Spinnygirl,
I do know of somebody who did get a 6 month extension, (which also happens to expire in a couple of weeks time!).
The good reason in this case was the original Modular Training Provider went out of business!
As Broomstick Pilot says there is no harm in asking. The CAA aren't all bad, but telling them you just haven't had time probably won't help. So make it good!
