N7790YPiper PA-30 · 1965

The pilot of the personal flight stated that he was the flying pilot and was seated in the right pilot seat with a passenger rated pilot seated in the left pilot seat. The pilot stated during landing that perhaps the airplane bounced. The airplane was right of the runway centerline and not pointed down the runway. The pilot stated that he corrected to the left and the airplane skidded off the runway and into a dirt area. The airplane’s left main landing gear collapsed, and the airplane sustained substantial damage that included damage to the left wing.

Automatic Dependent Surveillance-Broadcast data showed that the airplane crossed the runway approach end with a ground speed of approximately 113 kts during calm wind conditions. The airplane’s ground speed was approximately 70 kts about 4,000 ft down the runway when it began to veer off the runway. The Piper Aircraft PA-30 Owner’s Handbook states that the final approach speed for the airplane is 100 mph (86.9 kts). The bounce during landing was consistent with an excessive touchdown speed after a final approach flown at a speed higher than that specified for the airplane.

The pilot stated that was no mechanical malfunction/failure of the airplane that would have precluded normal airplane operation.
