The MCAI describes the unsafe condition as installation of an unsuitable self-locking nut on the bell crank of the elevator push rod that can cause failure of the elevator, resulting in loss of control. We are issuing this AD to require actions to address the unsafe condition on these products.
Airworthiness Directives; Bombardier, Inc. Airplanes
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-102, -103, -106, -201, -202, -301, -311, and -315 airplanes. This AD was prompted by reports of the loss of the fixed frequency system, leading to the loss of power to the left and right buses and all systems serviced by these buses. This AD requires modification of the wiring and changes to existing airworthiness limitations. We are issuing this AD to prevent loss of the fixed frequency system, which could lead to loss of a number of the pilot's and co-pilot's flight instruments, in addition to other avionics systems.
Airworthiness Directives; Airbus Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A318-112, A319-111, A319-112, A319-115, A319-132, and A319-133 airplanes. This proposed AD was prompted by a report that a fastener, which connects the cargo door keel beam foot to the circumferential butt-strap and the section 13-14 lower shell panel, was not installed on airplanes during production. This proposed AD would require inspecting forward fuselage frame 24, stringer 39, right hand, to determine if the fastener is missing; measuring the hole dimensions of the five holes surrounding the missing fastener if necessary; and related investigative and corrective actions if necessary. We are proposing this AD to detect and correct the missing fastener, which could result in reduced structural integrity of the airplane.

Airworthiness Directives; Airbus Airplanes
We propose to adopt a new airworthiness directive (AD) for all Airbus Model A318, A319, A320, and A321 series airplanes. This proposed AD was prompted by reports that certain trimmable horizontal stabilizer actuators (THSA) were found with corrosion that affected the ballscrew lower splines between the tie-bar and screw-jack. This proposed AD would require repetitive inspections of the THSA; ballscrew integrity tests, if necessary; and replacement of affected THSAs. We are proposing this AD to detect and correct corrosion in the ballscrew lower splines, which, if the ballscrew ruptured, could lead to transmission of THSA torque loads from the ballscrew to the tie-bar, prompting THSA blowback, and possible loss of control of the airplane.
Airworthiness Directives; The Boeing Company Airplanes
We propose to supersede two existing airworthiness directives (AD) that apply to all The Boeing Company Model 767 airplanes. One AD currently requires a functional check of the shear rivets in all six elevator power control actuator (PCA) bellcrank assemblies to determine the condition of the shear rivets, and replacement or rework of the bellcrank assemblies if necessary. The other AD currently requires repetitive testing of the elevator control system to determine if an elevator PCA is rigged incorrectly, and follow-on actions if necessary. Since we issued those ADs, a terminating modification has been designed. This proposed AD would require an inspection to determine the part numbers and condition of the bellcrank assemblies; modification or replacement of the PCA bellcrank assembly, if necessary; and a repetitive functional test and mis-rig check, and corrective actions if necessary. We are proposing this AD to prevent continued operation with yielded or failed shear rivets in the elevator PCA bellcrank assemblies, and to prevent certain failures or jams in the elevator system from causing a hardover of the elevator surface, resulting in a significant pitch upset and possible loss of control of the airplane.
Airworthiness Directives; Gulfstream Aerospace LP (Type Certificate Previously Held by Israel Aircraft Industries, Ltd.) Airplanes
We propose to supersede an existing airworthiness directive (AD) that applies to all Gulfstream Aerospace LP (Type Certificate Previously Held by Israel Aircraft Industries, Ltd.) Model Gulfstream 100 airplanes, and Model Astra SPX and 1125 Westwind Astra airplanes. The existing AD currently requires amending the airplane flight manuals (AFMs) to include additional procedures for verifying complete closure and locking of the main entry door (MED). The existing AD also currently requires modifying the warning and caution lights panel (WACLP), changing the WACLP and MED wiring, changing the wiring harness connecting the MED to the WACLP, and revising the log of modification of the AFM if necessary. Since we issued that AD, we have determined that the compliance time must be revised to ensure the unsafe condition is addressed on low utilization airplanes. We have also removed one airplane from the applicability. We are proposing this AD to prevent incomplete closure of the MED, which may result in the door opening in flight and possible separation of the door, causing damage to the airplane structure and left engine by flying debris and objects.
