Blind squirrel.
Please can you point me to the regulation that states that you need a Biennial flight check, in the USA, even with a CAA/EASA piggy back licence?
I have been through all the regulations regarding this & haven't seen any evidence of your statement.
On the back of my FAA piggy back licence it states that all privileges stated on the CAA/EASA licences apply to the FAA licence while in date & not revoked.
Also how do you record the biennial? The FAA don't give you any paperwork to log it on as proof.
My CAA Biennial is in date as I have recently completed it & sent the relevant paperwork off to the CAA with my instructors signature recorded on my CAA/EASA licence. As is my Medical.
My EASA licences are the proof that I hold the relevant privileges.
Cheers trev
