Notice of Meeting of the National Parks Overflights Advisory Group Aviation Rulemaking Committee
The Federal Aviation Administration (FAA) and the National Park Service (NPS), in accordance with the National Parks Air Tour Management Act of 2000, announce the next meeting of the National Parks Overflights Advisory Group (NPOAG) Aviation Rulemaking Committee (ARC). This notification provides the date, location, and agenda for the meeting. Date and Location: The NPOAG ARC will meet on March 5, 2015. The meeting will take place in Room S230DE in the South Concourse of the Orange County Convention Center at 9899 International Drive Orlando, FL 32819. The meeting will be held from 8:30 a.m. to 4:30 p.m. on March 5, 2015. This NPOAG meeting will be open to the public.
Airworthiness Directives; Lycoming Engines Reciprocating Engines (Type Certificate Previously Held by Textron Lycoming Division, AVCO Corporation)
We propose to adopt a new airworthiness directive (AD) for certain Lycoming TIO-540-AJ1A reciprocating engines. This proposed AD was prompted by several reports of cracked engine exhaust pipes. This proposed AD would require inspection of the engine exhaust pipes for cracks and replacement of the turbocharger mounting bracket. We are proposing this AD to prevent failure of the exhaust system due to cracking, which could lead to uncontrolled engine fire, harmful exhaust gases entering the cabin resulting in crew incapacitation, and damage to the airplane.
Airworthiness Directives; Airbus Helicopters (Previously Eurocopter France) Helicopters
We are superseding Airworthiness Directive (AD) 2013-19-19 for certain Eurocopter France Model AS332C, AS332L, AS332L1, AS332L2, and EC225LP helicopters. AD 2013-19-19 required replacing certain serial- numbered main gearbox (MGB) bevel gear vertical shafts and inspecting and replacing, if necessary, each MGB bevel gear vertical shaft (shaft). This new AD requires the same actions as AD 2013-19-19 but corrects an error in the term used to identify an inspection qualification and updates the type certificate holder's name. This AD is prompted by two incidents of emergency ditching after warning indications of loss of MGB oil pressure. These actions are intended to detect a cracked shaft, which could result in loss of MGB oil pressure, loss of the MGB lubrication system, and subsequent loss of control of the helicopter.
Airworthiness Directives; Rolls-Royce Corporation Turboprop and Turboshaft Engines
We are superseding airworthiness directive (AD) 2012-14-06 for certain Rolls-Royce Corporation (RRC) 250-C20, -C20B, and -C20R/2 turboshaft engines. AD 2012-14-06 required a one-time visual inspection and fluorescent-penetrant inspection (FPI) on certain 3rd-stage and 4th-stage turbine wheels for cracks in the turbine blades. This new AD replaces the one-time visual inspection and FPI with repetitive visual inspections and FPIs. This AD also adds certain engine models to the applicability. This AD was prompted by the determination that the one- time inspections required by AD 2012-14-06 should be changed to repetitive inspections. We are issuing this AD to prevent failure of 3rd-stage and 4th-stage turbine wheel blades, which could cause engine failure and damage to the aircraft.
