Oral question asked in the House of Lords, by Earl Attlee (Conservative). It was answered on Thursday, 18 October 2007.

Aviation: Air Quality

Question: My Lords, in respect of this problem, is the Minister as confident about obsolete aircraft designed in the 1960s and 1970s such as the VC10 and Tristar aircraft operated with difficulty by the RAF?

Answer: My Lords, I am grateful to the noble Earl for drawing those particular aircraft to the attention of the House. Most of the problems that appear to have arisen are with commercial aircraft, principally the BAe 146 and the Boeing 757. The Civil Aviation Authority has introduced mandatory action for the BAe 146, and similarly action has been taken with regard to the Boeing 757. There it was discovered that the primary cause was related to engine oil servicing procedures. Those procedures are being revised, and beneficial results are already being shown.
