A mechanic found a “flat spot” on the L/H aileron crossover cable at the abrasion strip attached to the rib at wing station 71.19. Further observation found this cable beginning to fray. “The cause is the cable wearing on the abrasion strip. To solve this problem I think the abrasion strip should be lowered, or a pulley installed.” (The stainless steel cable P/N listed: 0510105-364. The abrasion strip P/N is 0523233-3. This defect was found during a 100-hour inspection. This submitter found similar cable discrepancies in two other aircraft—reported in last month’s Alerts. Search of the SDRS data base returns 25 cable related defects on 172 aircraft.)
