Which risk increases when a retractable aircraft landing gear's actuators experience reduced hydraulic pressure nearing touchdown?

A)Uncommanded gear collapse occurs
B)Engine stall probability increases
C)Fuselage skin cold cracks form
D)Elevator flutter instability begins

💡 Explanation

Uncommanded gear collapse increases risk because insufficient pressure impairs the down-lock mechanism, a physical latching system, needed to secure the gear. Therefore the gear can buckle under load rather than sustaining operational pressures at ground contact.
