A320 Gravity Gear Extension...Can you retract?

[virgin camel]

So..

You lower the U/C using gravity gear extension....

I believe you can retract the U/C in case of a Ga Around in all circumstances apart from:

1. ALL Dual Hydraulic failures (QRH)
2. ADR 1+3 Fault (FCOM 3)

Any others???

Negative.
The ONLY case when you CAN recycle the free-fall L/G system is during training flight when the green Hydraulic is available...to recover the nose wheel steering (at least for the models using the green hydraulic for the nose wheel steering,as gravity extension cut the green HYD supply to the gear.), and to close the landing gear's doors.
Check QRH or FCOM3 abnormal procedure :" L/G gravity extension".
