I have been thinking about registration numbers recently, probably because Benny told me that he has reserved the original registration number for his aircraft and intends to re-register it after he finishes the recovering job. Registration numbers are interesting because of the history they tell.

Most of the N3Ns mustered out during/immediately after the war received registration numbers of 44xxx and 45xxx. In the years following the war, aircraft were registered as 50000 and 60000. Most of these aircraft are no longer registered with these numbers but there are quite a few old ag photos of these “mid” date aircraft.
A few birds were mustered out from time-to-time over the years., continuing on into the 80000 series. I understand that after the war the depot started with about 100 aircraft that were rotated in-and-out of Annapolis, gradually reducing in number. The final birds out of Annapolis (1957-1961) received registration numbers with four digits and an alpha character on the end (i.e. N9999Z).
There have been lots of additional registrations issued. Some have been issued randomly by the FAA for restorations, expirations or transfers. Then there are the custom registrations. These tend to come in (3) flavors – those with “N3N” in their sequence, those that use the Navy Bureau number and personalized numbers with special meaning to their owners.
I especially like the bureau number registrations. Many of these came out of the Hendrickson stable. These make great call signs – “Navy Four Four Zero Nine turning base runway three-two” – that’s a lot like their original military call signs (although most N’s did not have radios in their active-duty days).
So of the current registrations (a hundred eighty-some, depending on the day you run the report), how do these break out?
Early muster: 44000 – 45999: 114 aircraft
Mid muster: 50000 – 80000: 60848, 61072, 61829, 87697
Late muster: 4742C, 5078Q, 5820J, 6358T, 6395T, 6396T, 7752C, 7753C, 7863C, 8528Z, 9181R, 9309Z, 9312Z, 9316Z, 9317Z, 9834Z
Bureau Numbers: 2616, 2860, 2896, 4409, 4417, 4487 (the FAA maintains registrations for NASM / NMNA aircraft 2693, 3022, 3046)
“N3N” type: N3NN, N3NP, N3NY, N3NZ, N33NR
Others: that leaves about 40 personalized and/or transfer registrations. Some are pretty easy like personal initials “582WH” (Hi Bill!). Some I can’t figure out – like “71N”. My favorite is “66CV” (I sleuthed it out, can you? Google is your friend…).
Comments are open (click on “Reply” above, just under the title). I would love to hear any history of your aircraft’s N-Number, especially if it is one of those 40 or so unique registrations.
