HC Deb 23 April 1952 vol 499 cc377-8
13. Mr. Shepherd

asked the Minister of Civil Aviation the findings of his Department on the question of metal fatigue in aircraft; and what action he has taken in order to ensure action on the findings.

Mr. Maclay

The problem of metal fatigue is not new, or confined to aircraft, but higher flying speeds and the longer working life required of aircraft have increased the attention which must be given to it. Tests are made by the Ministry of Supply to assist aircraft designers and the Air Registration Board and the results are notified to them. Any necessary precautionary action is then ordered by the Board.

Mr. Shepherd

As it is stated that existing design would not be compatible with the light alloys being used, is the Minister taking any action to see that alterations in existing design are made to account for this?

Mr. Maclay

I ask not to be requested to reply to that question today. I should require further examination.

Air Commodore Harvey

Is my hon. Friend aware that the Royal Aircraft Establishment at Farnborough and airframe manufacturers have this matter well in hand and are fully satisfied that all immediate safeguards have been taken?

Mr. Maclay

Yes, Sir. That is correct.
