Unfortunately the IC-A210 was approved for installation (by an appropriately approved person) for VFR operation below 10,000ft under CAR 35.
CASA has advised that as CAR35 has lapsed, an approval appropriate to CASR 21 is now required. This has proven uneconomic and impractical in the short term. In the longer term, a fully TSO'ed version (which will be acceptable to CASA) is planned.
RAAus requires that fixed mount radios have a CASA approval. To quote from the RAAus tutorial:
"If it is a fixed installation only Civil Aviation Safety Authority [CASA] approved apparatus may be used; refer to AIP GEN 1.5 para 1.1. "
As the IC-A210 approval is no longer valid, Icom can't import it, as it would then fall under ACMA rules, and it is not ACMA approved either. However, as we understand it, as usual, under grandfathering provisions, planes with the A210 installed while the radio was approved can continue to use them.
