## Abstract

We are adopting a new airworthiness directive (AD) for the Sikorsky Aircraft Corporation (Sikorsky) Model S-92A helicopter. This AD requires revising the Rotorcraft Flight Manual (RFM) to include the appropriate operating limitations for performing Class D external load- combination operations. This AD was prompted by an inaccurate RFM provision, which was approved without appropriate limitations for this model helicopter for carrying Class D external rotorcraft-load combinations, including human external cargo (HEC). The actions are intended to require appropriate operating limitations to allow operators to perform Class D external load-combination operations, including HEC, in this model helicopter that now meets the Category A performance standard.
