AB 2010:2/11-2

ASRS received a report from a maintenance technician who indicated the parts manual and maintenance procedures for the PA-28 were lacking information regarding wing and false spar installation. The reporter stated that after completing a repair replacement of the right wing false spar, the owner called reporting a crack on the upper right wing skin. The technician indicated that he knew immediately what caused the crack, either the structural attach angle had failed or had not been installed, as was discovered in this case. The reporter alleged that he had seen similar cracks before on this type aircraft, suggesting the Piper maintenance and parts manuals need more pictorial and reference information.
