The latter is a sad story, I knew the pilot. I was surprised to read that the misfitting of the component was seen as the only probable cause.
I had been led to believe the plane had stood outside during a very rainy night and was known to be sensitive to rain water being ingested in the fuel tanks.
Many people close to the accident believed the cause of the engine failure could easily have been due to water contamination.
Either way, flaws were found in maintenance procedures so this outcome should make aviation safer.
