When it issued Eclipse 500 Airworthiness Directive 2008-24-07, which becomes effective today, the FAA asked for comments from operators. The AD limits the Eclipse 500 to a maximum pressure altitude of 37,000 feet due to “several incidents of engine surge” of the jet’s Pratt & Whitney Canada PW610F-A engines. The surge is due to carbon buildup on the static vane during high bleed flow conditions.

Soloy Aviation has received FAA certification for its Soloy 206 Turbine Mk II, a Cessna 206H re-engined with a 417-shp Rolls-Royce 250-B17F/2 turboprop engine and fitted with a Hartzell three-blade prop with full beta reverse features. According to the company, the Mk II can climb at 2,460 fpm at sea level, cruise at 20,000 feet at 213 ktas, carry 775 pounds with full fuel and has an approximately 550-nm range.

Is it a jet? Is it a turboprop? That’s the question that remains after Socata confirmed here yesterday that it is still pursuing a twin-engine aircraft to augment its product line beyond the TBM 850 turboprop single. Company officials were tight-lipped about details, other than saying that the aircraft, codenamed NTx (NT for New Twin), will be bigger, faster and have two more seats than a TBM 850.

A Jan. 20, 2007 incident over the English Channel resulted in the UK’s Air Accidents Investigation Branch (AAIB) recommending the FAA mandate operators adhere to a service bulletin Honeywell issued subsequently in late 2007. Falcon 900B G-HMEV had departed Farnborough en route to Tel Aviv. When the aircraft reached FL130 over the English Channel, there was a loud noise from the rear of the aircraft.

Despite a softening U.S. economy and soaring fuel prices, demand for business jets and turboprops is still surging, according to the first-half delivery report from the General Aviation Manufacturers Association (GAMA).

UK-based Rolls-Royce and GKN Aerospace have established a joint venture to study the use of composite materials in fan blades. The engine manufacturer and the aerostructure specialist are investing, on a 51-49 basis, £11 million ($22 million) in
a research and development program. For Rolls-Royce, this could signal a major shift from a well established design choice.

The quality of cabin air remains a concern for aircraft manufacturers in their quest to ensure the safety of crewmembers and passengers. Even small oil leaks have laid the groundwork for a disturbing sequence of events that too often figure in routine flight report summaries covering airliner and corporate aircraft crews and passengers.

I recently had the chance to fly one of the King Air C90s re-engined with two Walter M601E-11s, which are 751-shp engines flat rated to 550 shp for this installation. The airplane we were flying was N800RP, a 1974 King Air C90, S/N LJ-628. Dan Sigl, owner of Seagull Aviation, which is working on a conversion package for King Air 90s and 100s, agreed to bring the aircraft to my home base, Solberg Airport in New Jersey.

Rolls-Royce unveiled a new turboprop engine for general aviation applications on Tuesday at EAA AirVenture in Oshkosh, Wis. The RR500 turboprop engine is larger than the turboshaft RR300 launched last year and will deliver 350 to 450 shp. Based on the RR300 core, the RR500 features a higher mass flow compressor and correspondingly matching turbine, as well as an exhaust-down configuration, a gearbox and propeller controls.
