Airworthiness Directives; Bombardier, Inc. Airplanes
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2E25 (Regional Jet Series 1000) airplanes. This AD was prompted by a determination that without an effective maintenance task to maintain the airplane's inherent level of safety, there is a potential that a dormant failure of the alternate release system of the landing gear could occur. This AD requires revising the maintenance or inspection program, as applicable, to incorporate a maintenance task for an operational check of the electro- mechanical actuator and release mechanism of the alternate extension system for the nose landing gear and main landing gear. We are issuing this AD to prevent failure of the alternate release system of the landing gear, which could prevent the landing gear from extending during a failure of the normal landing gear extension system.
Airworthiness Directives; Airbus Airplanes
We are adopting a new airworthiness directive (AD) for certain Airbus Model A318-111 and -112 airplanes and Model A319, A320, and A321 series airplanes. This AD was prompted by reports of cracks on the forward corner fittings of engine pylon aft secondary structures. This AD requires repetitive inspections of certain forward corner fittings of the pylon aft secondary structures, and corrective actions if necessary. This AD also provides optional terminating action for the repetitive inspections. We are issuing this AD to detect and correct detachment of the lower fairing attachment and/or loss of the aft fixed fairing with the movable fairing from the airplane in flight, which could result in damage to the airplane.
Airworthiness Directives; The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-600 and -700 series airplanes. This AD was prompted by reports of cracking in the body station (STA) 727 bulkhead lower frame. This AD requires a detailed and open hole high frequency eddy current (HFEC) inspection of the left- and right-side lower frame webs and inner chords for cracking, and corrective actions and preventative modifications if necessary. This AD also provides for optional terminating action of the repetitive inspections, under certain conditions. We are issuing this AD to detect and correct cracking in a bulkhead lower frame web and inner chord, which could result in a severed frame and induced skin cracks, and could lead to rapid decompression of the fuselage.
Airworthiness Directives; Bombardier, Inc. Airplanes
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-1A11 (CL-600), CL-600-2A12 (CL-601), and CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604 Variants) airplanes. This AD was prompted by a determination that the forward lugs of the flap hinge box might not conform to engineering drawings, which could result in premature fatigue cracking. This AD requires revising the maintenance or inspection program to include new airworthiness limitations tasks; and measuring the forward lug edge distance of each flap hinge box, inspecting for cracking and damage (i.e., deformation or bearing failure) of the forward lug edge of each flap hinge box, and repairing any cracking or damage if necessary. We are issuing this AD to detect and correct non-conforming flap hinge box forward lugs, which could result in failure of the lugs and detachment of the flap hinge box and consequent detachment of the flap surface.

Airworthiness Directives; Rolls-Royce plc Turbofan Engines
We propose to adopt a new airworthiness directive (AD) for all Rolls-Royce plc (RR) RB211-535E4-37, RB211-535E4-B-37, and RB211-535E4- C-37 turbofan engines. This proposed AD was prompted by RR updating the life limits for certain high-pressure turbine (HPT) disks. This proposed AD would require reducing the cyclic life limits for certain HPT disks, removing those disks that have exceeded the new life limit, and replacing them with serviceable parts. We are proposing this AD to prevent failure of the HPT disk, which could result in uncontained disk release, damage to the engine, and damage to the airplane.
Airworthiness Directives; Rolls-Royce plc Turbofan Engines
We propose to adopt a new airworthiness directive (AD) for certain Rolls-Royce plc (RR) RB211-524B-02, RB211-524B2-19, RB211- 524B3-02, RB211-524B4-02, RB211-524B4-D-02, RB211-524C2-19, RB211- 524D4-19, RB211-524D4-39, and RB211-524D4X-19 turbofan engines. This proposed AD was prompted by several failures of affected high-pressure turbine (HPT) blades. This proposed AD would require removing affected HPT blades. We are proposing this AD to prevent failure of the HPT blade, which could lead to failure of one or more engines, loss of thrust control, and damage to the airplane.
Airworthiness Directives; The Boeing Company Airplanes
We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 747-8 series airplanes. This proposed AD was prompted by a report of improperly installed outboard stowage bin modules in the passenger compartment found during maintenance. Further investigation revealed that certain attachment bracket bushings were missing or had moved out of the holes. This proposed AD would require installing a spacer on the end of each quick-release pin that attaches the outboard stowage bin module to the lateral support tie rods of the main deck passenger compartment. We are proposing this AD to prevent detachment of the quick-release pin, which could result in separation of the lateral support tie rod and subsequent detachment of the module and consequent injuries to passengers or flightcrew.
