HC Deb 03 March 1948 vol 448 c357
1. Mr. John Lewis

asked the Parliamentary Secretary to the Ministry of Civil Aviation what is the average number of engine hours for a Bristol Hercules engine as fitted to the Viking aircraft before requiring an overhaul.

The Parliamentary Secretary to the Ministry of Civil Aviation (Mr. Lindgren)

In the case of Vikings operated by British European Airways Corporation, 425 hours.

Mr. Lewis

Could my hon. Friend say why engines fitted to Dakota aircraft are able to run for a very much longer period before requiring an overhaul?

Mr. Lindgren

That is a totally different type of engine. The period between overhauls varies with the type of engine.
