IF found to be criminally negligent.
Unfortunately, Malaysia Airlines would certainly not be the only ones.
In addition, Asia, Africa, the Middle East, South America are scary. Primarily local flights.
Even U.S. Airline flights to some Pacific destinations are uncomfortable, mostly in the weird items those flights allow on some flights.
Nope, not just criminally negligent. Just negligent period - batteries not being replaced is pretty basic so far as aircraft maintenance.
