Federal Aviation Administration March 2014 – Federal Register Recent Federal Regulation Documents

This action proposes to establish Class E airspace at Conway, AR. Controlled airspace is necessary to accommodate new Standard Instrument Approach Procedures (SIAPs) at Cantrell Field. The FAA is taking this action to enhance the safety and management of Instrument Flight Rules (IFR) operations for SIAPs at the airport.

We propose to adopt a new airworthiness directive (AD) for certain DASSAULT AVIATION Model FALCON 900EX airplanes. This proposed AD was prompted by our determination of the need for a revision to the airplane airworthiness limitations to introduce a corrosion prevention control program, among other changes, to the maintenance requirements and airworthiness limitations. This proposed AD would require revising the maintenance or inspection program, as applicable, to include the maintenance tasks and airworthiness limitations specified in the Airworthiness Limitations section of the airplane maintenance manual. We are proposing this AD to prevent reduced structural integrity of the airplane, and prevent reduced controllability of the airplane.

We are adopting a new airworthiness directive (AD) for all Pratt & Whitney (PW) PW2037, PW2037D, PW2037M, PW2040, PW2040D, PW2043, PW2146, PW2240, PW2337, PW2643, and F117-PW-100 turbofan engines. This AD was prompted by a rupture of the diffuser-to-high-pressure turbine (HPT) case flange. This AD requires a one-time eddy current inspection (ECI) of affected engines with certain diffuser and HPT cases installed. This AD also requires a fluorescent-penetrant inspection (FPI) of the diffuser case rear flange and HPT case front flange. We are issuing this AD to prevent failure of the diffuser-to-HPT case flange, which could lead to uncontained engine failure and damage to the airplane.

We propose to adopt a new airworthiness directive (AD) for certain Embraer S.A. Model ERJ 170 airplanes. This proposed AD was prompted by reports of ``BLEED 1(2) LEAK'' messages displayed on the Engine Indication and Crew Alert System (EICAS), and indirect damage to components of the Electrical Wiring Interconnection System (EWIS) in the engine pylon area. This proposed AD would require inspecting the EWIS components for damage, and repair if necessary. This proposed AD would also require installing pre-cooler deflectors on the left- and right-hand pylons, and applying silicone sealant. We are proposing this AD to prevent indirect damage to EWIS components near the engine bleed air pre-coolers, which could result in a dual engine roll back to idle and consequent dual engine power loss and reduced controllability of the airplane.

We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 787-8 airplanes. This proposed AD was prompted by a report indicating that, on a different Boeing airplane model, there was an oxygen-fed fire, which caused extensive damage to the flight deck. This proposed AD would require replacing the low- pressure oxygen hoses with non-conductive hoses in the crew oxygen system. We are proposing this AD to prevent inadvertent electrical current from passing through an internal, anti-collapse spring of the low pressure oxygen hose, which can cause the low-pressure oxygen hose to melt or burn, leading to an oxygen-fed fire and/or smoke beneath the flight compartment in the forward electronics equipment bay.

We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 727 airplanes. This AD will 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 AD requires repetitive inspections for cracking of small repairs done on the vertical flange of the rib chord, repetitive inspections for cracking along the upper fillet radius of the rib chord, and a large repair or preventive modification if necessary. Accomplishment of a large repair or preventive modification terminates the actions of this AD. We are issuing this AD to prevent cracks in the rib upper chord, which could result in the inability of the wing structure to support the limit load condition, and consequent loss of structural integrity of the wing.

We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8 airplanes. This AD requires repetitive functional checks of the nose and main landing gear, and corrective actions if necessary. This AD also provides optional terminating action for the repetitive functional checks. This AD was prompted by a report that the emergency downlock indication system (EDIS) had given a false landing gear down-and-locked indication. We are issuing this AD to detect and correct a false down-and-locked landing gear indication, which, on landing, could result in possible collapse of the landing gear.

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 fuel system reviews conducted by the manufacturer. This proposed AD would require replacing a fitting that is part of the refuel control solenoid valve assembly. We are proposing this AD to prevent the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.

We are adopting a new airworthiness directive (AD) for British Aerospace Regional Aircraft Jetstream Series 3101 and Jetstream Model 3201 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 stress corrosion cracking of the main landing gear yoke pintle housing on a Jetstream series 3100 airplane. We are issuing this AD to require actions to address the unsafe condition on these products.

