Airworthiness Directives; PILATUS Aircraft Ltd. Airplanes
We propose to adopt a new airworthiness directive (AD) for PILATUS Aircraft Ltd. Model PC-7 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 the potential for a spring on the compressor clutch plate to shear the oil cooler inlet-hose due to the close routing of these parts without a protective cover. We are issuing this proposed AD to require actions to address the unsafe condition on these products.
Harmonization of Airworthiness Standards-Gust and Maneuver Load Requirements; Correction
The FAA is correcting the final rule, ``Harmonization of Airworthiness StandardsGust and Maneuver Load Requirements'' (79 FR 73462), published December 11, 2014. In the rule, the FAA amended certain airworthiness regulations for transport category airplanes to eliminate regulatory differences between the airworthiness standards of the FAA and European Aviation Safety Agency (EASA). It does not add new requirements beyond what manufacturers currently meet for EASA certification and does not affect current industry design practices. This final rule revises the pitch maneuver design loads criteria; revises the gust and turbulence design loads criteria; revises the application of gust loads to engine mounts, high lift devices, and other control surfaces; adds a ``round-the-clock'' discrete gust criterion and a multi-axis discrete gust criterion for airplanes equipped with wing-mounted engines; revises the engine torque loads criteria; adds an engine failure dynamic load condition; revises the ground gust design loads criteria; revises the criteria used to establish the rough air design speed; and requires the establishment of a rough air Mach number. This document corrects errors in the rule by ensuring that certain letters in the included equations have the right formatting and therefore the correct meaning.
Airworthiness Directives; Airbus Airplanes
We are adopting a new airworthiness directive (AD) for all Airbus Model A330-200, A330-200 Freighter, and A330-300 series airplanes. This AD requires revising the electrical emergency configuration procedure in the Emergency Procedures section of the airplane flight manual (AFM) to include procedures for deploying the ram air turbine manually to provide sufficient hydraulic power and avoid constant speed motor/generator (CSM/G) shedding. This AD was prompted by an electrical load analysis that revealed that hydraulic power might not be sufficient to supply the CSM/G during slat/flap extension when only one engine is running. We are issuing this AD to prevent such a condition which, in conjunction with the loss of the main electrical system, could lead to the scenario where the flightcrew is not clearly warned that the electrical system has switched on the battery and thus has a limited duration that would allow a safe landing.
Airworthiness Directives; The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 717-200 airplanes; Model DC-10-10, DC-10-10F, DC- 10-15, DC-10-30, DC-10-30F (KC-10A and KDC-10), DC-10-40 and DC-10-40F airplanes; Model MD-10-10F and MD-10-30F airplanes; Model DC-9-81 (MD- 81), DC-9-82 (MD-82), DC-9-83 (MD-83), and DC-9-87 (MD-87) airplanes; Model MD-88 airplanes; and Model MD-90-30 airplanes. This AD was prompted by reports of latent air data transducer degradation.

AD 2011-23-01 required replacement of certain P/N and S/N clutch assemblies. This AD requires the same actions but expands the population of affected P/N and S/N clutch assemblies. This AD was prompted by an additional report of a clutch assembly that malfunctioned due to disk springs that received a nonconforming heat treatment process. We are issuing this AD to prevent failure of the clutch assembly, which could lead to failure of the engine, in-flight shutdown, and loss of control of the airplane.
Airworthiness Directives; Viking Air Limited Airplanes
We are adopting a new airworthiness directive (AD) for Viking Air Limited Models DHC-2 Mk. I, DHC-2 Mk. II, and DHC-2 Mk. III airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as failed locknuts on the horizontal stabilizer attach bracket. We are issuing this AD to require actions to address the unsafe condition on these products.
