Obviously, even an "antiquated design with a single point of failure", gets an air worthiness certificate by the FAA. However, LFP batteries need a fault-tolerant battery management system and tons of testing called out in UL1973 3rd edition. Not all aircraft need single-fault tolerance.
I suspect that a large majority of aircraft incident reports are a result of pilot error, nothing to do with the aircraft its avionics.

The National Transportation Safety Board, which investigated the crash, said Thursday that a single component of a critical flight control system failed, causing an unrecoverable, near-vertical descent. "The Mutiny Bay accident is an incredibly painful reminder that a single point of failure can lead to catastrophe in our skies," NTSB Chair Jennifer Homendy said in a news release. Nate Bingham, who is representing the Ludwigs' families, said the plane crashed because of "an antiquated design with a single point of failure."

Best regards, Rich Boats from the U.S. Coast Guard and Kitsap County Sheriff's Office search the area off Whidbey Island north of Seattle on Sept. 5, 2022, where a chartered floatplane crashed the day before, killing 10 people.
