Had one in almost a brand new Seneca 4 Twin a few years back. Both engines had covered 100 hrs. I was at Grosse weight on an above standard day.
The takeoff was normal until at 200 feet in the climb there was a serious vibration and yaw.
I estimated the bad engine was still producing some power maybe 30-40 percent and equally realised that if I feathered and shut it down i would go one way and one way only DOWN.
I kept the thing going one hand poised on the prop lever in case there was a big bang
Once up at circuit hight I levelled and then shut the engine down as by then it was a bag of nails.
Continental examined the unit and eventually admitted over torque of the rocker shafts at manufacture which had resulted in three rocker shafts shearing. They replaced the unit with a complete brand new engine within days.
Initially they claimed over boost on takeoff but luckely for me a PAX had filmed the complete takeoff with all the relevant engine instruments visible and well within limits.
Now I question the training for engine failure in light twins and wonder whether a pitch for level flight isnt a better option even a few hundred feet up.
Tony congrats on pulling off a good landing in a limited area
