English term

ex a check

English Tech/Engineering Aerospace / Aviation / Space Aircraft Industry
The aircraft shall be ex a 4C/6year check in “block” format, including all inspections with intervals of 6,000 flight hours, 4,500 cycles, 20 months and all lesser inspection intervals, where relevant, the work-scope and intervals (calendar and/or hourly) shall not be less than those prescribed by the then current Manufacturer’s Maintenance Planning Document.

This term is used in an Aircraft Lease Agreement, and has only two matches in google:

http://google.brand.edgar-online.com/EFX_dll/EDGARpro.dll?Fe...

As far as I remember "ex" is "without" or "excluding", but detailed information of the main and subsequent checks after the "ex a check" is fairly misleading.

"ex" in this context means exactly the same as it means in the terms "ex-works", "ex-factory" and similar. Meaning that the product has just been made, or just been through such as an overhaul (railway and road vehicles). So the aircraft is fully certified with C of A.

The "a" in your posting is a little misleading, as the "4C/6-year" was omitted, and that was the important element. It wasn't "a check", but a very specific check.

The designation of the different check/maintenance levels can be found here: http://www.fzt.haw-hamburg.de/pers/Scholz/arbeiten/VortragDe...

Although I haven´t checked the details of this presentation you can have a short glimpse on the "naming" of each check. The "D" check is more thoroughly than the "A" check of the short visual check between two flights. So just would like to back the answer of Tony M with this additional reference provided.

David Moore (X) Sep 12, 2012:
@ Tony: Post as an answer, and I'll back it. You are right - the same terms are also used in the railway industry.
Tony M Sep 12, 2012:
ex can also meaning 'coming out of', and I think that is the meaning here: the a/c will have 'come from'

Cf. 'a flight ex London' = 'flight coming from London'

coming out of / from / after

In many fields, 'ex' also has the sense of 'coming out of, 'or from', which could be applicable in your case.

Thanks, David!
agree Martin Riordan : Or "having done" in this case. The internet confirms that this is a specific civil aircraft inspection.
