"Top 25" Update - Global Customer Committees Nail RAILs

The Global Customer Committee (GCC) subcommittees at the Spring 2015 meetings in Phoenix were able to report several notable successes in both the Electrical and Mechanical areas.

Over the past five years the GCC has evolved from roots going back to the mid-1970s into a worldwide group with the mission of listening to customers and preventing problems from occurring through a free flowing exchange of information.

Working teams composed of industry channel partners collaborate directly with Honeywell on the highest priority items from a "Top 25" Rolling Action Item List (RAIL)—primarily through face-to-face meetings held twice a year in various global locations.

Among its successes this year, the Electrical group addressed and resolved a yaw damper disconnect problem. The yaw damper―a device used to reduce the rolling and yawing oscillations due to Dutch roll mode―had been disconnecting because of a software issue. Feedback from Atlas Aircraft Center helped prioritize a solution that is now available to Pilatus® PC-12 NG customers.

Another RAIL issue the GCC closed addressed the common complaint from line technicians that they have difficulty finding a particular Honeywell Service Information Letter (SIL) or Technical Newsletter to help in troubleshooting dataloading problems. GCC team members collaborated to combine all of the SIL references and tips/tricks into one single SIL.

When one of the newest Primus Epic loads was released with numerous undocumented Crew Alerting System (CAS) and maintenance messages, the GCC asked Honeywell to find the source of the errors and correct them for future certifications. As a result, Honeywell modified its internal release process to minimize these errors and at the same time created a tracking system for errors observed by operators in the field. This will improve the Central Maintenance Computer (CMC) fault reporting and diagnostic capability for future loads.

Meanwhile, the GCC Mechanical subcommittee closed RAILs by improving turbofan inspection criteria for Honeywell's AS907/HTF7000 turbofan engine compressor and impeller blades.

"Analysis of removed compressor components found that the allowable accept/reject criteria could be greatly expanded," said Mathew Williams, Product Support Engineer.

As a result, Honeywell expects to see a dramatic reduction in the reject rate during the scheduled 8,000 hour compressor inspections for aircraft affected by this RAIL item which include the Avro RJX, Bombardier® Challenger 300,  Bombardier®Challenger 350, Gulfstream® G280, Embraer Legacy 450 and Embraer®Legacy 500.

"By all reports, this was one of the of the better meetings we have had, with open dialogue and improved breakout sessions," said John Dano, Product Support Engineer.
