Eighth Meeting: RTCA Special Committee 225, Rechargeable Lithium Battery and Battery Systems-Small and Medium Sizes
The FAA is issuing this notice to advise the public of the eighth meeting of RTCA Special Committee 225, Rechargeable Lithium Battery and Battery SystemsSmall and Medium Sizes.
Air Traffic Procedures Advisory Committee
The FAA is issuing this notice to advise the public of its environmental review of four standard instrument departure procedures at LaGuardia International Airport (LGA). As required by the National Environmental Policy Act, an evaluation has been performed on the four proposed standard instrument departure procedures to determine the level of environmental review warranted. The FAA has elected to ``Categorically Exclude from further environmental review'' the four proposed departure procedures identified as GLDMN FOUR (RNAV) Runway 13, NTHNS TWO (RNAV) Runway 13, HOPEA ONE (RNAV) Runway 22, and JUTES ONE (RNAV) Runway 22.
Airworthiness Directives; the Boeing Company Airplanes
We are revising an earlier proposed airworthiness directive (AD) to supersede an existing AD for all The Boeing Company Model 767 airplanes. The existing AD currently requires repetitive inspections to detect discrepancies of the wiring and surrounding Teflon sleeves of the fuel tank boost pumps and override/jettison pumps; replacement of the sleeves with new sleeves, for certain airplanes; and repair or replacement of the wiring and sleeves with new parts, as necessary. The previous NPRM proposed to reduce the initial compliance time and repetitive inspection interval in the existing AD. The previous NPRM was prompted by fleet information indicating that the repetitive inspection interval in the existing AD is too long because excessive chafing of the sleeving continues to occur much earlier than expected between scheduled inspections. This action revises the previous NPRM by proposing a terminating action for the repetitive inspections, to eliminate wire damage. This action also removes certain airplanes from the applicability of the previous NPRM. We are proposing this supplemental NPRM to detect and correct chafing of the fuel pump wire insulation and consequent exposure of the electrical conductor, which could result in electrical arcing between the wires and conduit and consequent fire or explosion of the fuel tank. Since these actions impose an additional burden over that proposed in the previous NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.
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 reports of the escape slide of the raft inflation system not deploying when activated due to the rotation of the cable guide in a direction which resulted in jamming of the inflation control cable. This proposed AD would require modifying the affected slide rafts. We are proposing this AD to prevent non-deployment of the inflation system of the escape slide raft, which could result in delayed evacuation from the airplane during an emergency, and consequent injury to the passengers.
Combined Drug and Alcohol Testing Programs
This rulemaking would allow air carrier operators and commuter or on-demand operators that also conduct commercial air tour operations to combine the drug and alcohol testing required for each operation into one testing program. The current rule requires those operators to conduct separate testing programs for their air tour operations. This results in an unnecessary duplication of effort. The intended effect of this rulemaking is to decrease operating costs by eliminating the requirement for duplicate programs while maintaining the level of safety intended by the current drug and alcohol testing regulations. This proposal would also clarify existing instructions within the rule, correct an inadvertent typographical error, clarify an existing requirement by rearranging its numerical order, and remove language that describes a practice that has been discontinued.
Airworthiness Directives; Rolls-Royce plc Turbofan Engines
We are superseding an existing airworthiness directive (AD) for all Rolls-Royce plc (RR) models RB211-Trent 970-84, 970B-84, 972- 84, 972B-84, 977-84, 977B-84, and 980-84 turbofan engines. That AD currently requires inspecting the intermediate-pressure (IP) shaft rigid coupling splines for wear resulting in rearward movement of the IP turbine. This AD requires the same inspections, and new inspections based on possible changes in wear rate. This AD was prompted by RR identifying wear beyond engine manual limits on the abutment faces of the splines. RR also determined that an additional IP shaft rigid coupling configuration requires inspection. We are issuing this AD to detect wear on the abutment faces of the splines, which could result in loss of disc integrity, an uncontained failure of the engine, and damage to the airplane.
Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG (RRD) Turbofan Engines
We are rescinding an airworthiness directive (AD) for RRD BR700-715A1-30, BR700-715B1-30, and BR700-715C1-30 turbofan engines. The existing AD resulted from the need to reduce the published life limits of high-pressure (HP) turbine stage 1 discs, part numbers (P/Ns) BRH20130 and BRH20131, and HP turbine stage 2 discs, P/Ns BRH19423 and BRH19427. We are rescinding the existing AD because RRD has revised the approved published life limits of these parts to the same or higher limits as originally certified.
Airworthiness Directives; The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This AD requires inspecting parts or doing a records review to determine if certain trailing edge flap carriages are installed, doing repetitive inspections for corrosion, and flaking or missing thermal coating on suspect carriage spindles, and related investigative and corrective actions, if necessary; this AD also provides optional terminating action for the repetitive inspections. This AD was prompted by reports of corrosion found on carriage that are located on the outboard flaps. We are issuing this AD to detect and correct corrosion of the carriage spindle, which could result in a fracture; fracture of both the inboard and outboard carriage spindles, at the forward ends through the large diameters, on a single flap assembly, could adversely affect the continued safe flight and landing of the airplane.
Airworthiness Directives; Empresa Brasileria de Aeronáutica S.A. (EMBRAER) Airplanes
We are adopting a new airworthiness directive (AD) for certain Empresa Brasileria de Aeron[aacute]utica S.A. (EMBRAER) Model EMB-505 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 an inadequate amount of drain holes in the primary control surfaces (rudder, elevator, and aileron) and their tab surfaces, which may allow water to accumulate in the control surfaces. This condition could cause unbalanced flight control surfaces and reduced flutter margins, which could result in loss of control of the airplane. We are issuing this AD to require actions to address the unsafe condition on these products.
