I guess the pilot of the EC 130 did the best to his abilities to prevent a major catastrophe.
Honestly, I live by the adage " no matter how the aircraft looks like after an emergency landing, the most important aspect is to walk away without having sustained serious injury or harmed anybody else". In case of the alleged engine failure on Hawaii; hope the pilot did analyze the condition correctly, and did not get fooled by a malfunctioning instruments or else.
