Narrative:
As a designated inspector for a part 145 composite repair station; I performed a florescent penetrant inspection on a vortex control device (vcd) as called out in boeing component maintenance manual (cmm). I had received training in the use of a florescent penetrant kit as well as utilized the included instructions provided with the kit. I exercised due diligence in performing the inspection and I am confident that the result of 'no damage found' was correct. However; in review of FAA memorandum subject: information: qualification standards for non-destructive testing dated july 2007; I have become aware that I was not qualified to perform the referenced inspection as I have not been trained to any standard acceptable to meet the FAA requirements. Again I have no doubt whatsoever as to the proficiency of the test I performed or to the safe operation of the part in question;
