Model AB139 and AW139 helicopters with certain main rotor (M/R) rotating scissors installed. AD 2014-07-51 required repetitively inspecting the M/R rotating scissors for play of the lower half scissor spherical bearing (bearing) and removing the bearing if there was play beyond allowable limits. AD 2014-07-51 also required removing all affected bearings. AD 2014-07-51 was prompted by reports of certain bearings dislodging from certain M/R rotating scissors. This new AD retains the requirements of AD 2014-07-51, expands the applicability, and requires installing a special nut. These actions are intended to detect excessive play of the bearing and prevent failure of the M/R rotating scissors and subsequent loss of control of the helicopter.", "2014-11-28", 2014, 11, "https://www.federalregister.gov/documents/2014/11/28/2014-27995/airworthiness-directives-agusta-spa-helicopters", "https://www.govinfo.gov/content/pkg/FR-2014-11-28/pdf/2014-27995.pdf", "Transportation Department; Federal Aviation Administration", "492,159", "We are superseding Airworthiness Directive (AD) 2014-07-51 for AgustaWestland S.p.A.
