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.

The FAA plans to adopt a new airworthiness directive for the Hawker Beechcraft King Air C90GTi. The AD is prompted by reports of incorrect gauge wires used in certain wiring bundles for the cockpit electrical power for backlighting and instrument panel components. The AD would require replacing incorrect gauge wires in certain electrical power wiring bundles, inspecting associated wiring bundles and components for heat damage, and taking the necessary corrective actions.

Turbomeca chairman and CEO Pierre Fabre knows that for his company to grow and prosper, it is not only necessary to sell engines to helicopter manufacturers that deliver all over the world but also to allow engines to be built in countries like China. But it is naïve to think, Fabre said, that there is no risk of losing control of intellectual property when engines are manufactured by non-Turbomeca-owned entities.

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.
