B. Cracked sliders are to be replaced prior to further flight, except that if a slider is cracked or missing pieces exist at only one attach bolt hole location, as noted in Boeing Alert Service Bulletin No. 727-57-A147, the slider may remain in service but must be inspected at intervals not to exceed 50 landings and must be replaced within 200 flights from detection of the initial cracking.
