Airworthiness Directives; Boeing Model 777-200, -200LR, -300, and -300ER Series Airplanes Approved for Extended-Range Twin-Engine Operational Performance Standards (ETOPS)
We are adopting a new airworthiness directive (AD) for certain Boeing Model 777-200, -200LR, -300, and -300ER series airplanes. This AD requires a one-time inspection to determine the part number of the cargo compartment fire suppression filter/regulator. This AD also requires, for certain airplanes, a revision of the ``Maximum Diversion Time in Minutes'' for ETOPS operation specified in the Operations Specifications. For certain airplanes, this AD also provides for optional replacement of the cargo compartment fire suppression filter/ regulator, which would allow revision of the ``Maximum Diversion Time in Minutes'' for ETOPS operation specified in the Operations Specifications to restore the airplane's full ETOPS capability. This AD results from a report that the filter/regulator installed in the cargo fire suppression system did not meter the Halon for the certified duration during ETOPS flight tests. We are issuing this AD to prevent ETOPS operation with insufficient cargo fire suppression capability, which could result in an uncontained fire in the cargo compartment.

Airworthiness Directives; Boeing Model 737-300 and -400 Series Airplanes
We are adopting a new airworthiness directive (AD) for certain Boeing Model 737-300 and -400 series airplanes. This AD requires testing and inspecting a certain web panel of the main wheel well pressure deck to determine the material type and thickness; and related investigative and corrective actions if necessary. This AD results from several reports indicating that cracks ranging from 0.8 to 8.0 inches long were found on a certain web panel of the main wheel well pressure deck. We are issuing this AD to prevent fatigue cracking in the web panel of the main wheel well pressure deck, which could result in venting and consequent decompression of the airplane.
Airworthiness Directives; McDonnell Douglas Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD-83), DC-9-87 (MD-87), and MD-88 Airplanes
We are adopting a new airworthiness directive (AD) for all McDonnell Douglas Model DC-9-81 (MD-81), DC-9-82 (MD-82), DC-9-83 (MD- 83), DC-9-87 (MD-87), and MD-88 airplanes. This AD requires repetitive inspections for cracking of the overwing frames from stations 845 to 905 (MD-87 stations 731 to 791), left and right sides, and corrective actions if necessary. This AD results from reports of cracked overwing frames. We are issuing this AD to detect and correct such cracking, which could sever the frame, increase the loading of adjacent frames, and result in damage to adjacent structure and loss of overall structural integrity of the airplane.
Airworthiness Directives; Boeing Model 737-100, -200, -200C, -300, -400, and -500 Series Airplanes
We are adopting a new airworthiness directive (AD) for certain Boeing Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This AD requires various repetitive inspections for cracking of the upper frame to side frame splice of the fuselage, and other specified and corrective actions if necessary. This AD also provides for an optional preventive modification, which terminates the repetitive inspections. This AD results from a report that the upper frame of the fuselage was severed between stringers S-13L and S-14L at station 747, and the adjacent frame at station 767 had a 1.3-inch-long crack at the same stringer location. We are issuing this AD to detect and correct fatigue cracking of the upper frame to side frame splice of the fuselage, which could result in reduced structural integrity of the frame and adjacent lap joint. This reduced structural integrity can increase loading in the fuselage skin, which will accelerate skin crack growth and result in decompression of the airplane.
Airworthiness Directives; Lockheed Model 1329 Series Airplanes
We are adopting a new airworthiness directive (AD) for certain Lockheed Model 1329 series airplanes. This AD requires determining the part number on the steering cylinder assembly for the nose landing gear (NLG), determining the total flight cycles accumulated on the NLG steering cylinder assembly, repetitively replacing the assembly, inspecting for missing tow turning limit markings, and performing corrective actions if necessary. This AD results from reports of numerous failures of the NLG steering cylinder. We are issuing this AD to prevent the loss of hydraulic pressure and steering control.
Airworthiness Directives; Gulfstream Aerospace LP Model Astra SPX, 1125 Westwind Astra, and Gulfstream 100 Airplanes

We are adopting a new airworthiness directive (AD) for certain Airbus Model A330 airplanes and Model A340-200 and -300 series airplanes. This AD requires revising the airplane flight manual (AFM) to prohibit the flightcrew from performing CAT 2 and CAT 3 automatic landings and roll-outs at certain airports. This AD also provides an optional terminating action for the AFM revision. This AD results from data showing that the magnetic variation table installed in certain Honeywell and Northrop Grumman air data inertial reference units (ADIRUs) is obsolete at certain airports. We are issuing this AD to prevent the airplane from departing the runway during a CAT 2 or CAT 3 automatic landing or roll-out, due to differences between actual magnetic variation and the values in the ADIRU magnetic variation tables.

