It's a shame that they just got this bird airworthy last year. Most of the TBM Avenger guys seem to agree that a split cylinder was the culprit of the mechanical failure based on the sound the engine was making before the ditching. Pilot did a great job getting the plane down. Really a textbook ditching. LeRoy Grumman really knew his stuff when it came to carrier aircraft. He knew landing in the water was always a possibility, and pretty much every Grumman designed for carrier ops had good ditching characteristics.
Avengers are very straightforward aircraft, much like working on cars from the same era. Just like how LeRoy Grumman knew he had to design a plane to ditch correctly, he also built a plane that was easy to maintain, and more importantly, repair after receiving battle damage. There's no doubt this plane could certainly fly again. The "X" factor is how much money is it going to take.
