Dear C212,
I think it is clear enough tbh.
1) Yes he is considered inexperienced. IF, it is a new type to an AOC/Introduction of a new type, then your NAA has the right under EASA to present a safety case as experienced, to provide crew training/operations. For example, I was a LTC on the Falcon 2000 series, and was nominated as an experienced LTC from completion of type rating to complete all the flight crew training.
2) No, he would not be considered as inexperienced, provided he had completed enough hours to meet the experienced requirement, prior to his renewal. This is best managed through your OM-D in terms of his previous experience and also your requirements for Line Training to get said crew member back up to speed.
Feel free to get in touch with any other Q's.
