The recommended overhaul periods and necessary cross reference to the Airworthiness Limitations section of the manual must also be included. In addition, the applicant must include an inspection pro-gram that includes the frequency and extent of the inspections necessary to provide for the continued airworthiness of the rotorcraft.

FAR 27.A4 : Airworthiness Limitations section
The Instructions for Continued Airworthiness must contain a section titled Airwor-thiness Limitations that is segregated and clearly distinguishable from the rest of the document. This section must set forth each mandatory replacement time, structural ins-pectioninterval, andrelated structuralinspectionprocedure approved underSec.27.571. IftheInstructionsforContinuedAirworthiness consist of multipledocuments, the section required by this paragraph must be included in the principal manual. This section must contain a legible statement in a prominent location that reads : ”The Airworthiness Li-mitations section is FAA approved and speci.es maintenance required under Secs. 43.16 and[91.403] of theFederalAviationRegulationsunless an alternativeprogramhasbeen FAA approved.” Amdt. 27-24, E.. 8/18/90
