Applicable to: ALL
The procedure is intended for use when the nose or main landing gear fail to extend and/or lock
down following the application of the L/G GRVTY EXTN procedure.
It is preferable to use any available landing gear, rather than carry out a belly landing.
Under these circumstances, a hard surface runway landing is recommended.
Full advantage should be taken of any foam, spread on the runway.
PREPARATION
CABIN CREW......................................................................................................................NOTIFY
Notify the cabin crew of the nature of the emergency encountered and state intentions. Specify
the amount of available preparation time.
ATC....................................................................................................................................NOTIFY
Notify ATC of the nature of the emergency and state intentions.
Consider fuel reduction to a safe minimum. This reduces VREF and, consequently, the load
factor at impact and the energy to be dissipated.
GALLEY...................................................................................................................................OFF
If NOSE L/G abnormal:
CG location (if possible)......................................................................................................AFT
10 passengers from front to rear ‐ moves the CG roughly 4 % aft
‐ 10 passengers from mid to rear moves the CG roughly 2.5 aft.
If one MAIN L/G abnormal:
FUEL IMBALANCE................................................................................................. CONSIDER
Open the fuel X-FEED valve and switch off the pumps on the side with landing gear normally
extended.
OXYGEN CREW SUPPLY........................................................................................................OFF
SIGNS........................................................................................................................................ON
CABIN and COCKPIT..................................................................................................... PREPARE
Secure loose equipment, prepare survival equipment, and lock belts and shoulder harnesses.
