Looking at both the TCDS files on the FAA web site, and Journeys, there were only 2 versions of the KR-21, the -21 (or -21A) and the -21B. The KR-21...

Times have changed in the last couple years. Read FAA Order 8100.19. ...

There is always the truth to the saying “ it doesn’t matter if you are talking antique cars, boats, trucks, motorcycles or airplanes, buy the very...

Charlie, you are confusing Field Approvals with STCs. For Field Approvals, there is minimal engineering rigor applied, just kind of eyeball...

Web, you have to remember that there never has been a regulation that allowed Field Approvals. They have always been policy only, and there in lies...

I’d be curious to see that paper trail. Was it on a KR-21, or a different model in the KR series. Sent from my iPad using Tapatalk

If you are referring to J3C airplanes, TC691 allows 80HP on a J3C-65. You can’t exceed that based on the fuel quantity unless you put additional fuel...

If you go to item B.5 (page 10) of this document http://fsims.faa.gov/wdocs/other/major_repair_alteration_job-aid.pdf You will se where it comes...

Sure you can go Experimental, but likely not Amateur Built. You might get Exhibition, but recognize the limitations of that certificate. 91.319 says...

Charlie, perhaps nothing ground breaking with regards to the engine swap, but FAA policies have changed over time. The current policy is that you can...

First thing I would do is actually pull the FAA records. If it is still registered, you should be golden. If the registration was canceled, be...

Think about buying a car, the day it leaves the dealers lot, it takes a huge depreciation hit, then the value declines much more slowly as it is...

There was a request for the Fairchild 45 drawings, and Fairchild Industries (no real relationship to Fairchild aircraft) claimed the Type...

When you use Aero Bulletin 7 or 7a, you will also need Aero Bulletin 26 as that is constantly referenced in 7a. If you aren’t making changes, not...

KR-21 would likely be an Aero Bulletin 7 or 7a airplane. Long before the Civil Air Regulations. Changing from the K-5 of either 90 hp or 100 hp to a...

A good inspector should be able to give you an idea of overall condition, but there are areas that you cant see without removing the fabric. I would...

Just a quick look at the number of ADs issued on a given design can be a clue to the robustness of the design. Compare either PA-18s, PA-20s, and...

With cotton, you could expect anywhere between 5 and 15 years. At that time, the fabric would come off and all the underlying structure would be...

DavePA11, yeah, I know lots of banks want paperwork. The last airplane I purchased that had a bank loan was back in 1996. No sales agreement was...

As an A&P, I would never sign off on a pre buy inspection. For starters, there is no such thing legally. The FAA only recognizes Annual Inspections,...

When Ceconite came out in the early 60s, it was advertised as Lifetime Fabric.

Registration does not include the “X”, that is only permitted to be displayed per 14CFR45.22. I’m surprised that the GDL-82 let you input an NX as...

But it does include the unique ICAO address which is linked directly with the N#, and from there it is a simple search on the FAA web site to get to...

There is nothing in 91.225 that says ADSB equipment can’t be removed once installed. Any equipment (except that required by 91.205 for the condition...

Clean engine with solvent, dry it thoroughly. Thanked baby powder and lightly coat the entire engine. Run 5 minutes and look for wet spots on the...

Just to be sure your fuselage fittings are properly located, I would measure from centerline of fuselage to center of each bolt hole, and then also...

It’s really pretty simple, min sink speed is Vx, best glide is Vy. That being said, best glide will never result in going the farthest distance. For...

Saw pretty much the same thing on a C85 last year, looks like standard pistons in oversized cylinders. Sent from my iPad using Tapatalk
