Heinz Kohli, who in May 2003 was named CEO of Jet Aviation Group, abruptly decided to leave the company “effective immediately.” In revealing this development today, officials of the Zurich-based worldwide business aviation services conglomerate would not comment beyond saying, “Differences over the company’s future strategy” led Kohli to resign. Carl Hirschmann, son of the founder of Jet Aviation and the only member of the family to have a stake in the company and a seat on the board, will succeed Kohli on an interim basis. In October 2005, Jet Aviation was acquired by Permira, a European-headquartered private-equity group. The sale ended uncertainty over the fate of the Hirschmann-family-controlled enterprise, which had been informally in play since the family put it on the market in early 2002. Within three months of the acquisition, Jet Aviation acquired Midcoast Aviation from Sabreliner. Most recently the company dropped longstanding plans for an FBO in Kuwait. Jet Aviation officials declined to comment on the precise reasons for abandoning the project, saying only that it is now focusing future business development in Europe, Asia, South America and the U.S.