Petition for Exemption; Summary of Petition Received

Neither publication of this notice nor the inclusion or omission of information in the summary is intended to affect the legal status of the petition or its final disposition.
Airworthiness Directives; Agusta S.p.A. and Bell Helicopter Textron Helicopters
We propose to adopt a new airworthiness directive (AD) for Agusta S.p.A. (Agusta) Model AB412 and AB412 EP, and Bell Helicopter Textron (Bell) Model 412, 412CF, and 412EP helicopters with certain DART Aerospace Ltd. (Dart) high gear aft crosstubes (crosstube) installed. This proposed AD would require adding a life limit of 10,000 landings to the crosstube and removing from service any crosstubes with more than 10,000 accumulated landings. This proposed AD is prompted by five separate reports of crosstube failures. The actions in this proposed AD are intended to prevent failure of the crosstube and subsequent collapse of the landing gear.
Airworthiness Directives; Agusta S.p.A. Helicopters
We propose to supersede an existing airworthiness directive (AD) for Agusta S.p.A. (Agusta) Model A109E helicopters that requires reducing the tail rotor (T/R) blade life limit, modifying a T/R hub and grip assembly, re-identifying two T/R assemblies, clarifying the never- exceed speed (Vne) limitation and reducing the inspection interval. Since we issued that AD, the manufacturer has redesigned a T/R grip bushing (bushing) that reduces the loads, which caused the T/R cracking, on the T/R blades. This action would require installing the new bushing and re-identifying the T/R hub-and-grip and hub-and-blade assemblies and require a recurring inspection of each bushing. The proposed actions are intended to prevent fatigue failure of a T/R blade and subsequent loss of control of the helicopter.
Airworthiness Directives; Robinson Helicopter Company
We propose to supersede an existing airworthiness directive (AD) for Robinson Helicopter Company (Robinson) Model R22, R22 Alpha, R22 Beta, R22 Mariner, R44, and R44 II helicopters with certain main rotor blades (blade) installed. The existing AD currently requires inspecting each blade at the skin-to-spar line for debonding, corrosion, a separation, a gap, or a dent and replacing any damaged blade with an airworthy blade. Since we issued that AD, a terminating action for the inspection requirements of that AD has been developed. The proposed actions are intended to detect debonding of the blade skin, which could result in blade failure and subsequent loss of control of the helicopter, and to correct the unsafe condition by replacing the main rotor blades with new blades that do not require the AD inspection.

We propose to adopt a new airworthiness directive (AD) for all Rolls-Royce (1971) Limited, Bristol Engine Division (RR) Viper Mk. 601- 22 turbojet engines. This proposed AD was prompted by a review carried out by RR of the lives of certain critical parts. This proposed AD would require reducing the life of these parts. We are proposing this AD to prevent life-limited part failure, damage to the engine, and damage to the airplane.
Policy Clarification on Charitable Medical Flights
The FAA is issuing this notice of policy to describe its policy for volunteer pilots operating charitable medical flights. Charitable medical flights are flights where a pilot, aircraft owner, and/or operator provides transportation for an individual or organ for medical purposes. This notice of policy is in response to Section 821 of Public Law 112-95, Clarification of Requirements for Volunteer Pilots Operating Charitable Medical Flights.
Airworthiness Directives; Embraer S.A. Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Embraer S.A. Model ERJ 170 and ERJ 190 airplanes. This proposed AD was prompted by reports of chafing between the auxiliary power unit (APU) electronic starter controller (ESC) power cables and the airplane tail cone firewall. This proposed AD would require a detailed inspection for damage to the insulation and inner conductors of the APU ESC power cables, installing new grommet support in the tail cone firewall, and corrective actions if necessary. We are proposing this AD to detect and correct damage to the APU ESC power cable harness, which if not corrected, could result in reduced structural integrity of the fuselage and empennage in the event of fire penetration through the firewall.
Airworthiness Directives; The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 787-8 airplanes. This emergency AD was sent previously to all known U.S. owners and operators of these airplanes. This AD requires modification of the battery system, or other actions. This AD was prompted by recent incidents involving lithium ion battery failures that resulted in release of flammable electrolytes, heat damage, and smoke. We are issuing this AD to correct damage to critical systems and structures, and the potential for fire in the electrical compartment.
