraft is on an EASA C of A and maintained for flight training purposes.

Maintenance Requirements

The requirements should be contained in the approved Maintenance Programme, which in turn will be based on Maintenance data from the Design Approval Holder, such as a Maintenance Planning Document see Continuing Airworthiness M.A.302(i).

I only have experience of large aircraft, so apologies if I am barking up the wrong tree.

From the CAA info, it appears that this will be the case after Dec 2019 for any aircraft operated commercially, i.e.. Flt Training.

On the other hand, if we have left EASA by then who knows.

3 years......... though a check swing should be carried out if you have an engine change or avionics fit, anything that may effect it.

It was covered under LAMPS, see item 119

The full info is in leaflet 34/ 20 see

FWIW, for UK-registered aircraft CAP 562 (CAAIP Leaflet 34-20, page 1032) deals with this subject, but I'm not sure how applicable this document is to the various classes of aircraft in an EASA environment, or how its validity will be affected by a no-deal Brexit, so it may not be much help.
