§ 33. Commander Courtneyasked the Civil Lord of the Admiralty what methods are employed for prevention of deterioration whilst at sea of helicopters installed in frigates and other of Her Majesty's ships.
§ Mr. C. Ian Orr-EwingManufacturing specifications take account of the special conditions in which these helicopters have to operate. Once in service, they are stowed in snips' hangars when not in use and additional protective measures are employed such as the de-watering oil process, the washing down of the external surfaces with fresh water, and using sprayed lanolin coatings.
§ Commander CourtneyIs my hon. Friend aware of the potentialities of a new type of collapsible aluminium hangar which has been developed in this country and which, I understand, is in use in the Royal Canadian Navy?
§ Mr. Orr-EwingI was not myself aware of this, but if my hon. and gallant Friend sends me details I should be happy to draw it to the attention of our design authority.
