If the skydrol leak was long term would this need topping up- where would you top it up and where would top up spillage go?
(The engineer on our little aeroplanes has put a notice in the hangar that says "do not oil the battery").
And why wasn't it fixed? I haven't seen this on any Airbus 3xx that I have come across in the UK or India so it isn't a common thing is it?
