If a crack is found, replace the strut with a new, improved strut before further flight and repeat the inspection at intervals not to exceed 50 flight hours for that nacelle only. If no crack is found, repeat the inspection at intervals not to exceed 250 flight hours until the optional terminating action is accomplished.
