The FAA is adopting a new airworthiness directive for the Bombardier CL-600-1A11. It requires revising the airplane flight manual to prohibit thrust reverser operation. The AD also calls for repetitive detailed inspections of both engine thrust reversers for cracks and modifying them if necessary. Modifying the thrust reversers is also an optional terminating action for the repetitive inspections.

United Turbine Parts (UTP) lays claim to being the world’s leading independent supplier of Pratt & Whitney Canada PW100 and PT6 engines and components. With Latin America having a growing fleet of aircraft powered by these turbine engines, the region is an important growth market for the U.S. company.

Airbus C295

Airbus Defence & Space announced a repeat order from Egypt for eight more C295 transports, and one from Brazil for three C295s configured for search-and-rescue. The company will be offering C295s with a winglet option beginning next year, although it did not say whether the newly ordered aircraft would be so configured. Airbus has received orders from 19 countries for more than 140 C295s.

The General Aviation Joint Steering Committee Safety Assessment Team (SAT) is recommending the use of angle-of-attack indicators for general aviation aircraft. The recommendation emerged from a recently completed study of 2,472 accidents that occurred between 2001 and 2010. The SAT determined that the use of AoA-based systems by the GA community is an effective method for reducing loss-of-control accidents in the approach and landing phase of flight.

SafeFlight AoA sensor

Safe Flight invented the stall warning horn in 1946, and refined the concept with its “lift transducer” beginning in 1953. Now the company is at EAA AirVenture 2014 with a new product–the SCx Leading Edge AoA (angle of attack) indicator. It’s priced to be competitive with other AoA indicators, especially considering its $200 show discount. AirVenture buyers will pay $1,295 when they buy a system at the Safe Flight booth (No. 18). The regular price is still-attractive at $1,495.

The pilot of an MBB-Kawasaki (Eurocopter) BK117B2 flying a trauma recovery mission at 5,000 feet agl in South Australia last year saw a number of hydraulic fluctuations on the helicopter’s system indicators just before the aircraft experienced an uncommanded and violent pitch up. That excursion was followed closely by a left roll and descent, according to the Australian Transport Safety Bureau (ATSB).

Clean Sky (Hall 4 Stand B10), Europe’s aerospace research venture, is exhibiting a model of a modified Airbus A340 with so-called “laminar flow” on an outboard section of the wings. The technology, if applied to the entire wing, could bring a 5-10 percent improvement in fuel burn. The A340 testbed is scheduled to fly next year.

The Engine Alliance, a 50-50 joint venture of GE and Pratt & Whitney, has received EASA approval for two new thrust ratings for the GP7200 turbofan engine, one of the two engines available to power the Airbus A380. The new ratings bring the GP7200 to four thrust rating configurations.

The Bauhaus Luftfahrt aerospace think-tank in May unveiled a concept for a “propulsive fuselage” aircraft, opening a new possibility for fuel burn reduction. It is part of a European Union-funded project in cooperation with a number of research centers, as well as MTU Aero Engines and Airbus Group Innovations (OE13). The latter company is also studying a hybrid-power regional airliner with Rolls-Royce (Hall 4 Stand H3). Meanwhile, it is flying a hybrid-lift quadcopter demonstrator for unmanned military and civil missions, the Quadcruiser.

Aerostar (Hall 3 Stand B31) has become one of the first independent European MRO organizations to install Split Scimitar winglets on Boeing 737-800s. The work was carried out for Sweden’s TUIFly Nordic at Aerostar’s Bacau facility in Romania, which is also the location of its headquarters. The winglets were fitted to two 737 aircraft, one arriving in early May and having the work done during a maintenance check, while the other followed shortly afterwards for a maintenance check, wing strengthening and installation of winglets.
