Bob_Belville Posted March 28, 2014 Report Posted March 28, 2014 It may be the Lasar belly. A-M references installing Lasar kits. Quote

HRM Posted March 28, 2014 Author Report Posted March 28, 2014 The one piece belly pan with skid runners is made by Air Mods, Inc of Wheat Ridge, Co. The paper work says: weight change add 10 lbs to aircraft empty weight with no change in moment. It can be used on Mooney models: M 20 C, D, E, F, G, J, and K. The Supplemental Type Certificate number is SA4080NM. The Air Mods that owns the STC is not any of the "Air Mods" you guys are discussing. Quote

In fact the one piece belly on my E is the "One piece fiberglass belly pan fairing with skid runners by Aero Mod Inc, STC SA4080NM" which a prior owner installed in 1997! I shoulda knowed better.

PLN_FXR Posted March 28, 2014 Report Posted March 28, 2014 I've installed LASAR pans; would be interested to know how the Air Mods pan fits once you get her installed. Quote
HRM Posted March 28, 2014 Author Report Posted March 28, 2014 I've installed LASAR pans; would be interested to know how the Air Mods pan fits once you get her installed. My understanding is that all that is required is some cutting of existing metal and the installation of floating nutplates to hold the panel on. Quote

Yes - but I'd like to know how it fits; i.e., does it conform nicely to the compound curvature of your belly, of does it develop "gaposis" between fasteners? Quote

HRM Posted March 29, 2014 Author Report Posted March 29, 2014 Mine is 17 years old. ...and looks damn good for her age! Show me a woman who isn't sagging in a few places after 50 years and I'll show you a heckuva lot of plastic surgery work! (I'm safe, my wife never comes here...) 1 Quote
Hank Posted March 29, 2014 Report Posted March 29, 2014 My belly has no runner down the middle, is not white like that and less edge rippling. It is not a perfect fit, but it does well. Fifty two screws to remove and reinstall. I recommend the snazzy double-ratchet screwdriver from Lowes, that ratchets while turning in both directions. Makes screws go faster. Quote
aaronk25 Posted March 29, 2014 Report Posted March 29, 2014 I love mine the runners saved the airplane when it was landed gear up. We actually were able to reuse the existing one piece belly, although the runners are 1/4" shorter as the fiberglass was left behind over about 200 feet on runway 36 at Lansing IL. We were able to just reseal the runners with fiberglass. Very nice addition to any mooney. Quote

I have a couple of inexpensive power screw drivers, one is only 4V,a Ryobe from Home Depot. http://www.homedepot.com/p/Ryobi-TEK4-4-Volt-Screwdriver-HP53LK/202351930 I didn't expect much when I bought the 1st one but they are great. The torque is adjustable, they're light to hold up while laying on my back, and they're much easier on the screws than the big DeWalts. Quote

The torque is adjustable, they're light to hold up while laying on my back, and they're much easier on the screws than the big DeWalts. But I've grown to like my Popeye forearms! The previous owner(s) and A&P's apparently used power drivers on the belly, I had a difficult first two annuals. Then I started replacing screws and making sure everything went in straight [no more crossed threads, jammed screws and buggered up Phillips slots!], and now it's much easier. I just wish they'd used shorter screws, there's no reason to engage the threads with ½" exposed when you're screwing into nutplates. Most of them would be fine at ¼" long. Quote

Hank, my light weight, light duty driver is easier to keep straight than a hand tool and I back off on the clutch to keep from overtightening. When I got the plane back from the prop strike I found that 4 cowl nutplates around the spinner which are a size smaller than the rest had been boogered. No doubt the mechanic didn't notice the difference. All it took to fix was a turn or two with the right size tap. I keep a tap & die set and cutting oil in the hanger. Having a Mooney involves a lot of screwing around. Quote
