to all, we deliver the kits, as an stc to md, as we would to any customer and have for years. it was our understanding that md would add to the tc. as we know, it was not and md asked us to get our stc recognized asap. normally that procedure is not a major undertaking, we hold various easa stc's, that were faa stc's, recognized by easa.
that said the door kit stc was a much older format, that easa would not accept "as is". therefore we have had to go back revise the stc, re submit to the faa, who then fwds the revision on to easa for review, who then asks for corrections, then we re submit the corrections on yet another revision, then back to faa, then on to easa. you get the idea and this is exactly where we are today, working fast as possible on another and hopefully the final revision.