Airworthiness Directives; Various Aircraft Equipped With Wing Lift Struts
We are superseding Airworthiness Directive (AD) 99-01-05 R1, which applied to certain aircraft equipped with wing lift struts. AD 99-01-05 R1 required repetitively inspecting the wing lift struts for corrosion; repetitively inspecting the wing lift strut forks for cracks; replacing any corroded wing lift strut; replacing any cracked wing lift strut fork; and repetitively replacing the wing lift strut forks at a specified time for certain airplanes. This new AD retains all requirements of AD 99-01-05R1 and adds additional airplane models to the Applicability section. This AD was prompted by a report that additional Piper Aircraft, Inc. model airplanes should be added to the Applicability section. We are issuing this AD to correct the unsafe condition on these products.
Special Conditions: Boeing Model 787-9, Dynamic Test Requirements for Single-Occupant Oblique (Side-Facing) Seats With Airbag Devices
These special conditions are issued for the Boeing Model 787-9 airplane. This airplane has a novel or unusual design feature associated with side-facing, oblique seats. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for occupants of seats installed at an angle of greater than 18 degrees, but substantially less than 90 degrees, to the centerline of the airplane, nor for airbag devices. 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; Lycoming Engines Reciprocating Engines
The FAA is withdrawing a notice of proposed rulemaking (NPRM). The NPRM proposed a new airworthiness directive (AD) that had applied to certain Lycoming Engines (type certificate formerly held by Textron Lycoming) with Superior Air Parts, Inc. (SAP), piston pins installed. The NPRM had applied to those engines using SAP piston pins, part number (P/N) 13444-1. The proposed action would have required removal of defective SAP piston pins, P/N 13444-1, from service. Since we issued the NPRM, we have learned that all the affected piston pins have been removed from service. We also found that SAP has revised its manufacturing process so that the subsequent piston pins were no longer susceptible to cracking. Accordingly, we withdraw the proposed rule.
Airworthiness Directives; Airbus Airplanes
We are superseding Airworthiness Directive (AD) 2014-26-53 and AD 2015-03-02 for certain Airbus Model A319-115, A319-133, A320-214, A320-232, and A320-233 airplanes. AD 2014-26-53 required repetitive detailed visual inspections to detect discrepancies of the wing lower skin surface and inboard main landing gear (MLG) support rib lower flange location fasteners and, depending on findings, accomplishment of applicable corrective action(s). AD 2015-03-02 required repetitive detailed visual inspections of the outboard MLG support rib lower flange fasteners for discrepancies, and corrective actions if necessary. This new AD retains the repetitive detailed visual inspections to detect discrepancies of the fasteners located in the wing lower skin surface and inboard MLG support rib lower flange with extended compliance times and repetitive intervals, and accomplishment of applicable corrective actions. This new AD also retains the repetitive detailed visual inspections of the outboard MLG support rib lower flange fasteners for discrepancies, and corrective actions if necessary. In addition, this new AD adds airplanes to the applicability. This AD was prompted by a determination that certain airplanes were missing from the applicability of AD 2014-26-53 and AD 2015-03-02 and that those airplanes may be affected by the unsafe condition addressed in AD 2014-26-53 and AD 2015-03-02. We are issuing this AD to detect and correct discrepancies of the fasteners at the external surface of the lower wing skin and inboard and outboard MLG support rib lower flanges, which could result in an airplane not meeting its maximum loads expected in service. This condition could result in structural failure.
Airworthiness Directives; Airbus Airplanes
We are superseding Airworthiness Directive (AD) 2007-14-05 for all Airbus Model A310 and Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes). AD 2007-14-05 required revising the Airworthiness Limitations section of the Instructions for Continued Airworthiness by incorporating certain certification maintenance requirements. This new AD requires revising the maintenance or inspection program to incorporate more restrictive maintenance requirements and airworthiness limitations. This AD was prompted by a determination that more restrictive maintenance requirements and airworthiness limitations are necessary. We are issuing this AD to prevent safety-significant latent failures that would, in combination with one or more other specific failures or events, result in a hazardous or catastrophic failure condition of avionics, hydraulic systems, fire detection systems, fuel systems, or other critical systems.
