66E: Flap Pump Fluid Supply Hose

[Nukemzzz]

So i found a cracked flare at my flap pump on the supply hose and I need to replace the hose between the flap pump and the metal line that runs along the firewall in the cabin.  The fitting is just to the right of the passenger's right ankle.  

I'm terrible with AN fitting Identification and my parts manual is MIA somewhere after my move.  Does anyone have the manual handy and know what I need to order to replace this guy?  I can measure the length, I just don't know what size and type of fitting I'm looking at.

Thanks

And yes, it's been a while since I've posted.  I have some reasons...

Plane was doing ok after that epic year long annual so I didn't have many issues to sort out.  Also, I moved... haven't flown in two months now because I've been too busy.  Also, FAA Medical sent me a letter and they still won't let me solo and it's kinda letting the wind out of my sails... sooner or later they will relent I hope.  I'm persistent (almost 2 years since I applied).  lol

Send it to specialty hose Corp in Canton OH
They will duplicate one for you.

That is low pressure hose, Stratoflex 193 hose and 311 fittings

[Nukemzzz]

Thanks Doc!

More information.  The hose is a -6 diameter, so Stratoflex 193-6 and the fitting 311-6.  However if it’s just the nut that is cracked, it’s just an AN 818-6.  The hose is fairly easy to build.

Nuke,

Is that a class III SI you are working on, or something more challenging?

There are quite a few people around here with special issuances…

From returning to work in the cockpit… to flying GA…

Don’t hide in the darkness trying to figure these out on your own… there is plenty of experience around here…

PP thoughts only…

Best regards,

All wrong !
 

Its 

mil h 8794 

3000 opsi

Milh5593 doesn’t have fabric cover

use Teflon with clear shrink for chafe

20% smaller od 

the hose size will be on socket or the an818 nut

 

I have been doing tso hoses since 1987

With all due respect you’re what we call Wrong.  The hose is actually low pressure instrument air hose.

It’s like milh8794 cover to me

Teflon is 20 % smaller od and non five year 

Use what you want as long as it has been pressure tested with date of mfg of hose and assy date 

The hose is low pressure on the suction side of the pump.  I don’t know how installing a Teflon hose would make it better?  These low pressure hoses have been installed for decades without issues.

Easy now, the issue will be..

Unless they are not rated for fluid and they will leak like crazy after 9years. 
I replaced mine with an oil line. The problem with a full size line is that it won’t clear the belly stringer. A Teflon line would be thinner and help with the install logistics. 
 

just went through this on mine,

If you look at the part number in the page from the IPC above you’ll note that it is SF193-311-311-6-20. Meaning StratoFlex 193 hose, 311 ends, -6  3/8” diameter hose 20” long.  While not really the type of hose one would expect to find in a hydraulic system, it’s what Mooney installed and has worked for decades on thousands of airframes.

Clarence, I think it’s pretty clear that Gee-Bee doesn’t care about the parts manual or what Mooney installed at the factory.  And it certainly seems like he doesn’t understand the low-pressure supply side of the hydraulic flap system.

He’s just trying to sell his stuff.

Rubber hose and fittings are now more expensive than med psi 1500 Teflon 

 

Neither of You are in the aircraft hose business.

Iam not selling, stating facts and options 

You all look at cost , not options or long term cost.

Iam one of the few that does the Pratt Whitney hoses

silver plated with lock wire holes

If you know so much, then neither of you need me .

 

 

 

No one is questioning the quality of the things you make, in fact I buy a number of them.  I question why one would need a Teflon hose with stainless steel ends when a simple rubber hose with aluminum ends has worked for the last 5 decades.  At this point I doubt the airframe will last longer with your nice Teflon hose than it would with a simple rubber hose which is worth $40 CDN at Spruce.

Class III yes.  It’s been a real pisser. I’m approaching my second year of ownership and my flight training has been waiting on my ticket for most of it. I’ve gone back and forth with FAA medical and spent at least $5,000.  Right now I’m waiting on a the second written evaluation from a neurologist. (They’ve sent me to one twice now). I had to pay a physiologist $3,300 for him to talk to me for a couple of hours and write a report.  It’s been a long and trying thing.  I called AOPA a couple of times. Their advice is to bend over and grab my ankles and don’t bother trying to protect my wallet. 
 