Deadline for Notification of Intent To Use the Airport Improvement Program (AIP) Primary, Cargo, and Nonprimary Entitlement Funds for Fiscal Year 2015
The Federal Aviation Administration (FAA) announces May 1, 2015, as the deadline for each airport sponsor to notify the FAA whether or not it will use its fiscal year 2015 entitlement funds available under Section 47114 of Title 49, United States Code, to accomplish Airport Improvement Program (AIP)-eligible projects that the sponsor previously identified through the Airports Capital Improvement Plan (ACIP) process during the preceding year. The sponsor's notification must address all entitlement funds apportioned for fiscal year 2015, as well as any entitlement funds not obligated from prior years. After Thursday, July 2, 2015, the FAA will carry over all remaining entitlement funds, and the funds will not be available again until at least the beginning of fiscal year 2016. This notification requirement does not apply to non-primary airports covered by the block-grant program.
Airworthiness Directives; Airbus Airplanes
We are superseding Airworthiness Directive (AD) AD 2011-14-06 for all Airbus Model A318, A319, A320, and A321 series airplanes. AD 2011-14-06 required revising the maintenance program. This new AD requires revising the maintenance program to incorporate new, more restrictive limitations. This AD was prompted by the determination that more restrictive limitations are necessary. We are issuing this AD to prevent fatigue cracking, accidental damage, or corrosion in principal structural elements, and possible failure of certain life limited parts, which could result in reduced structural integrity of the airplane.
Airworthiness Directives; ATR-GIE Avions de Transport Régional Airplanes
We propose to adopt a new airworthiness directive (AD) for all ATRGIE Avions de Transport R[eacute]gional Model ATR42 airplanes. This proposed AD was prompted by several reports of a cracked floor beam at frame (FR) 26, and of discrepancies in certain wing inspection tasks in maintenance documents that could lead to errors in scheduling inspection intervals of structurally significant items (SSIs). This proposed AD would require repetitive inspections of certain floor beams and revision of the maintenance or inspection program to include inspections of several areas of the wings. We are proposing this AD to detect and correct any cracking of the floor beam at FR 26 and several areas of the wings, which could lead to reduced structural integrity of the airplane.
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 reports of fluid entry and accumulation in the aft equipment bay. This proposed AD would require modifying the aft equipment bay. We are proposing this AD to prevent excessive quantities of flammable fluid accumulation in the aft equipment bay. Flammable fluid entry and accumulation in the aft equipment bay, in excessive quantities, could exceed safe levels maintained by the drainage and ventilation system.
Aviation Rulemaking Advisory Committee-New Task
The FAA assigned the Aviation Rulemaking Advisory Committee (ARAC) a new task to provide recommendations regarding revision of the damage-tolerance and fatigue requirements of Title 14, Code of Federal Regulations (14 CFR), part 25, including subparts C and E of 14 CFR part 26, and development of associated advisory material for metallic, composite, and hybrid structures. Past changes to the damage-tolerance and fatigue airworthiness standards and advisory material have been more specific to transport airplanes constructed predominantly of metal, using skin-stringer-frame architecture. Today, the trend in industry is to use more composite and hybrid structures (i.e., structure that includes a combination of composite and metallic parts and assemblies) to improve the performance of transport airplanes. As a result, the damage-tolerance and fatigue airworthiness standards and advisory material may not be adequate to address this trend. This notice informs the public of the new ARAC activity and solicits membership for the new Transport Airplane Metallic and Composite Structures Working Group.

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 possible cracking from stress corrosion on various parts of the airplane structure made of aluminum alloy AA2024-T351. We are issuing this AD to require actions to address the unsafe condition on these products.
Airworthiness Directives; Airbus Airplanes
We are superseding Airworthiness Directive (AD) 2011-13-09 for all Airbus Model A330-200, -200F, and -300 series airplanes. AD 2011- 13-09 required revising the maintenance program to incorporate new limitations and maintenance tasks for certain certification management requirements (CMRs). This new AD requires revising the maintenance or inspection program to incorporate new 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.
Notice of Intent To Release Airport Property for Non-Aeronautical Use; Plymouth Municipal Airport, Plymouth, MA
The Federal Aviation Administration is considering a proposal to release of two parcels of approximately 27.3 acres of airport property for non-aeronautical use at the Plymouth Municipal Airport, Plymouth, MA. The released parcels would serve as part of the mitigation for an Army Corps of Engineers conservation project. The airport acreage to be released is currently used as a buffer zone and is not needed for current and future airport development. In exchange, the Airport would receive 41.5 acres of land that would be used for conservation. In accordance with section 47107(h) of Title 49 of the United States Code, the FAA invites public comment on this proposal.

