Evidence is mounting for what? That cycles cause wear? These airplanes aren’t old even by that measure. If there is a problem here then it is the manufacturer’s.
SWA generates way more cycles than anyone. They fly a LOT LOT LOT. More flying means more exposure to risk and thus more incidents. Southwest’s safety record beats everyone in the business.
If you study this for a living then you KNOW that it is the RATE that matters, not the total number of incidents.
Windows fail. It happens. I’ve had three delaminations in my airplane type over my career. It had nothing to do with our maintenance. It was the manufacturing. Those windshields are no longer made and are being replaced on-condition by a better version fleetwide.
Agreed. SWA is known for happy staff - and that includes their maintenance workers. Happy/confident workers tend to not cut corners and actually look for ways to improve quality of work done, with better efficiencies in repairs and procedures that make sense.
Some points:
- Want to see an airline with lots of issues - then look at how they treat their maintenance teams.
- If they outsource the entire maintenance program, they don't really care about quality - it's another companies job (until there is an issue)
- Several large airlines are using foreign OVERSEAS maintenance providers with 'questionable' reporting requirements to the F.A.A..
- Eventually, you'll run into issues if you're constantly racing to the cost-control bottom at the expense of quality work at the risk of safety of your passengers.
- The job of almost all service providers is to do work for your customer, closest to the minimum specified in the service agreement to be as profitable as possible.
And I can guarantee you, those that outsource do a risk calculation on the cost savings of outsourcing their maintenance work verus in-house over a period of time against the payout they would face to families if they have a major incident. After all, it's about profit, not people.
