Accident Details
The flight instructor reported that, during a night landing, the pilot receiving instruction allowed the twin-engine airplane to drift left of the centerline at touchdown. The pilot then overcorrected with right rudder, causing the airplane to veer to the right. The pilot subsequently locked the brakes. The airplane continued to veer right and exited the runway.
Instructor Actions
The flight instructor stated that he did not request control of the flight controls but asked the pilot to release the brakes, which was unsuccessful. After the airplane exited the runway, the instructor had only right rudder and nosewheel steering available. He "fishtailed" the airplane further to the right before the left main landing gear collapsed.
Weather Conditions
The automated weather observation system at the accident airport reported that, around the time of the accident, the wind was from 230° at 9 knots. The pilot landed on runway 21.
Damage and Mechanical Status
The airplane sustained substantial damage to the left wing. The flight instructor reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
