Even examiners make mistakes
My JAA PPL was up for renewal 27/05/2002 but as I had plenty of hours and an hour with a JAA instructor I revalidated through the experience route on 17/12/2001.
The FE signed my certificate of re-validation but put the expiry date now 17/12/2003, and also failed to send in the SPA LPC to the CAA.
As I was re-validating in the last 12 months of 2 years then the new expiry date should have been 24 months from the ORIGINAL date of expiry, ie. 26/05/2004.....
Ah well, you live and learn...
Cheers
