Duncan Aviation recently received FAA approval and Honeywell authorization to perform major periodic inspections (MPIs) on the TFE731-20/40/60 turbofan engine. The Lincoln, Neb., company has for more than 20 years been a Honeywell-authorized major service center providing MPIs on the TFE731-2/3/4/5 engines.

Stevens Aviation’s Dayton, Ohio facility and Jet Aviation’s Bedford, Mass. facility have been designated by Raytheon Aircraft as service centers for the entry-level Premier I. The approval covers heavy and scheduled maintenance, airframe maintenance and engine repairs. There are approximately 25 Premier Is in the field since deliveries started last June.
The FAA, EASA and Brazil’s aviation authority have approved a new maintenance program for the Embraer ERJ 145, allowing operators to increase C-check intervals from 4,000 flight hours to 5,000 hours. Embraer claims this extension, along with other recent efforts to lower maintenance costs, will cut maintenance workloads by 13 percent.
A special airworthiness information bulletin recommends that operators of Mitsubishi MU-2Bs comply with recently issued service bulletins (SBs) for a one-time inspection to check for corrosion and the proper torque of wing attach barrel nuts and bolts. The SBs were based on the discovery of a fractured barrel nut during a routine inspection.
Du Pont has introduced a wiping product that the diversified industrial company said is designed exclusively for aircraft windshields and passenger windows. Made from a proprietary blend of fibers, the company said its Sontara window wipes are intended to be used with approved cleaning solutions (such as Prist and Aviation Laboratory) on acrylic, polycarbonate and glass transparencies.
Operators waiting for the long-delayed certification of the Orenda V8 turbocharged piston engine retrofit for the King Air C90 will have to wait a little longer. Orenda officials in Nova Scotia told AIN that the engine installation kit is being redesigned with the aim of making it more “maintenance friendly.” The company is now aiming for an STC by year-end.
AvAero, a maker of Learjet hush kits, has received an STC for a fuel-saving aerodynamic modification of the Boeing 737-200/300. The company claims the mod will decrease the twinjet’s fuel burn by an average of 4 percent, equating to about a 230-pph fuel-burn reduction. By repositioning the trailing-edge flaps, AvAero said it increases aft wing camber, which lets the airfoil generate the same lift at a lower angle of attack.
It’s not exactly the “Holy Grail,” but for business aviation operators and those whose job it is to install aircraft interiors, it’s close. What they’ve been so diligently seeking is a system that integrates all the various cabin electronics–lighting, audio-video equipment and communication systems–into a single, user- friendly, reliable and easily maintained unit.
At a ceremony last month marking the delivery of a newly overhauled Dash 8 to Honolulu-based Island Air, ExelTech announced that it secured C$7 million in new contracts this year from five regional airlines from as far afield as French Guyana to perform heavy maintenance at its facilities in Montreal.
To demonstrate the feasibility of a major restructuring of its aircraft cabin-completion process, Bombardier recently delivered the first Challenger 604 to be outfitted by the Canadian airframer in Montreal, where the airplane is built.
