Airworthiness Directives; Airbus Model A330 and A340 Airplanes
The FAA withdraws a second supplemental NPRM for an airworthiness directive (AD) that applies to all Airbus Model A330-200, A330-300, A340-200, and A340-300 series airplanes; and Model A340-541 and A340-642 airplanes. That second supplemental NPRM proposed to revise the Airworthiness Limitations Section (ALS), for all affected airplanes, by adding new Airworthiness Limitations Items (ALIs) to incorporate service life limits for certain items and inspections to detect fatigue cracking, accidental damage or corrosion in certain structures, in accordance with the revised ALS of the Instructions for Continued Airworthiness. Since the second supplemental NPRM was issued, we have published new NPRMs to propose to mandate the most recent airworthiness limitations for Model A330-200 and -300 series airplanes; and new ADs to mandate the most recent airworthiness limitations for Model A340-200 and -300 series airplanes; and Model A340-541 and -642 airplanes. Accordingly, the proposed AD is withdrawn.
Proposed Amendment of Class E Airspace; Gary, IN
This action proposes to amend Class E airspace at Gary, IN, to accommodate new Standard Instrument Approach Procedures (SIAP) at Gary/ Chicago International Airport. The FAA is taking this action to enhance the safety and management of Instrument Flight Rules (IFR) operations for SIAPs at the airport. This action also would update the airport name.
Proposed Amendment of Class E Airspace; Hannibal, MO
This action proposes to amend Class E airspace at Hannibal, MO. Decommissioning of the Hannibal non-directional beacon (NDB) at Hannibal Regional Airport, Hannibal, MO, has made this action necessary for the safety and management of Instrument Flight Rules (IFR) operations at Hannibal Regional Airport. This action also would change the airport name to Hannibal Regional Airport, and update the geographic coordinates.
Proposed Amendment of Class E Airspace; Grand Marais, MN
This action proposes to amend Class E airspace at Grand Marais, MN. Additional controlled airspace is necessary to accommodate new Standard Instrument Approach Procedures at Grand Marais/Cook County Airport. The FAA is taking this action to enhance the safety and management of Instrument Flight Rules (IFR) operations at the airport.
Proposed Amendment of Class D Airspace; Denton, TX
This action proposes to amend Class D airspace at Denton, TX. Additional controlled airspace is necessary to accommodate new Standard Instrument Approach Procedures at Denton Municipal Airport. The FAA is taking this action to enhance the safety and management of Instrument Flight Rules (IFR) operations at the airport.
Airworthiness Directives; British Aerospace Regional Aircraft Model HP.137 Jetstream Mk.1, Jetstream Series 200, Jetstream Series 3101, and Jetstream Model 3201 Airplanes
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. The MCAI describes the unsafe condition as:
Airworthiness Directives; Bombardier, Inc. 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) issued by an airworthiness authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Airworthiness Directives; The Boeing Company Model 737-300, -400, and -500 Series Airplanes
We are adopting a new airworthiness directive (AD) for the products listed above. This emergency AD was sent previously to all known U.S. owners and operators of these airplanes. This AD requires repetitive external eddy current inspections of the lap joints at stringers S-4R and S-4L, along the entire length from body station (BS) 360 to BS 908. If a crack indication is found, the AD requires either confirming the crack by doing internal eddy current inspections, or repairing the crack. As an alternative to the external eddy current inspections, the AD provides for internal eddy current and detailed inspections for cracks in the lower skin at the lower row of fasteners at stringers S-4L and S-4R. This AD was prompted by a report indicating that a Model 737-300 series airplane experienced a rapid decompression when the lap joint at stringer S-4L between BS 664 and BS 727 cracked and opened up due to cracking in the lower skin at the lower row of fasteners. We are issuing this AD to detect and correct such cracking, which could result in an uncontrolled decompression of the airplane.
Airworthiness Directives; Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Model 382, 382B, 382E, 382F, and 382G Airplanes
We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires repetitive inspections for any damage of the lower surface of the center wing box, and corrective actions if necessary. This AD was prompted by reports of fatigue cracks of the lower surface of the center wing box. We are issuing this AD to detect and correct such cracks, which could result in the structural failure of the wings.
Airworthiness Directives; Eurocopter France Model AS350B, B1, B2, B3, BA, and EC130 B4 Helicopters
We are adopting a new airworthiness directive (AD) for the specified Eurocopter France (ECF) helicopters. This AD results from a mandatory continuing airworthiness information (MCAI) AD issued by the aviation authority of the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community. The superseding MCAI AD states that several engine flameouts have involved failure of the 41-tooth pinion in the engine accessory gearbox. Each affected helicopter had a starter-generator manufactured by one company. Investigation revealed the torque damping system of the starter-generator was inoperative due to incorrect adjustment that caused bending stresses on the 41-tooth pinion. Failure of the pinion causes the engine fuel pump to stop operating, resulting in an engine flameout. The EASA AD requires a new adjustment procedure to optimize the performance of the specified starter-generator damping assembly. This AD is intended to prevent failure of a pinion and a fuel pump, engine flameout, and subsequent loss of control of the helicopter.
