Proposed Establishment of Restricted Area R-2306F; Yuma Proving Ground, AZ.
This action proposes to establish restricted area R-2306F in the vicinity of Laguna Army Airfield at Yuma Proving Ground, AZ. The proposed restricted area would allow the Department of the Army to maximize the existing fixed infrastructure to support hazardous test programs and segregate these activities from non-participating aircraft at Yuma Proving Ground (YPG). These programs include ground and airborne testing of non-eye-safe lasers, high energy radars and the development of unproven weapons systems. The restricted airspace would ensure the safe testing and evaluation of these programs without impacting non-participating aircraft and the general public.
Airworthiness Directives; CFM International, S.A. Turbofan Engines Modified by Supplemental Type Certificate SE00034EN
We are superseding airworthiness directive (AD) 2013-02-02 for certain CFM International, S.A. CFM56-3, CFM56-3B, and CFM56-3C turbofan engines. AD 2013-02-02 required removal from service of certain high-pressure turbine (HPT) disks manufactured by Global Material Solutions of Pratt & Whitney, at reduced maximum life limits. This AD corrects the serial numbers (S/Ns) listed in AD 2013-02-02. This AD was prompted by reports that certain HPT disk S/Ns in AD 2013- 02-02 and in certain Pratt & Whitney service information are incorrect. We are issuing this AD to prevent uncontained release of multiple turbine blades, damage to the engine, and damage to the airplane.

These special conditions are issued for the Bombardier Model DHC-8-100/-200/-300 series airplanes. These airplanes, as modified by Avmax Aviation Services Inc. (Avmax), will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport-category airplanes. This design feature is rechargeable lithium batteries to replace the existing nickel-cadmium and lead-acid rechargeable batteries. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for these design features. These 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.
Extension of the Requirement for Helicopters to Use the New York North Shore Helicopter Route
This rulemaking amends the expiration date of the final rule requiring pilots operating civil helicopters under Visual Flight Rules to use the New York North Shore Helicopter Route when operating along that area of Long Island, New York. The current rule expires on August 6, 2016. The FAA finds it necessary to extend the rule for an additional four years to preserve the current operating environment while the FAA conducts ongoing helicopter research that will be considered to determine appropriate future actions.
Extension of the Prohibition Against Certain Flights in the Simferopol (UKFV) and Dnipropetrovsk (UKDV) Flight Information Regions (FIRs); Technical Amendment
On October 27, 2015, the Federal Aviation Administration (FAA) published a final rule extending the prohibition against certain flight operations in the Simferopol (UKFV) and Dnipropetrovsk (UKDV) flight information regions (FIRs) by all United States (U.S.) air carriers; U.S. commercial operators; persons exercising the privileges of a U.S. airman certificate, except when such persons are operating a U.S.- registered aircraft for a foreign air carrier; and operators of U.S.- registered civil aircraft, except when such operators are foreign air carriers. The State Aviation Administration of Ukraine conducted and completed an airspace restructuring that altered the Simferopol (UKFV) and Dnipropetrovsk (UKDV) Flight Information Region (FIR) altitude structure specified in the final rule. To address the Ukraine airspace restructuring and provide additional clarity, this technical amendment specifically identifies the prohibited airspace in which Special Federal Aviation Regulation (SFAR) 113, applies, with inclusive altitudes and lateral limitations (latitude and longitude coordinates).
Proposed Establishment of Class E Airspace; Murray, KY
This action proposes to establish Class E airspace at Murray, KY, to accommodate new Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedures (SIAPs) serving Murray Calloway County Hospital Heliport. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations at the heliport.
Proposed Establishment of Class E Airspace; Camden, AL
This action proposes to establish Class E airspace at Camden, AL, to accommodate new Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedures (SIAPs) serving Camden Municipal Airport. Controlled airspace is necessary for the safety and management of instrument flight rules (IFR) operations at the airport.
Airworthiness Directives; M7 Aerospace LLC Airplanes
We are adopting a new airworthiness directive (AD) for all M7 Aerospace LLC Models SA26-AT, SA26-T, SA226-AT, SA226-T, SA226-T(B), SA226-TC, SA227-AC (C-26A), SA227-AT, SA227-BC (C-26A), SA227-CC, SA227-DC (C-26B), and SA227-TT airplanes. This AD was prompted by reports of multiple cracks in the steel horizontal tube of the cockpit control column. This AD requires inspection of the cockpit control column horizontal tube for cracks and repair or replacement of the cockpit control column as necessary. We are issuing this AD to correct the unsafe condition on these products.
