    NTSB Recommendations

    National Transportation Safety Board
    Washington, DC 20594
    February 23, 2012

    The National Transportation Safety Board makes the following recommendations to the Federal Aviation Administration:

    Modify the design and test requirements for the attachment points of passenger service units to account for the higher localized loading that results from the relative motion of the attachment structure. (A-12-1)

    Require that the installation design for overhead bins and passenger service units (PSU) manufactured by Boeing and installed in Boeing 737NG series airplanes be modified so that the PSUs remain attached to the bins or are captured in a safe manner during survivable accidents. (A-12-2)

    Review the designs of manufacturers other than Boeing for overhead bins and passenger service units (PSU) to identify designs with deficiencies similar to those identified in Boeing’s design, and require those manufacturers, as necessary, to eliminate the potential for PSUs to separate from their attachments during survivable accidents. (A-12-3)

    Develop test criteria and performance measures for negative-g strap assemblies to better evaluate their real-world loading capability during accident sequences. (A-12-4)

    Once test criteria and performance measures are established as recommended in Safety Recommendation A-12-4, amend 14 Code of Federal Regulations Part 25, as appropriate, to include the newly developed test criteria and performance measures for negative-g strap assemblies. (A-12-5)

    Require that negative-g strap attachment brackets manufactured by Ipeco be retrofitted with stronger brackets. (A-12-6)

    ************************************************************

    The National Transportation Safety Board recommends that the Federal Aviation Administration:

    Require Boeing to develop a method to protect the elevator power control unit input arm assembly on 737-300 through -500 series airplanes from foreign object debris. (A-11-7)

    Once Boeing has developed a method to protect the elevator power control unit input arm assembly on 737-300 through -500 series airplanes from foreign object debris as requested in Safety Recommendation A-11-7, require operators to modify their airplanes with this method of protection. (A-11-8)

    Require Boeing to redesign the 737-300 through -500 series airplane elevator control system such that a single-point jam will not restrict the movement of the elevator control system and prevent continued safe flight and landing. (A-11-9)

    Once the 737-300 through -500 series airplane elevator control system is redesigned as requested in Safety Recommendation A-11-9, require operators to implement the new design. (A-11-10)

    Require Boeing to develop recovery strategies (for example, checklists, procedures, or memory items) for pilots of 737 airplanes that do not have a mechanical override feature for a jammed elevator in the event of a full control deflection of the elevator system and incorporate those strategies into pilot guidance. Within those recovery strategies, the consequences of removing all hydraulic power to the airplane as a response to any uncommanded control surface should be clarified. (A-11-11)

    Fourth Investigative Update on Boeing 787 Battery Fire


    NTSB Provides Fourth Investigative Update on Boeing 787 Battery Fire in Boston

    January 27, 2013
    WASHINGTON – The National Transportation Safety Board today released a fourth update on its investigation into the Jan. 7 fire aboard a Japan Airlines Boeing 787 at Logan International Airport in Boston. The fire occurred after the airplane had landed and no passengers or crew were onboard.

    The event airplane, JA829J was delivered to JAL on December 20, 2012. At the time of the battery fire, the aircraft had logged 169 flight hours with 22 cycles. The auxiliary power unit battery was manufactured by GS Yuasa in September 2012.

    NTSB investigators have continued disassembling the internal components of the APU battery in its Materials Laboratory in Washington, and disassembly of the last of eight cells has begun. Examinations of the cell elements with a scanning-electron microscope and energy-dispersive spectroscopy are ongoing.

    A cursory comparative exam has been conducted on the undamaged main battery. No obvious anomalies were found. More detailed examination will be conducted as the main battery undergoes a thorough tear down and test sequence series of non-destructive examinations.

    In addition to the activities at the NTSB lab, members of the investigative team continue working in Seattle and Japan and have completed work in Arizona. Their activities are detailed below.

    ARIZONA
    The airworthiness group completed testing of the APU start power unit at Securaplane in Tucson and the APU controller at UTC Aerospace Systems in Phoenix. Both units operated normally with no significant findings.

