  • Aircraft Accident Report: American Airlines, Inc., Mcdonnell Douglas
    Explosive decompression, American Airlines, Inc., McDonnell Douglas DC-10-10, N103AA, Near Windsor, Ontario, Canada, June 12, 1972 Micro-summary: On climb, this McDonnell Douglas DC-10-10 experienced an opening of a cargo door, explosive decompression, and a main cabin floor collapse, disrupting the flight control system. Event Date: 1972-06-12 at 1925 EST Investigative Body: National Transportation Safety Board (NTSB), USA Investigative Body's Web Site: http://www.ntsb.gov/ Cautions: 1. Accident reports can be and sometimes are revised. Be sure to consult the investigative agency for the latest version before basing anything significant on content (e.g., thesis, research, etc). 2. Readers are advised that each report is a glimpse of events at specific points in time. While broad themes permeate the causal events leading up to crashes, and we can learn from those, the specific regulatory and technological environments can and do change. Your company's flight operations manual is the final authority as to the safe operation of your aircraft! 3. Reports may or may not represent reality. Many many non-scientific factors go into an investigation, including the magnitude of the event, the experience of the investigator, the political climate, relationship with the regulatory authority, technological and recovery capabilities, etc. It is recommended that the reader review all reports analytically. Even a "bad" report can be a very useful launching point for learning. 4. Contact us before reproducing or redistributing a report from this anthology. Individual countries have very differing views on copyright! We can advise you on the steps to follow.

On arrival it was parked at Gate H30 and later towed to its departureGate H5 at 1945 hrs. At 2207 hrs the flight was cleared for enginestart and push-back and it commenced taxiing to Runway 27R nineminutes later. The taxi route to the runway took the aircraftdirectly onto the outer taxiway and then onto Runway 23 whichit backtracked. The total time spent taxiing was approximatelynine minutes. The flight destination was São Paulo, Brazil and, due tothe length of the flight, two flight deck crews were on board. The crew had arrived two days previously and, for the departure,consisted of a Captain in the left hand seat, who was undertakinga conversion from a different aircraft type, and a training Captainin the right hand seat who was the designated aircraft commander.

  • Testimony of Ms. Dana Schulze Acting Director, Office of Aviation Safety
    Testimony of Ms. Dana Schulze Acting Director, Office of Aviation Safety National Transportation Safety Board Before the Subcommittee on Aviation Committee on Transportation and Infrastructure United States House of Representatives — On — Status of Aviation Safety — Washington, DC • July 17, 2019 An Independent Federal Agency Good morning, Chairman Larsen, Ranking Member Graves, and Members of the Subcommittee. Thank you for inviting the National Transportation Safety Board (NTSB) to testify before you today. I am the Acting Director of the Office of Aviation Safety within the NTSB. The NTSB is an independent federal agency charged by Congress with investigating every civil aviation accident in the United States and significant accidents in other modes of transportation – highway, rail, marine, and pipeline. We determine the probable cause of the accidents we investigate, and we issue safety recommendations aimed at preventing future accidents. In addition, we conduct special transportation safety studies and special investigations and coordinate the resources of the federal government and other organizations to assist victims and their family members who have been impacted by major transportation disasters. The NTSB is not a regulatory agency – we do not promulgate operating standards nor do we certificate organizations and individuals. The goal of our work is to foster safety improvements, through formal and informal safety recommendations, for the traveling public. We investigate all civil domestic air carrier, commuter, and air taxi accidents; general aviation accidents; and certain public-use aircraft accidents, amounting to approximately 1,400 investigations of accidents and incidents annually. We also participate in investigations of airline accidents and incidents in foreign countries that involve US carriers, US-manufactured or - designed equipment, or US-registered aircraft.

  • Flight Data Recorder Handbook for Aviation Accident Investigations
    National Transportation Safety Board Vehicle Recorder Division Flight Data Recorder Handbook for Aviation Accident Investigations Office of Research and Engineering Office of Aviation Safety Washington, DC 20594 A Reference for Safety Board Staff ii FOREWORD This handbook provides general information to assist the investigator-in-charge, group chairmen, and other Safety Board staff who may encounter a flight data recorder during the course of an aviation accident investigation. It is intended to provide guidance on the procedures, laws and standard practice surrounding the flight data recorder and its recorded information during the course of an investigation. The Vehicle Recorder Division will be responsible for keeping this handbook updated. The handbook's printing date will be indicated in the upper left corner of each page. While the intent of the handbook is to provide guidance for handling a flight data recorder and its recorded information, the handbook may not cover all situations, and any questions or concerns may be directed to the Chief of the Vehicle Recorder Division for immediate assistance. This handbook is an NTSB staff product and is intended to provide information and guidance to NTSB employees who are involved in the flight data recorder portion of an aviation accident investigation. This handbook has not been adopted by the NTSB Board Members, is not regulatory in nature, is not a binding statement of policy, and is not all- inclusive. The recommended procedures are not intended to become obligations of the NTSB or to create any rights in any of the parties to an NTSB investigation. Deviation from the guidance offered in this handbook will at times be necessary to meet the specific needs of an investigation.

To allow readers to also see these detailed changes, this document has been created. The same format as for publication of Notices of Proposed Amendments (NPAs) has been used to show the changes: (a) deleted text is struck through; (b) new or amended text is highlighted in blue; (c) an ellipsis ‘[…]’ indicates that the remaining text is unchanged.
