Membership in the National Parks Overflights Advisory Group Aviation Rulemaking Committee
The Federal Aviation Administration (FAA) and the National Park Service (NPS) are inviting interested persons to apply to fill two upcoming openings on the National Parks Overflights Advisory Group (NPOAG) Aviation Rulemaking Committee (ARC). The upcoming openings will represent commercial air tour operator and environmental interests, respectively. The selected members will serve 3-year terms.
Airworthiness Directives; Airbus Helicopters
We propose to adopt a new airworthiness directive (AD) for certain Airbus Helicopters Model AS332L2 and EC225LP helicopters. This proposed AD would require installing a cut-out for the left-hand (LH) and right-hand (RH) rail support junction profiles and inspecting splices, frame 5295, and related equipment for a crack. This proposed AD is prompted by reports of cracks on frame 5295 and on splices installed to prevent those cracks. The proposed actions are intended to detect a crack in frame 5295, which could lead to loss of the helicopter frame's structural integrity and consequently, loss of helicopter control.
Airworthiness Directives; Sikorsky Aircraft Corporation Helicopters
We are adopting a new airworthiness directive (AD) for certain Sikorsky Aircraft Corporation (Sikorsky) Model S-76A, S-76B, and S-76C helicopters. This AD requires inspecting the main gearbox (MGB) lower housing jet bores for leaks, paint or caulk blistering, and liner protrusion. This AD was prompted by several reports of MGB low oil pressure warnings which were determined to be the result of unsecured jet bore liners that had protruded. The actions are intended to prevent failure of the MGB from loss of oil, which could result in subsequent loss of control of the helicopter.
Airworthiness Directives; Piper Aircraft, Inc.
We are adopting a new airworthiness directive (AD) for certain Piper Aircraft, Inc. Model PA-44-180 and PA-44-180T airplanes. This AD requires an inspection and, if necessary, modification of the emergency gear extension cable. This AD was prompted by a report of a misrouted emergency gear extension cable. We are issuing this AD to correct the unsafe condition on these products.
