## Probable cause

The pilot's failure to properly flare the airplane during landing, which resulted in a hard landing and separation of the main landing gear. Contributing to the accident was the improper installation and over torquing of the landing gear attachment hardware, which reduced the load-carrying capacity of the landing gear clamping brackets.

## Findings

NTSB's coded findings; those marked are part of the probable cause.

## Analysis

The pilot/owner of the amateur-built airplane reported that, while performing touch-and-go landings, he failed to properly flare the airplane resulting in a hard landing. The landing loads exceeded the strength of the main landing gear attachment, which resulted in a separation of the main landing gear. The airplane subsequently departed the left side of the runway and struck the visual approach slope indicator lights, resulting in substantial damage to the right wing strut. The pilot/owner’s postaccident examination revealed that the aftermarket landing gear installation had been improperly installed. The attachment bolts had been overtorqued which preloaded and overstressed the hardware, reducing the load-carrying capability. The stripped attachment bolts allowed the clamping brackets to separate under load. The hard landing exceeded the reduced capacity of the landing gear attachment, resulting in a separation of the landing gear and a subsequent runway excursion.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
