Saw this on Facebook a few minutes ago. For you manual junkies now is the time to go crazy. 
With the current COVID-19 crisis going on and stay-at-home orders in effect, I have decided to give complete and free access to Avialogs for three months. You can access, browse, download, thousand of aviation technical manuals, brochure and soon aviation books for free. The only requirement is to register on the site between April 4th and May 1st. Stay safe.
On Avialogs registration page:
Three months - Full and Free
- Three months full access
- Unlimited access to all manuals, brochures, and documents.
- Advanced document viewer (print, rotate, etc)
- Unlimited access to digital downloads for all manuals and documents (PDF documents).
I do not see anything about auto-renewal except for the 2 year plan. Would still recommend reading any fine print though.
