SPECIAL INVESTIGATION REPORT: PIPER AIRCRAFT CORPORATION PA-46 MALIBU/MIRAGE ACCIDENTS/INCIDENT, MAY 31, 1989 TO MARCH 17, 1991

Between May 31, 1989, and March 17, 1991, five fatal accidents occurred in the United States involving Piper Aircraft Corporation model PA-46 airplanes. Twelve persons died in the accidents and the five airplanes were destroyed. The National Transportation Safety Board investigations and analyses of the accidents disclosed that one occurred because the pilot entered a very strong thunderstorm, lost control of the airplane, and overstressed critical structural components, which separated in flight. The causes of the other four accidents involved probable failure to use pitot heat during flight in freezing instrument meteorological conditions, possible misuse of integrated flight guidance and control systems, loss of control, and in-flight airframe failures due to loads and stresses that substantially exceeded design limits. The Safety Board issued six safety recommendations to the Federal Aviation Administration related to more stringent pilot training requirements for pilots of small pressurized airplanes, the addition of a pitot heat operating light in PA-46 and similar airplanes, revision of checklists in the pilot operating handbook and the airplane flight manual for PA-46 and similar airplanes, and improved training material for integrated flight guidance and control systems.