Airworthiness Directives; Airbus Airplanes
We propose to supersede Airworthiness Directive (AD) 97-07-14, for certain Airbus Model A320-111, -211, and -231 airplanes. AD 97-07- 14 currently requires modification of an area on the front spar of the wing center section by installing shims and new fasteners to reinforce pressure floor fittings. Since we issued AD 97-07-14, we have determined the need for repetitive inspections on airplanes on which the modification of the rib flange on the front spar of the wing center section has been done. This proposed AD would continue to require modifying the rib flange on the front spar of the wing center section by installing shims and new fasteners to reinforce pressure floor fittings; and would require repetitive high frequency eddy current inspections for cracking of the radius of the rib flanges and vertical stiffener at frame 36, a rototest inspection for cracking of the fastener holes of the rib flanges, repair if needed, and adding additional airplanes to the applicability. We are proposing this AD to prevent fatigue cracking on the rib flange area of the front spar of the wing center section, which can reduce the structural integrity of fuselage frame 36 and the wing center section.

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 a report of a rupture of a main landing gear (MLG) sliding tube axle. This proposed AD would require an inspection to identify the part number and serial number of the MLG sliding tubes installed on the airplane; and an inspection of the axle on certain MLG sliding tubes for burned areas, and replacement of the sliding tube if necessary. We are proposing this AD to detect and correct cracks in the axle and (partial) detachment of the axle and wheel from the sliding tube, which could result in failure of an MLG.
Airworthiness Directives; Dassault Aviation Airplanes
We are superseding Airworthiness Directive (AD) 2013-26-05 for all Dassault Aviation Model FAN JET FALCON, FAN JET FALCON SERIES C, D, E, F, and G airplanes; Model MYSTERE-FALCON 200 airplanes; and Model MYSTERE-FALCON 20-C5, 20-D5, 20-E5, and 20-F5 airplanes. AD 2013-26-05 required repetitive weighing of fire extinguisher bottles having a certain part number, and eventual replacement of those bottles to terminate the repetitive weighing. This new AD continues to require repetitive weighing of fire extinguisher bottles having a certain part number, and eventual replacement of those bottles to terminate the repetitive weighing. This AD was prompted by our determination that certain text in the method of compliance language specified in AD 2013- 26-05 incorrectly refers to Airbus, instead of ``Dassault Aviation.'' We are issuing this AD to detect and correct a dormant failure in the fire suppression system, which could result in the inability to put out a fire in an engine, auxiliary power unit (APU), or rear compartment.
Grand Canyon National Park Quiet Aircraft Technology Incentive: Seasonal Relief From Allocations in the Dragon and Zuni Point Corridors
On November 10, 2014, the Federal Aviation Administration (FAA) and the National Park Service (NPS) published in the Federal Register [79 FR 66763-66765] a notice of the agencies' proposal to provide a quiet aircraft technology incentive for commercial air tour operators at Grand Canyon National Park and a request for public comments. Specifically, the agencies proposed to provide seasonal relief from allocations in the Dragon and Zuni Point corridors for commercial air tour operators that convert or have converted to quiet aircraft technology. The FAA and the NPS have reviewed and considered all comments, and have decided to proceed with implementation of the incentive as proposed. This notice describes that decision and responds to the substantive comments received.
Airworthiness Directives; Zodiac Aerotechnics (Formerly Intertechnique Aircraft Systems)
We propose to adopt a new airworthiness directive (AD) for certain Zodiac Aerotechnics (formerly Intertechnique Aircraft Systems) flightcrew oxygen mask regulators as installed on, but not limited to, various transport and small airplanes. This proposed AD was prompted by a report that improper maintenance on oxygen mask regulators was found. This proposed AD would require the identification and replacement of all potentially affected units. This proposed AD also would require installation of a placard and revision of the airplane flight manual to include an operational procedure for use in case of depressurization. We are proposing this AD to detect and correct affected oxygen mask regulators, which could lead to inadequate protection to the affected flightcrew against hypoxia. Hypoxia can start from a headache and drowsiness and lead eventually to unconsciousness with severe consequence in terms of airplane controllability.
Airworthiness Directives; Sikorsky Aircraft Corporation (Type Certificate Previously Held by Schweizer Aircraft Corporation)
We propose to adopt a new airworthiness directive (AD) for Sikorsky Aircraft Corporation (Sikorsky) Model 269A, 269A-1, 269B, 269C, 269C-1, 269D, and TH-55A helicopters. This proposed AD would require repetitively inspecting and lubricating the tail rotor (T/R) driveshaft splined fittings. This proposed AD is prompted by a report that the T/R driveshaft can disconnect due to deterioration of the splined coupling. The proposed actions are intended to detect and prevent excessive wear of the splined coupling, which could lead to failure of the T/R driveshaft and subsequent loss of control of the helicopter.
