Re filling 02 systems
Posting on behalf of a mate who recently purchased a TB20 from USA with a factory fitted O2 system. The cylinder/s are fixed into the airframe and cannot be removed, except by a LAME. Most suppliers in Australia seem to work on cylinder exchange rather than refill and they don't have this specific type of cylinder anyway.
Does anyone know of airports around Oz that have the equipment to refill these systems as my mate can only top up when he is back at his home airport from a cylinder he gets from BOC gas.
