Registration Number Reserved

Yes!
I got the N - number I wanted. Six Tango Tango. The letter arrived in the mail very quickly, a lot quicker than I thought it would take, so hats off to you folks at the FAA! The letter came from:

U.S. Department of Transportation
Federal Aviation Administration
Civil Aviation Registry
Aircraft Registration Branch (AFS-750)
P.O. Box 25504
Oklahoma City, OK 73125-0504

Now for clarification, this is just the reservation for an N-number. The airplane has not been assigned that N-number. So the next step is to submit in writing the aircraft manufacturer, model, serial number, and current registration number. Oh yes, and send in the fee!

Thanks FAA, look forward to doing business with you in the future!
