Probable Cause: Insufficient lubrication of the engine’s internal components, which resulted in a total loss of engine power.

Post-Maintenance Flight Proves Fatal for Sport Pilot
Probable Cause: The pilot’s failure to maintain control of the airplane during the takeoff and his exceedance of the airplane’s critical angle of attack, which resulted in an aerodynamic stall and spin at low altitude. Contributing to the accident was the pilot’s lack of experience in the accident airplane make and model.
New Owner Mistake: Fuel Gauge Confusion Causes Fuel Exhaustion
A new Acro II owner’s misunderstanding of a fuel sight gauge led to a total engine failure. Learn why “assumed” burn rates are no match for system familiarity.
Pilot Attempts Takeoff With Flight Control Lock Still in Place
Probable Cause: The pilot’s inadequate preflight inspection, which resulted in an attempted departure with the flight control lock device installed, and subsequent nose landing gear collapse.
Vapor Lock and DIY Mods Lead to Crash of Modified Tri-Pacer
Probable Cause: A loss of engine power during initial climb due to fuel vapor lock. Contributing to the accident was the incorrect installation of the ancillary fuel supply system components.
Incorrect Carburetor Setting Leads to Loss of Engine Power on Takeoff
Probable Cause: The pilot’s adjustment of the carburetor to an incorrect setting, which resulted in partial loss of engine power during takeoff.
New Investigative Data Added to NTSB Aviation Accident Dashboard
The NTSB has updated its Civil Aviation Accident Dashboard to include investigative findings, offering deeper insight into what causes aviation accidents. This enhancement replaces the standalone General Aviation Dashboard, providing a streamlined, searchable resource for analyzing U.S. aviation safety trends.
Control Confusion Leads to Runway Excursion
Probable Cause: The commercial pilot’s failure to maintain directional control of the airplane during takeoff. Contributing was the student pilot’s application of brakes during the takeoff roll and the failure of both pilots to maintain a positive transfer of controls.
Human Factors: Know Thy Airplane
What can we learn from an accident that happened while taking kids up for their first flights by a pilot who didn’t have full knowledge of the airplane’s systems and a mechanic who missed a clogged fuel line?
