As far as your problem with the aft canopy actuator problem, I have two things for you that you may not be aware of. First: There is no air pressure to the shuttle valve and the bottom of the actuator when the selector valve is in the closed position. That is why the leak stops when you close the canopy and the selector valve vents the air from the bottom.. The raise function works by the upper side of the piston having less surface area, but is always pressurized. When air is applied to the lower end the canopy goes up because the larger surface area of the bottom creates more force to make it extend. Second: The shuttle valve is attached to the actuator by a "fluid passage bolt". It is hollow and allows air to pass from two holes in the sides allowing the air from the shuttle valve to pass to the bottom of the actuator. The fluid passage bolt has two o-rings on it to seal the head of the bolt and the valve to the bottom of the actuator. This is where it always leaks. It is very easy to rip the o-rings during installation. The best method is to lubricate both o-rings with some pneumatic grease when you install the valve to make the o-rings slip a little instead of catching and ripping. Also seat the bolt fully in the shuttle valve and don't let it slip down during installation or the threads on the bolt will tear the o-ring that sits between the valve and the actuator. "By the book" the shuttle valve is meant to be installed with the actuator removed, although this is never really done in the 'real world" because the aft canopy actuator is unbelievably hard to remove. If you guys have a canopy maintenance strut, I can give you another shortcut.

You are correct about no rat on the e models. In that space was rhaw boxes that i had to get to. . It was known as panel 185L and had about 150 screws to get it off. Thanks for the great videos.

Phantoms have some very very sharp edges. I always got some cuts working on them & a lot of other guys did also. Make super triple sure all is right before taking that bad boy up. They glide like a rock. Love to be at that airshow but no way I can do. These aircraft are awesome.

I enjoyed the bit about the RAT. I was a Skyhawk guy, but we had a Phantom squadron next to us. Always saw the RAT getting checked on the Phantoms, but didn't know anything about it. I'm surprised that it's pneumatic, and even more surprised at how fast those doors close! Holy cow! It makes me even happier to have worked on the simple and safe RATs on the Skyhawks! Thanks for the video!

For all you old guys. The "C" and early "D" models had hydraulics in the rat. The end of 67 they came out with a TCTO to hook all the hyd systems together with just enough pressure to work esp the PC's.

it's a good phantom plane, how old is it and it's normal that its systems slowly fail when there are no more spare parts for it. Your video is commendable, congratulations this option should be added to dcs for pilots to fly their own planes like you are doing on this, it would teach them to appreciate every module in dcs they have and to treat it like real pilots

Nice job explaining the HIPAC, you don't know how many N2 bottles we went through before we got that thing LOL!! I will never forget the day the rat tried to eat Al, that was scary, and there was a race to the cockpit to get it open again. Like a true crew chief though he stayed and made sure the flight went well. It was a July 4th night flight we did and was quite a day.

What does that mean: "the rat tries to eat AL?" Like someone's hand almost got caught in the fast closing doors?

@flyboy126 2 ай бұрын

@@PaulLoveless-Cincinnati Yes we had a nightflight with an instantaneous time window we had to hit. The rat developed a leak that was too big to fly with so we had no choice but to repair it. We disconnected one of the doors and the pneumatic system had leaked down to somewhere below 1500 psi. While Al was working on it he accidentally overcentered the arm of the door that was still connected which triggered it to close. The rat came down pinning his arm and then the connected door tried to close on top of that. He was hurt pretty bad as it was, but if we had a full 3000 psi on the system I don't even want to think about how bad it would have been.

This is why I'm constantly amazed that the hostile country Iran, embargoed as best we can from getting F-4 parts, can still fly those things. I have heard a lot of them are indeed grounded (lack of parts, age, LEAKS). Yet, some fly. Iranian mechanics are pretty good.

With the Phantom being almost entirely electro-mechanical, I'd imagine she'd be fairly adaptable. As I understand it, they fly them somewhat regularly.