Proposed Establishment of Low Altitude Area Navigation Route (T-Route); Houston, TX
This action proposes to establish a low altitude Area Navigation (RNAV) route, designated T-254, in the Houston, TX, terminal area. T-routes are low altitude Air Traffic Service routes, based on RNAV, for use by aircraft that have instrument flight rules (IFR) approved Global Positioning System (GPS)/Global Navigation Satellite System (GNSS) equipment. This action would enhance safety and improve the efficient use of the navigable airspace in the Houston, TX, terminal area.
Airworthiness Directives; Fokker Model F.28 Mark 0070 and Mark 0100 Airplanes
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Fokker Model F.28 Mark 0070 and 0100 airplanes. The existing AD currently requires a one-time inspection of the main landing gear (MLG) main fitting for cracks, and repair if necessary. The existing AD also currently requires installing a placard and revising the airplane flight manual to include procedures to prohibit the application of brakes during backward movement of the airplane. This proposed AD would require repetitive eddy current inspections of the MLG main fitting and rework before further flight as applicable. This proposed AD results from reports that a final solution eliminating the cause of the crack initiation mechanism is not yet available and that repetitive inspections are necessary. We are proposing this AD to detect and correct cracks in the MLG main fitting, which could result in reduced structural integrity of the MLG main fitting.
Airworthiness Directives; Boeing Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, 747SR, and 747SP Series Airplanes
The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all Boeing Model 747 series airplanes. The existing AD currently requires repetitive detailed inspections of the aft pressure bulkhead for indications of ``oil cans'' and previous oil can repairs, and corrective actions, if necessary. An oil can is an area on a pressure dome web that moves when pushed from the forward side. This proposed AD would reduce the compliance time for the initial detailed inspection and clarify the applicability. This proposed AD results from a report that cracks in oil-canned areas were found during an inspection of the aft pressure bulkhead. We are proposing this AD to detect and correct the propagation of fatigue cracks in the vicinity of oil cans on the web of the aft pressure bulkhead, which could result in rapid decompression of the airplane and overpressurization of the tail section, and consequent loss of control of the airplane.
Airworthiness Directives; Fokker Model F.28 Mark 0070 and 0100 Airplanes
We propose to adopt a new airworthiness directive (AD) for the products listed above. 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:
Airworthiness Directives; Bombardier Model DHC-8-400, DHC-8-401, and DHC-8-402 Airplanes
We propose to adopt a new airworthiness directive (AD) for the products listed above. 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:
Establishment of Class E Airspace; Salida, CO
This action will establish Class E airspace at Salida, CO. Controlled airspace is necessary to accommodate aircraft using a new Area Navigation (RNAV) Global Positioning System (GPS) Standard Instrument Approach Procedure (SIAP) at Harriet Alexander Field. This will improve the safety of Instrument Flight Rules (IFR) aircraft executing the new RNAV GPS SIAP at Harriet Alexander Field, Salida, CO.
Airworthiness Directives; Hartzell Propeller Inc. ( )HC-( )(2,3)Y(K,R)-2 Two- and Three-Bladed Compact Series Propellers
The FAA is adopting a new airworthiness directive (AD) for Hartzell Propeller Inc. left-hand rotating ( )HC-( )(2,3)Y(K,R)-2 two- and three-bladed, aluminum hub, ``compact'' series propellers, with hubs having a non-suffix serial number, and lubrication holes located on the shoulder of the hub blade socket. These propellers are installed on Lycoming Engines LIO-360 series and LO-360 series reciprocating engines installed on Piper Aircraft, Inc. Seneca PA-34-200 and Seminole PA-44-180, and Hawker Beechcraft Corporation Model 76 Duchess, airplanes. This AD requires initial and repetitive eddy current inspections (ECI), of the area around the lubrication holes of the hub blade sockets. This AD results from four reports of propeller hub cracks, including two in-flight blade separation events. We are issuing this AD to prevent failure of the propeller hub, which could result in blade separation and loss of control of the airplane.
Airworthiness Directives; Turbomeca S.A. Arrius 2F Turboshaft Engines
We are adopting a new airworthiness directive (AD) for the products listed above. 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.

Airworthiness Directives; Boeing Model 757 Airplanes Equipped With Rolls Royce RB211-535E Engines
We are adopting a new airworthiness directive (AD) for certain Boeing Model 757 airplanes equipped with Rolls Royce RB211-535E engines. This AD requires repetitive inspections for signs of damage of the aft hinge fittings and attachment bolts of the thrust reversers, and related investigative and corrective actions if necessary. This AD results from reports of several incidents of bolt failure at the aft hinge fittings of the thrust reversers due to, among other things, high operational loads. We are issuing this AD to prevent failure of the attachment bolts and consequent separation of a thrust reverser from the airplane during flight, which could result in structural damage to the airplane.
