Maintenance of jet liners:

ENGINE CHANGE IN AN HOUR

The ease and simplicity of routine maintenance of the gas-turbine engine has been underlined by details of the behaviour of the pure jor engines of the de Havilland Comet.

The makers have described the operation of the four Ghost engines in their first 300 hours flying in the Comet. This number of hours was flown in about 10 months (an average of, nearly one flying hour a day) much of it in winter, and included record-breaking flights around Europe as well as tropicalisation and high altitude tests in Africa.

To keep up this high average The jet has another contribu of flying hours, de Havillands tion to make towards reducing have replaced the jet engines costs.
