The breakdown in power supplies that caused serious disruption throughout India in late July has prompted the country’s government to draw up plans for using helicopters to support patrolling and restoring transmission lines. Government-owned Power Grid, which runs five separate electricity grids across India, is expected to issue requests for proposals for acquiring or leasing rotorcraft to be better prepared next time the grid fails or is damaged during an emergency such as an earthquake.
An airworthiness directive has been issued for all Honeywell TFE731-20R, -20AR, -20BR, -40, -40AR, -40R, -50R and -60 turbofan engines. It was prompted by a report of a quality escape of about 8,000 second-stage low-pressure turbine (LPT2) rotor blades manufactured by Honeywell’s Chihuahua, Mexico, manufacturing operation since 2009. This AD requires removing and inspecting certain LPT2 rotor blades. Cost of the fix is $3,480.
A proposed airworthiness directive for certain Cessna 525 air conditioning (A/C) compressor motors was prompted by reports of smoke and/or fire in the tailcone. The AD requires inspection of the number of hours on the A/C compressor hour meter, inspection of the logbook and replacement of the brushes or deactivation of the system until replacement of the brushes. When the brush wears down, the rivet in the brush contacts the commutator, causing sparks and excessive heat build-up within the motor assembly.
Aerospace and defense electronics suppliers in the U.S. are doing a better job of screening out counterfeit components coming mainly from China, and these gains will be reflected in more public cases of flagged parts, according to one electronics contract manufacturer. “You’re going to see incidences going up because we’re findng them,” said Robert Toppel, president of Axiom Electronics of Beaverton, Ore.
Emteq recently introduced two new aircraft cabin power products. The IntelliOutlet simplifies installation without need for an external ground-fault interrupter box, relay and circuit breaker. The IntelliUSB is a convenient power charging port for portable electronic devices that use USB charging and has built-in circuitry for 28-volt DC power, eliminating the need for a converter.
Daniels Manufacturing (Booth No. N2915), a manufacturer of tools for the high-reliability wire harness market, is introducing a new ratchet-controlled hand crimp tool at NBAA.
The FAA is proposing an airworthiness directive for the Bombardier CL-600-2B19 (CRJ) air-driven generator (ADG).
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.
As part of its €1.6 billion ($2.2 billion) Clean Sky joint technology initiative, Europe is undertaking a number of projects toward the development of more-electric helicopters.
A call for proposal released for Europe’s main aerospace research project, the €1.6 billion ($2.2 billion) Clean Sky joint technology initiative, has highlighted a strong focus on electric systems for helicopters.
