For many years, a small company named Lam Aviation has showcased its variable-geometry wing design at EAA AirVenture. Company founder Lawrence Lam (who passed away in 2010) even designed and built his own low-wing, retractable gear, single-engine airplane–the Wanderer–to demonstrate the concept and flew that airplane to Oshkosh three times.
The Australian Transport Safety Bureau has found the two pilots of a QantasLink Bombardier Dash 8-300 to be primarily responsible for an unstabilized approach that activated the twin turboprop’s stick shaker on final approach to Runway 16 Left at Sydney Airport [YSSY] in New South Wales in March 2011. The Bureau said both pilots got behind the required checklist duties for configuring the aircraft before commencing the approach.
The National Research Council of Canada (NRC) has commissioned a wind tunnel to help aircraft manufacturers measure the noise levels generated by aircraft landing gear. Industry historically has focused on measuring and reducing the noise generated only by engines.
There’s no better way to start off an EAA AirVenture show in Oshkosh, Wis., with a little flying out of the world’s busiest airport (during the week-long show, at least). Last year, the Gobosh folks were kind enough to invite me to fly the Gobosh 700A Light Sport Aircraft (LSA). This year, Remos Aircraft is demonstrating its newest LSA, the GX NXT, a high-wing composite two-seater powered by a 100-hp Rotax 912ULS.
Sikorsky Innovations has completed wind-tunnel testing of an active rotor system equipped with “high-authority” flaps, paving the way for what it says will be improvements in noise, vibration–and, marginally, efficiency–on future rotorcraft.
Mitsubishi MU-2B-60, Elyria, Ohio, Jan 18, 2010–The turboprop twin was destroyed and its ATP-rated pilot and three passengers were killed when it crashed on approach to Lorain County Regional Airport. The Part 91 flight departed Gainesville Regional Airport in Florida. After a missed approach, ATC cleared the aircraft for landing on Runway 7.
Bombardier CL-600-2B16, Vineyard Haven, Mass., Sept. 27, 2009–The Challenger was substantially damaged during a hard landing at Martha’s Vineyard Airport at the end of a Part 91 flight from Denver. According to the crew, the landing was performed with 30 degrees of flap in a 24-knot crosswind with an approach speed of 135 knots.
Early operators of Embraer’s $8.14 million Phenom 300 light jet are praising the aircraft’s speed, fuel efficiency, range and short landing distances, but they say it still has some teething issues that need to be resolved with regard to spurious crew alerting system (CAS) messages, full flaps, cabin seating and lavatory lighting. Embraer delivered the first U.S.-based Phenom 300 on December 31.
Boeing has completed major assembly of the first set of wings for the 747-8 Freighter, the company announced today. The 135-foot, 3-inch wings–thicker and wider than those they replace on the 747-400–incorporate new aerodynamics and allowances for different pressure distribution and bending moments.
Embraer is paying for a service bulletin to replace flap-controller units in the first 10 to 20 Phenom 100 very light jets. The new controller units will have updated software to fix a “nuisance failure” problem that causes the flaps not to work. “The failure does not actually exist,” explained Embraer’s Mauricio Martins de Almeida Filho, “but the system interprets it as a ‘flap fail’ condition and triggers a fail-safe shutdown.
