Flex Seal was developed for boats with screen door bottoms. Apparently a big market since they advertise all the time. [youtube]https://youtu.be/httSHnNXN10[/youtube] Mike C.

You must live in a very different advertising market than me…

They are oleophilic and hydrophobic, so they can actually absorb oil from water and leave the water behind. Handy for situations where oil got into some water and you just want to skim it off the top. They’re often part of spill kits, but are great at cleaning up oily messes just about anywhere. I have some in my garage.

Glad Mark and Dylan were able to help. The week before I was taking my son back to Montgomery and had a mag fail. Diverted to Florence, SC. Due to the holiday weekend, I elected to fly home commercial and leave the plane. Thankfully the local FBO was able to get me a new mag and I flew back Saturday morning, paid the bill and flew home to Lawrence. Moral of the story is any of these things can break, and when they break far from home it’s scary. Thankfully there are good folks in aviation that usually will help.

I have some in my garage. Yep, I have the exact same roll as Mike listed. We used a much larger version when I had my drilling company. They were great when a major hydraulic leak would occur on one of my rigs. With 200 gallon hydraulic reservoirs, and a system running at 5,000psi, a leak was very messy!

Username Protected wrote: Do any of these planes using hydro pressure to operate systems provide any indication of reservoir level other than a low level switch ? Mine doesn't, all I get is a low level caution if the plunger reaches the microswitch. This is some amount before empty, but if I get there, then I've lost a lot of fluid and I should expect nothing will operate very soon. During the prior flight, I did not get any abnormal indications at all, and based on the fluid on the ground, most of it leaked out after we parked. You can see the switch on the plunger here: Attachment: hyd-reservoir-1.png Without hydraulics, I have lost landing gear, flaps, speedbrakes, and thrust reversers. Landing gear can be put down using the emergency system which releases uplocks and it free falls. A pressure bottle provides more assurance. If I saw the hydraulic low level come on, I would be tempted to put the landing gear down immediately and fly gear down to a nearby safe landing. By doing this, I don't take the chance the emergency system fails (it depends on cables to release the uplocks, if a cable breaks, you won't be able to get that gear down). I don't need flaps, speedbrakes, or thrust reversers to land safely. Max gear extending speed is 250 KIAS. Max gear extended speed is 292 KIAS (Vmo). So the gear can be dropped at high speed and stay out at higher speed. Mike C.

Quote: If I saw the hydraulic low level come on, I would be tempted to put the landing gear down immediately and fly gear down to a nearby safe landing. That makes sense, and fortunately it seems a rare event. Not sure how much engineering overlap, but in all the pro-junk cars I've driven in my life held together by rust, I only ever lost brakes from a sudden leak once. Maybe twice.

Well handled Mike. The Phenom has a page in the G1000 that monitors hydraulic pressure and will CAS message if it drops. Chip-

My largest bender is 1". Oil lines on the T-6/SNJ. When we install a spin on filter STC they call out long lengths of Mil-6000 hose, looks ugly. I'll make up 1" Alum Line and bead the ends. Connect with short Mil-6000 hose like all the stock, orig lines were. Looks much better.