Eighth Meeting: RTCA Tactical Operations Committee (TOC)
The FAA is issuing this notice to advise the public of the seventh meeting of the RTCA Tactical Operations Committee.
Airworthiness Directives; Cessna Aircraft Company Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Cessna Aircraft Company Model 500, 501, 550, 551, S550, 560, and 650 airplanes. This proposed AD was prompted by reports of smoke and/or fire in the tailcone caused by sparking due to excessive wear of the brushes in the air conditioning (A/C) motor. This proposed AD would require inspections to determine if certain A/C compressor motors are installed and to determine the accumulated hours on certain A/C compressor motor assemblies; and repetitive replacement of the brushes in the A/C compressor motor assembly, or, as an option to the brush replacement, deactivation of the A/C system and placard installation; and return of replaced brushes to Cessna. We are proposing this AD to prevent the brushes in the A/C motor from wearing down beyond their limits, which could result in the rivet in the brush contacting the commutator, causing sparks and consequent fire and/or smoke in the tailcone with no means to detect or extinguish the fire and/or smoke.
Airworthiness Directives; Airbus Airplanes
We propose to adopt a new airworthiness directive (AD) for all Airbus Model A330-200, A330-200 Freighter, and A330-300 series airplanes; and Model A340-200 and A340-300 series airplanes. This proposed AD was prompted by reports of cracked support strut body ends at a certain frame location of the trimmable horizontal stabilizer (THS). This proposed AD would require repetitive inspections for cracking of the strut ends of the THS support located at a certain frame in the tail cone, and replacement if necessary; and reinstallation or installation of reinforcing clamps on certain strut ends. We are proposing this AD to detect and correct cracked support strut body ends of the THS, which could lead to the loss of all four THS support struts and which would make the remaining structure unable to carry limit loads, resulting in the loss of the horizontal tail plane.
Airworthiness Directives; The Boeing Company Airplanes
We propose to supersede Airworthiness Directive (AD) 2013-26- 08, which applies to certain The Boeing Company Model 737-600, -700, - 700C, -800, -900, and -900ER series airplanes. AD 2013-26-08 currently requires inspecting the orientation of both sides of the coil cord connector keyways of the number 2 windows on the flight deck; re- clocking the connector keyways, if necessary; and replacing the coil cord assemblies on both number 2 windows on the flight deck. Since we issued AD 2013-26-08, we have determined that additional airplanes are subject to the identified unsafe condition. This proposed AD would add airplanes to the applicability. We are proposing this AD to prevent arcing, smoke, and fire in the flight deck, which could lead to injuries to or incapacitation of the flightcrew.
Airworthiness Directives; Airbus Airplanes
We propose to adopt a new airworthiness directive (AD) for all Airbus Model A330-200, A330-200 Freighter, and A330-300 series airplanes; and Airbus Model A340-200, A340-300, A340-500, and A340-600 series airplanes. This proposed AD was prompted by a report that, during a production flight test, the ram air turbine (RAT) did not pressurize the green hydraulic system. For certain airplanes, this proposed AD would require identification of the part number, serial number, and standard of the RAT pump, RAT module, RAT actuator, and RAT lower gearbox assembly; replacement of the balance weight screw, modification of the actuator coil spring, modification of the actuator, an inspection of the anti-stall valve for correct installation in the RAT pump housing; and corrective actions if necessary. For certain other airplanes, this proposed AD would require re-identification or replacement of the RAT module. We are proposing this AD to prevent loss of the impeller function and RAT pump pressurization capability, which, if preceded by a total engine flame-out, could result in the 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 CL-600-2E25 (Regional Jet Series 1000) airplanes. This proposed 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 proposed AD would require revising the maintenance or inspection program, as applicable, to incorporate a maintenance task for an operational check of the electro-mechanical actuator (EMA) and release mechanism of the alternate extension system (AES) for the nose landing gear (NLG) and main landing gear (MLG). We are proposing 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; Fokker Services B.V. Airplanes
We propose to adopt a new airworthiness directive (AD) for all Fokker Services B.V. Model F.28 Mark 0070 and 0100 airplanes. This proposed AD was prompted by reports that cracks can occur in a frame of the tail section on certain airplanes. This proposed AD would require a one-time detailed inspection of the oblique frame 67-2 for any cracking, and repair if necessary. We are proposing this AD to detect and correct such cracking, which could lead to failure of the oblique frame 67-2, and consequent loss of the structural integrity of the tail section.
