Overview
On 27 August 2013 at 1520 UTC, a privately operated Piper PA-18-150 (Modified) Super Cub, registration G-BJIV, sustained damage following a landing gear collapse at Sutton Bank Airfield, Yorkshire. The sole occupant, the pilot, was uninjured.
Pre-flight Maintenance
During the daily inspection prior to glider towing, the right front bolt securing the landing gear suspension arm was found to be bent. The aircraft was considered safe to fly pending replacement of the bolts, which was completed at approximately 1330 hrs. The aircraft was subsequently flown until 1645 hrs, when it was refuelled and a different pilot began the next session of glider tows.
Accident Details
Returning from a glider tow, the pilot landed on Runway 20 at a speed of 60 knots in nil wind conditions. During the ground roll, the aircraft hit a small bump and became airborne briefly before landing again in a manner the pilot described as not a heavy landing. The right landing gear partially collapsed due to failure of an attachment bracket, causing the aircraft to slew to the right. While still in motion, the pilot shut down the engine and electrical systems. Subsequently, the aircraft encountered a rut that completed the collapse of the right gear, followed by the left gear.
Damage and Subsequent Findings
The aircraft sustained damage to the landing gear, propeller, cowling, and left wing. The pilot reported that several cracked components were found in the landing gear structure after the accident; however, it is not known whether this damage was pre-existing or a result of the gear collapse.
Aircraft and Pilot Information
The aircraft, a 1965 Piper PA-18-150 Super Cub (serial no: 18-8262), was powered by one Lycoming O-360-A3A piston engine. The pilot, aged 59, held a National Private Pilot’s Licence and had accumulated 645 flight hours, with 154 hours on type. In the preceding 90 days, he had flown 22 hours, including 4 hours in the last 28 days.
