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 performed a preflight inspection and departed to his destination. He stated that after a normal approach the left wing “dipped” at touchdown. The airplane subsequently “landed hard” on the left side. After the landing, the pilot shutdown the airplane and requested a company mechanic to inspect the landing gear. A visual examination of the landing gear was performed, but no damage was found. Subsequent examination of the airplane conducted three days later, revealed substantial damage to the fuselage, and left wing consistent with a hard landing. The airplane is also used for training, and it could not be determined if the airplane was flown after the hard landing. The pilot at the time of the hard landing, and the date and time of occurrence was undetermined.
