Gotta put in a sanity check here. I rushed out and ordered and then waited 9 months to get the oil pressure relief "kit". This cost me around $100 for parts and will cost an hour's time for a Rotax approved mechanic to install. What will I accomplish with this? I don't have an oil pressure problem and installation of these parts won't help me with warranty because I'm well past this. If I ever sell my CTSW, it may (may) be a good selling point that my engine is up to date with all Rotax required parts? I don't intend to sell my plane for a long time and most probably my estate will have to deal with it after my passing. Now, what about the rubber parts replacement? Is there REALLY a need to replace the hoses after 5 years? Recall that all of these components, including carburetor rubber, is inspected each 100 hours. I am not an expert on Rotax and so I have to assume that the rubber parts will have deteriorated sufficiently in 5 years that they will need replacement. Or, is there evidence that a "more thorough" annual inspection of these parts, which would include detachment of oil and water hoses to inspect them, may be sufficient to insure that I am OK not replacing them?
If there was a choice as to where these parts could be obtained, maybe this requirement might be a little easier to accept. I see that I can buy a aftermarket VDO oil pressure sender for around $30 compared to the Rotax sender which is in the $200+ range. I'm trying to brace myself for the cost of new rubber when the time comes next year to replace parts but I'm sure that I will still be surprised by the cost. Of course, there will probably be the wait for parts. It is understood that flying is an expensive sport and all owners know that it is their responsibility to insure that they maintain their aircraft in a condition for safe flight. If my CTSW truely needs new rubber, then I'll pony up with the money and do it. I'm just not 100% sure that it is "carte blanche" required and think that a "condition inspection", at least for a couple more years of TIS, would be a consideration. I welcome forum comments.
