Alright Mooney group bear with me, this may get a little long winded. New Pilot and even Newer Mooney pilot. So, i just finished my 15 hours to be checked off by insurance. I now have about 20 hours in my new (to us) 1967 F model. We bought it with about 25 hours on a new engine, and just completed our first oil change as well. Lots of firsts going on here. So, I am new to complex aircraft as well. When performing our run up we normally lean the mixture to best power similar to what we did in the 172. Run up to 1800 rpm, full forward on the prop, and slowly lean until power loss catch it and give a few extra turns once the power is back. Then we pretty much haven't touched the mixture on any flight. I played with it a little the other day in cruise, lowering it until it got rough and then adding it back in until it was smooth. Our checkmate checklist says cruise around 2600 rpm on the prop, but once setting the prop you cannot use RPM as a good lean indicator correct? Plus to add to complication our fuel pressure gauge is out (so I cant just put it at the bottom of the green) which would be running it efficiently correct? (Also new avionics coming in a couple months) So the only time I have tried to lean it in flight was in a cruise the other day I leaned it until it ran rough, then twisted it back in to run smoothly. Which the POH says don't lean the power above 75% power... but at full throttle I am sure I am above that. Did I hurt the motor? How on earth do you calculate percentage of power? Then there is the throttle. I figured on a brand new engine you wouldn't want to run it at WOT all the time due to wear on a new engine. But my CFI said run it full and manage RPM and Fuel flow with the mixture and prop, but my Dad (Airforce Pilot/commercial pilot of 30 years) said he would also be worried about wear on the engine, but thoroughly admitted I probably have more experience in a civilian airplane than him at this point. Ours is also turbo normalized as well, and all I have been told about it is to keep it below 28 MP. All of this has added a ton of confusion in my mind, so I went to the internet. Specifically another post on here: Which added even more confusion. I also realize I probably sound like an idiot, but I am okay with that if it helps me figure all this out by asking the experts. So to summarize my questions: 1) Is our best mixture practice during run up correct? 2) When leaning for efficiency, can you use RPM drop with a constant speed prop, fuel pressure indication, or leaning it until its rough then adding it back in? Which is correct or are all correct and some are just better than the other. 3) Is WOT the correct way to fly? Is the POH out of date as stated in the message board above. 4) Is 2600 RPM that the checkmate suggests the best cruise setting on prop? 5) Have I hurt the engine buy leaning with full throttle in and potentially getting over 75% power setting? 6) How on earth do you correctly measure % of power? (This one is probably easy but I am missing it) 7) Does any of this change when adding in the turbo? Thanks everyone!!! I know that is a lot to follow but any response, guidance, or videos would be much appreciated. Fly safe, The FNG

Hi, Any performance specialists? I'm interested to understand the takeoff performance differences in the J model. Apart form some aerodynamic improvements the sizeable disparity between the attached 1977 and 1996 issued POH in takeoff performance I attribute to A) regulator imposing increased factoring / buffer inbuilt as time went on and/or the 'speed at 50ft'. I note the stall speeds in both books listed as 57kt in takeoff config (Flap 15 deg), yet the speed at 50ft in the 1977 book only 71kts and in the 1996 book 76kts . The lower margin above stall speed will achieve better numbers for takeoff distance I understand but I'm not certain its the only factor at play here in the differences. 71 kts is 24.56% margin above stall and 76 kts is 33.33% margin above 1G stall. Takeoff Safety speed for light aircraft I believe has to be at least 20 percent above stall speed?? Was there an FAA change at some stage on this? Are the 1977 figures allowed to be used... certainly not providing as much margin as later book data in the real world.

Anyone know where I can order a POH binder replacement?

Going through my POH and realized I didn't have several components of AFMS/Supplements in the POH. I reached out to the avionics installer (Thanks for the help Rick McKewon at J&R) and he sent me AFMS/STC for the avionics they installed. But I still didn't have supplements for things like autopilot, speed brakes, oxygen system... Just wondering what most standard Mooneys came with in the POH... and wondering what exactly I SHOULD have in the POH/supplements or AFMS binder... I attached the files that I found online. Oxygen_AFMS.pdf King 150 AP AFMS.pdf GTX330_AFMS.pdf GTN750_AFMS_STC.pdf GTN650_AFMS_STC.pdf G500_AFMS.pdf PreciseFlightSBS_AFMS.pdf

I'm in need of a copy of a STC and POH Supplements for a Short Body Mooney M20C or M20E. I also need a copy of the Installation instructions for the Short Body Mooney M20 Series as well if anyone has a copy. This is for supporting documentation to be submitted for a Field Pre Approval for my M20A with a M20E Wing. I have already purchased a complete S-Tec 30 system and I'm well on my way to applying for the field approval. Any assistance is greatly appreciated. Thanks in advance! Carl

I’m upgrading my M20K 252 to an Encore with SB engine and dual caliper brakes. I need an Encore POH in printed or .pdf format. Does any have one to sell or know where I can get one?

Hello All, I'm in need of a POH for the Ovation2 s/n 29-0323 to 29-0332. any ideas?

who owns it

This site is a great resource to share ideas and experiences. Hope it stays so, but I just read a thread thread this morning about flying above gross weight which was reinvigorated by a person looking for a copy of a Mooney Parts Catalog and Maintenance Manual and it got me thinking about another "technical" or is it "actual" violation of law which may expose this entire site or the culpable individuals to a law suit. I doubt Mooney would actually do it since this site is one of their best advertising streams, but I would say they have all rights to do so to anyone sharing their digital data without permission. Selling an original Mooney bound book or a Mooney thumb-drive bought from the company would be like going to a used book store, but anything else is possibly theft of intellectual property. Did Mooney as corporation give such permission carte blanche to this site? The thumb-drive data I have shows a copyright. Those looking for Mooney Pubs could just call them and have them sent. Service & Parts (830) 792-2901 or email technicalsupport@mooney.com. They tend to be very responsive. It is possible that I am missing a key piece of information on this and I am not a lawyer......I just want to make sure if the data he needs it is not a violation of Copyright Law. Kinda like the Napster thing was. Thoughts?

I'm making up my own checklists for my 1962 M20C, and as I'm writing them up, I'm cross referencing them with the POH. As I read through the manuals they specify running the Carbureted O-360 engine Lean of Peak, as far as I can tell! I have always understood that this was a VERY questionable idea, pretty much asking for trouble. I cross referenced this with the manual for a 1967 M20C, and the advice was the same. Does anyone run 25 Deg LOP as the manual describes? Here is the paragraph in question: Lean the mixture for smooth operation (reference Lycoming's Operators Manual.) The Exhaust Gas Temperature Indicator is to be used only as an aid in setting the mixture during cruse at powers up to 75% power, but not take-off, climb, or descent. For lean-out procedures at 75% power or lower, lean to peak temperature, then lean until temperature drops 25 Deg F. minimum. In the '67 manual, it continues talking about Best Power Setting: To obtain a best power (maximum airspeed) setting, lean to peak temperature and then enrich mixture (push control forward) until the indicator shows a 100 Deg F. drop (four marks on the gauge) from the peak temperature. This has probably been discussed before, but I couldn't find it in a search. Thanks, James

Hi there, does anyone have an electronic version of the POH for an M20E (1966)?

Hi everyone, been a while since i came here ! first time i post on the new board... I was wondering if any of you knew where i could find what's in the title (POH for M20J and 252 in electronic format). I'd like to know these two better Thanks in advance for your help !
