Incident Sequence
Shortly after takeoff, the pilot was unable to retract the landing gear and received failure indications affecting both the lift dump and anti-skid systems. The aircraft proceeded to land successfully at Farnborough. Following discussions with the maintenance organization, the aircraft was subsequently flown to Blackbushe for further technical investigation.
Runway Excursion
Upon landing on Runway 26 at Blackbushe, the aircraft departed the runway surface, struck a series of obstructions, and was destroyed. There was no fire, and the pilot sustained no injuries.
Investigation Findings
Examination of the aircraft revealed that the support bracket for the right main landing gear weight-on-wheels switch had sustained a pre-impact failure. This failure accounted for the indications reported by the pilot during the initial flight.
Recommendations
As a result of the investigation, five recommendations have been made to address the findings.
