New 406 ELT - Installation requirements
I am considering replacing my ACK E-01 (121.5) ELT with the soon to be available (!) E-04 with seems to be the most economical 406 mHz ELT on the market. Advantages - COST and also plug and play replacement for the E-01 (installation time quoted as less than 30mins - plug in new unit which has same footprint as E-01 and replace the antenna).
However, it has been suggested that even a simple swap in/out may require an engineering order (EO) - is that the case?
How does buying the unit from the US go, especially with regards to registering it with AMSA?
Thanks in advance.