Airworthiness Directives; Bombardier, Inc., Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. This proposed AD was prompted by reports of the horizontal stabilizer trim actuator (HSTA) spur gear bolts inside the gearbox found loose, broken, or backed out due to incorrect bending of the anti-rotation tab washer and the improper application of glue during installation. This proposed AD would require replacing certain HSTAs with a new HSTA. This proposed AD would also require revising the airplane flight manual (AFM) and the maintenance or inspection program, as applicable. We are proposing this AD to prevent failure of the HSTA and subsequent 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 an in-service report of an uncommanded and unannunciated nose wheel steering during airplane pushback from the gate. This proposed AD would require installing new cable assemblies with a pull-down resistor. We are proposing this AD to prevent an uncommanded nose wheel steering during takeoff or landing in the event of an open circuit in the steering system, and possible consequent runway excursion.
Airworthiness Directives; ATR-GIE Avions de Transport Régional Airplanes
We propose to adopt a new airworthiness directive (AD) for certain ATR-GIE Avions de Transport R[eacute]gional Model ATR42-500 and Model ATR72-212A airplanes. This proposed AD was prompted by a report indicating interference between a Type III Emergency Exit door and the surrounding passenger cabin furnishing during a production check. This proposed AD would require measuring the gap between the Type III Emergency Exit doors and certain overhead stowage compartment fittings; removing certain fittings from the overhead stowage compartments and measuring the gap between the Type III Emergency Exit doors and the overhead stowage compartment hooks, if necessary; and re-installing or repairing, as applicable, the Type III Emergency Exit doors. We are proposing this AD to detect and correct interference between a Type III Emergency Exit door and the overhead stowage compartment fitting installed on the rail; which could result in obstructed opening of a Type III Emergency Exit door during an emergency evacuation.
Airworthiness Directives; The Boeing Company Airplanes
We propose to supersede Airworthiness Directive (AD) 2004-13- 02, which applies to certain The Boeing Company Model 747-100, -200B, and -200F series airplanes. AD 2004-13-02 currently requires initial and repetitive inspections to find discrepancies in the upper and lower skins of the fuselage lap joints, and repair if necessary. Since we issued AD 2004-13-02, an evaluation by the design approval holder (DAH) indicates that the longitudinal lap joints are subject to widespread fatigue damage (WFD), and that a structural modification at the lap joint, and post-modification repetitive inspections of the skin, existing internal doubler, or splice strap for cracks, and corrective actions if necessary, are required to reach the limit of validity (LOV). This proposed AD would add post-repair inspections for cracking and corrosion, and repair if necessary; structural modification at the lap joints; and post-modification inspections for cracking and corrosion, and repair if necessary. We are proposing this AD to detect and correct fatigue cracking in the upper and lower skins of the fuselage lap joints, which could result in sudden fracture and failure of a lap joint and rapid in-flight decompression of the airplane fuselage.
Airworthiness Directives; Airbus Airplanes
We propose to adopt a new airworthiness directive (AD) for all Airbus Model A310 and Airbus 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) series airplanes. This proposed AD was prompted by a report of skin disbonding and damage found on the composite side panel of the rudder, located between the rudder core and skin of a previously repaired area. This proposed AD would require an inspection for disbonding or damage of certain rudders, and related investigative actions and corrective actions if necessary. We are proposing this AD to detect and correct disbonding and damage of the rudder, which could result in reduced structural integrity of the rudder and consequent reduced controllability of the airplane.
