NOTICES
Noise Exposure Map Notice for Bob Hope Airport, Burbank, California [FR DOC# 2013-24991] SUMMARY: The FAA announces its determination that the noise exposure maps submitted by Burbank-Glendale- Pasadena Airport Authority, for Bob Hope Airport under the provisions of 49 U.S.C. 47501 et. seq (Aviation Safety and Noise Abatement Act) and 14 CFR Part 150 are in compliance with applicable requirements.
PROPOSED RULES
Airworthiness Directives; the Boeing Company Airplanes [FR DOC# 2013-25134] SUMMARY: We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 777-200, -200LR, -300, and -300ER series airplanes. This proposed AD was prompted by reports of severe corrosion on bonding jumpers installed on the flight control surfaces. This proposed AD would require repetitive bonding jumper inspections for corrosion, sealant disbond, and insufficient sealant coverage, and corrective
actions if necessary. This proposed AD also specifies an optional action of doing an inspection for corrosion damage of the bonding brackets, and corrective actions if necessary, which would terminate the repetitive inspections. For certain airplanes, this proposed AD would also require installing certain bonding jumpers and related ground clips and fasteners to the elevators, horizontal stabilizers, rudder, and vertical fin, removing certain bonding jumpers and installing new bonding jumpers, and replacing single-tabbed brackets with two-tabbed brackets. We are proposing this AD to detect and correct corrosion on bonding jumpers installed on the flight control surfaces, which, in
the event of a lighting strike, could damage the actuator control electronics (ACEs) and result in the loss of the ability to command individual flight control surfaces or cause uncommanded motion of individual flight control surfaces.
Airworthiness Directives; Costruzioni Aeronautiche Tecnam srl Airplanes [FR DOC# 2013-25137] SUMMARY: We propose to adopt a new airworthiness directive (AD) for Costruzioni Aeronautiche Tecnam srl Model P2006T airplanes. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as cracks of the nose landing gear (NLG) lower link. We are issuing this proposed AD to require actions to address
the unsafe condition on these products.
Special Conditions: Embraer S.A., Model EMB-550 Airplanes; Flight Envelope Protection: Normal Load Factor (g) Limiting [FR DOC# 2013-25204] SUMMARY: This action proposes special conditions for the Embraer S.A. Model EMB-550 airplane. This airplane will have a novel or unusual design feature associated with an electronic flight control system that prevents the pilot from inadvertently or intentionally exceeding the positive or negative airplane limit load factor. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These proposed special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
RULES
Airworthiness Directives; AgustaWestland S.p.A. (Agusta) Helicopters [FR DOC# 2013-24937] SUMMARY: We are adopting a new airworthiness directive (AD) for Agusta Model A109A, A109A II, A109C, A109E, A109K2, A109S, AW109SP, A119, and AW119 MKII helicopters. The emergency AD was sent previously to all known U.S. owners and operators of these helicopters. This AD requires, before further flight, inspecting certain Thomas coupling nuts on the tail rotor drive shaft line for a crack and replacing
all the nuts if any nut is cracked. Also this AD requires replacing all affected Thomas coupling nuts within 10 hours time-in-service (TIS) or 30 days, whichever occurs first. This AD was prompted by two incidents of cracking on the nuts that connect the flexible disc coupling (Thomas coupling) with the splined adapter on the tail rotor drive shaft. We are issuing this AD to correct the unsafe condition on these helicopters.
Airworthiness Directives; Hamilton Standard Division and Hamilton Sundstrand Corporation Propellers [FR DOC# 2013-25108] SUMMARY: The FAA is correcting an airworthiness directive (AD) that published in the Federal Register. That AD applies to all Hamilton Standard Division model 6/5500/F and 24PF and Hamilton Sundstrand Corporation model 14RF, 14SF, 247F, and 568F series propellers. A maintenance manual number in paragraph (g) of the Compliance section is incorrect. This document corrects that error. In all other respects, the original document remains the same.
