Circumstances:
The Learjet 40 was being operated by two A&P mechanics for the purpose to taxi out for an engine test run on the n°1 engine. During taxi it was necessary to stop the aircraft for motor vehicle traffic. The mechanic advanced the throttles for taxi and to climb a 15 to 20 foot hill. When the mechanic attempted to reduce the throttles only the n° 2 engine could be retarded. The n°1 engine was at a high power setting and could not be reduced. The aircraft left 4 skid marks as the main tires were locked for approximately the length of a little more than a football field. The mechanics could not shut down the n°1 engine. Control of the aircraft was lost with the n°1 engine at a high power setting. The right wing impacted the corner of a hanger. The nose gear broke and an embankment stopped the aircraft. The mechanics were then able to shut down both engines and exited the aircraft with no injuries.
Probable cause:
The NTSB did not proceed to any investigation on this event.
