Eaton Aerospace (Hall 2B Stand D32) comes to Paris celebrating its centenary–100 years in which it has grown from a small axle business into a company with, among other things, one of the most impressive arrays of aerospace systems and components, and an annual turnover of $13.7 billion.
The FAA issued a draft policy memorandum that would change circuit-breaker layouts in aircraft electrical systems, as well as how pilots deal with tripped circuit breakers. Comments are due by September 12. Principal changes would be for manufacturers to group and identify essential and non-essential circuit breakers in Part 23 aircraft and to publish flight manual guidance about when to reset circuit breakers.
The FAA has issued a draft policy memorandum that seeks to change attitudes about circuit breaker use in electrical systems and how pilots deal with popped circuit breakers. The policy would affect aircraft manufacturers and modification providers. Comments are due by September 12.
As part of its initiative to combat the problems associated with aging aircraft, the FAA has funded a suite of projects at the University of Dayton Research Institute (UDRI) that includes self-healing wires, smart clamps and radio wire fault detectors. The goal of the project is to eliminate the time-consuming task of tracing wire faults.
Irvine, Calif.-based Eaton Corp. (Booth No. 5967) recently celebrated the successful flight testing of its arc fault circuit breaker (AFCB) technology as a stand-alone replacement for existing circuit breakers. Completing more than 350 normal service flights aboard a U.S.
After three years of development and testing, Safe Flight Instrument’s “Powerline Detector” system for helicopters received FAA supplemental type certificate approval last month. The approval applies to the White Plains, N.Y.-based company’s own Aerospatiale Gazelle, and STCs for other helicopters will be sought as customer needs dictate.
TDG Aerospace has introduced the Universal Fault Interrupter (UFI 3000), designed to prevent ignition sources resulting from arcing events in aircraft electrical systems.
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.
Some three-and-a-half years ago, Safe Flight Instrument of White Plains, N.Y., received supplemental type certification for its Powerline Detection System (PDS) on the company’s own Aerospatiale SA341G Gazelle. Since then the Safe Flight system has been certified and installed on Eurocopter AS 350s, EC 135s and AS 365s and Mil Mi-17s flying in Australia, Korea, Russia, South Africa, Switzerland and the U.S.
Controversy continues to swirl around the FAA’s September 2005 aircraft thermal and acoustic insulation regulations, which went into effect in January. The agency amended the original regulations after discovering that the wording implicated a much broader range of components than intended.
