It’s finally time (cowling)

Working on fitting the lower cowling. I expected to have an issue with the carb air box and that is a definite need to redesign. The much more sloped cowling is going to require a new lower profile carb air box. What I didn’t expect was an issue with the landing light. I found that the O-360 muffler hits it. I now understand why as the difference with the fuel injected O-360’s moves the muffler down and aft. O-360 is up and forward due to the carb. I will have to move the landing light to the center on the carbureted Mooneys. I’m also thinking I will need to move one of the air fittings on the muffler shroud. I did manage to get it on today and do some initial fitting to verify if I’ll have any other issues.

Really solid work David! I cannot wait to see the install completed. Looks as if it may make the legacy birds look as modern as any Mooney.

Very nice!  What is the squarish inset area?  Are you doing louvered cooling there?  Apologies if it’s been previously discussed.

While your guess is as good as mine, I am thinking the squarish things on the side are perhaps where access doors might go.  Any other guesses before we get the real answer from the man?

Those will be maintenance access panels on both sides. It will also be able to have louvers added in the future by just switching out the panel if needed say for a turbo’d Mooney.

Fitting continues with cutting open the access panel openings and trial fitting a cowl flap. Biggest challenge is designing a new carb air box to fit. I have an idea that if it fits will make it fairly easy and cost effective. Going to make it out of wood to test my theory.

I'm very happy to see that you put the access panels back on both sides! Makes it so much easier to change the oil! As a 13-year C owner, I've only dropped the lower cowling twice, and my A&P did it once working on the carb.

One of my most favorite aircraft activities....... dropping the lower cowling on a C, E or F ! :angry:

I lost count the number of times my cowlings have been on and off !

Excellent idea.  I hate dropping the bottom cowling.

No turning back now. Final fit to drill for the firewall camlocs under way. Also fit the new prototype carb air box for the C & G models. Minor adjustment to clear the cowling found during initial fit but looks like this will work well. Also fit the plug to the prop hub for the forward bulkhead to make the carbon fiber spinner. Making some progress.
