This is the issue I see. The drawing was supplied to the owner by the maker of the part. Not the other way around. They may be perfectly within the requirements, but it looks like there may be an issue, so FAA investigates. Explaining exactly how you meet the requirements should clear things up.

Can you add the second AHRS later? If so, I would have considered making the wiring setup for that. Yes, as I understand it, the 7" can be reversion for the 10" failure. I also am thinking that a 7" can be used by the right seater to fly. With a 750, they would have nav/MFD handy Although, I was just looking over at BT and one person put a 7" on the right with second G-5. I don't think we have the panel space in a Mooney to do that

But the post I was replying to implied a vapor pressure difference based on octane. BTW, butane has an octane rating around 94. And is a gas at room temperature.

I understand your concern. But I know my welding skills, so fine with it. Actually, looking at the Mooney produced part, I am not impressed with the welding.

But that they did so was not clear. That is why there is an investigation. If they provide the info that shows they met the requirements, then the FAA should be happy. As the situation was stated, it did not meet the requirements.

If a BIG lottery, I would contact those guys in NZ and have them do a Mosquito Mark VI for me. What is better than a Merlin? TWO Merlins.

Maryland requires a whopping $30,000 for bodily injury. And $15,000 for property damage. Hmm, so what happens when the hit and total that brand new $60,000 BMW or Mercedes or Audi or Corvette????? The thing is, more insurance is not that much more expensive. I was doing an insurance review and to bump my limits from $100,000 to $1,000,000 was about $6 per year. Yes SIX DOLLARS.

I hope you have your Part 107 Remote Pilot Certificate.

Late to the party, but I would have done a GTN-750Xi and dropped the 7" G3X. I think you need the G-5 as backup. There is an upgrade ($$$) to have the 7" screen be a backup PFD with its own AHARS, but it is not cheap. But then you need to power it separately. And the G-5 has an internal battery good for 4 hours in case of electrical failure. Of course, you could put in the 750Xi and also do the 7" G3X, but put it to the right for someone in the right seat to use as MFD or PFD.

Mike Busch article on OPP - https://resources.savvyaviation.com/wp-content/uploads/articles_eaa/EAA_2011-08_owner-produced-parts.pdf The key is, the owner must do one of the following: • Provides the manufacturer with design or performance data from which to manufacture the part—this test would be met if the owner provides the manufacturer with the old part and asks that it be duplicated; or • Provides materials to make the part; or • Provides fabrication processes or assembly methods to be used in making the part; or • Provides quality control procedures to be used in making the part; or • Supervises the manufacture of the part. So, where I see the issue with the parts in question, one person sent in a part. Drawings were made, that went directly to the company making the part and the parts, with the drawing, were sent to a number of owners. The person who sent the original part, has an OPP. The others do not. IMO, if the drawing had been sent to each of them, and they each sent the drawing to the shop to have the part made, it would meet the test of OPP. Or, they could have ordered the block of aluminum to be delivered to the shop to fabricate their part.

