Just an aside. Not really answering your question,but a few years back....
A RFDS (Royal Flying Doctors Service) PC-12 single engine Turbine, PT6 powered, suffered a lightning strike outside Alice Springs in Australia. It returned safely to base with partial power. The Engine was a right-off though. I dont know if there was a ASTB report on it, but it would be interesting too see what happened inside th engine R.E. the failure.
It in itself proves that when dealing with forces of nature lightning is unpredictable and the damage it can cause undefinable. So what systems or engine problems that could occur is unknown you just hope that all the bonding straps and earth shunt etc are serviceable. That is all Aircraft Types. When you dealing with Millions of volts causing huge potential differences damage come sin all forms.
Iknow a PC-12 is far from a Commercial Airliner, but they do have basic EFIS and FMC systems on board.
Food for thought
