Misshapen and misaligned rivet holes in parts of the fuselage removed from a Southwest Airlines 737-300 has lent more credence to theories that a manufacturing flaw led to the eventual failure of the lap joint during an April 1 accident in which a five-foot-long tear developed in the roof of the airplane while en route from Phoenix to Sacramento. A rapid depressurization occurred at 34,000 feet, forcing the crew to divert to Yuma, Ariz.

Hawker Beechcraft is accelerating Hawker 400XPR development by adding a second aircraft to the test program. Slated for certification next year, the 400XPR offers improved range and airfield performance compared with the temporarily suspended 400XP, while reducing noise and emissions by replacing the existing engines with new Williams FJ44-4A-32 turbofans.

A bilateral project between NASA and German aerospace research center DLR is expected to focus on the role rotor tip vortices play in helicopter noise by recording vortex velocity fields and rotor-blade deformations by using a test stand with a variety of high-speed cameras, lasers and LEDs that will make the vortices visible. Eventually research will progress to actual helicopters.
