Implementation of Legislative Categorical Exclusion for Environmental Review of Performance Based Navigation Procedures
The FAA is extending the comment period on its notice regarding the Implementation of Legislative Categorical Exclusion for Environmental Review of Performance Based Navigation Procedures that was published on August 19, 2014.
Policy on the Non-Aeronautical Use of Airport Hangars; Extension for Comments
The Federal Aviation Administration (FAA) has recently issued a notice of proposed policy. Significant interest among the aviation community, industry representatives, and congressional representatives has compelled the FAA to extend the comment period by 30 days. FAA will consider comments submitted to the docket by Monday, October 6, 2014.
Airworthiness Directives; Rolls-Royce plc Turbofan Engines
We propose to supersede airworthiness directive (AD) 2013-15- 10 that applies to certain Rolls-Royce (RR) RB211 turbofan engines. AD 2013-15-10 requires inspecting the intermediate-pressure compressor (IPC) rotor shaft rear balance land for cracks. This AD eliminates a terminating action, expands one inspection and eliminates others. This proposed AD would require inspecting the IPC rotor shaft rear balance land for cracks and eliminate certain other inspections. We are proposing this AD to detect cracking on the IPC rotor shaft rear balance land, which could lead to uncontained engine failure and damage to the airplane.
Airworthiness Directives; Lycoming Engines Reciprocating Engines
We propose to adopt a new airworthiness directive (AD) for certain serial number Lycoming Engines reciprocating engines. This proposed AD was prompted by events of propeller governor shaft set screws coming loose due to improper installation, which could result in engine oil loss, damage to the engine, and damage to the airplane. This proposed AD would require application of Loctite 290, or equivalent, to the threads of the propeller governor shaft set screw at each installation of the set screw in addition to the peening of crankcase hole threads. We are proposing this AD to prevent the propeller governor shaft set screw from coming loose, causing damage to the engine, and damage to the airplane.
Modification and Revocation of Air Traffic Service (ATS) Routes; Northcentral United States
This action modifies two jet routes and three VOR Federal airways and removes three jet routes in the north central United States. The FAA is taking this action due to the scheduled decommissioning of the Peck, MI, VHF Omnidirectional Range (VOR) navigation aid (NAVAID), which provides navigation guidance for portions of the affected routes. The amendments for one jet route (J- 38) and one VOR Federal airway (V-337) that were addressed in the notice of proposed rulemaking (NPRM) are withdrawn from this final rule as they are being amended in a separate rulemaking action. This action promotes flight safety and the efficient management of aircraft operating within the National Airspace System (NAS).
