1. A previous post said it was at FL320 when it turned back.
2. Wing gear alternate extension.
3. Bounced / firm landing.
As said earlier all signs of a system 4 hydraulic failure.
1. Ops/Eng says come home.
2. Alternate extend wing gear & outboard flaps unfortunately right side wing gear gets fouled on the door.
3. Firm due to no R/H outboard elevator leaving approx 3/4 pitch authority. Bounce due to speed brake not armed as per the QRH due to no deployment of the ground spoilers (sys #4) on touch down which would cause a pitch up if they were armed due to remaining spoilers (sys 2&3).
Manual braking using system 1 for the rollout (antiskid-yes, autobrake - no)
The leading edge retracts on selection of reverse thrust completely normal. They were extended for the approach.
