Probable cause

Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot of the multi-engine, retractable landing gear airplane reported that, while on final approach to land, he allowed the airplane’s airspeed to decay. He attempted to regain airspeed by reducing his bank angle and pitching the nose down; however, the airplane landed hard and the left main landing gear collapsed. The airplane sustained substantial damage to the rudder. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
