Hi all, Was making a short Flt to Mesquite NV 67L 50 min flt from my Home airport KBVU Boulder City. I noticed a drop in oil pressure. Luckily by pure luck I was already on final approach the best part was I did not completely lose all oil pressure. Had I flown another 30 mins the results would have been drastically different. I had planed to fly to KCDC Cedar City UT another 70 mins flt time. I decided to stop for a short bathroom break. When I excited the airplane I could smell burned oil and there was a small amount of smoke coming from the engine cowl and the belly was completely covered nose to tail. I even noticed a slight variation in the elevator it was pitching up and down slightly from the oil changing the air flow around the stabilator.. Had never felt that before another small indication there was a problem.
Had I few the trip as planned it would have completely burned up the engine and an off airport landing surely would have happened ( Thank God for Bathroom breaks ) as it was I. Lost about a qt of oil it looked a lot worse than it was. I made a temporary fix and put in a fuel lines splice.... Did a thirty min engine run all good and replaced the lost oil just a little over a qt. As a precaution I pulled the magnetic plug to check for metal all good. Once I made it back to Boulder City I cut the oil filter to again make sure there was no metal particles all good. Tecnam is making a new line and since it’s under warranty paying all associated cost......... Here are some pictures of how it looked just wanted to share my experience with you all. You Turbo owners take an extra look at the oil return line an make sure it is not to close the exhaust manifold. Ray & Lucy ✈️✅😎😊👍🏻🇺🇸Attachments:

First of all very happy you are ok...yikes. So are you saying the oil line melted? Did it have fire sleeve? And when you say return line are you saying return to engine or return to sump? |

 Hi Buzz, Yes, it did have the fire sleeve and yes it’s the oil return line from the bottom of the engine to the top of the oil tank. I tried to upload more pictures but no luck ? I appreciate your concern also I hope you get your new coolant line. Did you check that link I sent you with the three day turn around? Ray & Lucy ✈️✅😎😎👍🏻😊🇺🇸 |

Kind of hard to see in the pics. Was the line in direct contact? If so what was it touching? Yes I looked at the link thanks. I should be hearing from Josh this week about the hose he purchased. Obviously he will not send me this hose if Tecnam does not give the ok. My concern is that any approval from Capua might take forever. If no progress on Monday then I will look at other options including what you sent me. Going to go look at my return line today and see how close it is to things

Sorry, I think you already said the exhaust manifold was the source of heat.

I think this company is your best shot these guys are here ........ Hard to beat a three day turn around...... I am sure the Italians would sign off with what they manufacture for you and the price probably would be half or better.......... Glad you are considering this....... I have many friends that use this company for there certified aircraft with absolutely no issues and are happy and safe..... Ray & Lucy ✅✈️✈️👍🏻😊😊🇺🇸 |

Ray what caused the melting. Was the return line in direct contact with the exhaust manifold? Or was it radiant? I checked mine and I have two finger width distance to the manifold but it is zip tied up to the bottom of the two turbo oil lines. Direct contact with the turbo lines.

Hi Buzz,
Yes, the oil return line was directly on top of the exhaust manifold....... just wish I would have caught it before it burned though......

Oh I see. Yikes not good. Sounds like a Q/A with Tecnam. Like I said mine has a zip tie in the location keeping the return line separated from the manifold.

Keep an eye on those zip ties. The heat makes them brittle and they will break. I found one on the ground in front of my hangar one day. Might be worth a double zip tie in that location.
