Accident: 7 Mile Lake, AK. 23-Jul-2006. The first pilot was conducting a local area Title 14 CFR Part 91 proficiency/instructional flight in a float-equipped airplane with the second pilot. Both pilots were certificated flight instructors. After landing at a lake, the second pilot practiced making step turns. The first pilot, seated in the right seat, then took the flight controls to demonstrate continuous water taxiing/turning while on-step. He said he taxied around the perimeter of the lake and began a right turn, still on-step, but the airplane did not respond. Application of right rudder did not prevent the airplane from colliding with the lake shore and trees. The airplane received damage to the left wing and fuselage. The first pilot indicated that the wind was about 6 knots from the north-northeast, but he thought the airplane encountered a wind shear at the narrowest portion of the lake where the accident occurred.

This lasted until 08-May-1957, with a brief return to Showa, Japan occurring between Nov-1956 and Feb-1957. The 58th FB Wing was de activated with a change in defence strategy towards missile Defence and the aircraft moved to the 6314th Air Base Group, the host Unit at Osan. It remained with the wing until 1964 with a few deployments to Kunsan, Seoul, Taegu and Kimpo including the renaming of the wing as 6314th Support Wing in 1961. There is a note of it going to the Logistics Command Fairchild Aircraft Service Facility in early 1964 but returning to Taegu with the 6314th Support Wing from 26-Mar-1964 and then to Osan with the AMAMA (currently unknown acronym) from 16-May-1964.
