## Summary

We propose to revise airworthiness directive (AD) 2014-12-11 for Sikorsky Aircraft Corporation (Sikorsky) Model S-92A helicopters. AD 2014-12-11 currently requires revising the Rotorcraft Flight Manual (RFM) to include the appropriate operating limitations for performing Class D external load-combination operations. As published, AD 2014-12- 11 references an incorrect date for Revision No. 12 of Sikorsky RFM SA S92A-RFM-003, Part 1. This proposed AD would correct the error while retaining the requirements of AD 2014-12-11. These proposed actions are intended to require appropriate operating limitations to allow operators to perform Class D external load-combination operations, including human external cargo, in this model helicopter that now meets the Category A performance standard.
