Date & Time: 07/16/2018, 0925 AKD
Registration: N1822M
Aircraft: Curtiss Wright C46
Aircraft Damage: Substantial
Defining Event: Unknown or undetermined
Injuries: 2 Minor

Analysis 

The pilot reported that, following a precautionary shutdown of the No. 2 engine, he diverted to an alternate airport that was closer than the original destination. During the landing in tailwind conditions, the airplane touched down "a little fast." The pilot added that, as the brakes faded from continuous use, the airplane was unable to stop, and it overran the end of the runway, which resulted in substantial damage to the fuselage.

The pilot reported that there were no mechanical malfunctions or failures 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 failure to attain the proper touchdown speed and his decision to land with a tailwind without ensuring that there was adequate runway length for the touchdown.

Findings

Aircraft
Airspeed - Not attained/maintained (Cause)

Personnel issues
Aircraft control - Pilot (Cause)
Decision making/judgment - Pilot (Cause)

Environmental issues
Tailwind - Effect on operation

Great job getting this old warbird back on the ground. Viewing photos, they were very fortunate to have only minor injuries. I wonder if they were loaded? One had a glider rating, but this isn’t much of a glider. One engine performance must be good with just one r2800.
