Accident: Kalispell, 23-Jul-2007. While in cruise flight over a wilderness area, the engine sputtered and then lost power. The pilots attempted to restart the engine, and then began to look for a place to land. The pilot landed the airplane on a gravel/sand bar area near a river. The airplane sustained structural damage to the firewall, a wing strut, and leading edge damage to the horizontal stabilizer. The pilots reported that the oil pressure and cylinder head temperature gages were in the green prior to the event, and there was no indication that there was anything wrong. An inspection of the engine revealed that the master rod end had broken. No metal pieces were observed in either the oil filter or oil sump. Further inspection of the engine revealed that the supercharger impeller shaft bearings (blower bushing) had failed. The supercharger impeller bearings are an area that requires lubrication, and if they fail, raw oil can be pumped into the induction system, which could cause various engine problems, including detonation. NTSB Report LAX07LA238.

Note: Accident: Arctic Village AK. 04-Sep-2015 00:40utc. The pilot reported that while departing in a tailwheel-equipped airplane, from a rough and uneven tundra-covered off-airport site, it failed to gain sufficient airspeed, and he aborted the takeoff. The airplane's main wheels sunk into the soft tundra-covered terrain, and the airplane subsequently nosed over, sustaining substantial damage to the wings. The pilot stated that there were no pre-accident mechanical anomalies with the airplane that would have precluded normal operation.
51-16499 was made available on 16-May-1952, and accepted on 29-May-1952 by the 6600th Air Depot AMO (Air Material Overseas Unit), at Downsview, ON., after which it was assigned to the Tactical Air Command. It was delivered to Langley AFB, VA., and joined the 2nd Liaison Flight on 11-Jun-1952 and then 2nd Liaison Sqd on 22-Jul-1952. It moved to Shaw AFB, SC., as a deployment with the 2nd Liaison Squadron on 14-Apr-1954 before returning to Langley on 08-Jun-1954. Remaining at Langley it transferred to the 405th Fighter Bomber Wing on 20-Jun-1954 and then the 4405th Operations Squadron from 23-Aug-1954 until 14-Feb-1955.
It now passed back to Downsview, Toronto, ON., for maintenance until 13-Apr-1955 after which it returned to the 4405th Operation Squadron at Langley. It then went back to Shaw AFB this time to join the 363rd Reconnaissance Combat Training (RCT) Wing between 17-Apr-1956 & 16-Jul-1956 and then to Olmstead AFB, PA., to the Air Material Command, Middletown Air Material Area (MID MIDAR) until 17-Aug-1956. A couple of moves back and forth between Shaw and Olmstead continued until 23-Aug-1957 with the allocations to Olmstead only lasting a couple of days each. The reason for this is unknown.
A change of location and unit occurred on 23-Aug-1957 with a move to Seymour Johnson AFB, North Carolina with an attachment to the 83rd Day Fighter (FDA) Wing. This lasted until 01-Nov-1957 followed by a move to Pope AFB, NC., and the 464th Troop Carrier, Medium (TCM) Wing until 19-Feb-1958. Then it returned to Seymour Johnson but to the re designated 4th Tactical Fighter Wing where it remained for over two years until 29-Aug-1960.
It then departed from the TAC to be assigned to Headquarters Command at Bolling AFB, Washington DC. It was assigned to the 1100th Air Base Wing for just over twelve months until 13-Sep-1961 after which it went to the West Coast Maintenance Area at Lockheed Air Service Inc, Ontario, Burbank, California for a short period until 23-Oct-1961. Another new location beckoned, this time Fairchild AFB, Spokane, Washington. This was a new assignment as well to the Strategic Air Command and the aircraft joined the 92nd Heavy Bombardment (BH) Wing until 20-Feb-1962. From here the aircraft moved to Malmstrom AFB, Montana and the base operating unit, the 341st Strategic Support (SSP) Wing until 26-May-1962. A return to Fairchild where the 92nd had now been re designated as the 92nd Strategic Aerospace (STA) Wing as the SAC moved into missile technology. It stayed until 31-Jul-1962 when it returned to Malmstrom where similarly the 341st had been re designated as the 341st Strategic Missile Wing. A third visit to Fairchild with the 92nd Strategic Aerospace wing occurred between 24-Aug-1962 and 29-Jan-1963 prior to the aircraft moving to the Logistics Command facility at Hagerstown, MD operated by the Fairchild Aircraft Company where it apparently remained in storage until 22-Mar-1964,
It then returned to active service with the 96th Strategic Aerospace Wing at Dyess AFB. Its further history is to be researched.
