    Zinc additive by rislone ZDDP

    There are plenty of good studies (white paper type material) on ZDDP and its effects. Short answer is yes, there are limits to how much ZDDP is good. FWIW, ZDDP is not used in the typical aircraft engine oils. I would not be adding a bunch of anything to the oil without knowing what effects it...

    From pilot to A/P?

    Unfortunately, in one of the cases I mentioned that's basically what they basically did. I'm not happy about their decision, but I had no say in the matter either.

    From pilot to A/P?

    I agree for the most part, but I have seen a couple of guys get endorsed in the last 2-3 years that have had little or no documentation substantiating their experience, so as usual it seems to depend on who you ask and how the case is presented. If I were Rob I wouldn't give up hope without at...

    How to complete Bill of Sale when seller is LLC

    Are you the buyer or the seller here? If you're the seller you should know exactly how you filled out the paperwork when you bought it. If you're the buyer, I'd expect the seller to know how they filled out the bill of sale when they purchased it. Either way, as was already mentioned, the...

    M 350

    The general recommendation by most training providers is to set fuel flow at 22 gph on the Lycomings. In my experience, that’s about the right setting for ROP operations. I have run the Lycoming LOP, but mainly just to prove to myself that it could do it without problems. (The owner didn’t want...

    M 350

    I can’t comment on the 58P as I have no personal experience with it. The good thing about it is that it should fit in a normal T hangar while the Malibu won’t. Beyond that, my guess is that I’d probably still favor the PA46 but having more power would be nice.

    M 350

    What’s your intended use? Both are nice flying airplanes but for more flexibility and longer trips I’d take the quiet, pressurized cabin of a PA46 over a Baron almost every time.

    M 350

    I flew and maintained one for 5 years. They’re a 180 knot airplane down low and will do 200 at higher altitudes. The plane is nice to fly and very capable, although I think it would benefit from another 50-100 horsepower. The airframe itself was pretty simple and the systems are well thought...

    Gut Check: Is it a good plan in my situation to buy a plane for training?

    I'll spare you another round of warnings about taking out a loan for buying part of an aircraft and the unexpected financial drain it can turn into. I will say this however, I have yet to see a truly successful partnership that lasts for any real length of time. The warning that I will offer is...

    Cold Start Issues, Loss of EGT

    It sounds like morning sickness (sticky/tight valves).

    Any regrets moving up to better plane

    I've bought and sold a lot of aircraft, mostly for business purposes, but have owned 6 for my personal use. The first and last ones have been ~100 knot airplanes that are cheap to keep. I've found that I use the airplane a lot more when things aren't a hassle and when I don't have to think about...

    Can an annual substitute for a pre-purchase inspection? If an annual is done before the due date do any maintenance issues need to be fixed?

    There are multiple wing spar ADs so you need to make sure everyone is talking about the same one. If this guy has no money set aside for things such as an overhaul, that may be why he's looking for a partner and/or that may be the real reason the other guy wants to exit.

    Why is my mechanic so against a turbo?

    The concern your mechanic has might be more related to the specific aircraft type than it is with turbos in general. But as has already been mentioned, there is the potential for added maintenance expense. There may be minimal performance return on having a turbo depending on the aircraft...

    Engine Modification

    Correct. So you need to look at the data plate and see if it has the C suffix and if the logbook has any documentation concerning a conversion, and what it was converted to. If it is a conversion, then you need to figure out if it is an approved engine on the airframe, either via TC, STC, or...

    Engine Modification

    Assuming this is a TCd engine, more context may be needed. There are methods some use to do things like this via converting the engine to a different model. But converting the engine to a different model may make it ineligible to be on the airframe without further approval. Here’s an example of...

    How can certified avionics be so crappy?

    In my opinion, it is still relevant. Testing and certification costs in the automotive industry are high and thanks to trying to meet the increasingly difficult regulations while building to an affordable price point the durability/reliability of new vehicles and their components are slipping...

    How can certified avionics be so crappy?

    My point was that the OP suggested that there wasn’t as extensive certification done on automobiles. There most certainly is, and it costs the OEMs millions of dollars. Some areas of the US also expect continued compliance with the standards that the OEMs are held to via emissions checks and...

    How can certified avionics be so crappy?

    That is untrue in the automotive world. People just don’t understand what is done and how it is done. I work for an OEM and I’d bet our expenditures are much higher and more time consuming. Ever had an emissions check done on a car?

    "Inspected oil filter, found no metal" - myth or reality?

    Camguard's website claims it is an antiwear additive. https://aslcamguard.com/antiwear-performance/ That said, Camguard is not the same as what is in the Aeroshell plus oils and the Phillips Victory oils. A lot of people seem convinced it is, but there is plenty of evidence to the contrary out...
