AAIB investigation to Cessna 525A, N525DT

Runway excursion on landing, Gloucestershire Airport, 17 May 2017.

Summary:

The aircraft completed an ILS/DME approach to Runway 27 at Gloucestershire Airfield. The pilot reported the weather to be raining with broken clouds at 500 ft, a temperature of 13°C, 5,000 m visibility, and negligible wind. A runway inspection conducted approximately 5 minutes prior to the incident indicated that the runway surface state was wet with water patches.

After landing the pilot reported that the aircraft brakes were inoperative. He steered the aircraft off the runway to a clear grassy area on the right hand side, where it came to rest. The aircraft sustained minor dents on the right main landing gear door and on the right flap.

Subsequent engineering work could not replicate the reported brake fault. However, as a precaution, the brake cable rigging was checked, and the brake metering valve and the anti-skid computer were replaced.
