AA Reusing Nose Numbers

Thu Aug 10, 2017 9:19 pm

I recall reading several years ago that one of the reasons why AA uses unique alphanumeric nose numbers for some aircraft types (3AA, 5DJ, 7LW, etc.) was because their system couldn't handle reusing nose numbers or four-character identifiers. How much of that is still true, if it ever was?

I noticed that with the delivery of N908AA last week, AA is reusing ship number 908, which was formerly N908AW, an LUS 757.



(also, the 900 series has to be the most confusing range at AA, consisting of LAA and LUS A321s, LUS 757s, and LUS E190s in non-contiguous blocks)

Tail numbers are the actual registration numbers, the nose number is the internal ID, typically painted on the nose and/or landing gear doors.

At least in the case of FOS, as long as the previous aircraft data is wiped, you can re-use a nose number. Likewise, the same tail number can have multiple nose numbers without any issue (happened with some of the Skywest CR2s around the merger) other than that the cycles in FOS don't match up with reality. As far as I know, the Mainline limitation was with a Maintenance piece of software but I don't know any of the details beyond that.
