Hey Caleb, Welcome to Mooney ownership!! I bought into a partnership in a G model in 1985, in 1997 I bought a E model for myself. I remember those first flights like they were yesterday. I guess your will too Classic paint job - nice.

I hope there is an alternative solution.

@kehdri: My paper copy of the M20K Illustrated Parts Catalog shows the Optional Equipment Group - Oxygen system. Attached is a file with the info that may assist you. The last page in the file (pg. 452) shows the effectivities symbols appropriate for your aircrafts serial number. Jeff M20K Oxygen System Parts Catalog.pdf

Do you or your AP/IA have a copy of the TCM TSIO360 maintenance and OH manual? IThere is a copy in the downloads section. Additional things worth checking are: 1) Fuel flow at max rated MP for your engine type - GB, LB? 2) Once FF is in the correct zone, perform a GAMI lean test flight to see what the FF spread is. Ideal would be no more than 0.5 gph spread. 2) Are the metal cylinder baffles installed correctly? 3) It looks like there is a lot of surface corrosion on the engine and induction tubes. You may have an induction leak as the seals between the tubes are off color and may be leaking. 4) At cooler OAT's and sea level the MP can easily overboost on the GB/LB engine. Has to be controlled by the pilot via throttle as earlier mentioned. 5) Overboost can destroy the lower end of the engine in short order. Consider draining the oil and check the filter for metal. Also a borescope can be put up thru the oil sump drain hole to look around for damage.

THANKS FOR SHARING

Happy New Years to all fellow Mooniacs ! 40 years of Mooney ownership: flying, hands on maintaining, upgrading and improving various aircraft, Mooneyspace has been an invaluable source of information. THANKS TO ALL !

My 1986 252 has a constant OV warning light illuminated at all times of operation. Has anyone run into this issue?

My IA and I made two plates to cover the oil cooler - one is ~ 1/3 and the other is ~ 1/2 of the surface. I believe the Mooney Weatherization Oil Cooler cover "Kit" is long gone MIA.

Three alternator failures in M20 K's - one the belt driven alternator tension bracket broke and the alternator shifted, broke wires and caused an electrical system failure - over a known airport, put gear down with hand cable system. The second one was due to an accessory case gear that sheared - third the alternator coupler failed. Current K has dual alternators!

Moonyspace has helped me work my way up to my forever 1986 252! I grew up maintaining/rebuilding motorcycles and automobiles. Then I discovered airplanes and couldn't stop wanting to work on them. As a student pilot in the early 1980's I helped the local FBO in Twin Falls, Idaho convert a Mooney from wood to metal wings. Seeing how the airframe was built, etc. I was hooked. I have rehabbed Mooney's G/E/231 and 262, and finally worked my was into my 252. You all on this forum have been an invaluable source of information and are keeping the Moony dream alive - THANK YOU!!!!!

There are a number of limitations on the RayJay turbo installation on the M20E. There is an article on the installation of that system on M20E written by Kerry McIntyre @ KNR Inc., Evanston, WY. Search his website for the list of his articles and it is in the May 2000 MAPA Log publication. Practically speaking any turbo aircraft has numerous advantages over their normally aspirated versions. I have flown routes similar to yours for 20 years as I am based at KGEG. I have utilized several Mooney models (E, G, J, and K) and found that the turbocharged K model is best suited in all aspects for the routes I fly. Feel free to PM me if you want any more additional information on your consideration. Jeff

Jeff Nichols @ Alta Avionics is a really sharp technician who can help you out. altaavionics.com.

My avionics installer is trying to find a copy of the DAC GDC31 GPSS roll steering AFMS/AFM document. It turns out the manufacturer has stopped making the unit and claims to not have that paperwork anymore. Go figure. Might anyone have a copy of this document? Jeff

Jeremy - thanks from all your Mooney brothers and sisters!

Thanks for the info. Interestingly, 20 years ago I owned a 1997 Encore and flew it from Idaho to the mid-west and east coast several times. It was measurably slower at cruise than the 1986 252 I currently fly. Perhaps due to the heaver weight with just 10 hp more. Still it is an awesome upgrade for those that like this size of a TC Mooney and who need to carry more weight. Too bad the managers at the factory couldn't see their way to produce a modernized Encore. "When if's and buts are nuts and candy, all the world will be fine and dandy"
