(d) If damage to the fin ribs is found that exceeds the permissible limits specified in the BAC 1-11 Alert Service Bulletin No. 55-A-PM 2730, Issue 2, or later ARB-approved issue, or an FAA-approved equivalent, repair the damaged parts in accordance with BAC 1-11 Structural Repair Manual or BAC 1-11 Service Bulletin No. 55-PM-2742, or later ARB-approved issue, or an FAA-approved equivalent, before further flight.

(e) The repetitive inspections required by paragraphs (a) and (c) of this AD may be discontinued for any one of the fin rib assemblies numbers 2, 3, 4, 5, or 6 for a period of 4,000 hours' time in service after that fin rib assembly has been modified in accordance with Part (c) of BAC 1-11 Service Bulletin No. 55-PM-2742, or an FAA-approved equivalent.
