Narrative:

The following narrative describes a ground incident only. I was accompanied in the aircraft by mechanics occupying the right seat and the jump seat. The purpose was to attempt, during a high speed taxi, to duplicate a reported thrust reverser deployment problem. All checklists were read by the mechanic in the right seat and the actions were confirmed by me. During the high speed taxi and subsequent thrust reverser deployment, the aircraft pitched up and became airborne. The aircraft veered off the runway and settled onto the parallel sod infield. The right main gear and nose gear collapsed. The aircraft sustained damage that, at this time, appears repairable. The injuries to this writer and the mechanics are minor. Factors to consider: as to whether the ground spoilers were armed or the flight spoilers were deployed after closing the throttles, I simply do not remember. These actions are normally ingrained and therefore routine, but I have no memory of either. Not having a qualified pilot in the right seat was a definite factor. The overlooking of any checklist items would have been brought to my attention by another pilot. The aircraft has a very real problem (nose pitch up) during thrust reverser deployment. I've had several unsolicited phone calls confirming this. This characteristic should be stressed during initial and recurrent training. Fatigue and stress were definite, and maybe the overriding factors. I had been stressed in dealing with personnel problems within my organization. I knew I was tired but, as many mgrs do, decided the job must get done.

Title: A CL601 DURING A HIGH SPD TAXI FOR MAINT TROUBLESHOOTING AT LGB BECAME AIRBORNE AND SUFFERED DAMAGE AFTER EXITING THE RWY.

Narrative: THE FOLLOWING NARRATIVE DESCRIBES A GND INCIDENT ONLY. I WAS ACCOMPANIED IN THE ACFT BY MECHS OCCUPYING THE R SEAT AND THE JUMP SEAT. THE PURPOSE WAS TO ATTEMPT, DURING A HIGH SPD TAXI, TO DUPLICATE A RPTED THRUST REVERSER DEPLOYMENT PROB. ALL CHKLISTS WERE READ BY THE MECH IN THE R SEAT AND THE ACTIONS WERE CONFIRMED BY ME. DURING THE HIGH SPD TAXI AND SUBSEQUENT THRUST REVERSER DEPLOYMENT, THE ACFT PITCHED UP AND BECAME AIRBORNE. THE ACFT VEERED OFF THE RWY AND SETTLED ONTO THE PARALLEL SOD INFIELD. THE R MAIN GEAR AND NOSE GEAR COLLAPSED. THE ACFT SUSTAINED DAMAGE THAT, AT THIS TIME, APPEARS REPAIRABLE. THE INJURIES TO THIS WRITER AND THE MECHS ARE MINOR. FACTORS TO CONSIDER: AS TO WHETHER THE GND SPOILERS WERE ARMED OR THE FLT SPOILERS WERE DEPLOYED AFTER CLOSING THE THROTTLES, I SIMPLY DO NOT REMEMBER. THESE ACTIONS ARE NORMALLY INGRAINED AND THEREFORE ROUTINE, BUT I HAVE NO MEMORY OF EITHER. NOT HAVING A QUALIFIED PLT IN THE R SEAT WAS A DEFINITE FACTOR. THE OVERLOOKING OF ANY CHKLIST ITEMS WOULD HAVE BEEN BROUGHT TO MY ATTN BY ANOTHER PLT. THE ACFT HAS A VERY REAL PROB (NOSE PITCH UP) DURING THRUST REVERSER DEPLOYMENT. I'VE HAD SEVERAL UNSOLICITED PHONE CALLS CONFIRMING THIS. THIS CHARACTERISTIC SHOULD BE STRESSED DURING INITIAL AND RECURRENT TRAINING. FATIGUE AND STRESS WERE DEFINITE, AND MAYBE THE OVERRIDING FACTORS. I HAD BEEN STRESSED IN DEALING WITH PERSONNEL PROBS WITHIN MY ORGANIZATION. I KNEW I WAS TIRED BUT, AS MANY MGRS DO, DECIDED THE JOB MUST GET DONE.
