re 15,000 Miles Test - 5-B-IV.

Sg{Arthur F. Sidgreaves - MD}24/E14.5.35

Referring to Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}9/KW.13.5.35 you say that from Hancock's daily report I will see that he has had a pivot failure.

The report, however, indicates to me something much more serious than that, i.e. that a stub axle broke off just behind the rear ball race.

This of course is an appalling thing to happen as it means the wheel coming off and probably a fatal accident to the occupants of the car.

It is certainly important that the parts are returned to Derby for examination and I shall be very anxious to hear the result.

I note that the parts in question have done a previous 15,000 miles test but, as the accident occurred at just under 8,000 miles on 5-B-IV, the total running would be much less than the 30,000 referred to in your memo.
