Unfallbericht:
During a high speed taxi for a maintenance test, the aircraft became airborne, the pilot experienced a loss of control when the aircraft re-contacted the runway.
The pilot reported a thrust reverser deployment problem on a previous landing roll-out. Maintenance personnel requested a high speed taxi to simulate the discrepancy. During taxi procedures the thrust reverser system operated correctly. During the high speed taxi check on Runway 30 the thrust reversers were deployed which caused the aircraft nose to pitch up, followed by the aircraft becoming airborne. Thrust reversers went to auto stow when the landing gear left the ground. This action caused the aircraft to suddenly pitch nose down, upon contact with the runway the nose landing gear was sheared off. The right main landing gear also sheared off as control of aircraft was lost. The aircraft skidded off the runway and came to a halt. Substantial damage to the aircraft and minor injuries were incurred to the pilot and one maintenance technician.

Probable Cause:

No formal investigation was conducted as no intent for flight existed and the occurrence thus did not meet the ICAO Annex 13 definition for an Accident.
