The head of the Boeing Co.’s troubled 737 jet program will retire from the company in the coming weeks. Eric Lindblad, who has led the 737 program for less than 12 months — brought in last year to lead it when the company's biggest concern was ironing out supply chain issues — will depart after 34 years with Boeing. Those concerns were soon overshadowed, however, by two deadly crashes of the jet in five months. The CEO of Boeing Commercial Airplanes, Kevin McAllister, notified employees of the change in a memo provided to the WBJ by the company following initial media reports Wednesday afternoon. “I have admired Eric’s resolve and drive, and we are grateful for his service and dedication,” McAllister said, adding that Lindblad had already expressed a desire to retire last year. The 737 MAX, Boeing’s (NYSE: BA) fastest-selling aircraft ever, has been grounded since the middle of March. Lindblad will be succeeded as the head of the 737 program by Mark Jenks, who had previously been leading the company’s development efforts of a potential new mid-market airplane (NMA).
