| 2014-28913 | Airworthiness Directives; Agusta S.p.A. (Agusta) Helicopters | Rule | We are revising Airworthiness Directive (AD) 2008-14-02 for Agusta Model AB139 and AW139 helicopters. AD 2008-14-02 required inspecting the fuselage frame to detect fatigue cracks which could lead to structural failure and subsequent loss of control of the helicopter. Since we issued AD 2008-14-02, Agusta developed a frame reinforcement modification, which supports extending the interval for inspecting the fuselage frame for a fatigue crack. This new AD requires inspecting the fuselage frame for a crack and reduces the applicability from AD 2008- 14-02 to exclude helicopters with the frame reinforcement modification. The actions of this AD are intended to detect a fatigue crack that could result in failure of the fuselage frame and subsequent loss of control of the helicopter. | 2014-12-12 | 2014 | 12 | https://www.federalregister.gov/documents/2014/12/12/2014-28913/airworthiness-directives-agusta-spa-agusta-helicopters | https://www.govinfo.gov/content/pkg/FR-2014-12-12/pdf/2014-28913.pdf | Transportation Department; Federal Aviation Administration | 492,159 | We are revising Airworthiness Directive (AD) 2008-14-02 for Agusta Model AB139 and AW139 helicopters.
