Analysis

The group of 6 airplanes were practicing formation flight for an airshow the following day. The airplanes were to takeoff in three groups of 2-airplane elements. The pilot in the lead airplane in the first group reported that, during taxi to the runway, he had come to a stop at the hold short line. The pilot who was in the second airplane, which was taxing behind the lead airplane, became distracted with the radios before looking up and seeing that the lead airplane had stopped. The pilot applied excessive braking; however, the tailwheel lifted off the ground. To prevent the propeller from ground impact, he released the brakes and the airplane collided with the lead airplane’s empennage. The lead airplane’s rudder and elevator were substantially damaged. The second airplane received minor damage.

Neither pilot reported that there were any mechanical failures or malfunctions with either airplane that would have precluded normal operation.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The second pilot’s diverted attention while taxing which, resulted in his failure to maintain clearance from another airplane holding short of the runway. 

Findings

Personnel issues (A1) Monitoring other aircraft - Pilot of other aircraft
Environmental issues (A1) Aircraft - Contributed to outcome
Personnel issues (A2) Monitoring other aircraft - Pilot
Environmental issues (A2) Aircraft - Contributed to outcome

  2. Maybe the 18,000 hour ATP needed a little more experience?? It could happen to any of us. If you think it can't then "tag you are it"

    1. It was not the 18,000 hour pilots fault, The lower time pilot ran into him after becoming distracted.