Airworthiness Directives; Airbus Airplanes
We are adopting a new airworthiness directive (AD) for all Airbus Model A300 series airplanes; Model A300 B4-600, B4-600R, F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes); and Model A310 series airplanes. This AD was prompted by reports of partial loss of no-back brake (NBB) efficiency on the trimmable horizontal stabilizer actuator (THSA). This AD requires an inspection to determine THSA part numbers, serial numbers, and flight cycles on certain THSAs; and repetitive replacement of certain THSAs. We are issuing this AD to prevent loss of THSA NBB efficiency, which, in conjunction with the inability of the power gear to keep the ball screw in its last commanded position, could lead to an uncommanded movement of the horizontal stabilizer, possibly resulting in loss of control of the airplane.
Fourth Meeting Special Committee 235, Non-Rechargeable Lithium Battery and Batteries
The FAA is issuing this notice to advise the public of a meeting of Fourth Meeting Special Committee 235, Non-Rechargeable Lithium Battery and Batteries.
Agency Information Collection Activities: Requests for Comments; Clearance of Renewed Approval of Information Collection: Operations Specifications, Part 129 Application
In accordance with the Paperwork Reduction Act of 1995, FAA invites public comments about our intention to request the Office of Management and Budget (OMB) approval to renew an information collection. The FAA assesses the information collected and issues operations specifications to foreign air carriers. These operations specifications assure the foreign air carrier's ability to navigate and communicate safely within the U.S. National Airspace System.
Establishment of Class D Airspace: Destin, FL; Duke Field, Eglin AFB, FL; Revocation of Class D Airspace; Eglin AF Aux No 3 Duke Field, FL; and Amendment of Class D and E Airspace; Eglin Air Force Base, FL; Eglin Hurlburt Field, FL; and Crestview, FL
This action changes the effective date of a final rule published June 21, 2016, establishing Class D airspace at Destin, FL, providing the controlled airspace required for the Air Traffic Control Tower at Destin Executive Airport, (formerly Destin-Fort Walton Beach Airport). This allows for the disposition of comments received but not acknowledged prior to publishing the final rule. This action addresses a comment received, but not previously acknowledged.
Airworthiness Directives; International Aero Engines AG Turbofan Engines
We propose to adopt a new airworthiness directive (AD) for certain International Aero Engines AG (IAE) V2522-A5, V2524-A5, V2527- A5, V2527E-A5, V2527M-A5, V2530-A5, V2533-A5, V2525-D5, V2528-D5, and V2531-E5 turbofan engines. This proposed AD was prompted by nine in- flight shutdowns that resulted from premature failure of the No. 3 bearing. This proposed AD would require initial and repetitive inspections of the master magnetic chip detector (MMCD) and, if metallic debris is found, further actions depending on the type of metallic debris. This proposed AD would also require removal of the No. 3 bearing from service at the next engine shop visit. We are proposing this AD to prevent failure of the No. 3 bearing, failure of one or more engines, loss of thrust control, and loss of the airplane.
Changes to the Application Requirements for Authorization To Operate in Reduced Vertical Separation Minimum Airspace
This action revises the FAA's requirements for an application to operate in Reduced Vertical Separation Minimum (RVSM) airspace and eliminates the burden and expense of developing, processing, and approving RVSM maintenance programs. As a result of this revision, an applicant to operate in RVSM airspace will no longer be required to develop and submit an RVSM maintenance program solely for the purpose of obtaining an RVSM authorization. Because of other, independent FAA airworthiness regulations, all aircraft operators remain required to maintain RVSM equipment in an airworthy condition.
Changing the Collective Risk Limits for Launches and Reentries and Clarifying the Risk Limit Used To Establish Hazard Areas for Ships and Aircraft
The FAA is amending its regulations concerning the collective risk limits for commercial launches and reentries. These changes include: Separating the risk limits for commercial launches and reentries; aggregating the risk posed by impacting inert and explosive debris, toxic release, and far field blast overpressure; limiting the aggregate risk for these three hazards to 1 x 10-4; reducing the number of significant digits used in launch and reentry risk analysis; and various non-substantive clarifying revisions. These changes update FAA regulations to reflect the United States Government's greater experience with commercial launch and reentry and to align more closely the FAA's risk standards with those of other United States Federal agencies, while continuing to protect public safety.
