Get your Lycoming manuals here...

Someone on the Yahoo Lycoming forum (yep, there is one) posted this link. Not sure how long it will be there.

EDIT: The site is not very fast. Right click and select "Save link as... " rather than opening (slowly) in the browser then saving.

FYI - Looks like those where from 2007. Many of them have newer revisions. For the most current versions list for manuals see Lycoming Service Letter L114AY dated Sept 24, 2015.

Good point. These should be for reference only and were uploaded on 2007. Many are much older. If doing real engine work, the latest manual would be needed from Lycoming.
