I would sure would like to know why all of these "certified engines" are quitting on takeoff.  

Mark S. 

Maybe the engine driven fuel pump is failing.  We are running low boost continuously in case the engine pump fails and to address fuel pressure issues at altitude, hot fuel, vapor lock and other problems.  

I understand the engine will not make full power on low boost (reduce manifold pressure and settle for less power?)   

Or, it might quit if high boost is on and the mixture is not adjusted.   

Since engine driven pump failure, heat and altitude all affect fuel delivery, it would seem using the low boost continuously could solve or make these problems manageable.  

Dr. Lyle Koen did our last two physicals.  He was a very likeable guy who built one of the early IV’s and had over 1000 hours on it.  We talked to him about joining LOBO and coming to the Branson Fly-In. 

Given the more knowledgeable than usual witness account, could training have changed this outcome?
