What should I do if I buy a new aircraft?

"Please send an email to [email protected], providing your account number, aircraft registration number and the fuel required. On reception, the customer service department will issue you with a new card. 
For a TICPE-exempt JET A-1 card, you must attach the TICPE exemption or an AOC/CTA that specifies the new aircraft's registration number.  "

Is this useful ?
