bose,
Under EASA there is no 'three month window' for SEP Revalidation by Experience. Once the required second year experience is gained get the Rating signed up asap.
Unfortunately, on National Licences, an SEP Rating can still only be Revalidated during the 3 months prior to expiry.
A bit of a 'nuisance' for those who have both a Part-FCL and a National Licence !

Not quite right. I had to renew my Part-FCL just recently and there still is the 90 days rule for renewal - you only keep your renewal date, if the bi-annual training flight is within 90 days before SEP expires. You can go earlier, indeed, on a checkride with a FE, if experience requirements are met, but this will extend your SEP two years from the checkride date, not the SEP expiration date. Under EU regulations time between checkrides never exceed 2 years.