We are superseding Airworthiness Directive (AD) 2008-08-25 that applied to certain The Boeing Company Model 747-400 and 747-400F series airplanes. AD 2008-08-25 required installing drains and drain tubes to eliminate water accumulation in the drip shield above the M826 cardfile in the main equipment center. This new AD requires installing modified drain tubes, relocating wire bundle routing, installing a new drip shield and drip shield deflectors, and replacing insulation blankets. For certain airplanes, this new AD also concurrently requires sealing the drain slot, installing spuds, and installing drain tubes. This AD was prompted by reports of continued water damage to diode fire card 285U0072-1 in the M826 automatic fire overheat logic test system cardfile following a false FWD CARGO FIRE message, with no change in frequency, which resulted in an air turn back. We are issuing this AD to prevent water from exiting over the edge of the existing drip shield and contaminating electrical components in the M826 cardfile, which could result in an electrical short and potential loss of several functions essential for safe flight.

We are superseding Airworthiness Directive (AD) 2008-08-04 for certain Airbus Model A318, A319, A320, and A321 series airplanes. AD 2008-08-04 required repetitive inspections for cracking in the forward lug of the support rib 5 fitting of the left and right main landing gear (MLG), and repair or replacement of any cracked MLG fitting if necessary. AD 2008-08-04 also required modification of the rib bushings of the left and right MLG, which ended the repetitive inspections. This new AD requires, for airplanes on which certain modifications or repairs have been done, repetitive inspections for cracks of the forward lug of each left-hand and right-hand MLG support rib 5 fitting, and repair if necessary; and adds Model A318 series airplanes to the applicability. Replacement of an MLG support rib 5 fitting terminates the repetitive inspection requirements for the MLG support rib 5 fitting at that position. This AD was prompted by reports of cracks found in the forward lug of the MLG support rib 5 fitting. We are issuing this AD to prevent cracking in the forward lug of the MLG, which could result in failure of the lug and consequent collapse of the MLG during takeoff or landing.

We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 727 airplanes. This AD was prompted by certain mandated programs intended to support the airplane reaching its limit of validity of the engineering data that support the established structural maintenance program. This AD requires an inspection for cracks in the main wheel well pressure floor and a preventive modification or permanent repair, as applicable. We are issuing this AD to prevent cracking in the main wheel well pressure floor, which could result in reduced structural integrity of the airplane, and decompression of the cabin.

This action amends the Order Limiting Operations at Newark Liberty International Airport (EWR) that published on May 21, 2008, and was amended on October 7, 2009, April 4, 2011, and May 14, 2013. The Order remains effective until the final Rule on Slot Management and Transparency for LaGuardia Airport, John F. Kennedy International Airport, and Newark Liberty International Airport becomes effective but not later than October 29, 2016.

We propose to supersede Airworthiness Directive (AD) 2005-13- 05, which applies to certain Boeing Model 747-400F series airplanes. AD 2005-13-05 currently requires inspections for cracking of the web, upper chord, and upper chord strap of the upper deck floor beams, and repair of any cracking. AD 2005-13-05 also requires a preventive modification of the upper deck floor beams, and repetitive inspections for cracking after accomplishing the modification. Since we issued AD 2005-13-05, the upper chords of the upper deck floor beams at certain stations have been determined to be structures that are susceptible to widespread fatigue damage, and certain airplanes with an initial modification require a second modification for the airplane to meet its limit of validity (LOV). This proposed AD would require that second modification and repetitive inspections for cracking and repair if necessary. We are proposing this AD to detect and correct fatigue cracking in certain upper chords of the upper deck floor beam, which could result in reduced structural integrity of the airplane and rapid decompression or reduced controllability of the airplane.

We propose to adopt a new airworthiness directive (AD) for all Dassault Aviation Model FALCON 7X airplanes. This proposed AD was prompted by reports that the pintle pins installed on a certain number of airplanes may be incorrectly protected against corrosion. This proposed AD would require replacing certain pintle pins on the left- and right-hand main landing gear (MLG) with a serviceable part. We are proposing this AD to detect and correct pintle pins that have been incorrectly corrosion-protected, which could cause the pintle pins to shear under normal load and lead to the collapse of the MLG during take-off or landing.

