Probable cause

The failure of both pilots to maintain aircraft control while conducting training maneuvers at an altitude that precluded a safe recovery.

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Analysis

Prior to departure witnesses heard the pilots discussing the possibility of conducting pilot training. Less than 6 minutes after takeoff the airplane was observed in a dive to ground impact. The sound of the engine(s) was changing. The left engine magneto switch was found in the off position. Teardown examinations of both engines did not reveal any discrepancies. The other pilot held a commercial certificate with airplane single and multi-engine land, instrument, and flight instructor (airplane single-engine) ratings.
