If you have that, then you are in free circulation, have proof and are golden. If you don't have it stamped then I think you have a problem.
Even at your home base, it can be an immense problem to resolve a VAT issue and HMRC can detain the aircraft at your cost 'forever'. Moreover, there is no real legal basis to get detained goods released (other than HMRC deciding to release them, political leverage or a judicial review)
