Select Committee on Science and Technology Written Evidence

Memorandum by NYCO

  The attention of our company has been recently drawn onto an incorrect statement in the 2000 report of the House of Lords Select Committee on Science and Technology Air Travel and Health.

  The paragraphs 4.35 to 4.41 refer to potential poisoning by components included into the jet engine oil, of which tri-cresyl-phosphate (TCP). This field of jet engine oil formulation is very well known to NYCO SA as a corporation, because we have been designing, manufacturing and marketing such products since 1959.

  Paragraph 4.36 states that "Mr Fogarty of Exxon-Mobil commented that no other additive had been found to match TCP's anti-wear and load-carrying performance". This is not accurate as NYCO SA has been marketing since 1985 a jet engine oil, "Turbonycoil 600", that does not include any TCP in its formulation, albeit containing an additive of the same family. In spite of the absence of TCP, Turbonycoil 600 meets all the technical requirements of the engine manufacturers and military authorities in charge of the approval of such products.

  In particular, it is duly approved to the MIL-PRF-23699 specification, which is the ruling specification for all today's commercial engine oils. Turbonycoil 600 is also approved for over 40 different commercial and military engines manufactured by the Rolls-Royce, General Electric, Pratt & Whitney and Snecma, including the very popular commercial engines CFM56, V2500 and RB211.[81]

  The considerable flight experience accumulated since 1985 on gas turbine engines is a clear evidence that the use of TCP in jet engine oils can be avoided, without compromising at all the quality and performance of the oil in the engine. Turbonycoil 600 is in particular the oil currently used by the Royal Air Force and Royal Navy under the Ministry of Defence designation "OX-27".
