We had one guy that worked as a ramper with me at XJT that was also a licensed A&P. To take it one step further, he even works part time for the contract mx company XJT uses in MEM. However, he was smart, and he wouldn't fix or sign off on a repair that was asked to be made while he was working as a ramper. His reasoning was that he wasn't acting in the capacity as an A&P at the time, and he thought it would look bad if something went wrong and the FAA got involved. Possibly too cautious, but I agreed with him. Although the time he WAS acting as A&P and was called out to fix a valve on a CRJ engine (Mesa contract), we really got on him since it took him about two hours to find a part. He wound up "borrowing" it from Mesaba.
