Don't think it is the RPB repair but am drawn to that skydrol which might be irrelevant. Still looking for answers as to whether it would need top up and whether that would be recorded in any kind of tech log. What are the consequences of Skydrol leak and where would it go- where would messy top ups go if they are needed. Still waiting for an engineer to tell me "there are no consequences worth note".
Hydraulic uplifts are recorded in the Tech log during normal line operations. The operator should have a process in place to monitor this. If regular uplifts are necessary a leak will be obvious. Manufacturers give limits in the AMM of what constitutes a seep, drip, running leak etc. But of course some operators will bend the rules.....
The worst thing about skydrol is it stings like buggery.
