“Welcome to Lear Jet Country,” a marketing slogan that attached itself to the early-20-series Lear Jet, is likely to be remembered only by industry old-timers who recall the airplane’s ability to take off and climb to 41,000 feet without effort.

Emergency AD 2003-08-52 was issued last month for the GE CT7-9B turboprop in response to 12 compressor-stall events in Saab 340Bs over a six-month period. The stalls occurred when pilots throttled back from takeoff power to climb power. Nine of the events involved engines that had the compressor variable geometry (VG) rigged to N1, one of two allowable rigging options that affords slightly higher performance at the expense of stall margin.

When Charles Lindbergh began planning one of the first truly long cross-country solo flights in 1927 everyone understood the risks inherent in a 3,000-mile journey in an airplane powered by a single 223-hp Wright J5 engine. Failure meant he’d probably end up as a shark snack. Luckily, he didn’t have the boss on board.
