Boeing issues alert due to 787 engine fire switch failures
Boeing has issued an alert to airlines using its flagship B787 Dreamliner, warning that the switch used to extinguish an engine fire has failed in a “small number” of instances. The switch also severs the fuel supply and the hydraulic fluid to prevent flames spreading.In its alert to airlines, Boeing warns that long-term heating can cause the fire switch to stick in the locked position so it can’t be used to release the two fire extinguishers in each engine. The FAA has issued an airworthiness… (www.theguardian.com) Más...Sort type: [Top] [Newest]
How much could this switch possibly cost? Is there any quality control left at Boeing?
The switch in question in part number 010-2310445-70. It's cost $1147.83 according to Boeing's ERP system. The price of the switch is $1521.60 if you purchase it as a spare part and your customer record shows you to be part of the "AL2330" customer segmentation within their customer hierarchy. Yes, Boeing is entitled to make this relatively small profit on the switch. Also, yes, Boeing has a world-class quality control system. Please do a little research on manufacturing quality control before asking such inane questions. Boeing products are among the best aircraft mankind has ever produced, based upon their stellar safety record. Now please go back to be whipped up by the news media, you sheep.
How does the switch suffer long term heating?
Aircraft switch panels are complex electronic components. You might be surprised at how much heat is generated simply by resistance (look it up, if you don't believe me). Additionally, aircraft switch panels are often installed in locations with very tight clearance tolerances (a reality of the manufacturing engineering work involved in making design engineer's wishes into actual products). These tight tolerances coupled with electronic resistance can easily make these switches subject to "long-term heating", especially over the expected life-span of a passenger airliner.

Yes, id10t, corporations are in business to make money for their shareholders. Are you enjoying a booming economy? Of course you are, so shut up and do your job, which hopefully will never be flying passengers anywhere, you socialist jerk.
