That deflated feeling
During his preflight inspection of his Jabiru UL-450 prior to flying from Darley Moor to Cromer, the pilot noticed that both main tyres appeared to be slightly underinflated, so he increased their pressures. Takeoff and en route flight were uneventful, but as the aircraft touched down at Cromer it immediately turned left and skidded sideways, causing the nose and right undercarriage legs to collapse. Pilot and passenger were not injured. The left tyre was found to be deflated and there were grooves in the runway caused by the wheel and brake assembly. The pilot believes that, following inflation of the tyres before takeoff, the left tyre’s valve had not fully sealed, allowing air to leak slowly away.
