What is EASA Part 21 G

[CHRSCLLNGS]

Morning all Covers
We have the potential for some new business, and the potential customer has asked whether we are EASA Part 21 G approved.
Obviously we are not, seeing as this is the first time I've ever heard about it. I have flicked around on the internet looking for a bit of background, but as always, the best place to look is on here with you guys and gals.
Can anybody help me with a bit of info on what the thing actually is and what it involves to implement it. As I implemented AS9100 last year, I can see this being my new project in the near future.
Any help would be gratefully appreciated.
Thanks all
Chris

It's a production organization approval:

A company holding Production Organisation Approval (POA), has the approval to built and certify aircraft parts when a DOA POA agreement is in place. A part built for an aircraft can be certificated with an EASA Form One as approved for a particular aircraft type once is has been installed as prototype to an aircraft and has been certificated by a Design Organisation with a Minor Change Approval, a Supplemental Type Certificate (STC) or a Type Certificate (TC).

I am not familiar with it as it is not a requirement for our company although I suspect it is similar to our FAR Part 21 G requirements. You should be able to find everything you need on the EASA website.
