This new AD retains the actions required by AD 90-26-12, reflects that the type certificate (TC) for this model helicopter has been transferred to Erickson Air-Crane Incorporated (Erickson), and expands the applicability to include the similar Erickson Model S-64F helicopters. This AD is prompted by a need to expand the applicability to include Model S-64F helicopters and clarify the applicable main rotor blades by part number. These actions are intended to detect a crack in the main rotor blade and prevent blade separation and subsequent loss of control of the helicopter.", "2013-11-22", 2013, 11, "https://www.federalregister.gov/documents/2013/11/22/2013-27635/airworthiness-directives-erickson-air-crane-incorporated-helicopters-type-certificate-previously", "https://www.govinfo.gov/content/pkg/FR-2013-11-22/pdf/2013-27635.pdf", "Transportation Department; Federal Aviation Administration", "492,159", "We are superseding airworthiness directive (AD) 90-26-12 for Sikorsky Aircraft Corporation (Sikorsky) Model S-64E helicopters.