Airworthiness Directives; The Boeing Company Airplanes
We propose to supersede Airworthiness Directive (AD) 2011-26- 03, which applies to certain The Boeing Company Model 777-200, -200LR, -300, and -300ER series airplanes. AD 2011-26-03 currently requires installing Teflon sleeving under the clamps of certain wire bundles routed along the fuel tank boundary structure, and cap sealing certain penetrating fasteners of the main and center fuel tanks. AD 2011-26-03 resulted from fuel system reviews conducted by the manufacturer. Since we issued AD 2011-26-03, we have received a report indicating that additional airplanes are affected by the identified unsafe condition. This proposed AD would add airplanes to the applicability. This AD would also add, for certain airplanes, detailed inspections of certain wire bundle clamps, certain Teflon sleeves, and certain fasteners; corrective actions if necessary; and installation of Teflon sleeves under certain wire bundle clamps. We are proposing this AD to prevent electrical arcing on the fuel tank boundary structure or inside the fuel tanks, which could result in a fire or explosion.

Proposed Establishment of Temporary Restricted Areas R-2509E, R-2509W, and R-2509N; Twentynine Palms, CA; Withdrawal
This action withdraws the NPRM published in the Federal Register of March 30, 2016, proposing to establish temporary restricted areas R-2509E, R-2509W, and R-2509N, Twentynine Palms, CA. The FAA has determined that withdrawal of that NPRM is warranted due to aeronautical impacts associated with the proposed action.
Notice of Proposed Rulemaking
This action proposes to modify the Class E airspace extending upward from 700 feet above the surface at Sonoma County Airport, Napa, CA, by removing an irregular shaped area located approximately 20 miles southwest of Napa County Airport. This airspace area is discontinuous from the airspace surrounding Napa County Airport and is not essential to instrument flight rules (IFR) operation at the airport. This proposal would also update the airport geographic coordinates. This action is necessary for the safety and management of instrument flight rules (IFR) operations at the airport, with the minimum amount of airspace restriction.
Public Notice for Waiver of Aeronautical Land-Use Assurance
The FAA is considering a proposal to change 0.059 acres of airport land from aeronautical use to non-aeronautical use and to authorize the disposal of airport property located at General Mitchell International Airport, Milwaukee, Wisconsin. The aforementioned land is no longer needed for aeronautical use. The property is located on the east side of Howell Avenue immediately south of Layton Avenue. The property is a 12 foot wide portion of airport property which has long been used as roadway setback, and is no longer needed for aeronautical purposes. Upon release, the land will be disposed of for sidewalk/roadway Right-of- Way.

Special Conditions: Cirrus Design Corporation, Model SF50; Whole Airplane Parachute Recovery System
These special conditions are issued for the Cirrus Design Corporation (Cirrus), model SF50 airplane. This airplane will have a novel or unusual design feature(s) associated with a whole airplane parachute recovery system. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These 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.
Airworthiness Directives; Sikorsky Aircraft Corporation Helicopters
We propose to adopt a new airworthiness directive (AD) for Sikorsky Aircraft Corporation (Sikorsky) Model S-92A helicopters. This proposed AD would require inspecting the main transmission forward (fwd) and aft frame assembly and adjacent skins for a crack and loose fasteners and establishing life limits for certain frame assemblies. This proposed AD is prompted by fatigue analysis indicating stress concentrations as well as the discovery of a crack in the station (STA) 362 frame and skin on a Model S-92A helicopter. The proposed actions are intended to detect a crack in a frame assembly and prevent failure of a frame and subsequent loss of control of the helicopter.