Airworthiness Directives; Boeing Model 767-200, -300, and -400ER Series Airplanes
We are adopting a new airworthiness directive (AD) for certain Boeing Model 767-200, -300, and -400ER series airplanes. This AD requires an inspection to determine the manufacturer and manufacture date of the oxygen masks in the passenger service units and the flight attendant and lavatory oxygen boxes, as applicable. This AD also requires related investigative/corrective actions if necessary. This AD results from a report that several passenger masks with broken in-line flow indicators were found following a mask deployment. We are issuing this AD to prevent the in-line flow indicators of the passenger oxygen masks from fracturing and separating, which could inhibit oxygen flow to the masks and consequently result in exposure of the passengers and cabin attendants to hypoxia following a depressurization event.
Airworthiness Directives; Boeing Model 747-400, 747-400D, and 747-400F Series Airplanes
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 747-400, 747-400D, and 747-400F series airplanes. This AD requires replacement of an electronic flight instrument system/ engine indicating and crew alerting system (EFIS/EICAS) interface unit (EIU) located on the E2-6 shelf of the main equipment center with a new or modified EIU. This AD results from two instances where all six integrated display units (IDUs) on the flight deck panels went blank in flight. We are issuing this AD to prevent loss of the IDUs due to failure of all three EIUs, which could result in the inability of the flightcrew to maintain safe flight and landing of the airplane.
Airworthiness Directives; Hawker Beechcraft Corporation (Type Certificates No. 3A15, No. 3A16, No. A23CE, and No. A30CE Previously Held by Raytheon Aircraft Company) F33 Series and Models G33, V35B, A36, A36TC, B36TC, 95-B55, D55, E55, A56TC, 58, 58P, 58TC, G58, and 77 Airplanes
The FAA adopts a new airworthiness directive (AD) for certain Hawker Beechcraft Corporation F33 series and Models G33, V35B, A36, A36TC, B36TC, 95-B55, D55, E55, A56TC, 58, 58P, 58TC, G58, and 77 airplanes. This AD requires you to replace certain circuit breaker toggle switches with improved design circuit breaker toggle switches. This AD results from reports of certain circuit breaker toggle switches used in various electrical systems throughout the affected airplanes overheating. We are issuing this AD to prevent failure of the circuit breaker toggle switch, which could result in smoke in the cockpit and the inability to turn off the switch.
Airworthiness Directives; Bombardier Model DHC-8-400 Series Airplanes
We are adopting a new airworthiness directive (AD) for the products listed above. This 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:
Advisory Circulars: Extended Operations (ETOPS) and Polar Operations, AC 121-42B and Extended Operations (ETOPS) and Operations in the North Polar Area, AC 135-42
The issuance of Advisory Circular (AC) 121-42B, Extended Operations (ETOPS) and Polar Operations, provides certificate holders with guidance for obtaining operational approval to conduct ETOPS under 14 CFR part 121. The issuance of AC 135-42, Extended Operations (ETOPS) and Operations in the North Polar Area, provides certificate holders with guidance for obtaining operational approval to conduct Extended Operations (ETOPS) under 14 CFR part 135.
Airworthiness Directives; Eurocopter France Model AS 355 N Helicopters
We are adopting a new airworthiness directive (AD) for Eurocopter France Model AS 355 N helicopters. This 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 European Aviation Safety Agency (EASA), the technical agent for France, with which we have a bilateral agreement, states in the MCAI: ``This Airworthiness Directive (AD) is issued because it was found that the power drawn by the starter generators from the engines is above the consumption capacity at altitudes above 3,000 meters, declared for the engines of AS 355 N helicopters. Excessive power consumption of the starter generators reduces the engine surge margin, which can result in engine failure.'' After engine start, the starter generator functions as the normal operational electrical generator. We are issuing this AD to require actions that are intended to address this unsafe condition.
Standard Instrument Approach Procedures, and Takeoff Minimums and Obstacle Departure Procedures; Miscellaneous Amendments
This Rule establishes, amends, suspends, or revokes STANDARD Instrument Approach Procedures (SIAPs) and associated Takeoff Minimums and Obstacle Departure Procedures for operations at certain airports. These regulatory actions are needed because of the adoption of new or revised criteria, or because of changes occurring in the National Airspace System, such as the commissioning of new navigational facilities, adding new obstacles, or changing air traffic requirements. These changes are designed to provide safe and efficient use of the navigable airspace and to promote safe flight operations under instrument flight rules at the affected airports.
