Yes, LOBO tracks these matters. Have you ever been to Oshkosh Airventu= re? These accidents are discussed in detail there. Based on your comments a= bout the engines you would be surprised. In many cases it was not the engin= e.

I agree, the pilot community lost another great guy. =A0Even if he was= a jerk, we still need to solve this riddle. =A0Is LOBO following up on eac= h of these crashes to learn what the experts determine to be the cause(s)? = =A0If not, we'll continue to be having these conversations until we eve= ntually run out of pilots, or airplanes.
