My last 330 PPC was 18 months ago conducted by an EK TRE. I paid to get the 330 put on part 1 of my UK/JAA licence in April 06.My licence ran out in September. When I was on the phone to the Belgrano, they pulled up my records on their computer and indicated it was no problem to renew my licence using my 330 rating.
When enquiring about the 380 rating the inference was that I only needed 500 hours P1 time to include it. I'm not sure that's entirely correct and think I would need a UK TRE to conduct a skills test on the 380 as I did for the 330. That could prove to be more of a challenge!!
As things stand I will go to LGW in the next couple of months and try and renew with the 330 rating.
Will report back!
