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.
