    Parachuters Perish in Skydiving Training Tragedy

    What: Padobranski klub Banja Luka Cessna 182P Skylane
    Where: Zaluzani Airport, Bosnia
    When: May 20, 2012
    Who: 5 aboard
    Why: A pilot, a skydiving instructor and three parachutists went up for a parachuting lesson. The plane they were in crashed right after takeoff. Those aboard the flight were Nemanja Goronja, Alen Crnalic, Stefan Karanovic, Nikola Stevic and Srdan Kosic.

    Witnesses attempted to use fire extinguishers, but apparently a number of them failed to operate correctly.

    Among the five victims was an eighteen year old parachutist who was aboard for his first jump. The tragic wreck occurred in front of horrified onlookers there to witness the skydiving. Firefighters, ambulance crews, and Gojko Vasic, the RS Police Director Nedeljko Lubura from Banja Luka PSC were on the scene. The parachutists were members of the Club Banjaluka.

    The accident is under investigation.

    NTSB ANNOUNCES Lithium Ion Batteries in Transportation FORUM

    Today the National Transportation Safety Board announced that its upcoming forum, “Lithium Ion Batteries in Transportation,” will be held on April 11-12. The NTSB also released a preliminary agenda for the event.

    The forum will focus on three areas:

    • 1) the design, development and performance of lithium ion batteries;
    • 2) regulations and standards related to manufacturing, use and transport of the batteries; and
    • 3) the application and safety aspects of lithium battery technology in various transportation modes.

    Agenda

    Thursday, April 11 (9:00 a.m. – 4:30 p.m.)

    Panel 1: Design, Development, and Use of Lithium Ion Battery Technology

    Objective: This panel will discuss the design, development, and performance of lithium ion batteries. The design and development discussion will focus on battery configurations; advantages and disadvantages based on chemistry, power stability, and energy density; physical and electrical protective devices; manufacturing procedures and best practices; and quality assurance. The battery performance discussion will explore failure modes and other performance issues. Discussions will also include the range of lithium ion battery manufacturing processes.

    Panel 2: Regulations & Standards for Lithium Ion Batteries

    Objective: This panel will provide an overview and update of domestic and international regulatory requirements and standards associated with manufacturing, consumer and industry use, and transportation of lithium ion battery cargo. Topics will also include current and future lithium ion battery safety challenges for regulatory agencies and standard setting organizations.

    Friday, April 12 (9:00 a.m. – 12:30 p.m.)

    Panel 3: Lithium Ion Battery Applications & Safety in Transportation

    Objective: This panel will discuss the application and safety aspects of lithium battery technology in various transportation modes. The integration of the technology into existing designs will be explored including design standards, advantages and risks associated with use, reliability and failure; and what future use is planned. The panel will also discuss safety management considerations and strategies for first responders.

    Will Boeing Switch to Electrical Inquiry?


    Here’s what is bothering me:

    It’s no secret how planes are tested before they are released, to the very extreme so how did this electrical problem issue by the testing? Is my favorite plane manufacturer taking short cuts in quality control?

    The Japan Boeing 787 Dreamliner was delivered on Dec. 20 and had only flown 169 flight hours and 22 flights when one of its two lithium ion batteries caught fire.

    Is the investigation going to turn from the battery to the problem referenced by the whistleblower?

    Battery found not at fault by Safety Investigators in JAPAN

    But is GS Yuasa really off the hook?

    Battery questions:

    • If the battery was too hot, why didn’t it burn up on hours 1-169?
    • If the battery failed, what caused it to catch fire on the 22nd flight? Why that flight?
    • If the battery (which is a backup system replacing post flight hydraulics) only operates on the ground and is only engaged on the ground, why are flights grounded? If the battery is only at use on the ground, is it an actual flight risk or a post-flight risk?
    • Is the solution going to be simply going to the other type of lithium ion battery (nickel metal-hydride technology), or will components or the whole system be replaced?
    • Was this simply a GS Yuasa quality control failure, a batch of bad batteries manufactured by GS Yuasa of Japan in September 2012?

    The entire 787 fleet is grounded. Replacing the battery system might be a “quick” fix but certification could last a year.

    A large format battery can generate heat faster than it dissipates.

    Is venting the battery and monitoring the vents a viable temporary solution that could keep the planes in the air until a system alternative has been certified within the year?

    The current batteries are “prone to spontaneous combustion due to ‘organic electrolyte which makes it volatile and flammable.'”