This rule establishes, amends, suspends, or revokes Standard Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.

In accordance with the National Environmental Policy Act of 1969, as amended (NEPA; 42 U.S.C. 4321, et seq.), Council on Environmental Quality NEPA implementing regulations (40 CFR Parts 1500- 1508), and FAA Order 1050.1E, Environmental Impacts: Policies and Procedures, Change 1, the FAA is announcing the availability of and requesting comments on the Draft EA for the Midland International Air and Space Port, City of Midland, Midland County, Texas.

The FAA is issuing this notice to advise the public of twenty- first meeting of RTCA Special Committee 214 to be held jointly with EUROCAE WG-78: Standards for Air Traffic Data Communication Services.

We are superseding airworthiness directive (AD) 2009-16-03 for certain Continental Motors, Inc. (CMI) IO-520, TSIO-520, and IO-550 series reciprocating engines, with certain SAP replacement parts manufacturer approval (PMA) investment cast cylinder assemblies installed. AD 2009-16-03 required initial and repetitive inspections and compression tests to detect cracks in those cylinders. This new AD requires that additional engines be added to the applicability. This AD was prompted by the need to add to the applicability all other engine models approved for the use of CMI 520 and 550 cylinder assemblies, such as the CMI 470 series engines when modified by supplemental type certificate (STC), with affected SAP investment cast cylinder assemblies installed. We are issuing this AD to prevent the separation of the cylinder head, damage to the engine, and damage to the airplane.

We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 747-200B, 747-200F, 747-300, 747SP, 747-400, and 747-400F series airplanes equipped with Rolls-Royce RB211-524 engines; and certain Model 767-300 series airplanes equipped with Rolls-Royce RB211-524 engines. This AD was prompted by multiple reports of uncommanded thrust reverser unlock events. This AD requires replacing certain relays and relay sockets, and doing wiring changes. For certain airplanes, this AD also requires installing new relay panels, and removing and installing certain components. Additionally, this AD requires, for certain airplanes, accomplishing concurrent actions, which include installing an additional locking system on the thrust reversers and modifying system wiring for in-flight fault indications of the thrust reverser system. We are issuing this AD to prevent an uncommanded thrust reverser deployment during takeoff or in flight, resulting in decreased airplane control and performance, possible runway excursions, and failure to climb.

We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 747-400 series airplanes. This AD was prompted by reports of auxiliary power unit (APU) faults due to power feeder cable chafing. This AD requires detailed inspections for damage of the APU power feeder cables; replacing the clamps and installing grommets; and related investigative and corrective actions if necessary. We are issuing this AD to detect and correct chafing of the APU power feeder cables within a flammable fluid leakage zone, which, with arcing, could result in fire and structural damage.

This action makes an editorial change to the legal description of VHF Omnidirectional Range (VOR) Federal airway V-626 to reverse the order of points listed in the route description. This action is simply to comply with the standard format for describing routes. The existing alignment of the airway is not affected by this action.

We are adopting a new airworthiness directive (AD) for all M7 Aerospace LLC Models 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), SA227- TT, SA26-AT, and SA26-T airplanes. This AD was prompted by reports of airplanes with multiple fatigue cracks in the FS 69.31 front pressure bulkhead. This AD requires repetitively inspecting (visually) the FS 51.31 front pressure bulkhead on SA26 series airplanes and FS 69.31 front pressure bulkhead on SA226 and SA227 series airplanes for cracks, and repairing any cracked bulkhead; this AD also requires reporting certain inspection results to M7 Aerospace LLC. We are issuing this AD to correct the unsafe condition on these products.

We are adopting a new airworthiness directive (AD) for all Rolls-Royce plc (RR) RB211-Trent 970-84, RB211-Trent 970B-84, RB211- Trent 972-84, RB211-Trent 972B-84, RB211-Trent 977-84, RB211-Trent 977B-84, and RB211-Trent 980-84 turbofan engines. This AD requires inspections of the low-pressure turbine exhaust case and support assembly or tail bearing housing (TBH) to detect cracks or damage. This AD was prompted by an RR structural re-analysis indicating that the TBH may not retain full limit load capability in all fail-safe conditions. We are issuing this AD to prevent failure of the TBH, resulting in damage to the engine and damage to the airplane.
