Nose Gear/Doors
When the landing gear handle is lowered and both main gear doors open, an
electrical signal commands the nose gear hydraulic actuator to lower the nose
gear. When the gear extends it allows the spring-loaded nose gear doors to open.
A spring-strut braces the nose gear folding strut in the over-centre position to lock
the nose gear down.
Upon retraction, rollers on each side of the nose gear strut pull the nose gear doors
up with the gear and hold them shut. The nose gear is locked in the up position by
an internal actuator lock.
Emergency Extension
The emergency extension handle is located on the lower left side of the instrument
panel in the front cockpit only, and is placarded EMER LDG GR.
The emergency hydraulic accumulator provides hydraulic pressure through
independent lines to the four gear actuators to extend the main gear doors and
landing gear. Electrical power is not required to use the emergency gear extension
system.
Actuate the emergency gear system by pushing the button on the EMER LDG GR
handle and pulling the EMER LDG GR handle out. The main gear doors open and all
three gear extend regardless of the landing gear handle position.
Once the gear is down and locked, the inboard main gear doors remain open.
Cockpit indications will be a red light in the gear handle, a green nose gear
indicator, and red and green indicators for each main gear. The landing gear cannot
be retracted after being extended with the emergency system.
