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 July 19, 2016, about 1030 Alaska daylight time, a tailwheel-equipped Cessna 185E airplane, N85CF, had the left main wheel and axle separate from the landing gear strut during the landing rollout at an unimproved landing strip 20 nm west-northwest of Illiamna, Alaska. The commercial rated pilot and three passengers were not injured. The airplane sustained substantial damage. The airplane was registered to, and operated by, the pilot as a visual flight rules (VFR) other work-use flight under the provisions of 14 Code of Federal Regulations (CFR) Part 91. Visual meteorological conditions prevailed at the time of the accident, and no flight plan was filed.
During an interview with the National Transportation Safety Board (NTSB) investigator-in-charge (IIC) on July 20, 2016, the pilot stated that during the landing roll out, the left wheel separated from the axle and rolled away from the airplane. The left main landing gear leg dug into the gravel landing surface, which resulted in a sudden left turn. The left wing, elevator, lower engine cowling, and propeller struck the ground. The airplane sustained substantial damage to the left wing.
A postaccident examination by the pilot revealed that the 4 wheel bolts at the axle connection were broken. The attach bolts and axle have been retained and a detailed examination is pending.
