Where is the IRS searchable history of reviewing the status of tax-exempt organizations?

Years ago, while doing a deep dive into not for profit regulation, specifically relating to 501(c)(7) social clubs, I came across a number of documents where the IRS published their reviews of various organizations.

Within those documents was the review and revocation of tax exempt status of a flying club and the reasons behind it. There was another one where the IRS reviewed another flying club, and upheld their tax exempt status, and provided the reasons.

As I am currently affiliated with a flying club, it's in my interest to help keep it on the straight and narrow, and recently there's been issues with some people looking at the regs and trying to loosely interpret them.

I want to provide actual cases showing that the IRS doesn't play that game, that wordplay doesn't work, and that many of the recent ideas proposed will run afoul of regulation.

Much appreciated!
