Aviation Recommendations

The Pipeline and Hazardous Materials Safety Administration is required by law to respond to safety recommendations issued by the National Transportation Safety Board (NTSB), an independent federal agency charged by Congress with investigating significant incidents that involve hazardous materials. Recommendations usually address a specific issue uncovered during an investigation or study and specify how to correct the situation.

NTSB Classifications:

  • OAA - Open Acceptable Response
  • OAAR - Open Acceptable Alternate Response
  • OUA - Open Unacceptable Response
  • ORR - Open Response Received
  • OAR - Open Await Response

The items below are the currently open NTSB recommendations regarding aviation.
