Federal Aviation Administration August 26, 2014 – Federal Register Recent Federal Regulation Documents

Airworthiness Directives; Bombardier, Inc. Airplanes
Document Number: 2014-20263
Type: Proposed Rule
Date: 2014-08-26
Agency: Federal Aviation Administration, Department of Transportation
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 reports of chafing of the fuel lines due to contact with the surrounding structures in the fuel tank. This proposed AD would require replacing and modifying fuel lines, revising the maintenance or inspection program, as applicable, to include critical design configuration control limitations (CDCCL) and airworthiness limitation (AWL) items, and, for certain airplanes removing certain clamps and mounting hardware. We are proposing this AD to prevent chafing of the fuel lines in the fuel tank, which could result in potential ignition sources in the fuel tank in the event of a lightning strike and consequent fire or explosion.
Airworthiness Directives; Airbus Airplanes
Document Number: 2014-20262
Type: Proposed Rule
Date: 2014-08-26
Agency: Federal Aviation Administration, Department of Transportation
We propose to supersede Airworthiness Directive (AD) 2014-09- 05, for certain Airbus Model A330-200 and -300 series airplanes, and Model A340-200 and -300 series airplanes. AD 2014-09-05 currently requires repetitive inspections of certain sidestay upper cardan pins of the main landing gear (MLG), and associated nuts and retainer assemblies, and pin replacement if necessary. Since we issued AD 2014- 09-05, we have determined that a previously optional measurement is necessary to address the identified unsafe condition. We are proposing 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
Document Number: 2014-20261
Type: Proposed Rule
Date: 2014-08-26
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for all Airbus Model A318, A319, and A321 series airplanes; and Model A320-211, -212, -214, -231, -232, and -233 airplanes. This proposed AD was prompted by a report of corrosion found during the manufacturing process for some oxygen pipe assemblies that are used to supply oxygen to the flight crew. This proposed AD would require an inspection to determine the batch number or installation date of the oxygen pipe assembly that is installed at the end of the right-hand crew distribution line, and, if necessary, replacement of the pipe. We are proposing this AD to detect and correct corrosion, which could lead to blocked or reduced oxygen supply to a flight crew member during a decompression event or a smoke/fire event in the cockpit. Under certain conditions, corrosion particles could increase the risk of fire in the cockpit.
Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (Embraer) Airplanes
Document Number: 2014-20260
Type: Proposed Rule
Date: 2014-08-26
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for all Empresa Brasileira de Aeronautica S.A. (Embraer) Model EMB-135BJ airplanes. This proposed AD was prompted by a determination that more restrictive fuel limitations are needed. This proposed AD would require revising the maintenance or inspection program to incorporate new compliance times and fuel limitations. We are proposing this AD to detect and correct fatigue cracking of various structural elements and prevent ignition sources in the fuel system.
Airworthiness Directives; Airbus Airplanes
Document Number: 2014-20257
Type: Proposed Rule
Date: 2014-08-26
Agency: Federal Aviation Administration, Department of Transportation
We propose to supersede Airworthiness Directive (AD) 2011-13- 09 for all Airbus Model A330-200 and -300 series airplanes. AD 2011-13- 09 currently requires revising the maintenance program to incorporate new limitations and maintenance tasks for certain certification management requirements (CMRs). Since we issued AD 2011-13-09, we have determined that more restrictive maintenance requirements and airworthiness limitations are necessary. This proposed AD would require revising the maintenance or inspection program to incorporate new maintenance requirements and airworthiness limitations. We are proposing 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.
Airworthiness Directives; Bombardier, Inc. Airplanes
Document Number: 2014-20223
Type: Proposed Rule
Date: 2014-08-26
Agency: Federal Aviation Administration, Department of Transportation
We propose to supersede Airworthiness Directive (AD) 2014-03- 05, for certain Bombardier, Inc. Model BD-700-1A10 airplanes. AD 2014- 03-05 currently requires modification of the air data probes and sensors. Since we issued AD 2014-03-05, we have determined that additional airplanes are affected by the unsafe condition. This proposed AD would add airplanes to the applicability. We are proposing this AD to detect and correct an unannunciated failure of two pitot static probe heaters, which could affect controllability of the airplane in icing conditions.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2014-20221
Type: Proposed Rule
Date: 2014-08-26
Agency: Federal Aviation Administration, Department of Transportation
We propose to supersede Airworthiness Directive (AD) 2011-09- 11, which applies to certain The Boeing Company Model 777-200 and -300 series airplanes. AD 2011-09-11 currently requires repetitive inspections for hydraulic fluid contamination of the interior of the strut disconnect assembly; repetitive inspections for discrepancies of the interior of the strut disconnect assembly, if necessary; repetitive inspections of the exterior of the strut disconnect assembly for cracks, if necessary; corrective action if necessary; and an optional terminating action for the inspections. Since we issued AD 2011-09-11, we have received reports of side and top cover plates installed with missing fastener bolts, which results in an unsealed opening on the system disconnect assembly. This proposed AD would add, for certain airplanes, an inspection of the side and top cover plates to determine if all cover plate attach fasteners have been installed, and installing any missing fasteners including doing an inspection for damage, and repair if necessary. We are proposing this AD to detect and correct hydraulic fluid contamination, which can cause cracking of titanium parts in the system disconnect assembly; and also to detect and correct missing fasteners, which results in unsealed openings on the system disconnect assembly. Both unsafe conditions can compromise the engine firewall and result in fire hazards for both the engine compartment and the strut.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2014-20218
Type: Proposed Rule
Date: 2014-08-26
Agency: Federal Aviation Administration, Department of Transportation
We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 747-8F and 747-8 series airplanes. This proposed AD was prompted by reports of delamination damage to leading edge (LE) variable camber krueger (VCK) flaps. This proposed AD would require repetitive inspections to detect delamination damage of the lightning strike applique (LSA) on the LE VCK flaps, and corrective actions if necessary. We are proposing this AD to detect and correct delamination damage to the LE VCK flaps, which can reduce the lightning strike protection capability on the LE VCK flaps and result in an uncommanded motion of the trailing edge flap system. Such uncommanded flap motion, without shutdown of the trailing edge or leading edge flaps, may cause unexpected changes in lift, potentially resulting in asymmetric lift and loss of control of the airplane.
Airworthiness Directives; The Boeing Company Airplanes
Document Number: 2014-20204
Type: Proposed Rule
Date: 2014-08-26
Agency: Federal Aviation Administration, Department of Transportation
We propose to supersede Airworthiness Directive (AD) 98-22-10, which applies to certain The Boeing Company Model 737-100, -200, -200C, and -300 series airplanes. AD 98-22-10 currently requires repetitive inspections for cracking of the aft frame and frame support structure of the forward service doorway, and repair if necessary. AD 98-22-10 also provides for an optional terminating action for the repetitive inspection requirements of that AD. Since we issued AD 98-22-10, we have determined that additional inspections are needed, and that additional airplanes may be subject to the identified unsafe condition. This proposed AD would add inspections and add airplanes to the applicability. For certain airplanes, this proposed AD provides a preventive modification, which would terminate the repetitive inspections. We are proposing this AD to detect and correct fatigue cracking of the aft frame and frame support structure of the forward service doorway around the six doorstop fittings, which could result in door deflection and loss of pressurization.
