Core stage cutoff was intended for T + 296 seconds, but the premature propellant depletion caused thrust termination to occur one second earlier when a sensor detected overspeed of the empty RP-1 turbopump.

The plane showed no sign of trouble until its single engine unexpectedly went into an " overspeed, " a condition when the engine exceeds its design power, and effectively self-destructed, Smith said.
43.
The co-pilot's ASI read and decreasing, yet the aircraft started to give multiple contradictory warnings that it was flying too fast, including rudder ratio, Mach airspeed, and overspeed lights and sounds.
44.
While broadly similar to the model used on the Mirage III, the Atar engine had a greater airflow and an elevated overspeed limit from 8, 400 rpm to 8700 rpm for greater thrust during high altitude supersonic flight.
45.
The crew could not be expected to have been sufficiently knowledgeable about the aircraft's control system to understand the seriousness of the intermittent overspeed alarm, and there were no procedures or checklists available that covered this scenario.
46.
Blockage, damage, or inoperation of stall and angle of attack ( AOA ) probes can lead to unreliability of the stall warning, and cause the stick pusher, overspeed warning, autopilot, and yaw damper to malfunction.
47.
The governor also incorporates a separate overspeed protective mechanism that will immediately cut off the fuel supply to the cab in the event the prime mover exceeds a defined RPM . Not all of these inputs and outputs are necessarily electrical.
48.
In May 1959, propeller pitch-lock mechanisms, designed to arrest the pitch of the blades and prevent them from opening further when an overspeed is imminent, became mandatory on U . S . piston-engined transport aircraft.
49.
One problem that designers have had to overcome is " overspeed, " when the wind blows so hard that the turning blades can burn up a generator designed to function efficiently in wind speeds as low as 8 miles per hour.
50.
The'Overspeed Sensor System'pair of loops is located on the approach to the signal, and will trigger the train brakes if it approaches faster than the'set speed'when the signal is at " danger ".
