SYNOPSIS
The Pilot had conducted a general handling and aerobatics flight in the aircraft, a Stolp Starduster TOO SA-300 biplane, followed by a return to land on the westerly grass runway at Ballyboy Airfield, Co. Meath. During the landing roll, the left main undercarriage leg gradually collapsed, causing the aircraft to veer to the left. During the subsequent runway excursion, the aircraft impacted a perimeter fence adjacent to the runway and came to rest facing in a south-easterly direction. The Pilot and Passenger were both uninjured. There was no fire.
