This is preliminary information, subject to change, and may contain errors. Any errors in this report will be corrected when the final report has been completed. NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

On November 12, 2016, about 1230 Alaska standard time, a tailwheel-equipped Cessna 185 airplane, N4918Q, sustained substantial damage during the landing roll at the Ninilchik Airport, Ninilchik, Alaska. The certificated airline transport pilot and the pilot-rated passenger sustained no injuries. The airplane was registered to, and operated by, the pilot as a visual flight rules (VFR) flight under the provisions of 14 Code of Federal Regulations (CFR) Part 91. Visual meteorological conditions prevailed at the time of the accident, and a VFR flight plan had been filed. The flight originated from the Soldotna Airport, Soldotna, Alaska, about 1200. 

During a telephone interview with the National Transportation Safety Board (NTSB) investigator-in-charge on November 13, the flying pilot, who was seated in the right seat at the time of the accident, stated that after an uneventful touchdown on the slightly wet and gravel surface of runway 10, the right side brake system did not function as designed, which resulted in an asymmetrical braking condition. As the airplane continued the landing roll, the airplane ground looped to the left and the right wing and right horizontal stabilizer impacted the runway surface. The airplane came to rest on the runway without further incident. 

The accident pilot stated that the previous landing was accomplished by the pilot-rated passenger and she reported no issues with the brake system during that landing sequence. The pilot further stated at the time of the accident, the wind condition originated from the north, about 10 to 15 knots.

The airplane sustained substantial damage to the right wing and the right horizontal stabilizer. 

The closest weather reporting facility was the Homer Airport, Homer, Alaska. At 1153, an Aviation Routine Weather Report (METAR) was reporting in part: wind from 080 degrees at 17 knots, gusting 24 knots; visibility 6 statute miles; sky condition broken 3,600 feet; temperature 45 degrees F; dew point 37 degrees F; altimeter 29.11 inHg.
