Airworthiness Directives; Rolls-Royce Corporation AE 3007A and AE 3007C Series Turbofan Engines
The FAA proposes to supersede an existing airworthiness directive (AD) for Rolls-Royce Corporation (RRC) AE 3007A and AE 3007C series turbofan engines. That AD currently prohibits any flight following a ground engine start where the engine oil temperature is below 32 [deg]F (0 [deg]C), unless certain preflight operational procedures are followed. This proposed AD would also require those actions, and would also require a terminating action. This proposed AD would supersede the compliance requirements of AD 99-02-51 and all related alternative methods of compliance (AMOCs). This proposed AD results from design improvements to components in the accessory gearbox air turbine starter mounting pad. We are proposing this AD to prevent an in-flight engine shutdown due to loss of engine oil from the starter shaft seal.
Airworthiness Directives; Bombardier Model DHC-8-100, DHC-8-200, and DHC-8-300 Series Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Bombardier Model DHC-8-100, DHC-8-200, and DHC-8-300 series airplanes. This proposed AD would require, for certain airplanes, modification of the upper bearing of the main landing gear (MLG) shock strut. This proposed AD would also require, for certain airplanes, revising the DHC-8 Maintenance Program Manual to include the MLG shock strut servicing task. This proposed AD results from reports of over-extension of the MLG shock strut piston, which allows the torque links to go over-center and rest on the piston. We are proposing this AD to prevent loss in shock absorption during touchdown and failure of the shock strut housing, which could result in a subsequent loss of directional control.
Airworthiness Directives; Boeing Model 747 Airplanes
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Boeing Model 747 series airplanes. The existing AD requires a one-time inspection of the potable water and drain lines in the cargo compartments for indications of overheating of the heater tape, exposed foam insulation, missing or damaged protective tape, or debris around the potable water fill and drain lines; and corrective action, if necessary. This proposed AD would require that the inspection of the water and drain lines be repetitively performed, using new service information, until new ribbon heaters are installed, which would terminate the repetitive inspections. This AD would also remove certain airplanes from the applicability. This proposed AD results from a report of a fire in the aft cargo compartment started by a potable water line heater tape. We are proposing this AD to prevent overheating of the heater tape on potable water fill and drain lines, which could ignite accumulated debris or contaminants on or near the potable water fill and drain lines, resulting in a fire in the airplane.
Airworthiness Directives; Airbus Model A319-100 and A320-200 Series Airplanes
The FAA is revising an earlier NPRM for an airworthiness directive (AD) that applies to certain Airbus Model A319-100 and A320- 200 series airplanes. The original NPRM would have required repetitive inspections of the wing-tank fuel pumps, canisters, and wing fuel tanks for detached identification labels, and corrective action if necessary. The original NPRM resulted from several incidents of detached plastic identification labels found floating in the wing fuel tanks. This action revises the original NPRM by expanding the applicability and mandating modification of the fuel strainers at the fuel pump and suction bypass intakes. We are proposing this supplemental NPRM to prevent plastic identification labels being ingested into the fuel pumps and consequently entering the engine fuel feed system, which could result in an engine shutdown.
FAA Civil Penalty Adjudication Web Site
The FAA has a Web site that provides access to many documents relating to the agency's administrative adjudication of civil penalty cases. Currently, the address provided in the regulations for the civil penalty adjudication Web site is incorrect. In this rulemaking, we are amending the regulations to substitute the correct Web site address.
