My understanding with help from google.
Significant shortcomings in maintenance, management and parts inventory. Exfoliation corrosion in floor/wing attach area. Had cylinders salvaged from 1941 wreck? Engine two/three new cam discs found with damage, same in sister ships. Fuel/oil lines 30 years old!
Poor condition how ever, not related to the accident.
Quite correct, cappt!
The intermediate report contains some more interesting details. Temperature was ISA + 16 and all engines were delivering power. The report from the accident investigation branch is not only rather damning for operator and maintenance, but also for the oversight of the Swiss Federal Office of Civil Aviation. They (FOCA) claim they could not have seen all the rotten stuff. Well, looking for instance at the picture of the fuel lines, its difficult to imagine that even a brief inspection could overlook that. Inspections nowadays are all about forms, stamps and signatures, the hardware only gets a brief glimpse. Not helpful is also the fact that operator, maintenance and engine repairs are all controlled by the same persons. And the boss now claims that the corrosion set in only after the accident.....
