Hi Maj Thank you and every one else for there concern My Mechanic Len checked out the plane this morning upon taking it for a test flight found the same problem, with a bit of vibration and definite lose of power. So back to the hangar and a thorough check of all the fuel system, we found the problem. The fuel line star that's a 4 way section that distributes the fuel to both carburettors and to the fuel pressure gauge had been inadvertently put back the wrong way, with restricted supply to one of the carburettors, instead of to the fuel pressure gauge Once again a lesson learnt one cannot afford to not pay full attention to the smallest of parts This little 4 way piece of junction pipe has a restriction that can be easily overlooked at the best of times Cheers Dave

I believe we have sussed out the problem just ran out of daylight today, so did not get to test fly the Tecnam. Me being a nervous pilot, who only fly's on very fine calm days, and having a bit of vibration on climb out at app 200ft with a bit of panic thrown in who immediately throttled of and pushed the stick forward and landing straight ahead thinking i had a fuel problem. putting it down to maybe air in the fuel lines, only to do the same again the next day after bleeding the fuel lines to make sure all would be ok and finding the vibration even more extreme. as i lift the flaps at about 2 to 300 ft and making that decision to land straight ahead once again as trained to do in the event of efato or any other event that would effect the the safety of self or the plane we have come to the conclusion that it was the Tyre that i changed the other day causing one of the landing wheels to become out of balance and not doing its chronic boogie until well into lift off. this has now been rectified Doh Dave

Duno wot part of the world you are in Bryon, but it is still only 3.30 am Wednesday morning here

I will confess all on Wednesday evening, after we have confirmed and remedied the problem, not as serious as first thought Cheers Dave

we have sussed out what we think is the problem, do not think it to be a fuel problem after all, will confirm an Wednesday after we finish all the maintenance issues Thanks for every ones input all the same Cheers Dave

Yes mine also has a restrictor in the tee for the return working ok We have just checked out both mech.fuel pump and the electric fuel pump both working ok, as separate units, and in tandem we have also ran a couple of ltrs of fuel thou the system to make sure no air left in the fuel lines we are about to test engine then test fly Cheers Dave

Just had my first splutter after takeoff today stick forward and landed straight ahead made it down ok We had just finished replacing all the fuel lines in the Tecnam including emptying both tanks and replacing the fuel. checked out for any leaks and loose fittings all ok next turned on electric fuel pump every thing ok next fired up the trusty Rotax ran it for a couple of minutes all ok then proceeded to put the cowlings and final cleanup and DI befor taking it out for a check flight Approximately 5 or six minutes for warm up while taxing out all the pre take off checks including mags. check all ok lined up on the runway every thing running smoothly like all ways, lift of at 40 knots flaps up climbing at 65 knots then a splutter. after landing could not find any faults. Question is could it have been air in the fuel lines ? can any one give some input with the same experience Next Day Well we checked every thing out again this time holding the breaks on and running engine at full revs for app 2 minutes then the same again this time with electric fuel pump on as well. did not miss a beat so lined up and climbed out at around 300 feet the engine started to run rough with loss of power once again stick forward throttle off almost through the boundary fence this time. Another near death experience

Hi Bryon Well we checked every thing out again this time holding the breaks on and running engine at full revs for app 2 minutes then the same again this time with electric fuel pump on as well. did not miss a beat so lined up and climbed out at around 300 feet the engine started to run rough with loss of power once again stick forward throttle off almost through the boundary fence this time.

I have just found my first problem with my Tecnam P92 echo super after 3 years and just over 200 hours. opon aplying the breaks and turning the little tap (same as fuel tap) between the seats to lock the brakes on as in hand break, I found it not holding. so on consulting my trusty mechanic, we purchased a new hand break tap, this did not remedy the problem, the next was to bleed the whole system No joy.next was to trace the break system and behind the seats found a one way valve that we pulled apart and found a broken O ring, this little valve has the smallest O ring i have ever seen it would just fit over the end of a match. Problem Solverd Cheers TecnamDave

stupid but not funny flying hi ?

Thanks for the welcome guys and Gals its a great landing field Dave

Gday Dave here I have a tonini propeller that has a small split or chip on the tip it is off my tecnam and i have replaced it with a new one i would like a second opinion by someone that could posibly repair it and if so to be kept as a spare i have asked around so far cannot find anyone qualified

Gday just made another safe landing first time on this strip hope to make many more my name is Dave and I am the proud owner of a Tecnam p92 rg 2000 I fly at Gawler in south australia have yet to master the navigation side of things cheers