I’m really hoping to get approval by winter. I’ve practically rebuilt my 66E, spent $260 a month to hangar it, and two years of insurance. I got it hoping to visit my ailing mother more often with it…she passed on before I could get it done. Now my father is alone and I need to be able to get to him easier and we have precious little time to chase each other in our planes…while he still can. I was his co-pilot as a child. It’s about to be his turn to be mine. 
 

Just have to carry on…

Thanks for the continued discussion on this guys. My friend that helps me with this sort of thing went and bought the hose that he thought I needed and it doesn’t fit. The fitting is too big and the hose OD is too big. I sent him after what you recommended Clarence and when I ended up with the other he said: “but that other hose is air hose”.  So, I’m still working on this. I’ll probably just get what the manual calls for because it’s just hydraulic fluid storage. Though I need to research the ends to be sure they aren’t too big as well. It just barely fits between the cabin and the frame. 
 

Thanks again!

I’ll build you the hose if you’d like.

The fittings on the left are 311 series which have been installed on 111 hose instead of 193 hose per the IPC.

We have too much in common….  

My challenge with the Class III SI….   It took six months to collect all the data…

the first time through, it was all new to me… spent six months not flying….

The SI ran out after a year… so I started collecting data again….

The FAA can really be a tangled web… They lost one of my packages of data…

 

End result…. 
 

Going with basic med is perfect for most GA pilots… as long as you haven’t failed a Class III…

If going Basic Med… there are a few limitations to be familiar with…

 

If you clog an artery… then have the artery unclogged quick enough…. No harm, no foul… proving that to the FAA year after year can be a serious hassle… 

Before, I used to run a 7 minute mile… After, my mile time slowed to eight minutes… my typical jog is four miles a few times each week…

Wish I could have just submitted a video of one of my jogs…

It is really helpful to have the right AME working with you on your project… they have a way of getting through to the FAA that we can’t…

I guess the good news is I haven’t failed it yet. I just have a few things in my record that they don’t like.  For example, I took SSRI briefly during my divorce (it was bad, let me tell you). I also had a car crash with the cause being “I passed out” and we never sorted exactly why it happened.  This is pretty much exactly the kind of thing they are looking for. Now we have it sorted: vagus vagul nerve triggered low blood pressure and I hyperventilated.   I’m waiting on a second letter from the neurologist that makes it clear that he understands. 
 

Is special issuance shorter duration normally?  I sure hope they don’t put some restrictions on me after all of this. I have no idea of what to expect. 
 

btw…you could run circles around me with your cardio.  

[carusoam]

@Nukemzzz,

My SI only lasted a year.  I thought after everything settled out… the restrictions would lighten up…

Apparently, the FAA doesn’t see it the same way as I did….  

The key thing… if you haven’t failed a Class III medical… this is helpful for going Basic Med…. If you have a class III failure at the end of your record… this limits your ability to go basic med…

Essentially, the FAA has left the door open, with a don’t ask, don’t tell clause….

Don’t accidentally go in for a Class III without knowing all your ducks are in a row… 

 

To improve on the down time… once you know all the hoops they make you jump through… you can probably send a new package of data in before they ask for it…. (Could be too forward thinking)…

Lots of mailing things back and forth led to months of delays…

My actual tests can be completed in a couple of hours…. Picture of the heart, EKG, Bruce treadmill stress test…. All local heart doctor stuff…

Run the treadmill test…. They think your are suposed to die when you walk in… it’s like jogging up hill… not that big of deal for my challenge… 

 

Try to find an AME that is already familiar with your type of challenge….  My AME is good… but he is a bone doctor, not very familiar with heart issues…

Check the list of Meds that are OK… AOPA covers this topic quite well…. Some things require a mandatory wait of six months before you can fly again….  
 

As usual…. It’s fun being a human being….

Any A&P is legal to make the hose up but will they?   Many are afraid- afraid of what I have no idea but they learned how in A&P school.
