For instance, I don't remember paragraph 61.51(e)(iii) at all from way back when I studied it to determine when I could log PIC time. I'm fairly certain that it has been added since then (actually, there was no sport pilot license back then so I know that it has at least been changed), but I would like to know when it was changed and what the changes were.

At the bottom of the reg, it includes this:

[Doc. No. 25910, 62 FR 16298, Apr. 4, 1997; Amdt. 61-103, 62 FR 40897, July 30, 1997; Amdt. 61-104, 63 FR 20286, Apr. 23, 1998; Amdt. 61-110, 69 FR 44865, July 27, 2004; Amdt. 61-124, 74 FR 42549, Aug. 21, 2009; Amdt. 61-128, 76 FR 54105, Aug. 31, 2011]

This tells me when it was amended, but not what was amended.

Does the FAA make that information available?


Changes to federal aviation regulations are listed on the FAA’s Regulatory & Guidance Library (RGL) at http://rgl.faa.gov/:

  • From the home page, click on the database titled "Code of Federal Regulations"
  • On the left, in the navigation tree, select one of the branches under "Historical CFR" (for example, "By Part")
  • On the right, expand the items leading to the regulation that you are looking for (in this case Part 61)
  • Scroll down to the regulation that you are looking for (61.51) and it will list the original version and all of the revisions:

61.51 revision history

Each revision is a link which takes you to the regulation as of that version, with links to the NPRM's and dockets so that you can see what has been changed!

You can find this information with a bit of digging.

Hit up the GPO (Government Printing Office) here.

Choose the date range you want to look up.

Then choose the Title of the CFR you want (Aviation stuff is Title 14 CFR), and drill down until you find the Part you want, and it will give you some meta data about the change, and then the actual text of the change.

There might be an easier way, but, it is the federal government, so maybe not. :)

To answer your specific question, here is the link. (Click on the "Text" link for full details)

  • $\begingroup$ The only drawback here is you need to know the date range you're interested in - there's no way (I can find) to say "Show me all the changes to 14CFR91", and nothing like the "black line" indicating changes in the paper FAR/AIM from ASA. This is the one-and-only thing I miss about the paper version. $\endgroup$ – voretaq7 Dec 27 '13 at 3:16
  • $\begingroup$ @voretaq7 Well, you can get the specific date of the change from the quote that I posted above (which is at the bottom of every regulation on ecfr.gov). $\endgroup$ – Lnafziger Dec 27 '13 at 3:21
  • $\begingroup$ @Canuk I'll look at this a little more closely, but the link that you posted was for a change to 61.58, and not 61.51. $\endgroup$ – Lnafziger Dec 27 '13 at 3:22
  • $\begingroup$ @lnafziger Yes, I suppose you could look up each change listed in the amendment list. But dangit we're pilots - we're supposed to be lazy and spoiled and have automation to do this sort of thing for me while someone slips us coffee through a pass-thru in the armored door! :-) $\endgroup$ – voretaq7 Dec 27 '13 at 3:24
  • $\begingroup$ @Inafziger, I had written up this big thing and then realized I didn't specifically answer your question! So I looked up the last change mentioned on 61.51, but I guess I got the wrong one still! So, I guess you have to really want it! :) $\endgroup$ – Canuk Dec 27 '13 at 3:27
