Section 3 – Emergency procedures
GEAR PUMP FAILURE
2.7. GEAR PUMP FAILURE
The GEAR PUMP ON caution light turns ON when the landing gear hydraulic
pump is electrically supplied.
After the landing gear retraction, if the red TRANS light turns OFF and the
GEAR PUMP ON caution stays turned ON, this could indicate a gear pump relay
failure to ON.
1. Continue the mission monitoring the caution light.
2. Landing gear is not locked in UP position
The electrical gear pump, continuously supplied, causes a current
absorption which does not affect the mission unless this failure is
coupled with the overall electrical failure. In this case, the residual
battery endurance may be consistently lower than 30 minutes.
