April 9, 2012 - Harry Zeisloft, who was one of EAA's longest-serving board members and an integral part of EAA's effort to create the auto fuel Supplemental Type Certificate (STC), passed away Sunday, April 1, in Mesa, Arizona. He was 93. Zeisloft served on the EAA board of directors for 40 years - from 1957 to 1997 - and also served on the EAA Aviation Foundation board from 1972 until 1996.
He became project manager of EAA's auto fuel STC project after retiring as a General Motors engineer in 1980. He moved to Oshkosh to take over the project full time, working with a Cessna 150 owned by EAA and flown by Jim Barton, in conjunction with EAA aircraft maintenance staff. Zeisloft's research and leadership allowed EAA to succeed in its six-year effort in August 1982, when then-FAA Administrator Lynn Helms announced at the EAA Fly-In Convention at Oshkosh that the Cessna 150 was approved to fly using auto fuel through EAA's STC program.
Zeisloft, a University of Iowa graduate, was an accomplished engineer throughout his career prior to his work at EAA. He earned 25 patents for aircraft and automotive innovations while at Bendix Corporation, Aeronca, and GM. Those patents include the automotive cruise control, anti-lock brakes, aviation fuel systems, and other advancements.
Private family services were planned.
