Narrative:
On mar/sun/03, I signed an FAA form 337 on the repair on an at-6D, for repairs on left and right wings. The shop I work for subcontracted the wing repairs out. On the next annual, the wings were inspected. Discrepancies were noted that included work that was not acceptable by AC43, 13-1B, 3 ribs that were supposed to be changed were instead repaired. The 337 stated that the leading edges had been primed with epoxy primer and painted with silver impon when in fact only the exterior had. Also, the workmanship on the leading edges and the rib repairs was done very poorly. By not thoroughly reading the 337 before I signed it, I made a great error in judgement. From now on, I will insure that the work is done in accordance with AC43.13-1B before I sign another form 337. I feel the repairs did not endanger the aircraft or owner, the aircraft flew 50+ hours, so I feel that there was no danger of it coming apart -- just poor workmanship.

Title: A TECHNICIAN RPTS SIGNING AN FAA FORM 337 FOR MAJOR REPAIR WORK TO A NORTH AMERICAN T6 THAT WAS CONTRACTED OUT. THE WORK APPEARED SUBSTANDARD ON A FOLLOW-UP ANNUAL INSPECTION.
Narrative: ON MAR/SUN/03, I SIGNED AN FAA FORM 337 ON THE REPAIR ON AN AT-6D, FOR REPAIRS ON L AND R WINGS. THE SHOP I WORK FOR SUBCONTRACTED THE WING REPAIRS OUT. ON THE NEXT ANNUAL, THE WINGS WERE INSPECTED. DISCREPANCIES WERE NOTED THAT INCLUDED WORK THAT WAS NOT ACCEPTABLE BY AC43, 13-1B, 3 RIBS THAT WERE SUPPOSED TO BE CHANGED WERE INSTEAD REPAIRED. THE 337 STATED THAT THE LEADING EDGES HAD BEEN PRIMED WITH EPOXY PRIMER AND PAINTED WITH SILVER IMPON WHEN IN FACT ONLY THE EXTERIOR HAD. ALSO, THE WORKMANSHIP ON THE LEADING EDGES AND THE RIB REPAIRS WAS DONE VERY POORLY. BY NOT THOROUGHLY READING THE 337 BEFORE I SIGNED IT, I MADE A GREAT ERROR IN JUDGEMENT. FROM NOW ON, I WILL INSURE THAT THE WORK IS DONE IN ACCORDANCE WITH AC43.13-1B BEFORE I SIGN ANOTHER FORM 337. I FEEL THE REPAIRS DID NOT ENDANGER THE ACFT OR OWNER, THE ACFT FLEW 50+ HRS, SO I FEEL THAT THERE WAS NO DANGER OF IT COMING APART -- JUST POOR WORKMANSHIP.
