PROBABLE CAUSE: "The Board was of the opinion that two successive errors of judgment were committed by the pilot. These were as follows: (1) He initiated a landing procedure at an aerodrome with which he was not acquainted, in weather conditions which were lower than the minimum prescribed for landings on that aerodrome; (2) On arrival over the aerodrome, he flew at too low an altitude over a terrain which he must have known to include a hill which constituted a hazard for his aircraft, which hill he was not able to see, on account of the poor visibility and low cloud. The Board further considered that the following factors contributed towards the accident to a considerable extent: a) air traffic control did not advise the pilot to delay his landing until the weather conditions had improved, or otherwise to divert to another aerodrome; b) air traffic control designated a runway for the landing which necessitated the aircraft venturing low over dangerous terrain as indicated in 2) above."