Airworthiness Directives; Bombardier, Inc. Airplanes
We propose to supersede Airworthiness Directive (AD) 2013-02- 08, for all Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. AD 2013-02-08 currently requires inspecting the trunnions and upper and lower pins of the horizontal stabilizer trim actuator (HSTA), and replacement or re-identification if necessary; and revising the maintenance program to include safe life limits and inspection requirements for the HSTA. Since we issued AD 2013-02-08, we determined that not all affected attachment pins and trunnions were included in the required inspections. In addition, for certain airplanes on which the replacement in AD 2013-02-08 was done, incorrect attachment hardware may have been used. This proposed AD would require measuring the diameter of certain bolts and attach holes, and, as applicable, measuring the diameter of the attach holes in the trunnions and pins, doing detailed visual inspections of the trunnions, pins, and spacers, doing corrective actions, and re-identifying trunnions and pins. This proposed AD also requires revising the maintenance or inspection program. This proposed AD also removes certain airplanes from the applicability. We are proposing this AD to prevent failure of the attachment pins and trunnions of the HSTA. This condition could result in separation of the horizontal stabilizer, and consequent loss of control of the airplane.
Airworthiness Directives; Bombardier, Inc. Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-400 series airplanes. This proposed AD was prompted by a determination by the manufacturer that shims might not have been installed between certain longerons and longeron joint fittings. This proposed AD would require repetitive inspections of the external surface of the fuselage skin panel for loose or working fasteners, and corrective action if necessary; a detailed visual inspection of the longeron joint fittings for the existence of shims and, if necessary, repetitive inspections of the longeron and the longeron joint fittings for any cracking, and corrective action if necessary. This proposed AD would also provide terminating action for certain repetitive inspections. We are proposing this AD to detect and correct missing shims between the longerons and longeron joint fittings. Such missing shims could result in a gapping condition and lead to stress corrosion cracking of the longeron joint fittings, and could adversely affect the structural integrity of the wing-to-fuselage attachment joints.
Airworthiness Directives; Bombardier, Inc. Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model BD-700-1A10 and BD-700-1A11 airplanes. This proposed AD was prompted by a determination that the existing instruction in a certain task in the aircraft maintenance manual (AMM) will not accomplish the intent of a certification maintenance requirement (CMR). This CMR task tests the pitch feel (PF) and rudder travel limiter actuator (RTLA) back-up modules in the flight control unit (FCU) to detect dormant failures. This proposed AD would require doing an operational test of the FCU back-up modules, and repair if necessary. We are proposing this AD to detect and correct a dormant failure of both FCU back-up modules. This condition, in combination with other failures in the FCU, may result in the inability to maintain the minimum control requirements for the PF and RTLA, which could create hazardous flight control inputs during flight.
Airworthiness Directives; Rolls-Royce plc Turbofan Engines
We propose to adopt a new airworthiness directive (AD) for all Rolls-Royce plc (RR) RB211-Trent 875-17, RB211-Trent 877-17, RB211- Trent 884-17, RB211-Trent 884B-17, RB211-Trent 892-17, RB211-Trent 892B-17, and RB211-Trent 895-17 turbofan engines. This proposed AD was prompted by a report of cracking and material release from an engine upper bifurcation fairing. This proposed AD would require repetitive inspections of the engine upper bifurcation fairing and repairing or replacing any fairing that fails inspection. We are proposing this AD to prevent failure of the engine fire protection system, engine fire, and damage to the airplane.
Special Conditions: Gulfstream Aerospace Corporation Model GVII-G500 Airplanes; Isolation or Protection of Airplane Electrical-System Security From Unauthorized Internal Access
These special conditions are issued for the Gulfstream Aerospace Corporation (Gulfstream) Model GVII-G500 airplane. This airplane will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport-category airplanes. This design feature is a digital systems architecture requiring isolation or protection from unauthorized internal access. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These 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.
Special Conditions: American Airlines, Boeing 777-200 Series Airplanes; Dynamic Test Requirements for Single-Occupant Oblique (Side-Facing) Seats Equipped With Inflatable Lapbelts
These special conditions are issued for the Boeing 777-200 series airplane. This airplane, as modified by American Airlines, will have novel or unusual design features when compared to the state of technology envisioned in the airworthiness standards for transport- category airplanes. These airplanes will include single-occupant oblique seats with inflatable lapbelts requiring dynamic testing. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for these design features. These 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.
Safety Management System for Certificated Airports
On October 7, 2010, the FAA published in the Federal Register a notice of proposed rulemaking (NPRM) to require certificate holders to establish a safety management system (SMS) for the entire airfield environment, including movement and non-movement areas, to improve safety at airports hosting air carrier operations. After reviewing the comments received and conducting further internal analysis, the FAA is amending that proposal. The FAA now proposes to require an SMS only for a certificated airport classified as a small, medium, or large hub airport in the National Plan of Integrated Airport Systems; serving international air traffic; or having more than 100,000 total annual operations. The FAA is also proposing changes that would extend the implementation period from 18 to 24 months; require submission of an implementation plan within 12 months instead of 6 months of the effective date of the final rule; modify the training requirements; ensure consistency among various FAA SMS initiatives, and reduce the implementation burden.
