Accident at Shellharbour

[UTW]

Here’s another theory…

• In some older Piper aircraft (including Cherokee Six, Lance, Saratoga, PA-28, and PA-32 variants), the seat-track locking mechanism or rear seat retention pin assembly could fail to engage properly.
• When that happens, the seat can slide suddenly rearward under acceleration — particularly during take-off roll or initial climb when power is applied and G-forces act rearward.
• The sudden motion can cause the pilot to lose reach of the controls, often leading to a pitch-up and/or loss of control.
