There could be several reasons. The hydraulic pump shuttle valve is sticking or some other issue in the pump, or the pressure switch is getting weak and shutting off the hydraulic pump before pressure is built up in the system. The gear will go all the way up even with as little as 800-900 psi even though the switch is a 1,400 psi switch, it never turns off at that pressure. It usually open the circuit at 1,000 psi or maybe 1,100 psi. It can also be the Hoof valve not closing all the way or the O-rings in the Hoof valve are worn out. It may also be an improperly adjusted cam in the emergency extension system. Those are a few problems that may prevent the gear from going all the way up or staying up. The Piper system is a real pain in the neck.

Thanks so much! I failed this part on my practical exam for Airframe!

buddy used to say, "Good'n tite, like a German virgin"

Im watching this in 2024. Im a commercial rated pilot with instrument rating (nearly 300 hours) and an owner of an archer II. Its insane that no CFI ever taught me this although nearly all of my flight hours are in my airplane. I was doing a preflight check with a friend of mine who is hesitant to fly in a small plane and that was going to be his first time. I was being reassuring and showed him how vigorous and thorough our preflight and safety procedures are. I encouraged him to move the elevator and he (thankfully) misunderstood me and moved the elevator like you did in the video instead of rotating it around its pivotal point - and I heard this rattling noise. I called my A&P and asked him if thats normal and he said “No. don’t fly the plane until I see it.” Next morning he checked it and said he’s glad I called him and didn’t fly the plane. He said the elevator would have eventually gave up, no one can say when or how many flights later exactly but judging by the movement range it doesn’t have much left. In other words I was saved by coincidence and by my friend’s incorrect execution of my instruction. Plane is now grounded and scheduled to have full elevator assembly service soon. My A&P friend thinks it’s going to be a labor intensive work and will be costly. I will update this comment when we find out what exactly is going on.

Mine did that before I lubed it with some fuel lube. After I lubed it immediately worked smoothly.

It's insane that this isn't taught by most instructors. Thank you!

Great information!

Excellent!

Was looking at videos for motorcycle lock wiring techniques and this popped up. Couple of interesting ideas here thanks. Also learned that you can get lock wire pliers that twist both ways, very cool. I might grab a pair, if they're not silly money.

I’ve listened to so many of your podcasts. Great to see you!

Much like a car/truck/suv

Beautifully done

Hello, Did this faulty pressure switch cause the breaker to pop by chance?

The time you talking dumb shit here you could already explain this little thing. There are tons of vids out about this. Just check someone else.

What type of Krytox do you use?

I've wondered about that to. I have an 0-470, wash down and blow dry can't find a thing on ground run. (and how long you going to run on the ground, cowling off) . A very 'nuisance' leak. After 3 flights you'll see a 'run' coming down the exhaust pipe the next morning on a hgr visit. (BTW, all tube seal were replaced, but looking afterwards on would think it's the seals) Cowled up air flow does crazy things.

A few years ago, I had an oil leak in my little Beech Sierra. Everything inside the cowling and the belly of the aircraft were covered with oil. Other than the mess, it didn't seem to be bad because oil consumption hadn't changed noticeably. The shop couldn't find the leak -- mostly because of the mess. I took my pressure washer to the airport and cleaned up the airplane. Then , with the cowling off and my mechanic watching, I started up the engine. Only then could he find the leak. Yup, the oil filter -- a loose fitting. The airplane has been spotless clean ever since.

very good

hi, also you need move to forward and after, because you can have lateral play by inside damages. we discovered an internal damage in one upper stringer and when you move to forward the last portion of fuselaje colapse.

Another cause of a stiff fuel primer can be a partially clogged primer nozzle at the cylinder. If the stiffness goes away when you remove the fuel line from the cylinder nozzle, then it is a clogged nozzle. Obviously more expensive to replace than two O-rings, but try that before disassembling the fuel primer valve.

Easily the best lock wire video I’ve seen. Great explanation through out. Thank you!

Nope, because idiots will try to fix theirs on a airplane..instead of replacing!

You are going to charge....f that

Yes

Dean, what lubricant do you recommend?

Yes!!

Very nice thanks

Thanks for the info!!

Hello Dean, I’m a student pilot who started flying 3 weeks ago and one of the things that my flight instructor kept telling me was the 2 clicks to the left and then one to the right. I haven’t asked him why not start with the left one first and the the two clicks to the left but your video explained this small but important detail. Thanks a lot 👊🏼

So..if.your showing aircraft owner how to service there landing gear..aren't you showing them how to break the law...so items the owner can /allowed to do, however, landing gear isn't one. Be careful folks. That log book entry "COULD " come back and bite cha..this coming from an A&P

Thanks, Dean, this helped me during an owner-assisted annual this year, replacing some old SCAT-12 that had holes in it. Good luck in your new PILOTING adventures!

All of this is nice... but once you determine that the charging system is NOT putting out the correct amount, how about showing how to determine if it is the voltage regulator, the overcharge relay, or the alternator itself. THAT would be helpful.

hello dean, show us how to connect the external hidraulic pump? thanks

Great tip, Dean! I always tried to have the wire under the hose clamp - never thought of pushing it back in. Your method sure seems much easier.

I just checked mine and there was slight play in it. Going to have it looked at before I fly again. Thank you

thanks

Dean, how did you solve this issue? That ticking noise at the end is due to the pressure switch? Best regards!

Thanks Dean. This helped my students in Aviation School.

Great video. Thank you!

Thanks for the video! 2 of the 3 Cherokees at my school have a noticeable amount of play… is there any information in the manual that has a set limit to allowable movement? I feel the school should have it repaired but want to show them that it is in fact not allowable…

Dean, went to look at your UA-cam channel and the Home page reports there isn’t any content! When looking at the Video page, it’s clear you have many...! Could someone have Hacked your UA-cam Channel Home page!

"2 little 1/4" bolts" they're NAS1104-17 bolts with a (minimum) tensile strength of 160,000 psi (each) and secured from falling out with a locknut. Don't believe they're just going to snap off or the nut is just going to fall off. There's hardly tension on the bolts aside from the 70-90in lb torque when the nuts are first put on. A common mistake that people have is to periodically check the torque which only serves to stretch the bolt and ruins things. Lube the hinge bolts with MIL-L-7870 every 100 hours. LPS 1,2,3 don't meet the mil spec. This comes from the maintenance manual which you can check for yourself.

One of the quickest subscriptions I’ve done ✅ awesome video! Thank you 🙏

You just made my SCAT install finally work. Liked and subbed. And thank you 🙏

Your the only one who’s interested in all these people, the rest of us could care a less. I thought this was going to show all the unique experimental aircraft. Your remark about the safety wire on the filter was really lacking in info, if you tighten it the way it’s done by most mechanics it will cut into the can of you don’t put RTV on the corner because of the pulsing of the oil pump.

That’s Wipaire’s Boss 182. It’s a 182 not a 206. They’re unbelievably awesome and one of the most complete, proficient and capable aircraft available! Just so cool! I love the paint as well!

Wow that’s a gorgeous TBM! Great Video and Podcast! Missed the show this year but seeing it through everyone’s videos this year! Thanks for sharing it!

This also applies to the Beech Musketeer models. They have a stabilator

pelska brought me here. very nice video and informative!

change the title...waste of time
