Safety recommendation
The National Transportation Safety Board has directed Boeing to update maintenance manuals for specific aircraft models to lower ground gust criteria for elevator checks.
The National Transportation Safety Board (NTSB) has issued Safety Recommendation A-19-003, designated as DCA17FA076, addressed directly to The Boeing Company. This directive mandates that Boeing revise the Aircraft Operating Manual and the Aircraft Maintenance Manual for Boeing DC-9/MD-80 series and 717 model airplanes. These revisions are required until the actions outlined in Safety Recommendations A-19-1 and A-19-2 are fully completed. The specific purpose of these manual updates is to lower the ground gust criteria that trigger physical inspections and operational checks of the elevators by maintenance personnel. This measure ensures that structural integrity assessments occur under more conservative wind conditions, thereby enhancing safety protocols for these aircraft types.
