pilot716 Posted February 15, 2011 Report Share Posted February 15, 2011 So the deposit is down and the pre-buy inspection will be in a day or so on an 83' M20J 201..It has a very well suited panel with all the bells and whistles we wanted, great mods and extra's. with 300 SMOH should we ask for a Boroscope of the engine or is the compression check and oil analysis good enough with a low time engine? we also have an extensive list from MAPA for the pre-buy inspection. I am almost there! Quote Link to comment Share on other sites More sharing options...
74657 Posted February 15, 2011 Report Share Posted February 15, 2011 If the 300 hours have been over the last 2-3 years then I would not worry about it. If it has been 15 years since the overhaul I would be a little nervous. Look at the logs and you will see how frequently the plane was used.

Piloto Posted February 15, 2011 Report Share Posted February 15, 2011 If the plane has not been washed recently check for the exhaust stain color on the belly. A yellowish-white stain is a good sign of no oil burning and good fuel mixture. A dark brown stain is an indication of some oil burning. Also check the bottom spark plugs. For 300hrs engine they should be dry with no oil on them. After landing idle the engine to 700rpm and verify oil pressure is in the middle of the greem arc. A lower reading is an indication of bearings wear. Fuel tank leaks mostly show with full tanks. Check for signs of old cleaned stains. They usually are light brown or light green. Remove the back seat floor carpet and check for corrosion along the bottom spar cap and tubing at the side panels. Check also the main spar stiffners corrosion at the wheel wells. Check numbers coloration of the air speed indicator. Yellowish color indicates the plane has been parked outside for several years. Planes not stored in hangars are subject to corrosion and fuel tank leaks. Most Mooney owners take very good care of their planes.

pilot716 Posted February 15, 2011 Author Report Share Posted February 15, 2011 Thanks, guys, all duly noted and will be used! Quote Link to comment Share on other sites More sharing options...
thinwing Posted February 15, 2011 Report Share Posted February 15, 2011 Do a function check of all those avionics in the panel...make sure everything is working,will pass a vor check..It is really easy to overlook this in all the excitement..a lot of mechanics just power stuff up on prepurchase and if the box lights up than say it checks out..kpc Quote Link to comment Share on other sites More sharing options...
pilot716 Posted February 15, 2011 Author Report Share Posted February 15, 2011 I flew the plane last week and made sure all avionics were working, traffic, A/P, etc..even did a waas approach on the KAP 150.. Quote Link to comment Share on other sites More sharing options...

thinwing Posted February 17, 2011 Report Share Posted February 17, 2011 very nice...that panel is very well equipped...the adf still works???kpc Quote Link to comment Share on other sites More sharing options...
pilot716 Posted February 17, 2011 Author Report Share Posted February 17, 2011 ADF works but is there for show as it will be taken out at some point and some new gadget will replace it! Thx Quote Link to comment Share on other sites More sharing options...
carusoam Posted February 17, 2011 Report Share Posted February 17, 2011 Mark, You may want to consider holding on to the ADF for one reason.... KMMU ILS requires ADF (FYI) - that was alphabet fun....

Cruiser Posted February 17, 2011 Report Share Posted February 17, 2011 Effective July 16, 1998, pilots may substitute IFR-certified GPS receivers for DME and ADF avionics for all operations except NDB approaches without a GPS overlay. GPS can be used in lieu of DME and ADF on all localizer-type approaches as well as VOR/DME approaches, including when charted NDB or DME transmitters are temporarily out of service.

carusoam Posted February 17, 2011 Report Share Posted February 17, 2011 Cruiser, I agree. It is necessary to keep the IFR GPS database up to date to stay on the up and up...If the database is old, using the ADF keeps it legal. For anyone not reading the approach plate: The hold after the missed, is an NDB, on the ILS at KMMU. -a- Quote Link to comment Share on other sites More sharing options...
pilot716 Posted February 18, 2011 Author Report Share Posted February 18, 2011 Thanks guys, Yes i know the chatham NDB very well, not only is it part of the ILS (not needed if GPS updated) but it is part of the newark 7 departure out of KLDJ. I never used the ADF for it(gps of course) but funny how those are still kicken! anyhow...financing is approved! pre-buy should commence today or tomorrow( im going to FL on vacation so I want to see it taken apart before I leave for the week) and if all is good it will roll into an annual. hopefully take delivery first week of March.
