Safety recommendation
The National Transportation Safety Board has directed Boeing to develop new preflight procedures for specific aircraft models to ensure flight crews can verify elevator status before takeoff.
The National Transportation Safety Board (NTSB) has issued safety recommendation A-19-002, identified by reference number DCA17FA076, addressed directly to The Boeing Company. This official directive urges the manufacturer to develop new preflight procedures or implement other appropriate mitigations for Boeing DC-9/MD-80 series and 717 model airplanes. The primary objective of these measures is to enable a flight crew to verify before takeoff that the elevators are not jammed, thereby enhancing operational safety during critical phases of flight.
