Boeing 737 Max

Boeing has shifted its 737 Max schedules to reflect first delivery of the Max 8 to Southwest Airlines in the third quarter of 2017, as early as six months ahead of the original plan, Boeing Commercial Airplanes vice president and general manager Scott Fancher revealed here in Paris yesterday. As a result, schedules for the Max 9 and Max 7 would also shift by at least a quarter. The company expects the program to reach firm design configuration in July. “The risks are understood, they’re being managed effectively and we have no serious technical issues to deal with,” said Fancher.

The 900ER STC should be approved next February. The split-scimitar winglet modifies the existing blended winglet with a new cap section, and adds a ventral strake.

Aerion

Aerion, which has been defining and refining its design for a supersonic business jet (SSBJ) for the past 11 years, is here at EBACE (Booth 7030) still quietly confident that it will someday be able to add the word “producer” to its résumé. To that end, a NASA F-15 has been flying this spring from Dryden Flight Research Center in California with an 80- by 40-inch section of Aerion airfoil attached to its belly.

A Gulfstream G650 set a city-pair speed record last month on a flight between Shanghai and Newark, N.J., flying the 6,855-nm route in 13 hours and 32 minutes, the Savannah, Ga.-based aircraft manufacturer announced yesterday. The jet took off from Shanghai Hongqiao International Airport on April 18 carrying five passengers and four crewmembers. ATC restrictions kept the G650 below FL310 for the first hour before it was cleared to climb to its normal cruising altitude of FL410 to FL510.

In a Service Bulletin issued May 3, winglet manufacturer Aviation Partners (API) instructed operators with winglet-equipped 800-series Hawkers modified by STC#ST01411SE to reduce maximum permissible altitude to 34,000 feet. “Several instances of aileron/wing oscillations have been reported on the Hawker 800 [series],” the company said. “Aviation Partners and the FAA consider this Service Bulletin to be a safety-related limitation until a design change to preclude the oscillations is developed and FAA approved.”
