(AFE), Rotorcraft Development Corporation (RDC), and San Joaquin Helicopters (SJH) Model OH-58A, OH- 58A+, and OH-58C helicopters. AD 2012-14-11 currently requires inspecting the main rotor mast (mast) for a crack. Since we issued AD 2012-14-11, we have determined that the area of the mast requiring inspection should be expanded and repetitive inspections of the mast should be accomplished. This proposed AD would expand the area of the mast that requires an inspection for a crack and would require repetitive inspections of the mast. The proposed actions are intended to prevent failure of the mast and subsequent loss of control of the helicopter. 79 FR 31233 https://www.govinfo.gov/app/details/FR-2014-06-02/2014-12737 2014-12737 fr02jn14-10 RIN 2120-AA64 4910-13-P Docket No. FAA-2014-0337 Directorate Identifier 2013-SW-029-AD https://www.govinfo.gov/app/details/FR-2014-06-02/2014-12737 https://www.govinfo.gov/content/pkg/FR-2014-06-02/html/2014-12737.htm https://www.govinfo.gov/content/pkg/FR-2014-06-02/pdf/2014-12737.pdf Air Transportation Aircraft Aviation Safety Incorporation by Reference Safety 4 p. 31233 31236 79 FR 31233 Title 14 Part 39 14 CFR Part 39 RIN 2120-AA64 Airworthiness Directives; Various Restricted Category Helicopters; Federal Register Vol. 79, Issue PRORULE 2014-12737 DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 2014-08-01 Docket No. FAA-2014-0337 Directorate Identifier 2013-SW-029-AD 4910-13-P 2014-12737 Notice of proposed rulemaking (NPRM).

We propose to supersede airworthiness directive (AD) 2012-14- 11 for Arrow Falcon Exporters, Inc. (AFE), Rotorcraft Development Corporation (RDC), and San Joaquin Helicopters (SJH) Model OH-58A, OH- 58A+, and OH-58C helicopters.

This proposed AD would expand the area of the mast that requires an inspection for a crack and would require repetitive inspections of the mast. The proposed actions are intended to prevent failure of the mast and subsequent loss of control of the helicopter.
