There is an extremely long debate over this one on Kathryn’s Report going in circles with at least one anon posting long diatribes repeating the same argument, laced with a lot of vitriol for the 152 pilot’s instructor, and there are camps where the 340 is definitely at fault and his estate will be gutted to the 152 is definitely at fault and
his estate will be gutted, to it’s all the FAA’s fault for having confusing rules. This last point is valid. Does the 152 have right of way because he’s at a lower altitude and is in an established pattern? Or does the twin have right of way because he’s on final?
Something nobody disagrees with is that both pilots, knowing a conflict was developing, could have avoided this if they’d taken action sooner, but both waited too long.
My take is the 152 pilot was too inexperienced therefore lacked judgment and was kind of stuck in his touch and go routine, along with having no idea the twin was approaching so fast (until the last few seconds). The twin pilot was either determined to “own” the runway because he had the right of way (in his mind) or he was having a medical event which might explain his extreme speed and lack of being in landing configuration.
