Maybe retuning defective Lithium Ion batteries under warranty?
That's how the airtruck industry keeps the crews in high regard.
Strange that allegedly the UK Royal Mail will not accept Li-Ion batteries for despatch, as I found out online when trying to source one for my geriatric I-pod.
Are the airfreight companies still shipping these bombs around, even when notac'd and documented and supposedly correctly packed?
Just a thought from a former SLF airframe manager.........................