    SEATTLE
    Two additional NTSB investigators were sent to Seattle to take part in FAA’s comprehensive review. One of the investigators will focus on testing efforts associated with Boeing’s root cause corrective action efforts, which FAA is helping to lead. The other will take part in the FAA’s ongoing review of the battery and battery system special conditions compliance documentation.

    JAPAN
    The NTSB-led team completed component examination of the JAL APU battery monitoring unit at Kanto Aircraft Instrument Company, Ltd., in Fujisawa, Kanagawa, Japan. The team cleaned and examined both battery monitoring unit circuit boards, which were housed in the APU battery case. The circuit boards were damaged, which limited the information that could be obtained from tests, however the team found no significant discoveries.

    FAA: “Line Up and Wait” Training Now Available

    “Line Up and Wait” Training Now Available
    On Sept. 30, 2010, the familiar ATC instruction “taxi in position and hold” will become history. Instead, expect to hear “line up and wait” when ATC issues instruction for a pilot to taxi onto a departure runway and wait for takeoff clearance. Another procedure change that occurred on June 30, 2010, requires ATC to issue an explicit clearance to aircraft crossing any runway (active, inactive, and closed). To help pilots with these important procedure changes, FAA added an online training module to www.FAASafety.gov. The course is titled “Line Up and Wait: Taxi Authorization and Runway Clearance Guidance for Airmen,” and is listed in the Featured Courses portal on the FAASafety.gov home page.

    The course provides a good review of safe taxi operations, ATC procedures and phraseology, and pilot responsibilities. It also reviews best practices for avoiding runway incursions, such as knowing and understanding the meaning of the runway hold markings. Some three-fourths of runway incursions result from a failure to comply with this marking.

    Additional details on both procedure changes are available in the Aeronautical Informational Manual (AIM) and Pilot/Controller Glossary, located under the Air Traffic section of www.faa.gov. You can also reference more specific information on line up and wait with FAA Notice JO 7110.536.

    DOT Fines US Airways for Failure to Provide Wheelchair Assistance to Passengers with Disabilities

    WASHINGTON – The U.S. Department of Transportation (DOT) today fined US Airways $1.2 million for failing to provide adequate wheelchair assistance to passengers in Philadelphia and Charlotte, N.C. The fine is one of the largest ever assessed by DOT in a disability case.

    “All air travelers deserve to be treated equally and with respect, and this includes persons in wheelchairs and other passengers with disabilities,” said U.S. Transportation Secretary Anthony Foxx. “We will continue to make sure that airlines comply with our rules and treat their passengers fairly.”

    Under DOT’s rules implementing the Air Carrier Access Act, airlines are required to provide free, prompt wheelchair assistance upon request to passengers with disabilities. This includes helping passengers to move between gates and make connections to other flights.
    In one of its periodic reviews of airline compliance with DOT rules, the Department’s Aviation Enforcement Office found that US Airways committed a significant number of violations of the requirements for wheelchair assistance during 2011 and 2012 at Philadelphia International Airport and Charlotte Douglas International Airport. As part of its review, the Enforcement Office examined approximately 300 complaints filed by passengers with the airline and DOT relating to incidents at Philadelphia and Charlotte, which covered only a sample of complaints filed over two years against US Airways for the two airports. The airline’s use of a combination of electric carts and wheelchairs to carry passengers between gates required frequent transfers and led to long delays. Some passengers missed connections because of the delays or were left unattended for long periods of time.

    Of the $1.2 million fine, US Airways may use up to $500,000 for improvements in its service to passengers with disabilities that are beyond what DOT rules require. These include hiring managers to ensure the quality of the airline’s disability services in Philadelphia and Charlotte, creating a telephone line to assist these passengers, purchasing tablets and other equipment to monitor assistance requests, providing compensation to passengers with disability-related complaints, and programming the airline’s computers so that boarding passes identify passengers who request special services.