Amendment of Class E Airspace for the Following Louisiana Towns; De Quincy, LA; Minden, LA; Slidell, LA; and Revocation of Class E Airspace; Homer, LA
This action modifies Class E airspace extending upward from 700 feet above the surface at De Quincy Industrial Airpark, De Quincy, LA; Minden Airport, Minden, LA; and Slidell, Airport, Slidell, LA. The decommissioning of non-directional radio beacons (NDB) and/or cancellation of NDB approaches due to advances in Global Positioning System (GPS) capabilities, and implementation of area navigation (RNAV) procedures have made this action necessary for the safety and management of Instrument Flight Rules (IFR) operations at these airports. This action also removes Class E airspace extending upward from 700 feet above the surface at Homer Municipal Airport, Homer, LA, as controlled airspace is no longer needed. Additionally, the name of Minden Airport (formerly Minden-Webster Airport) and the geographic coordinates at De Quincy Industrial Airpark, Minden Airport, and Slidell Airport are being adjusted to coincide with the FAA's aeronautical database.

Airworthiness Directives; The Boeing Company
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 787-8 and 787-9 airplanes. This proposed AD was prompted by a report that some inboard and outboard trailing edge flap rotary actuators may have been assembled with an incorrect no-back brake rotor-stator stack sequence during manufacturing. This proposed AD would require an inspection of the inboard and outboard flap trailing edge rotary actuator for any discrepant rotary actuator. For discrepant rotary actuators, this proposed AD would require replacing the rotary actuator, or determining the flight cycles on the rotary actuator and doing related investigative and corrective actions if necessary. We are proposing this AD to detect and replace rotary actuators having incorrect assembly, which could cause accelerated unit wear that will eventually reduce braking performance. This degradation could lead to loss of no- back brake function and reduced controllability of the airplane.
Airworthiness Directives; The Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737-100, -200, and -200C series airplanes. This proposed AD is intended to complete certain mandated programs intended to support the airplane reaching its limit of validity (LOV) of the engineering data that support the established structural maintenance program. This proposed AD would require repetitive detailed, high frequency eddy current (HFEC), and ultrasonic inspections of the center section rear spar upper clevis lugs and horizontal stabilizer rear spar upper lugs, as applicable, for any cracking, and related investigative and corrective actions if necessary. For certain airplanes, this proposed AD would require replacement of the center section rear spar upper chord with a new part and a serviceable center section assembly. This proposed AD would also require repetitive HFEC and fluorescent dye penetrant inspections of the center section for cracking of the front and rear spar upper clevis lugs or horizontal stabilizer front and rear spar upper lugs, and related investigative and corrective actions if necessary. We are proposing this AD to detect and correct cracking in the rear spar upper clevis lugs of the center section, and in the rear spar upper lugs of the horizontal stabilizer which could result in the loss of structural integrity and controllability of the airplane.
Airworthiness Directives; Bombardier, Inc. Airplanes
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440), Model CL-600-2C10 (Regional Jet Series 700, 701, & 702), Model CL-600- 2D15 (Regional Jet Series 705), Model CL-600-2D24 (Regional Jet Series 900), and Model CL-600-2E25 (Regional Jet Series 1000) airplanes. This AD was prompted by reports of undesirable changes in the Reference Airspeed (RAS) Bug, occurring during flight without pilot input. This AD requires replacing the flight control computer (FCC). We are issuing this AD to prevent uncommanded pitch changes, which could result in deviation from a safe flight path.
