Just before his accident, George McHenry removed his modified Lycoming O-230, about 110hp, and installed an O-320, 150hp. He was testing it when the incident took place. I spoke with him just days before to discuss my installation of an O-290 130hp (I'm taking extra precaution with CG, etc.). George was very knowledgeable and helpful. He will be missed.
