I have had a bit of a look at the requirements for ETOPS approval. Although there are a number of regulatory hoops to be passed through I am unable to find anything that refers to, or requires any tech crew experience other than the ability to hold an ATPL appropriate to the aircraft.
It refers to engine/airframe combinations - Airbus input
Systems reliability
Systems redundancy
Maintenance procedures
Airport Availability
Weather Criteria
etc
I cannot find a single reference to minimum aircrew experience for ETOPS.
Am I missing something? Or is this all just a big windup by AIPA?
