True, but more heat does increase the chances of failure. So why should I accept higher temperatures when I can come up with a solution that runs much cooler?
Watch it on take-off (or at rotation, as pilots say) when the wings get loaded. They bow upwards a whole lot. But that's meant to be. However, the same goes here: The more flex you design in the faster fatigue can set in. For airplanes the time frames are usually in excess of 30 years. Come to think of it, same for electronics. Some aircraft are more prone to structural failures than others. The worst one out here (California) was a CDF plane where both wing struts gave up after decades of service. Unfortunately the crew did not survive that. The other (larger) accident of a jetliner was more likely due to maintenance issues. With that one the threads for the stabilizer screw gear head had stripped out.
AD is an excellent company IMHO. I trust them and they have never disappointed that trust. Can't say that for some other companies. But there are some parts with every manufacturer where I feel a bit uneasy and decide to go another way.
