August 5,2013

NOTICES

Nineteenth Meeting: RTCA Special Committee 214/EUROCAE WG-78: Standards for Air Traffic Data Communication Services [FR DOC# 2013-18858] SUMMARY: The FAA is issuing this notice to advise the public of nineteenth meeting of RTCA Special Committee 214 to be held jointly with EUROCAE WG-78: Standards for Air Traffic Data Communication Services.

 

PROPOSED RULES

Airworthiness Directives; Thielert Aircraft Engines GmbH Reciprocating Engines [FR DOC# 2013-18797] SUMMARY: We propose to adopt a new airworthiness directive (AD) for all Thielert Aircraft Engines GmbH TAE 125-01 reciprocating engines. This proposed AD was prompted by a report of engine power loss due to engine coolant contaminating the engine clutch. The design of the engine allows the crankcase assembly opening to be susceptible to contamination from external sources. This proposed AD would require applying sealant to close the engine clutch housing (crankcase assembly) opening. We are proposing this AD to prevent in-flight engine power loss, which could result in loss of control of, and damage to, the airplane.

Airworthiness Directives; Eurocopter France (Eurocopter) Model Helicopters [FR DOC# 2013-18854] SUMMARY: We propose to adopt a new airworthiness directive (AD) for Eurocopter Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350C, AS350D, and AS350D1 helicopters. This proposed AD would require measuring the distance between the end of the main rotor collective pitch lever (collective) locking stud (locking stud) and the locking strip and repairing the locking stud if the clearance is insufficient. This proposed AD is prompted by a report that insufficient distance between the locking stud and the locking strip may cause the collective to become inadvertently locked in the low pitch (low) position. The proposed actions are intended to prevent the collective from becoming inadvertently locked in the low position and subsequent loss of control of the helicopter.

Airworthiness Directives; The Boeing Company Airplanes [FR DOC# 2013-18800] SUMMARY: We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737-600, -700, -800, -900, and -900ER airplanes modified by particular supplemental type certificates (STC). This proposed AD was prompted by reports of cracks found during inspections of the in-flight entertainment system radome assembly. This proposed AD would require repetitive detailed inspections for cracks in the radome assembly, and replacement of the radome if necessary. We are proposing this AD to detect and correct cracks in the radome assembly, which could result in the radome (or pieces) separating from the airplane and striking the tail, and consequently reducing the controllability of the airplane.

Airworthiness Directives; General Electric Company Turbofan Engines [FR DOC# 2013-18794] SUMMARY: We propose to adopt a new airworthiness directive (AD) for certain General Electric Company (GE) model GEnx-2B67 and GEnx-2B67B turbofan engines. This proposed AD was prompted by the original equipment manufacturer’s disclosure that certain critical rotating life-limited parts (LLPs) used in Boeing 747-8 flight tests had consumed more cyclic life than they would have in revenue flight cycles. These parts were then installed into engines and introduced into revenue service without adjustment to remaining cyclic life. This proposed AD would require a one-time adjustment to the cycle counts of those LLPs to account for the additional low cycle fatigue (LCF) life consumed during flight tests. We are proposing this AD to prevent the failure of critical rotating LLPs, uncontained engine failure, and damage to the airplane.

Proposed Amendment of Class E Airspace; Chariton, IA [FR DOC# 2013-18863] SUMMARY: This action proposes to amend Class E airspace at Chariton, IA. Decommissioning of the Chariton non-directional beacon (NDB) at Chariton Municipal Airport has made reconfiguration necessary for standard instrument approach procedures and for the safety and management of Instrument Flight Rules (IFR) operations at the airport.

Proposed Amendment of Class E Airspace; Wadena, MN [FR DOC# 2013-18861] SUMMARY: This action proposes to amend Class E airspace at Wadena, MN. Additional controlled airspace is necessary to accommodate new Standard Instrument Approach Procedures (SIAP) at Wadena Municipal Airport. The FAA is taking this action to enhance the safety and management of Instrument Flight Rules (IFR) operations for SIAPs at the airport. Geographical coordinates would also be updated.

Proposed Amendment of Class E Airspace; Washington, KS [FR DOC# 2013-18868] SUMMARY: This action proposes to amend Class E airspace at Washington, KS. Decommissioning of the Morrison non-directional beacon (NDB) at Washington County Memorial Airport has made reconfiguration necessary for standard instrument approach procedures and for the safety and management of Instrument Flight Rules (IFR) operations at the airport. Geographic coordinates would also be updated.
