Was not home today to talk to the problem solvers. I did however get an e-mail from Tecnam US. Capua supplied a part number to Sebring for blue silicon hose that they are apparently using for the application in question at the factory. Unfortunately Sebring doesn't have any in stock. So they did a quick search on the internet for an equivalent hose. The info for this hose was submitted for Tecnams approval. In the mean time they purchased some of this in bulk apparently in anticipation of Tecnams approval. They expect it to show up in 5 days. I am sure they will determine if the temp/pressure/compatibility specs are good. Hopefully they also determine that it is flexible enough to make the bend.

Buzz, could you post a pic of the hose? I'm curious if it is a 914 specific hose or common to all Rotax engines. No it is not common to all Rotax engines. This is the problem. It is a specific Tecnam part. This is why all of our favorite Rotax experts and parts suppliers know nothing about the hose. This is the way I am thinking about it. Remember this is a radiator hose going from the expansion chamber to wherever a manufacture decides to put the radiator. So it is a different configuration for each aircraft type. Rotax does not supply hoses for each manufactures arrangement. At least this is what I have been told and what I have surmised as I have worked on this issue. I haven't yet seen a Tecnam parts catalog drawing that even shows my exact setup. It might be out there but I haven't seen it. |

Well golly. Just when I thought my nightmare with the 5 year hose/rubber replacement couldn't get any worse. Today I went to the hangar because I was interested in checking out the location of my oil return line as a result of Rays incident. I found my return line to be about two finger widths from the exhaust manifold. It is zip tied up to the two oil lines for the turbo. The oil return line is in direct contact with the two turbo lines. Not sure if this is an issue. Not sure if this was how Rays issues started.
At any rate that is a side issue to what I found today as related to the 5 year replacement. As I was checking out my fuel lines I noticed an anomaly with the fire sleeve around the fuel line between the gascolator and the fuel pumps. The fire sleeve was lumpy and uneven. I ran my fingers over it feeling for the hose inside and it didn't feel right. So I pulled the sleeve back at both ends. To say I was shocked would be an understatement. I am not sure what I said but they were not happy words. Both ends the fuel hose are significantly twisted with the hose being collapsed impeading fuel flow. I have no doubt that at some RPM the demand would have out paced the ability of the hose to supply the fuel. These represent the 4th and 5th items my mechanic left me with that could have put me in the trees. I am exasperated and cranky. I talked to some others on the airport that have Rotax and think this guy is highly competent. He is well know in the aviation community here. Trying to decide what to do next. Not sure if I should talk to the FSDO. I would feel horrible if another customer ended up in the trees because I didn't say something. I will include pics of the fuel line.

Yikes!!! That's not me twisting the hose. I am simply sliding back the fire sleeve to expose the problem underneath. Attachments:

You bet that really could have effected I mean was effecting your fuel flow sure glad you caught it! Sure glad we get to share these finds here on Tecnam Talk.......... I am not sure how I would Handel your A&P that’s a tough call. The important thing is he’s aware of what he missed......... And yes, it does create doubt in your mind on what else did he miss? |

Another day more excuses. Today is 6 days since I was told by Tecnam US that they should have delivered to them in 5 days, a bulk supply of coolant hose that MIGHT be what I need. Not the specific Tecnam hose but a potential substitute. Again as stated before it would still need to be approved by Capua. So today I sent an e-mail to Tecnam and was told that unfortunately the hose has not yet been shipped to them by the supplier. So they did some searching in the supplies and came up with a silicon 90 degree formed hose that is used on the P2006. They took a picture, sent it to me, and asked if I thought it would work. How would I know? Aren't they the experts? Cant they determine this? Good Gawd!

My one learning is that I’m not doing a rubber replacement at my Annual in December unless Tecnam has this figured out.

Have been exchanging more e-mails today with Tecnam. Tecnam US said they had no way to determine if the P2006 hose would have worked so they have abandoned that idea. So you can see where that was going. They were willing to send me a hose that might not have worked. Total waste of time. So now I am told that there is bulk hose coming from Capua to Sebring. They will try tomorrow to find out an ETA to Sebring. This appears to be different than what I was being told. I was led to believe there was a substitute hose that they found on the internet. And that they had ordered bulk supply while they wait for approval of use from Capua. This was the hose that was estimated to show up in 5 day but as I said above, it hasn't been shipped yet. They are now telling me that they are waiting for a bulk supply from Capua that is presumable the correct part number. I am so confused.

As far as I know this one hose is the only one that needs to be acquired from Tecnam. You would have thunk that they would have it in stock sinse it is part of a 5 year replacement. So if all of this works out Tecnam US should have in stock the correct hose when you need it. Also remember that this small piece of hose will cost you $237.00. Make sure your mechanic has all the parts before taking anything apart. And one more thing. If you haven't already taken pictures, do it. Take all kinds of pictures at all angles of everything on your plane. Especially around the engine. |

We all owe you a couple beers once this is over Buzz. If Airventure happens next year, let’s get as many of us up there as possible. Buzz’s first ‘appreciation’ round is on me.
