You'd think even a giant like Boeing would have heeded a warning in 2011 when Cessna CJ4's were grounded by the FAA.
"In 2011, the Federal Aviation Administration temporarily grounded the CJ4 and issued an airworthiness directive because of battery fires in the Lithium-Ion original equipment:
We are adopting a new airworthiness directive (AD) for certain Cessna Aircraft Company (Cessna) Model 525C airplanes. This emergency AD was sent previously to all known U.S. owners and operators of these airplanes. This AD requires replacing certain lithium-ion batteries installed as the main aircraft battery with either a Ni-Cad or a lead acid battery. This AD was prompted by a report of a battery fire that resulted after an energized ground power unit was connected to one of the affected airplanes equipped with a lithium-ion battery as the main aircraft battery. We are issuing this AD to correct the unsafe condition on these products."
