Narrative:Because of problems in transferring fuel from the specially installed ferry tanks to the engines, the crew decided to return to Kulusuk, but didn't sight the airfield in deteriorating weather conditions. The aircraft then hit snow when trying to make an emergency landing near a radar site.
a. The crew was properly certified for the flight.
b. According to the crew the normal aircraft systems, except for the FDR and the cockpit right front window electrical deicing system, were functioning normally, which was also determined by the on site investigation.
c. The auxiliary ferry fuel system was not functioning properly. The cause of this has not been conclusively established.
d. The crew did not undertake a satisfactory functional airborne check of the auxiliary ferry fuel system to ensure that it worked prior to the essential appliance of the system for flight, (cause-factor)
e. It is the opinion of this department from the evidence available that a deficiency in the procedures applied for operating the auxiliary ferry fuel system may have been a major factor.
f. The assistance rendered to the flight of YN-BZF was active and generally professional. However, the AFIS operator erroneously stated the distance from the KK NDB of 3 NM to be 10 NM. Furthermore the bearing from the KK NDB was not stated by the AFIS operator at BGKK on request from the crew of YN-BZF.
In the opinion of this department the lack of this information does not seem to have had any important bearing on the possibility of locating the aerodrome.
g. Weather conditions were a major factor in this accident, at the time of the approach into BGKK, as well as at the accident site, (cause-factor)
h. The Search and Rescue operation was anticipated at an early stage and put into effect immediately after the aircraft was considered to have had an accident.
i. The conditions offered on the accident site: low visibility approaching darkness, and consequently the inability to evaluate surface conditions, precluded successful rescue in the first attempt.
