83. Dr. Bennett
asked the Minister of Civil Aviation whether he has ascertained the causes of the two air-liner mishaps in which propellors became detached, over North Africa last month and over France last November, respectively; and if he is satisfied that such mishaps are adequately guarded against for the future.213W
Investigation into the mishap over North Africa last month is not completed, but the primary cause of the failure has been established and preventive action taken. The mishap over France to which I presume my hon. Friend refers occurred last August. Its cause has been ascertained and the Air Registration Board, which advises my hon. Friend in these matters, has made arrangements designed to guard against a recurrence. It is clear that the two mishaps occurred from different causes.
