part numbering in component maintenance manuals according to ATA

part numbering in component maintenance manuals according to ATA

part numbering in component maintenance manuals according to ATA

(OP)

The Air Transport Association rule says the following:

"Blank spaces and special characters, with the exception of the dash (-), are not permitted in part-number structures. The dash (-) is permitted only between numeric characters (Ref.[ATA SPEC 200] or/or ATA SPEC 2000])."

For example, the part number for a MS24693-C51 screw would be converted to MS24693CC51. But why? I asked our tech. writers, who replied "Because that's the rule." Does anyone know the answer?

RE: part numbering in component maintenance manuals according to ATA

that may be the rule, but then it looks (IMHO) that the rule is an "ass". the "-" has meaning in the bolt part number (i assume the double C is a mistype, that the dash would be removed only ?). I can see that the "-" has special meaning in aircraft part definition (ie as an extension of the drawing number), but it seems ridiculous (again, IMHO) to apply this rule to vendor items (like screws).

but then, if people asked my opinion, and acted on it, i'd probably find the world a much more logical place.

Oops! Thank you, the double C is indeed a mistype.
