Skydiving operators would like to carry as many people aloft for a single jump as possible—while observing the aircraft’s weight limits. However, the FAA has issued an important safety alert for pilots—20013—warning operators of a possibly overlooked hazard when using aircraft that are certified with two control wheels, such as single-engine Cessnas. In most skydiving airplanes, all seats are removed, except for the pilot’s, to make room for jumpers strapped in with bulky parachute gear. In order to make entry and exit from the airplane easier, some skydive operators remove the right side control wheel. Sometimes, operators also leave the protruding column to which the wheel was attached in place. This can pose a serious risk to a jumper sitting near the pilot.
