Embraer’s quest for a complete business jet portfolio took a major step forward in March with the start of taxi tests of Legacy 500 serial number 001 at the Brazilian OEM’s São Jose dos Campos plant.

The FAA has issued a notice of proposed rulemaking for an Airworthiness Directive for certain Embraer Phenom 300s. It is based on an unsafe condition as a result of an inadequate number of drain holes in the primary control surfaces (rudder, elevators and ailerons), which may allow water to accumulate in the control surfaces.
The Embraer Legacy 500 development program has recently achieved “several significant milestones” as the fly-by-wire midsize business jet gears up for its first flight in the third quarter, the Brazilian aircraft manufacturer said today. Milestones include taxi runs and the beginning of ground vibration tests on the first Legacy prototype, as well as developments in the second and third prototypes. Concurrently, the joint definition phase has started for its smaller sibling, the Legacy 450.
Russian Helicopters is redeveloping the Kazan Ansat light twin with conventional flight controls, as opposed to the fly-by-wire (FBW) system with which it has been flying thus far. Kazan Helicopters has performed the first demonstration flight with a hydro-mechanical flight control system.
The testing program, which involves two prototypes for flight and ground tests, started last year. The manufacturer has filed an application with the Interstate Aviation Committee’s Air Registry for additional type certification, which it expects to achieve in the second half of this year.
Boeing engineers appear to have kept themselves busy refining the design of the 737 Max since the company announced its intention to re-engine the ubiquitous 737NG with CFM Leap-1B turbofans.
The first flight of Embraer’s new Legacy 500 has been delayed until the third quarter of this year, due to software problems with its fly-by-wire controls. Nonetheless, the 500 and its shorter-haul, smaller sibling, the Legacy 450, are set to shine as the latest entries in the Brazilian manufacturer’s burgeoning book of business jet offerings, which range from the entry-level Phenom 100 to the uber barge Lineage 1000.
“Birdbrain…” It’s more an insult to our feathered brethren than to the human deemed short on intellect.
The Dassault Falcon 7X fleet has accumulated more than 100,000 flight hours, marking a significant milestone for the French aircraft manufacturer’s 5,950-nm, large-cabin business jet. It delivered the first 7X in June 2007, and since that time 133 of the trijets have entered service in 31 countries. According to Dassault, the 7X fleet leader has accumulated more than 3,500 flight hours.
Erickson Air-Crane and Stilwell Baker Inc. (SBI) have jointly developed and certified a modernized automatic flight control system (AFCS) for the Sikorsky S-64F heavy-lift helicopter, using an unusual reversal of the all-digital approach to avionics. Erickson has contracted with SBI for the latter to supply production AFCS hardware to equp the 16 S-64s in the Erickson fleet.
Embraer’s next new business jet, the fly-by-wire Legacy 500, rolled out of the manufacturer’s São José dos Campos headquarters in Brazil on Dec. 23, 2011. The jet’s first flight had been planned by the end of last year, but has been delayed until the third quarter this year due to a software problem with the fly-by-wire flight control system’s remote electronic unit made by Parker Aerospace, according to Embraer.
