Require operators of Boeing 757 airplanes to conduct a one-time visual inspection of the upper wing fixed trailing edge panel support beam clips for cracks, proper orientation, and spacers, and to replace cracked clips and reinstall any clips that are improperly oriented or that lack spacers, in accordance with Boeing Service Bulletin 757-57-0027, Revision 2, dated November 14, 1991.

Require operators to report any cracked clips found during the one-time inspection, as requested in Safety Recommendation A-08-22, as well as the part number and orientation of the clips relative to the wing rear spar vertical stiffeners and whether spacers were present; then analyze this information to determine if repetitive inspections are required.
