It's not new news, alas. In terms of back-filling NI contributions, you cannot fill a gap-year for which you were contracted out (in other words, those years that you were contracted out of the basic state pension (bps), and consequently, into AFPS). There has been a drip feeding of bad news about pension stuff, generally.
Just a quick reminder, contracting out of AFPS ends next month. [Archive] - PPRuNe Forums
Everyone has a 'starting/foundation amount' for their bsp. There are two types of starting amounts' one is linked to the old basic pension plus state earnings-related pension (SERPS), and there is the new bsp based on 35 years of contributions minus a deduction for past contracting out in a public sector pension, such as AFPS. It is this latter one which is causing so much grief for those so close to bsp retirement. For most others still serving, it's not so much as issue. By the time you get to bsp age (97 at the last count, I think), you'll have accrued thirty five years. It won't apply to everyone, but if in doubt, contact TPAS:

As an aside, we have seen the government being holed left, right and centre by the WASPI campaign. Part of that campaign is based on the premise the ladies weren't contacted. I believe I'm right in saying this, but everyone who may have been able to make good any shortfall, should (could?) have been contacted.
Call TPAS - a superb pension service. Run by Michelle Cracknell, a great chief exec, ex scaley brat and a fondness for the RAF - her dad was aircrew on the V Force.
