On 26 January 2017, an EASA Test Pilot carrying out certification test flying to extend the Dornier 328's maximum demonstrated crosswind was unable to retain control during an intended full stop landing on runway 09 at Sumburgh and it departed the side of the runway onto soft ground and stopped abruptly. The Investigation noted the Test Pilot's total type experience was the three circuits immediately prior to the excursion and attributed it to inappropriate flight control inputs and power lever movements. Intervention on the power levers by the aircraft commander had not been enough to prevent the excursion. AAIB Bulletin: 9/2017 D-CTRJ EW/G2017/01/11
