If one of these stabilizers/ assemblies is installed, replace prior to further flight.

(b) Alternative inspections, modifications, or other actions which provide an equivalent method of compliance may be used when approved by the Manager, Helicopter Certification Branch, Southwest Region, Federal Aviation Administration, Fort Worth, Texas 76193-0170.
