questions in #208
arc-en-ciel,
I will try to answer your questions:
ad.1: I flew the B767 for many years and experienced 2 cases of leak from the CTR HYD SYST - in both cases the leak stopped completely after performing the malfunction checklist, which requires that all 3 HYD pumps are switched off. So I do not think that your concern is relevant in case of the B767.
ad.2: At this point nobody knows, but it should not be too difficult to find out. A post on another pilot website claims that the circuit breaker for the alternate extension system had popped and could not be reset.
