The FAA plans to clarify, but not change, its Part 25.1329h design considerations for manufacturers of aircraft low-speed alerting and protection devices.

During hearings on December 11, National Transportation Safety Board officials described the final approach sequence of Asiana Airlines Flight 214, which crashed at San Francisco International Airport on July 6. The Boeing 777 was cleared for a visual approach to Runway 28 Left where, as per a Notam, the glideslope was inactive.

In an online forum, a professional pilot wondered whether he might be incorrectly controlling the aircraft when he performed a slip on final approach because the airspeed always increased, not decreased as he’d been taught. Slips in transport aircraft are sometimes restricted or even prohibited, making it hard for pilots to know how to handle them when they are required.

The FAA is adopting a new airworthiness directive for certain Bombardier CL600-2B16s (CL601-3A, CL601-3R, and CL604 variants). It was prompted by reports of airspeed mismatch between the pilot’s and copilot’s airspeed indicators during or after heavy rain. The AD requires inspecting for drain bottles having certain part numbers and replacing affected drain bottles.

Shown in flight above Edwards AFB, with the test side visible, is Aerion’s phase-two test article mounted under a NASA F-15B.

Reno, Nev.-based Aerion is releasing results from recent flight tests of a natural laminar flow (NLF) wing test article this week here in Las Vegas, while the company continues to work to have its supersonic business jet enter service in 2020. The goal of these tests was to measure “real-world robustness” of supersonic NLF, which is a key technology for the Aerion SSBJ, in regards to surface quality and manufacturing tolerances.

Two crewmembers and five passengers aboard a Sikorsky S-92 operated in IMC by Cougar Helicopters were only 38 feet above the waters of the Atlantic Ocean when the pilot, having suffered a bout of spatial disorientation, regained control of the helicopter, according to a September 12 report from Canada’s Transportation Safety Board. The incident occurred on July 23, 2011, 217 miles southeast of St. John’s, Newfoundland.

In the UK AAIB’s second update on the investigation into the August 23 Eurocopter AS332L2 Super Puma fatal accident, it appears the helicopter was “intact,” with “both engines delivering power,” when it struck the sea. The attitude was near level pitch with a slight right bank.

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.
