| - 2 - EP {G. Eric Platford - Chief Quality Engineer} 1/H28.4.22. present the most abstruse difficulties, and it would be interesting to know to what extent with other engines such things as excessive end-thrust in the crankshaft may contribute towards productions of undesirable vibrations" I take it that you will take an opportunity of carrying out experimentally such action as is suggested by PN. {Mr Northey} above. I propose to test 81-TW at the next possible opportunity, in fact the matter may be of sufficient importance after discussing it with PN. {Mr Northey} and Cricklewood to suggest specially putting end play in the crankshaft of this engine, to see whether the vibrations referred to can be reproduced.