Airworthiness Directives; Airbus Airplanes
We are superseding Airworthiness Directive (AD) 2015-10-03 for certain Airbus Model A330-200 and -300 series airplanes, and Model A340-200 and -300 series airplanes. AD 2015-10-03 required a detailed inspection for visible chrome of each affected main landing gear (MLG) sidestay upper cardan pin, associated nuts, and retainer assembly; pin replacement if needed; measurement of cardan pin clearance dimensions (gap check); corrective actions if necessary; and a report of all findings. This new AD requires a detailed inspection of the upper cardan pin and nut threads for any corrosion, pitting, or thread damage, and if necessary, replacement of the cardan pin and nut. This new AD also revises the applicability to include additional airplane models. This AD was prompted by a report that an MLG sidestay upper cardan pin migration event had been caused by corrosion due to lack of jointing compound and inadequate sealant application during the MLG installation. We are issuing this AD to detect and correct migration of the sidestay upper cardan pin, which could result in disconnection of the sidestay upper arm from the airplane structure, and could result in a landing gear collapse and consequent damage to the airplane and injury to occupants.
Airworthiness Directives; Airbus Airplanes
We are superseding Airworthiness Directive (AD) 2014-14-06 for all Airbus Model A318-111 and -112 airplanes; Model A319-111, -112, - 113, -114, and -115 airplanes; Model A320-111, -211, -212, and -214 airplanes; and Model A321-111, -112, -211, -212, and -213 airplanes. AD 2014-14-06 required inspecting the aft engine mount retainers for surface finish, cracks, and failure, and replacement if necessary. This new AD requires repetitive inspections for damaged, cracked, broken, and missing aft engine mount retainers, and replacement if necessary. This AD was prompted by inspection results that have shown that the main cause of crack initiation in the aft engine mount retainers is the vibration dynamic effect that affects both retainers, either with ``dull'' or ``bright'' surface finishes. We are issuing this AD to detect and correct failure of retainer brackets of the aft engine mount and consequent loss of the locking feature of the nuts of the inner and outer pins; loss of the pins will result in the aft mount engine link no longer being secured to the aft engine mount.
Airworthiness Directives; Dassault Aviation Airplanes
We are adopting a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 7X airplanes. This AD was prompted by a report of improperly drilled bores, located on upper and lower stiffener joints to the Web at a certain frame. This AD requires a one- time inspection of the bores, and repair if necessary. We are issuing this AD to detect and correct an unsatisfactory bore that can adversely affect the structural integrity of the airplane.
Airworthiness Directives; Airbus Airplanes
We are adopting a new airworthiness directive (AD) for certain Airbus Model A330-200 Freighter series airplanes; Model A330-200 and A330-300 series airplanes; Model A340-200 and A340-300 series airplanes; Model A340-500 series airplanes; and Model A340-600 series airplanes. This AD was prompted by a report indicating that, during an operational test of a ram air turbine (RAT), the RAT did not deploy in automatic mode. This AD requires identification of the manufacturer, part number, and serial number of the RAT, and re-identification and modification of the RAT if necessary. We are issuing this AD to prevent non-deployment of the RAT, which, if preceded by a total engine flame- out, or during a total loss of normal electrical power generation, could result in reduced control of the airplane.
Airworthiness Directives; Saab AB, Saab Aeronautics (Formerly Known as Saab AB, Saab Aerosystems) Airplanes
We are revising an earlier proposed airworthiness directive (AD) for certain Saab AB, Saab Aeronautics Model 340A (SAAB/SF340A) and SAAB 340B airplanes. The NPRM proposed to supersede AD 2012-24-06. AD 2012-24-06 currently requires replacing the stall warning computer (SWC) with a new SWC that provides an artificial stall warning in icing conditions, and modifying the airplane for the replacement of the SWC. The NPRM was prompted by a determination that airplanes with certain modifications were excluded from the applicability in AD 2012-24-06, and are affected by the identified unsafe condition; and the SWC required by AD 2012-24-06 contained erroneous logic. This action revises the NPRM by reducing the compliance time for replacing the SWCs. We are proposing this supplemental NPRM (SNPRM) to prevent natural stall events during operation in icing conditions, which could result in loss of control of the airplane. Since this compliance time reduction imposes an additional burden to operators, we are reopening the comment period to allow the public the chance to comment on these proposed changes.
Airworthiness Directives; Bombardier, Inc. Airplanes
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2B16 (CL-604 Variant) airplanes. This AD was prompted by a determination that certain maintenance tasks for the horizontal stabilizer trim actuator (HSTA) are inadequate. This AD requires revising the maintenance or inspection program, as applicable, to incorporate new airworthiness limitations for the HSTA. We are issuing this AD to detect and correct premature wear and cracking of the HSTA, which could result in failure of the HSTA and consequent loss of control of the airplane.
