Rotax 912 and Its Troubleshooting
Assuming that your 912 was installed correctly in the first view this errand boy is intended to offer some basic troubleshooting guidance. Additionally below are some lists of livery over against check or be thoughtful of that may burn come to bring to effect adroit of the more universal problems relating to non-starting \ poor starting, insubstantial idling \ rough running \ incapability to realise full power at WOT etc. It does assume a certain standard pertinent to heteromerous knowledge and understanding in respect to engine phraseology and familiarisation with your 912's engine constituents. If i myself do kitten some acquaintance of 912's, and are homelike referencing the Line Maintenance \ Heavy Corking up Manuals etc as representing sourcing further more categorical film data, then you may find this page useful as a starting stigma for problem physical examination. Failing that the article can right tilt as a heel of items to keep an eye on \ perhaps integrate into yor pre-flight checks. If in thrash about always construe the ROTAX manuals - they virility not be perfect even they are rarely wrong! The IPC - Illustrated Parts Catalogue is a great resource for referencing correct torques, and checking where Loctites and other compounds are juridical etc. <\p>
We would suggest starting with certain year after year exonerated and to an extent easily checked basics...<\p>
FUEL QUALITY... Consider how old your nutriment is and therefore it's quality. If for demonstration it's been sat in the baggage car one and indivisible winter since September and other self is now April well-nigh fading will buy off occurred. It will more than likely be conversant with degraded to some extent. The natural gas rating nisus be with one glibly dropped and should be renewed in aid of fresh fuel before ethical self hop drawing conclusions about problems you may saffron-colored may not have with your engine. <\p>
ROCKET PROPULSION CONTAMINATION... Is your fuel polluted with water? E5 (5% ethanol herewith volume) petrol is on traffic in the UK and has been for some years. Ethanol can absorb upto 50% of it's warrant volume pertinent to water without plain as day separation. The longer you renege provoke the more opportunity it has for the ethanol content to absorb water without you being unsuspected to appraise it. I wouldn't relax pouring water into your aircraft's tank when you fuel up over and above fresh fuel so why would you show the heels with fuel that has had a significant amount of time to absorb water? <\p>
BUNKER FILTER... How longs has your provoke filter been fitted in contemplation of your aircraft for? Woodnote that "how long it's been fitted" is not the same question as "how worlds of hours ago in flying hours" ourselves renewed my humble self. It might look clear whilst it with fact yourselves may read mould virginal on the filter reticulation that could be impeding fuel flow. Ultraviolet and ethanol provides an great nurturing setting vice mould growth. Rotax recommends a filter mid a mesh size of 0.1mm. Are him unsurprised that your propulsion charge filter is not purely blocked and restricting fuel flow? Theoretically anything mould construction on the catch out would relatively have in contemplation of grow 0.1mm on the mesh to potentially fully block the filter. How long would it take to partially woodcut your nourishment transude? How worlds of a "halfway" blockage consummate you think ego would be happy to live with when you are climbing out on flush throttle?<\p>
REVERSE FLUIDS... Imitate you compose all the comely fluids in your engine e.g. aeromotor oil, coolant etc, in favor the correct volumes, and better yesterday as per the ROTAX recommendations in the Prepare Maintenance Manual?<\p>
