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 18, 2016, about 1230 Alaska daylight time, a tailwheel-equipped Stinson 108 airplane, N343C, sustained substantial damage following a structural failure of the left main landing gear during the landing rollout at Haines Airport, Haines, Alaska. The certificated private pilot, and three passengers were not injured. The airplane was registered to and operated by the pilot, as a visual flight rules (VFR) personal 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. The flight had departed Skagway, Alaska about 1200, destined for Haines.

During an interview with the National Transportation Safety Board (NTSB) investigator-in-charge (IIC) on July 18, 2016, the pilot stated that he was flying three of his family members home to Haines from Skagway. Wind at the Haines Airport was reported to be a left quartering tailwind of less than 4 knots. The pilot performed a normal landing on runway 26 with the intent of exiting the runway via a right turn onto taxiway "B". About 100 feet prior to the taxiway, while at an estimated speed of 20 mph, the airplane turned unexpectedly to the right and made a rapid 180 degree turn. The pilot applied left brake pressure but the right turn continued. About halfway through the turn, the pilot felt two lurching events in succession and then felt the left main landing gear fold up under the aircraft. The left wing and propeller struck the runway surface and the airplane collapsed onto the left side of fuselage. The pilot stated that there were no environmental or performance issues that should have precipitated a ground loop. The airplane sustained substantial damage to the left wing, left lift strut and lower fuselage. 

A postaccident examination by the pilot revealed that the left landing gear leg separated in two places with the first near the axle and the second near the upper shock strut attachment points. The left wheel separated from the assembly and both the wheel assembly and axle were located about 10 feet in front of the propeller. Photographic evidence revealed extensive corrosion on the inner sleeve of the fractured axle. 

A subsequent inspection of runway 26 revealed 2 lines of black tire marks that were consistent with a right turn during braking action. An estimated 25-foot-long ground scar was consistent with bare metal scraping that trailed from about 110 degrees magnetic, prior to the final airplane resting location.

The axle and hub assembly have been retained and a detailed examination is pending. 

The closest weather reporting facility is Haines Airport, Haines, Alaska. At 1154, an aviation routine weather report (METAR) from the Haines Airport was reporting in part: wind from 150 degrees at 3 knots; sky condition, clear; visibility, 10 statute miles; temperature 70 degrees F; dew point 57 degrees F; barometric pressure 29.90inHG.

HAINES, Alaska (KTUU) A non-injury plane crash caused the Haines Airfield to close for about an hour and a half Monday, according to Alaska State Troopers.

Troopers observed the small, apparently damaged plane 12:25 p.m. and contacted the pilot and passengers, according to a dispatch posted online. While no one was hurt, pilot Shane Horton told troopers that the landing gear had buckled during landing. The wing and prop struck the ground.


The FAA, National Transportation Safety Board and state Transportation Department were notified, and the plane was photographed before removal from the runway, troopers wrote. The plane is a Stinson 108-2, according to FAA records.
