Nose Gear Door Registrations

Sat Apr 24, 2004 2:58 am

I have a simple question.

I've noticed that most aircraft carry the last letters of their registrations on the nose gear door. Anybody know why? Is it to help identification on the ground? And is there any particular reason for not writing the complete registration?

Thanx in advance  Smile/happy/getting dizzy

Usually, those numbers are used by the company to identify the aircraft. For instance, aircraft N57101 will be identified as Aircraft 101.

" Is it to help identification on the ground?"

Yes.

"And is there any particular reason for not writing the complete registration?"

Yes again. With the size restrictions imposed by the area available, you would have to be rather close to read the number had it been painted there in full.

Cheers,
Fred

There is also the case when the fleet number doesn't match the actual registration at all. For instance many DL aircraft (777s?).

AA uses three character alpha-numeric fleet numbering system which hasn't matched acft registration numbers for a long time now.

Delta ship 333 is N334DL.

on NW aircraft they match the first 3 numbers of the registration
on CO aircraft they match the last 3 numbers of the registration
here are some examples

062=N76062
5528=N528US
008=N78008
1235=N235US

these are just some examples.

Does anyone know what the significance of the 007 is? Its not in the reg #.

BTW, long time lurker, first time poster. I've learned alot from this forum, hopefully I can contribute something sometime.

kerberos... the thread already established that not all airlines use any form of the a/c reg on the gear door. some use company a/c numbers which are probably in a rough order of delivery...

the aircraft below has a nose gear door number "005" and the a/c reg is
C-GLWS

NOTE that the a/c also has the same identifier painted in the very top of the tail.

98% of AirTran's 717s registrations are N9__AT, but the nose numbers start with 7__

At Air NZ the last 1 or 2 letters of the registration are painted on the door. This is a CAA requirement to allow easy identification on the ground.

Wilco - Thanks, I realized that after I posted  Smile - not sure yet how to go back and edit.

Kerberos, welcome to the forums! You can only edit within a certain number of extra posts and/or time. At least that's what empirical evidence tells me.

I always thought that the reg was there so that A.nutters could know what they were flying  Big grin

LH usually has the last two letters of the registration on the nose gear doors (and the tip of the V-Stab), the first three being "D-AI" for Airbus and "D-AB" for Boeing, The Canadairs have "D-AC" afaik, and the Avro's "D-AV"

An NW DC-9 Captain explained to me once that there is a logic to the "tail numbers" of most of their DC-9s:

DC-9-10s will have 91XX
DC-9-30s will have 99XX
DC-9-40s will have 97XX
DC-9-50s will have 98XX

On top of that, I think that their DC-10s all are 1XXX, like COAB767 said about N235US (1235) & N234US (which I was on in 2000....1234  Big grin)

Kerberos, to answer your question, Westjet displays the Fleet Identification Numner on both the nose gear door and top of the vertical stabilzer.

An interesting note about Westjet is that you will never see a FIN# ending in the number 4. This is apparently a result of a few superstitious management that used to work for other airlines that had bad experiences (crash/incidents) with aircraft with 4's in their FIN#'s.

BTW, that James Bond logo has since been removed.

Andy - Thank you for the information, that's interesting about the number 4. I'm sure there are alot of superstitions in the airline industry when it comes to Reg #'s, flt #, etc - but thats a topic for another thread.

To bad they removed the JB logo, I guess I can stop looking for it now!

I had noticed that Westjet skips the digit 4 in their fleet #'s, but I did not know why. Thanks for the info, Dripstick. Many Chinese carriers skip 4 as well, because the Chinese word for "4" sounds like the word for "death."

Fin numbers are assigned by the airline for their own purposes. Air Canada uses 200 series numbers for its A320's and A319's, 100 series for the CRJ's, and so on. When AC picked up Cdn Airlines' 737's (which were 700 series), they changed all the numbers to 500 series to avoid confusion with DC-9's, which were also 700 series. Of course, all the DC-9's are retired now. The 737's will be gone by the end of the year.
