    Kotaite Lecture on the Future of Aviation Safety

    National Transportation Safety Board Chairman Deborah A. P. Hersman delivered the 8th Annual Assad Kotaite Lecture last evening at the International Civil Aviation Organization (ICAO) Headquarters in Montreal, Quebec, Canada. Hosted by the Montreal Branch of the Royal Aeronautical Society, the annual lecture is a tribute to Dr.Assad Kotaite, former Secretary General of ICAO and President of the Council of ICAO.

    Chairman Hersman’s talk, “Assuring Safety in Aviation’s Second Century,” highlighted the past, present, and future of accident investigation and addressed how accident investigation must adapt to play an even more pivotal rolein creating civil aviation’s safer and stronger future. Citing examples from recent accident investigations, Hersman said that it’s clear that future accident investigations will depend far more on data and cooperation than in the past.

    “While traditional tin-kicking will never go away, it is increasingly being joined by sophisticated data analysis,” Hersman said. “In this era of dynamic growth and greater complexity, data is more important than ever.”

    Hersman applauded the agreement reached last year at the 37th ICAO Assembly to foster data sharing through the creation of the Global Safety Information Exchange. This information can be vital to investigators as they seek to learn what really happened and determine what can be done to
    improve safety.

    “Data and cooperation is how the aviation community will maintain – and enhance – its strong safety record into the second century of powered flight,” Hersman said.

    NTSB Safety Recommendations A-11-1 through -6

    National Transportation Safety Board
    Washington, DC 20594
    February 1, 2011

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

    Require Cessna Aircraft Company and other manufacturers whose restraint system designs permit an occupant to use an inactive airbag restraint system not intended for use in his or her seat to modify their restraint system designs to eliminate that possibility, and require them to modify restraint systems in existing airplanes to eliminate the possibility of misuse.

    Revise the guidance and certification standards concerning restraint systems to recognize and prevent potential misuse scenarios, including those documented in this safety study.

    Modify the special conditions for the installation of inflatable restraints on general aviation airplanes (at Federal Register, vol. 73, no. 217 [November 7, 2008], p. 66163) to provide specific guidance to manufacturers as to how they should demonstrate that the protection is effective for occupants that range from the 5th percentile female to the 95th percentile male.

    Require the retrofitting of shoulder harnesses on all general aviation airplanes that are not currently equipped with such restraints in accordance with Advisory Circular (AC) 21-34, issued June 4, 1993.

    Evaluate the potential safety benefits and feasibility of requiring airbag-equipped aircraft to have the capability to capture and record, at a minimum, data concerning crash dynamics and airbag deployment criteria that can be reviewed after a crash to determine whether the system performed as designed.

    Develop a system to track individual aircraft information about aircraft safety equipment, such as restraint systems, airbags, aircraft parachutes, and other specific aircraft equipment, designed to improve crash outcomes.

    NTSB Directive Contradicts Boeing Statement

    On April 25, the NTSB released information about the April 1 Southwest Airlines Boeing 737-300 fuselage incident where the rupture in the fuselage caused depressurization and forced pilots to make an emergency landing in Yuma.

    From the release

    The NTSB Materials Laboratory work is actively conducting additional inspections and examinations in the following areas:

    1. Removal of rivets and examination of rivet hole dimensions, rivet dimensions, and rivet hole alignment between upper and lower skins.
    2. Detailed fractographic analysis of the skin fractures emanating from the rivet holes using optical and scanning electron microscopes.
    3. Fatigue striation analysis using a scanning electron microscope of specific skin fractures to determine the rate of crack propagation.
    4. Additional portions of the lap joints from the accident aircraft.

    Of 136 airplanes inspected worldwide four had crack indications at a single rivet and one plane was found to have crack indications at two rivets.

    In spite of these findings, Boeing Chief Executive Jim McNerney told Reuters“I think the initial data that I think we’re all seeing is suggesting a possible workmanship issue on an airplane, rather than a design issue across a fleet of airplanes.”

    If Boeing believes that the problem was workmanship on a single plane, then how did other planes reveal conditions precursing the same type of rupture incident as was incurred on Southwest Airlines Flight 812?

    NTSB MEETS TO CONSIDER SAFETY STUDY ON THE USE OF AIRBAGS IN GENERAL AVIATION AIRCRAFT

    National Transportation Safety Board
    Washington, DC 20594

    January 6, 2011

    The National Transportation Safety Board will hold a public
    Board meeting to consider a safety study on the
    effectiveness of airbags in general aviation (GA) aircraft.

    The NTSB initiated the safety study to 1) examine the
    effectiveness of airbags in mitigating occupant injury in a
    survivable GA accident, 2) identify any unintended
    consequences of airbag deployments, and 3) develop
    procedures to assist investigators in documenting airbag
    systems in future investigations.

    During the course of the study, investigators became aware
    of several potential issues that could compromise occupant
    safety associated with the use, adjustment and design of
    restraint systems. All of these findings will be presented
    to the five-Member Board for their consideration.

    The meeting will be held on Tuesday, January 11, at 9:30
    a.m., in its Board Room and Conference Center, 429 L’Enfant
    Plaza, S.W., Washington, D.C.

    A live and archived webcast of the proceedings will be
    available on the Board’s website at
    http://www.ntsb.gov/Events/Boardmeeting.htm. Technical
    support details are available under “Board Meetings.” To
    report any problems, please call 703-993-3100 and ask for
    Webcast Technical Support.

    A summary of the safety study, which will include its
    findings and safety recommendations, will appear on the
    website shortly after the conclusion of the meeting. The
    entire study will appear on the website several weeks later.
