Has the FAA been bringing the pain super fast lately? Last week we saw hundreds of cancellations on American Airlines and Delta Airlines flights because of potential issues with wiring harnesses underneath the aircraft. The issue was solely on their MD-80 aircraft, each carrier grounded a few flights, checked out the problem and everything got rolling again. What caused the inspections, however, was a flag raised by the FAA questioning the methodology of the inspections, not dissimilar to warnings raised earlier on Southwest 737s.
Now, United Airlines has discovered that one of the tests to check the fire suppression systems in their Boeing 777 cargo holds hasn’t been run properly, so they’re cycling all of those aircraft in to make inspections. Thirty one of the eighty four scheduled flights in total were canceled.
Why the sudden spate of aircraft groundings for maintenance checks? It might have to do with increased attention to aircraft maintenance issues as a result of the Southwest incident a few weeks back. Airlines are now probably scrambling to double and triple check their records to make sure that everything is up to snuff as the FAA and congress clamp down on quality.
A congressional hearing on the matter is scheduled for Thursday, at which point we’ll probably hear much more on United and maintenance checks in general, and what our fair politicians plan to do to keep things running smoothly. We’ll let you know how that goes.
