AAIB investigation to Percival P66 Pembroke C Mk 1, G-BNPH
Runway excursion, MOD St Athan, 7 July 2014.
After a normal landing, the aircraft drifted towards the left side of the runway. In an attempt to arrest this drift, the pilot used asymmetric braking which caused the aircraft to yaw rapidly right and depart the paved runway surface. The brakes on this aircraft are sensitive when used asymmetrically and the pilot inadvertently applied more braking force than he intended.
