A related factor was directional control of the aircraft was not possible after the wheel failure. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Airframe/component/system failure/malfunction, takeoff - roll/run - directional control - not possible, pilot in command (contributing factor) - landing gear,wheel - failure (cause) - On ground/water encounter with terrain/water, takeoff - aborted - terrain condition - ground ## Analysis The pilot reported that during the takeoff roll the right main landing gear tire and tube came off. The pilot stated that he aborted the takeoff, however, due to the loss of the tire, the aircraft was difficult to control. The aircraft stopped abruptly when the right wheel assembly dug into the dirt at the side of the runway. The propeller and right side wing contacted the surface. After the accident and during an inspection of the wheel, it was reported that the right main wheel outboard bead failed resulting in the separation from the wheel assembly. ## Factual narrative On April 18, 2006, at 1157 Pacific daylight time, a Cessna 170B, N2886C, registered to and operated by the pilot as a 14 CFR Part 91 personal flight, experienced a main landing gear tire failure while performing touch-and-go landings at Sanderson Field, Shelton, Washington. Visual meteorological conditions prevailed at the time and no flight plan was filed. The aircraft was substantially damaged and the private pilot, the sole occupant, was not injured. The flight originated from Tacoma, Washington, about one hour and 15 minutes prior to the accident. During a telephone interview, the pilot reported that during the takeoff roll on runway 05, the right main landing gear tire and tube came off. The pilot stated that he aborted the take-off, however, due to the loss of the tire, the aircraft was difficult to control. The aircraft stopped abruptly when the right wheel assembly dug into the dirt at the side of the runway. The propeller and right side wing contacted the surface. After the accident and during an inspection of the wheel, it was reported that the right main wheel, outboard bead separated from the wheel assembly. ## Aircraft - Registration: [N2886C](https://openairdocs.org/aircraft/N2886C), registered now, S/N 26429, built 1954 (OpenAirDocs) - Reported make and model: Cessna 170B - Registry model: [Cessna 170B](https://openairdocs.org/model/cessna-170b) (registry code 2072306) (OpenAirDocs) - Registry engine: [Continental C145 series](https://openairdocs.org/engine/continental-c145-series) (registry code 17012, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 26429 - Engines: Lycoming O-360-A2F reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Robert E.
