4B.7 FAILURES IN HYDRAULIC SYSTEM
4B.7.1 CONTINUOUS HYDRAULIC PUMP OPERATION
1.Landing gear indication lights . . . . . . . . . . . . check
2.Prepare for manual landing gear extension. Refer to Section 3.8.2 - MANUAL
EXTENSION OF THE LANDING GEAR.
NOTE
The landing gear might extend as the hydraulic system pressure decreases. Consider for higher aerodynamic drag, resulting in degraded flight performance, increased fuel consumption and decreased range.
Unscheduled maintenance action is required after landing.

Abnormal Operating
DA 42 NG AFM
Procedures
CAUTION
When switching the External Power Unit ON, the electrically driven hydraulic gear pump may activate itself for 5 to 20 seconds in order to restore the system pressure. Should the pump continue to operate continuously or periodically, terminate flight. There is a malfunction in the landing gear system.
NOTE
When switching the External Power Unit ON, all electrical equipment, connected to the LH and RH main buses is powered.
17. G1000 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . wait until power-up completed. Press ENT on MFD to acknowledge.
NOTE
The engine instruments are only available on the MFD after item 17 has been completed.
