I remembered something when i saw this forum and thought I would add it. I flew in a few heli's in the Marines, and every ride scared me, But I remember one flight in a CH-46 Sea Knight in which there was hydraulic fluid leaking close to the aft rotor. I told the crew chief and he told me not to worry." If the leak stops, make sure you let me know!" To this day im not sure if he was messing with me or not. These heli's were over 30 years old.

Probably not. Usually means that it is out of oil.

rc12 -> RE: Marine Helicopters (1/16/2004 10:28:17 PM)
Why ?

He meant it jokingly im pretty sure, Those frogs leak hydraulic fluid regularly and they add it sometimes in flight I was told by another crew chief.

its true ... if it aint leaking its not flying!..and i was a rappell master in the marines and if been in the huey,the ch46 and the ch 53... and there was aways a bag of ''kitty litter'' right by the crew cheif

In the old Charlie model CH-47's manual (big brother to the Ch-46) there was a section that stated allowable drips per minute in the hydraulic system. While the Chinook had taken care of the leaks in the new Delta configuration, I'm not so sure that the Sea Knight had those issues reengineered. I believe the late 70's was when the last Sea Knight was built and there haven't been any more production helicopters made. We operate with a 3,000 psi hydraulic system. So now if you see a leak, its monitored to verify if it is seeping or leaking. Leaks are bad, very very bad. As far as adding fluid inflight, we did it as Chinook guys just to mess with the passengers. I'm not sure if the Sea Knight crews are the same or not but if its an operational necessity, I'm sure they still get a kick out of screwing with the passengersw.

who needs hydraulic pressure anyways? [:D]
