Although 51-16474 was intended to be delivered to the Alaska Air Command at Ladd AFB, it was actually delivered to Elmendorf, where it spent its whole USAF life, initially with the 5039th Air Transport Squadron from 11-Jan-1952 until 16-Apr-1952. An allocation to the 5039th Air Depot Wing, for a month followed before going back to the Air Transport Wing from 17-May-1952. This allocation again lasted a month when it suffered an accident at Fire Island Airstrip, near Anchorage, Alaska on the 13-Jun-1952 receiving minor / medium damage in a landing accident. It was then returned to the Air Depot Wing until 06-Mar-1953 and again back to the Air Transport Group for a month until 13-Mar-1953.
In March 1953 the Air Depot was re-designated as 5039th Air Base Wing so this is where the aircraft was allocated from 13-Mar-1953 until a re-allocation to the 5th Liaison Squadron on the 23-Apr-1953; it suffered a category 2 accident at Cape Newenham, Alaska on 30-Apr-1953 with minor / major damage during a takeoff. The pilot was Jean E. Crabtree. It appears to have had a collision with Ser No 51-16475. Following this incident it was passed to the 5025th Maintenance wing for a lengthy stay until 21-Jul-1954, however it is recorded as having a further ground collision accident 23 mi. East of Nome, Alaska on 02-Jul-1953 and being attached to the 5th Liaison Squadron. The pilot on this occasion is reported as Colan R Lanier.
It was then back to the 5039th Air Base Wing (Air Transport Squadron) for a relatively long deployment until 10-Oct-1956, during which it suffered a category 3 accident (major/serious damage) This was at Fire Island, Alaska on 03-Jan-1955. The pilot was Woodrow H. Stoker and involved a landing accident. A further accident occurred on 21-Dec-1955 at Campbell Airstrip, Alaska. This time the pilot was Thomas F. Kenney and again a landing accident was involved. These accidents were prior to going to 5039th Maintenance Squadron between 10 & 20–Oct-1956. A return to the 5039th Air Base Group until Jun 1957 when it was re-designated the 5040th Air Base Wing where it remained until being passed to the Civil Air Patrol on 20-Apr-1960.
