Another Possibility
Since these were both brand new aircraft (200 hours for one, and ferry delivery for the other), I thought of another possibility.
Many years ago now, I knew of a concept in electronics known as "infant mortality". The idea was that brand new electronics experience a higher failure rate than equipment that is still new, but has been in service for several weeks or months. Similarly, sometimes new owners of brand new (just delivered) autos sometimes have to sort out problems before the autos perform correctly.
In the airline business, do you guys experience similar issues where you sometimes have to sort out a brand new just delivered aircraft? I'm not talking about sorting out a brand new model just introduced, but rather sorting out a brand new line aircraft of an existing model, where the existing model has basically been sorted out.
Could any brand new aircraft issues, have contributed in any way to this accident?
