Mooney N1937Y

Time to part with my M20E

This 145 knot 10 gal/hour airplane commuted me to the bay area and San Diego, along with trips to Seattle, many places in Oregon, Phoenix, Colorado Springs, Dallas, Kalispell, Sedona, Santa Fe, Death Valley, Mammoth Mt, Winter Park, Las Vegas, Provo, Canyon de Chelly, Winslow, Page, Roswell, Boise, and now to a broker in Oklahoma City. Sherri Sturgill 405-812-2525 and Brian Sturgill 405 923-0525 will be handling the sale.

My Mooney N1937Y, hangared at KTRK, owned and flown only by me for 21 years amassing 1800 hours. Before that AP/IA/FBO 15 year owner for personal use and commecial rating sign offs. Before that private owner in Oregon, and ???. .

Annuals at Lasar 2011, 2010, 2009, 2008, 2007, 2004, 2003, 2000

Annuals at TopGun 2002

Some people seem to think every service bulletin is logged every annual. Actually only ADs are logged every annual. So has this or that SB been performed, yes to 208 (Lasar), 217 (every annual the belly panels come off and check for spar an other cracks). So for the 120 some SBs on the M20E planes, if anyone is aware of the SBs it is Lasar or Top Gun, the Mooney experts in CA. Did I do all my annuals at Lasar or TopGun, no when I was commuting to the bay area Lasar was convenient, as most times I could drop the plane off and get a ride down and back in a bay area Mooney coming or going for annual (30 minute flight).

In the 90s most annuals were done at Todd Aero in Truckee. Todd Aero owned the plane before I did, and most of these were owner (me) assisted. 2012 to the present Sierra Aero at KTRK did my annuals. Why, well it's just down the ramp from my hanger, and Jeff who founded Sierra Aero, worked for Bob Todd and did many annuals back in the 90s on my airplane.

So to illustrate below is a picture of 4 log books, 3 notebooks of maintenance work orders, and FAA CD of N1937Y records. Which do you think has more information?

Scan of the Aircraft logbooks




Yes some of the PDFs are hard to read, so here are pictures of the logbooks -- caution can be very large

Aircraft Logbook 1 - 221 MB

Aircraft Logbook 2 - 257 MB

Aircraft Logbook 3 - 93 MB

Engine Logbook - 77 MB

Recent AD Compliance Reports


I have these going back to the 90s, if you really need to see them I can scan those as well.

Tannis heater engaged - I recommend it even in summer.

Panel closeups

panel left console glare shields compass -- yes it is required in the airplane, but you are in a world of hurt if your GPS, your tablet and phone all died. Avare is great on all my portables, and it even has ADS-B in.(though a bit primative GUI)

All panel instruments working. Except the altimeter working for VFR flight, but is outside acceptable adjustment range for IFR.

And the ugly

I found out in the last week that N1937Y was involved in an incident in 1966, and I have not got the full details, but apparently the left wing was damaged and repaired. If you look at the logbooks it was reported in March 1967 as "Repairs to aircraft per Gulf Coast airworthiness repair order 66-807 completed this date. Aircraft airworthy" signed... Not much to go on.

While I had the seats recovered during the 2010 painting, these interior parts (side panels, headliner, carpet) are original and have not been replaced -- good job for Airtex. My emphasis has ALWAYS been on operation as a airplane. My wife knows she did not marry a metrosexual, so I would have gotten to these someday, but... looking at new airplane.

As for WAAS you can either pay Garmin a bunch to upgrade, or pull the 530 and put in a drop in replacement from Avidyne.
