NTSB Report said:At 10:46:45, the approach controller directed the pilot to turn to a heading of 160 degrees to intercept the localizer approach course for runway 16. At 10:47:15, the approach controller advise the pilot he was over the initial approach fix "Junoe", and to maintain 4,600 feet until established on the localizer, cleared instrument landing system (ILS) runway 16 approach.
That's part of why I think he was disoriented, really losing touch with all his instruments. He may have been fixated on those he claimed were failed. As a result, he could have relaxed his climb rate, disorientation progressed until he lost control.Did you notice he was reporting climbing through 3300, and about a minute later he is told to "climb, climb", but a minute and a half later the impact is at an altitude of 2800? Even at 500/minute he should have been at least at 4000 by then and with the urgency of the situation a full power climb should have got him to the 5100 he was assigned. I wonder who was at the controls the last few minutes, with the commercial pilot in the right seat.
