Dear Sir, We have carried out certain tests on sample plugs of the above type. A report of these tests is attached herewith, together with certain engine particulars which you requested. With regard to particulars as to average length of service which we are getting from our existing plugs. We have no figures available on this, as all our engines at present are installed in Service aircraft and routine adjustments are carried out every 10 to 20 hrs. flying. Yours faithfully, For Rolls-Royce Ltd. Attachments. | ||