Unmanned Aircraft System Test Site Program
On February 14, 2012, Congress mandated that the FAA, coordinating with the National Aeronautics and Space Administration and the Department of Defense, develop a test site program for the integration of unmanned aircraft systems in to the National Airspace System. The overall purpose of this test site program is to develop a body of data and operational experiences to inform integration and the safe operation of these aircraft in the National Airspace System. This proposed rule announces the process by which the FAA will select the test sites for the program and also solicits comments on the FAA's proposed approach for addressing the privacy questions raised by the public and Congress with regard to the operation of unmanned aircraft systems within the test site program.
Interest in Restructure of Rotorcraft Airworthiness Standards
The Federal Aviation Administration (FAA) is requesting comments and information on the public's interest in restructuring the rotorcraft airworthiness standards of normal category rotorcraft and transport category rotorcraft. Specifically, the agency is seeking comments on whether to change the existing applicability standards for maximum weight and number of passenger seats for either or both types of rotorcraft, or whether to consider other approaches for determining applicability. The FAA is soliciting public input because of some rotorcraft community interest in increasing the 7,000 pound maximum weight limit for the modern normal category rotorcraft and because there may be recommendations for new approaches to make the rotorcraft airworthiness standards more efficient and adaptable to future technology. This action is part of an effort to develop recommendations for possible FAA rulemaking action.
Proposed Modification of Class D and Class E Airspace; Pueblo, CO
This action proposes to modify Class D airspace and the Class E airspace areas at Pueblo Memorial Airport, Pueblo, CO. Controlled airspace is necessary to accommodate aircraft using VHF Omni- Directional Radio Range/Distance Measuring Equipment (VOR/DME) standard instrument approach procedures at Pueblo Memorial Airport. The FAA is proposing this action to enhance the safety and management of Instrument Flight Rules (IFR) operations in the vicinity of the Pueblo Memorial Airport. This action also would make an adjustment to the geographic coordinates of the airport.
Amendment of Class E Airspace; Casper, WY
This action modifies Class E airspace areas at Casper, Natrona County International Airport, Casper, WY, to facilitate vectoring of Instrument Flight Rules (IFR) traffic from en route airspace to the airport. Decommissioning of the Muddy Mountain VOR Omnidirectional Range Tactical Air Navigation (VORTAC) has made reconfiguration necessary for the safety and management of aircraft operations at the airport.
Fifty Eighth Meeting: RTCA Special Committee 186, Automatic Dependent Surveillance-Broadcast (ADS-B)
The FAA is issuing this notice to advise the public of the fifty eighth meeting of the RTCA Special Committee 222, Inmarsat AMS(R)S.
Airworthiness Directives; The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-200, -200C, -300, -400, and -500 series airplanes. This AD was prompted by reports of cracks in the skin and surrounding structure under the number 3 very high frequency (VHF) antenna on the lower external surface of the airplane at buttock line 0.0, aft of the main landing gear wheel well. This AD requires inspecting for cracking and corrosion under the number 3 VHF antenna, and corrective actions if necessary; and, for certain airplanes, replacing bonded skin panels with solid skin panels if not previously accomplished. This AD also provides an optional preventive modification (which would terminate the inspection requirements for certain airplanes). We are issuing this AD to detect and correct cracks and corrosion of the skin and surrounding structure under the number 3 VHF antenna, which could result in separation of the antenna from the airplane, and rapid depressurization of the airplane.
Airworthiness Directives; Rolls-Royce plc Turbofan Engines
We are superseding an existing airworthiness directive (AD) for all Rolls-Royce plc (RR) RB211-524 series turbofan engines. That AD currently requires removal and repair of certain thrust reverser units (TRUs) prior to reinstallation. This AD requires the same actions for an expanded population of TRUs and extends the compliance time for repairing certain TRUs. This AD was prompted by additional engineering evaluation of TRUs, as a result of a translating cowl gearbox stubshaft failure and subsequent repair. We are issuing this AD to prevent failure of the attachment rivets, which may result in release of the TRU from the engine.
Airworthiness Directives; Reims Aviation S.A. Airplanes
We are adopting a new airworthiness directive (AD) for Reims Aviation S.A. Model F406 airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued 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 improper material used in nose landing gear (NLG) attachment brackets could lead to failure of the NLG bracket with consequent damage to the airplane while landing. We are issuing this AD to require actions to address the unsafe condition on these products.