Airworthiness Directives; Eurocopter France (Eurocopter) Helicopters [FR DOC# 2013-24816] SUMMARY: We are adopting a new airworthiness directive (AD) for Eurocopter Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350C, AS350D, AS350D1, AS355E, AS355F, AS355F1, AS355F2, AS355N, and AS355NP helicopters. This AD requires certain inspections of each tail rotor pitch horn assembly (pitch horn) for a crack, and if there is a crack, before further flight, replacing the pitch horn with an airworthy pitch horn. This AD is prompted by a report of a crack in the yoke of a pitch horn. These
actions are intended to detect a crack in the pitch horn to prevent failure of the pitch horn, loss of the anti-torque function, and subsequent loss of control of the helicopter.
Airworthiness Directives; the Boeing Company Airplanes [FR DOC# 2013-24812] SUMMARY: We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 747-8F and 747-8 series airplanes. This AD requires a detailed inspection of the power control actuator (PCA) installation to determine if a bushing is installed, a general visual inspection between the horizontal stabilizer rear spar and the elevator front spar and between certain stabilizer stations for defects and damage, and corrective actions if necessary. This AD was prompted by a report of unusual noise coming from the left inboard elevator during a functional check of the ram air turbine system, and a
determination that a bushing was not installed. We are issuing this AD to detect and correct non- installation of bushings. If the bushings are not present, the stiffness of the load path will be decreased, which will cause wear of adjacent parts and increased freeplay of the elevator surfaces. Freeplay that exceeds acceptable limits could result in divergent flutter for certain maneuvers, which could lead to loss of controllability of the airplane.
Airworthiness Directives; Bell Helicopter Textron, Inc. (Bell) Helicopters [FR DOC# 2013-24961] SUMMARY: We are superseding Airworthiness Directive (AD) 2009-05-09 for Bell Model 412, 412CF, and 412EP helicopters. AD 2009-05-09 required reidentifying each affected part-numbered main rotor yoke (yoke) on its data plate, reducing the retirement life of the reidentified yoke, and revising the Airworthiness Limitations section of the maintenance manual or the Instructions for Continued Airworthiness (ICAs) accordingly. This new AD retains the requirements of AD 2009-05-09 with the exception of the P/N marking location. This AD was prompted by fatigue analysis that shows the
retirement life should be reduced on certain yokes. We are issuing this AD to correct the unsafe condition on these helicopters.
Amendment of Class D Airspace; Kwajalein Island, Marshall Islands, RMI [FR DOC# 2013-24976] SUMMARY: This action amends the Kwajalein Island Class D airspace description by amending the geographic coordinates for Bucholz Army Airfield (AAF), Kwajalein Island, Marshall Islands, RMI. The Bucholz AAF geographic coordinates information was updated in the Kwajalein Island Class E airspace descriptions in 2011, but was inadvertently overlooked in the Kwajalein Island Class D airspace description. This action ensures the safety of aircraft operating in the Kwajalein Island airspace area. This is an administrative action and does not affect the operating requirements of the
airspace.
Modification of Class B Airspace; Minneapolis, MN [FR DOC# 2013-24983] SUMMARY: This action amends the Minneapolis, MN, Class B airspace area to contain large turbine-powered aircraft conducting published instrument procedures at the Minneapolis-St. Paul International Airport (MSP), MN, within Class B airspace. The FAA is taking this action to ensure containment of aircraft being vectored to and conducting dual Simultaneous Instrument Landing System (SILS) approaches to parallel Runways 12L/R and 30L/R; aircraft being vectored to and conducting approaches to Runway 35; and, aircraft
being re-sequenced from approaches to Runway 35 to approaches to Runway 30L. This action supports the FAA’s national airspace redesign goal of optimizing terminal and en route airspace areas to enhance safety, improving the flow of air traffic, and reducing the potential for near midair collision in terminal airspace areas.
Modification of Restricted Areas R-6901A & R-6901B; Fort McCoy, WI [FR DOC# 2013-25203] SUMMARY: This action amends Restricted Areas R-6901A and R-6901B, Fort McCoy, WI, to accurately identify the segment of Wisconsin State Highway 21 used to identify the shared boundary between the restricted areas. The geographic coordinates contained in the existing legal descriptions for defining the highway actually plot south of it. This is an administrative correction to accurately define the geographic coordinates where the restricted area boundaries intercept Wisconsin State Highway 21 and does not affect the overall restricted area boundaries; designated altitudes; times of designation;
or activities conducted within the restricted areas.