This should be a sticky so new people can see it. I did not see it. My name is Terry. And I am a Mooniac I grew up around aviation. My Dad was a Naval Aviator flying carrier based anti submarine warfare from 1950 - 1966, then he became a staff guy. I started flying with Civil Air Patrol in high school, but then got side tracked by fumes. Gas fumes (cars) and perfumes (girls). And got out of flying. My senior year in college, I decided I wanted to try to get a military slot. And thought, it would help to start flying again. So I found a school not too far away and started training in a Grumman Tiger. Off a 2000 foot strip. I was accepted by the Navy and Air Force, then found out about the Air National Guard. I applied to my local unit and was accepted. I was commissioned September 1980 then attended Undergraduate Pilot Training at Laughlin AFB in Del Rio, TX. I earned my wings October 1981. I continued my training and returned to my ANG unit to fly the A-10. After a few years, due to a medical issue, I got out of flying again. This time I got into racing sailboats, owning a Laser 28. After a break, I returned to flying, adding some ratings and having a good time flying OPAs (Other Peoples Aircraft). A friend bought a T-34, and put me on the insurance and I did a number of airshows with it. Including participating in a 63 airplane formation at Oshkosh 1999 opening day for the 50th anniversary of the T-34. That airplane was lost on April 10, 2001 coming back from Sun n Fun. My friend was killed, and I spend over 3 months in a burn center. So I took another hiatus from flying, with an occasional flight with friends. I did get back into performance cars and road racing. I still teach high performance driving at Summit Point raceway in WV. About 18 months ago, I decided to get back into flying. I rejoined CAP (NOT the CAP of the old days) to fly their airplanes (free flying) and to get involved in bringing aviation to a younger generation. About 10 months ago, I had some changes to my financial situation and decided to buy a plane. I looked at Tiger's, drooled over Aerostars (but cringed at the operating costs), and finally decided a Mooney was for me. I finally found the right plane and purchased it. I wrote an article for Mooney Flyer about my journey to becoming a Mooniac, published in the Sept 2022 issue. I have gathered a few ratings along the way. I am hold a Commercial Pilot certificate, with ASMEL, IA, RH, and G ratings, plus Private ASES. I have a CFI (not current) with ASE, IA, RH, and G ratings. I plan on renewing my CFI this spring by adding the MEI rating. And probably redo my ASES to the Commercial level. Professionally, I do occupational health and safety. I recently retired from the Federal Government, but in true gov worker fashion, I will start back part time in February.

CG is CG. AFAIK the F/J and K have the same CG range.

You need to do the APS seminar and learn about the BMP (Big Mixture Pull) for running your engine. the TSIO-360-SB in my Mooney runs about 25 - 26 GPH at full power. And I climb at full power, max RPM, full rich. But that is with a turbo.

That is not true as a blanket statement. Octane and volatiles are two totally different things. All that octane tells you is the resistance to detonation. NOTHING else. Toluene is very volatile, but high octane. (MON 107, RON 121). Auto fuel is blending to different vapor pressures for different conditions, making cold starting easier. IF you have a winter blend fuel. If you fill up in the middle of summer, and not use up that fuel, it will be just as hard to start on summer auto gas and avgas in the winter.

However those Fortune 500 CEOs have golden parachutes and stock options. Their salary is NOT what they make.

I recently considered the OPP path. I need two adjustable links for the pedals to the master cylinders. It is a rod end bearing ($35 retail), a clevis ($19 retail) and two pieces of steel tubing, about 3 inches total. Three welds and some paint. Mooney charged over $600 to manufacture (LASAR had one for under $300). I have a TIG welder and know how to use it. I could have fabricated two for around $100 in materials. HIGHLY agree that if Mooney does not have parts available at reasonable prices, people will OPP, or PMA holders will move in.

From what I see, this is the issue. If they had paid to get the drawing made, then each supplied the drawing, and the fabricator realized they were the same and did a CNC file to make them, that is OPP. But it was stated that the drawing was sent to the owner with the part. That is not the owner supplying the specs. Sorry people, but laws and regulations ARE semantics. And how you read laws and regulations is very specific.

Always seem to be a bunch for sale on Controller and Trade-a-Plane. Another option is to contact Jimmy Garrison at GMax. He normally has a few

But G1000 is a different system than the standard K setup

Yes, this is why checking the emergency gear is down and latched is at least twice in the checklists before take off.

Powerball is $526 million today.... One would not be enough. But ..... First a T-34A with IO-550. Fun to fly, very active type club with fly in activities. Can do airshows as a Warbird. Second an Aerostar. Love how they look, love how the fly. Third a CAP-10C. Mainly to offer aerobatic/upset training. Maybe a Phenom 300E (or PC-24) single pilot jet for longer trips.

You can say that about people in general.

Yes. And you can even use it in your car.

I would LOVE to have an Aerostar. Operating costs are just a bit out of my budget. But if I win the lottery, I WILL have one.

Simple chemistry. Natural gas is mainly methane. That is CH4. Fully combusted makes 1 molecule CO2 and 2 molecule of H2O. Propane is C3H8. Make 3x CO2 and 4x H20 Isooctane is C8H18. Makes 8x CO2 and 9x H20. The ratio of hydrogen to carbon goes down with more complex hydrocarbons, so more CO2 versus H20. BUT, realize the number one green house gas is actually water vapor.
