However, it may not be complete. I got the CD on the airplane I bought last summer and it made no mention of the nose wheel collapse which triggered the tailwheel conversion. It did mention the STC associated with the conversion, but not the incident. It's entirely possible that the incident was not reported.
I went on the Club's Mama file and looked up a 150 that I owned in the late 60s which I had to put in a pea patch and suffered major damage. No mention of that incident, and I did have a prayer session with the FAA GADO at Allentown PA.
Just don't count on the accuracy of those data bases, just check out the logs very carefully, and read between the lines. My airplane shows a propeller repair, with straightning and balancing, but no mention of any engine work. Fortunately, prior to the last major.
