Narrative:

A form 337 was filed and received by the local FSDO office on mar/mon/04. The major repairs listed on the form were flush fuselage repairs at F.south. 334.25, F.south. 342.25, and rh gear well at aft gear sprocket. The data used was advisory circular 43.13-1B. The local FSDO notified me on mar/mon/04 of a possible violation due to the fact that the repairs were done in the pressurized area of the aircraft and that advisory circular 43.13.-1B was not applicable to repairs in these areas. Some of the factors that affected my judgement and the decision that was made are as follows: 1) the repairs were made by an a&P mechanic with extensive sheet metal experience. He elected to use advisory circular 43.13-1B and I questioned him about it. He said it was applicable at the time and I accepted it at that time. I had a vague memory of its exclusion from pressurized areas of the aircraft. I did not find anything that excluded these areas and so approved the repair. 2) failure to notice and read the very first page of advisory circular 43.13-1B that excluded its use for pressurized areas of the aircraft. 3) the a&P mechanic was a sheet metal instructor on the field, though did not offer FAA approved instruction. 4) no srm available at the time. 5) the aircraft was under extensive repair and was not in service.
