A job well done to everyone involved!!!
Not trying to be the AAIB on this but it has been reported to the public as a double engine failure, the first thing that sprung to my mind was maybe a fuel selector issue with it having tip tanks (Please excuse i am not 100% sure on the fuel system of a PA30 ). Fuel icing may have been the issue but would it not of shown earlier in the flight. A friend of mine down south who has a PA30 (with out tip-tanks) who i contacted to make sure they werent involved came out with when i mentioned it was reportedly a double engine failure that it may of had ice blocking the tank vents which he said can be common on this type.
At least the pilot lives to fly another day and tell the tale.
Once again thumbs up to all that assisted the speedy recovery!!!!
