If you paid your type rating cost of Euro 33k to CAE directly and not the lower (Vat free) sum of approx Euro 27k, the following from my Irish acountants probably also applies to you if you did your type rating in 2009:
[The Vat refund] is based on final invoice date and then it can only be filed quarterly.
Its 6-12 months from date of filing, as advised by the Dutch Tax authority.
...we file all Vat returns required and we follow up on all returns filed by us
I am still waiting...
