Piper PA-30 N7746Y accident near Tucson, Arizona

Probable cause

The pilot’s loss of control during landing for reasons that could not be determined based on the available evidence.

NTSB analysis

The pilot reported that, while on short final to land, the airplane yawed to the right. The pilot stated that full left rudder was needed to keep the airplane straight. The airplane subsequently touched down hard and departed the right side of the runway. All three landing gear collapsed and the left wing buckled, which resulted in substantial damage to the airplane.

A postaccident examination of the airplane and engines was conducted, including test runs of both engines. No anomalies were noted that would have precluded normal operation or contributed to the loss of control during landing. Engine data from the accident flight were recovered, and no anomalies were noted in the data. Thus, the reason for the pilot’s loss of control during landing could not be determined based on the available evidence for this investigation.
