Analysis

Approximately 1/2 mi from the arpt after takeoff, the plt noticed the left front baggage door partly open & made a left turn back toward the airstrip. After the turn, the baggage door came completely open, the left wing dropped immediately & the acft stalled. The plt added full power & lowered the nose. When he raised the nose near the ground, the acft shuddered & crashed. Two rescue personnel, both certificated pilots, arrived shortly after the accident & found the nose baggage door in the unlocked position with the bayonet pins retracted. A Piper representative stated that if the left side nose baggage door of a PA-31T opened in flt there would be the likelihood of an interruption to the smooth airflow through the prop, possibly reducing the thrust produced by the blades.
