TDG Aerospace has introduced the Universal Fault Interrupter (UFI 3000), designed to prevent ignition sources resulting from arcing events in aircraft electrical systems.
A Petroleum Helicopters Bell 407 ditched into the Gulf of Mexico on August 16 after an apparent catastrophic engine failure. The pilot and a sole passenger escaped without injury after autorotating and deploying pop-out floats. The wreckage was recovered and a subsequent NTSB examination revealed “an uncontained engine failure near the third-stage turbine wheel” followed by the failure of the first-stage turbine wheel.
When Honeywell announced at last year’s NBAA Convention in Orlando its intention to build the HTF10000, a 10,000-pound-thrust turbofan engine for super-midsize to large business jets, its Tech 7000 engine demonstrator was in test with a variety of technologies running.
Cessna 208B Caravan, Globe, Ariz., July 22, 2005–The NTSB determined that the probable cause of the crash of Caravan N717BT was the fatigue failure of the compressor turbine stator vane, the liberation of vane material into the compressor turbine (damaging the turbine blades downstream) and the total loss of engine power.
A newly designed circuit board is now available for Citation 525 and a few Citation 560 operators that have been required since late last year to disengage their pitch trim and autopilot servo circuit breakers to prevent a possible runaway trim. The FAA has proposed mandatory replacement of the breakers, installation of which is covered under warranty for the Model 525.
Shirley, N.Y.-based Naasco Northeast Corp. (Booth No. 2238) recently received FAA approval for the overhaul and repair of Hartman A-1077 series relays, which are used on a variety of fixed- and rotary-wing aircraft and had previously been regarded as unrepairable.
A proposed AD calls for inspections to detect improperly installed wiring for optional cabin lighting that could cause fires in Falcon 50s. The FAA, which cited no incidents attributed to the alleged problem, said the wiring may be directly connected to the battery bus instead of through a dedicated circuit breaker.
Eaton Corp. (Stand A919) has developed a new oil indicator sensor that works with a rotary-wing aircraft’s existing chip detection system to accurately determine oil fluid levels in intermediate, tail rotor and main gearboxes. The system works with existing aircraft wiring and features a cockpit caution panel indicator that detects the presence of oil.
The Eldec division of Crane Aerospace & Electronics (Hall 4 Stand G20) is showing an example of what it reckons is the ideal means of reconciling a growing demand for more powerful on-board electrical equipment with new restrictions on the effect individual loads can have on the aircraft power supply.
“Let there be light,” said designers at DeCrane Aircraft’s Audio International, and to make it even better, they added full-spectrum color. The Little Rock, Ark.-based company’s Spectra 35 full-color, fully programmable LCD touch control switch is the first in the Spectra 20 Series, named in recognition of the company’s 20th anniversary in business.
