    Cont GO300 cylinders??

    Yes not operating per POH was a problem as well but my conclusion/theory has been that another contributing factor is the installation of O-300 cylinders leading to premature failures. I'm no cylinder expert, just what I came up with several years ago. Keep us updated on your search...

    Cont GO300 cylinders??

    They are different and cannot be converted. I believe the GO-300's reputation would be much better today if Continental would have made sure that the O-300 cylinders could NOT bolt on to a GO-300. I'll attempt to share the pics...

    Cessna 172 Heated Pitot Drawings

    Hello, Wondering if anyone has the Cessna drawings for installing the optional heated pitot? I have found some reference to AK175-23D but have not been able to find the actual documents. Thank you!

    Cessna 172 panel gut job

    That's a good idea actually, hadn't thought about a document CD. If it was a log book sign off it wouldn't show up but if it was an STC or field approval then it would. I do struggle with this a bit. I have had avionics guys tell me that they do this (see pic) to Cherokees all the time...

    Cessna 172 panel gut job

    Its back... the whole topic was removed yesterday for some reason. Here's another one. The same question still stands. If you have any input to the actual question it is greatly appreciated. How do I go about making this instrument panel restructuring legal, on paper that is? What I have...

    Cessna 172 panel gut job

    Thank you for taking the time for this response!! You mention other alterations such as the basic design of electrical system. I've heard much debate over what is major and what is minor in this area too. Perhaps this is the same answer for the panel as well... that there isn't one. at least...

    Cessna 172 panel gut job

    Lol, I appreciate all the comments but I think I need to rephrase my question... I'm just trying to learn from those that have done the type of work being done in the pic what process was used to make it legal. I don't believe that an A&P can simply sign this off because it is technically a...

    Cessna 172 panel gut job

    Yes that's what I'm looking for. To do this to a panel where do I start? Do I have to go straight to a DER to get approved data? Will Cessna give the blessing on such work? For those that have done a major panel gut job like the one in the pic by what means are you getting it approved?

    Cessna 172 Garmin Upgrade. GEA 24 EIS or JPI 900

    Can I ask why you decided on the G500 over the G3X?

    Cessna 172 Garmin Upgrade. GEA 24 EIS or JPI 900

    I agree its not NEEDED, however if those old stewart warner gauges tell you something is wrong... its likely way too late :) In the grand scheme of things the engine monitor is far from the bulk of the cost and as much as this project is going to cost I want to do it right the first time. I...

    Cessna 172 Garmin Upgrade. GEA 24 EIS or JPI 900

    So have been racking my brain over a Garmin upgrade and there are so many possible configs. Its big $$$ so thought I'd reach out for some additional comments and recommendations beyond the bias of the Garmin dealer. So far looking at G3X, GTN650, GNC255, GTX345, GI275, GFC500. Not sure if I...

    KX155 with amplifier option how to wire to new audio panel

    Yes it has same pinouts so thinking I can just wire it as if its not there? It never had an audio panel before. Thankyou

    KX155 with amplifier option how to wire to new audio panel

    Hoping someone has run into this before. I was going to install a new audio panel with my KX-155 and discovered that it is the version with internal audio amplifier. Does anyone know if I can just wire it as if it does not have the amplifier using dwg 155-01343-0000? Thankyou!

    Oil and Unleaded fuel

    The "snake oil" is required for those few engines but also for any running unleaded fuel per 1070 but perhaps it still isn't truly "mandatory" because it's not tied to an AD. The "few" engines you referred to have ADs to use the snake oil? Seems like they did.

    Oil and Unleaded fuel

    Paul, I'll have to look into that. I was assuming that it would be mandatory as my POH references the 1070 and the 1070 states its "mandatory" but now that you mention it I have heard that it is only a recommendation until it is an AD My engine is an O-360-A4A

    Oil and Unleaded fuel

    From what I understand aeroshell had to modify their oil's formula after starting to add the LW-16702 due to increased copper levels. So it doesn't seem like a good idea to use the the additive on just any oil. Also the reason I didn't use aeroshell was due to it containing the additive. If I am...
