The FAA is accepting comments until August 16 on a proposed Airworthiness Directive that would affect as many as 3,572 TFE731-2 and -3 turbofans on U.S.-registered aircraft. If the measure is enacted, the engines’ low-pressure turbine stage 1 disks would have to be repetitively checked for fatigue cracks. An estimated 1,900 of those engines would require disk replacement under the proposed AD.
Gulfstream Aerospace, for the second year in a row, achieved the highest overall score for product support (pertaining to its original models), according to the results of an annual AIN survey of turbine business aircraft operators.

Honeywell TFE731 maintenance shops at Harrods Aviation in Farnborough, UK, and Sweden’s Volvo Aero have signed a service agreement combining their offerings. The result is a one-stop, heavy maintenance and overhaul team fully supporting the popular turbofan. Honeywell has designated Harrods’ engine shop a major service center, while Volvo Aero has offered heavy maintenance on the TFE731 Classic, -20, -40 and -60 variants.

Phoenix-based engine and avionics manufacturer Honeywell says its 10,000-pound-thrust engine contender is well under way. Ron Rich, the company’s director of advanced technologies, told AIN that parts for the company’s HTF10000 demonstrator have already been ordered, with the core engine expected to be operational by the end of next year.
Operators of jets powered by Honeywell TFE731 engines with digital electronic engine controls (DEECs) will be able to participate in the fault-code reporting service offered by Honeywell and Jet-Care beginning on June 1. The fault-code reporting service was announced in mid-2005, and Honeywell and Jet-Care have been preparing to launch the service since then.
Honeywell has delivered the first batch of 32 TFE731-50R engines destined for Hawker’s new 900XP midsize business jet. This latest version of the engine, derived from the TFE731-50 powering the Dassault Falcon 900DX, continues a series that began with certification of the first TFE731 in 1972. Since then more than 11,000 TFE731 engines have been built.
