Scan your 337 field approvals easily

You can help contribute to the Knowledge Base without writing anything!

It's been very handy to keep some examples of stamped 337 field approvals in our knowledge base for those submitting for follow-ons.

Example here for the Skywagon tires section.

So if you have any juicy ones in your logbooks, you can easily share them with BCP to post in the Knowledge Base under that aircraft's modifications section.

Here's how:

1. Install Microsoft Lens for iOS or Android (my tutorial is Android):

Image

2. Lay your documents on a dark background like your wife's nice placemats. Hover your phone as normal as possible (camera looking straight down) above the page. Portrait mode is best. Watch the orange outline as it detects the page edges in real time. Move the phone camera slightly until the orange outline envelops the entire page.

Image

3. Hold steady and snap the pic

Image

4. Don't tap the orange checkmark button yet. Tap the "new page" button.

Image

5. Flip your 337 over or to the next page.

Image

6. After you've shot the 2nd page, now you can tap the orange checkmark "Done" button.

Image

7. It's going to ask you what you'd like to name the file and what you want to do with it. Name it something intelligent, then select the checkbox only for PDF. Tap the Save button.

Image

8. Now it's time to send it to old Zane by email. The exact details of this step may vary between iOS and Android, but here's how on the Android version: Click the 3-dot menu on the document thumbnail. A menu pops up below. Choose "Share."

Image

Image

9. It will present you with the various sharing methods. Select your mail app and send to [email protected]

Done!

Obviously there are some privacy issues with sharing a document with your N# and your A&P IA's certificate number on it. To have the document serve as follow-on data, I think we need those numbers to be valid. If you just want to give people text for reference, let me know and I will redact those details before publishing on BCP.

Did this sail over heads? Or are you all thumbing through your logbooks for useful field approvals? 8)

Would LSTCs help at all Zzz? That's about all us Canafians can really offer, but I do have a few of them available. As well as a couple letters from TC that I've been using as approved data for a couple specific installs.

If you guys have a similar process where example field approvals count as precedent, sure. I was under the impression TC didn't grant FAs?

Yes that's right, no field approvals. But we have limited supplemental type certificates (LSTC) that are tied to one specific airplane. It helps to provide one if you are trying to get one for another. Anither option is a letter that is from TC granting use of something proven, which makes it approved data and doesn't require a STC. Those are very rare, but they do happen from time to time. I have one specifically referencing a certain propeller installation on a C175 that makes quite a performance difference.

Re: Scan your 337 field approvals easily

The app I’ve been using for stuff like this in iOS is called “Cam Scanner”, and it is slick. Take a pic in the app, and it improves lighting, etc to make a document more readable.

Slick!

The notes app on any iPhone lets you scan a document with total ease. Literally just point and click and it perfectly crops the scan and finds the edges of the document.

Re: Scan your 337 field approvals easily

The really valuable 337's are the ones dated 10/1/1955 or earlier. If anyone has any good ones in their aircraft records these are the really good ones to share.

These old 337's can be used directly as approved data for current field approvals.

See FAA AC 43-210, chapter 2, 201(a)(7)
