Registration: N677M
Aircraft: Reed Mike SMITHS SUPER CUB
Aircraft Damage:Substantial 
Defining Event: Loss of control on ground
Injuries: 1 None
Flight Conducted Under: Part 91: General Aviation - Personal


The pilot reported that, during the landing roll on a dirt airstrip, the airplane skidded on a thin layer of frost on the dirt. He applied the brakes, and as the airplane transitioned to dry gravel, it nosed over. He added that he believed that the braking pressure he applied was excessive for the gravel portion of the airstrip. The airplane sustained substantial damage to the right-wing lift strut and rudder. The pilot reported that there were no preaccident mechanical failures or malfunctions with the 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 pilot's excessive use of brakes during the landing roll, which resulted in a nose-over.


Surface speed/braking - Capability exceeded (Cause)
Brake - Incorrect use/operation (Cause)

Personnel issues
Aircraft control - Pilot (Cause)

Environmental issues

  1. Love the cubs! She’ll be ok and back flying soon I hope!

  2. "had in fact locked up the brakes" with full flaps is inexcusable after 368 total hours this make and mode.
