N144BY Mooney M20J

1977 Mooney "201" M20J

 Garmin IFR, Low Time Airframe and Engine

$127,000 USD

Here's a whole lot of performance, with a nearly new engine and nice avionics, for a great price.

The marketing department at Mooney called this the "Mooney 201" because it had a top speed of 201 mph, but officially this model is known as the M20J. The J model, powered by a fuel injected Lycoming IO-360, represents the M20 series as it was coming to maturity. Mooney incorporated performance mods into the J from the factory (ones that owners of earlier models must pay big money to have installed). Mooney also introduced a much improved panel layout for the J model. No other aircraft on the market compares to the efficiency, speed and value found in an M20J.

During my pre-engagement evaluation of N144BY, my immediate thought was that with a bit of cosmetic attention, this M20J would be absolutely attention-getting plus a well equipped aircraft that would be fun to own and operate. Its low time engine recently came out of Mena Aircraft Engines (a very reputable engine builder), and the aircraft has a respectable IFR instrument panel which includes a Garmin GNC355 GPS Navigator/COM and dual Garmin G5s.

Please carefully review the detailed, high resolution image gallery and lengthy walkaround video below, you'll see every inch of the aircraft. If you reach out to me, I can digitally share all logbooks and important documents.

Aircraft Evaluation

Exterior - 5/10 - The aluminum on the exterior of this M20J is in good condition - I observed no hangar rash on tips or trailing edges, just typical wear for an aircraft of this era. From a ways away, the aircraft looks good. A close up inspection reveals numerous paint issues. The paint is faded and is flaking off in some areas of the wing leading edges and on the horizontal stabilizer and elevator (most obvious on the underside of the elevator where the flaking is significant). There is one very minor ding on the vertical surface of the left side of the tail, close to the leading edge. And, there are some paint cracks around the engine cowling air inlets.  In the spirit of aesthetics, the aircraft is a good candidate for an eventual repaint, however it could continue to be flown "as is" without an issue. Please see the detailed high-resolution images below to better understand the flaws I am describing.

The windshield looks to be in good condition and not hazy. Side windows are also in good condition but show minor haze. The tires have lots of tread but show some signs of rubber cracking on the tread portion (not sidewalls).

Engine - The Western Skyways Gold Seal engine is one of the best available. The previous owner spent a lot of money to get one of these, but then after installing it, didn't fly the aircraft for several years. As is common in this scenario, internal engine parts start to show signs of corrosion/pitting due to lack of lubrication, and the unfortunate subsequent owner often is required to do the equivalent of an IRAN (Inspect and Repair As Necessary). That was the case with N144BY - not long after taking ownership, the current owner sent the low time engine out to Mena Aircraft Engines for rework. The engine came back refreshed, but shortly afterwards some metal was found in the oil analysis, so the engine went back again to Mena under warranty.

The engine has now been fully vetted by a professional engine shop, was recently reinstalled, and is in fantastic condition. The owner is actively flying the aircraft nowadays.

Panel - 8/10 One of the most expensive upgrades to an aircraft is avionics. N144BY already has a great panel setup: a Garmin GNC355 Touchscreen GPS Navigator and COM radio, a Garmin GFC500 2-axis autopilot, and dual G5 instruments to serve as Artificial Horizon (vacuum system eliminated) and HSI slaved to the autopilot. The most expensive and most important panel components are already here - all the panel needs is perhaps a little cosmetic TLC, and maybe a couple minor refreshes on other items, and this will be an outstanding IFR panel for a M20J.

Interior - 6.5/10 Replaced in 1987, the interior has supple leather seating that shows typical wear for its age. One minor nitpick is that there is small area to the lower inside portion of the passenger front seat where the leather shows excessive wear and tear, presumably from a seatbelt. The carpet, panels and headliner are in reasonable condition but show some age and could use a good deep cleaning to look a lot nicer! Please examine the high-resolution images in the Image Gallery below.

Overall - During the pre-listing inspection and the deep logbook/documentation review, no concerning issues were found, inside or out of the aircraft. The recent engine shop "clean bill of health" helps assure that the fuel-injected Lycoming IO-360 is fresh and ready for a long life. The panel is well on its way to being a fantastic setup. All I see that this aircraft could use is some cosmetic TLC, however it's perfectly good to go as-is. This M20J is a solid high-performance aircraft that is immediately ready for its next mission.
