[Official Report, 27 January 2009, Vol. 487, c. 310-12W.]

An error has been identified in the written answer given to the hon. Member for Woodspring (Dr. Fox) on 27 January 2009. The entry in the table for the Sentry aircraft was incorrect.


18 Nov 2009 : Column 2MC

The correct answer should have been:

Mr. Quentin Davies: The required level of spares for RAF aircraft is included in contractual agreements with industry, or is set by the Front Line Command. The achieved level of available spares is measured as part of these agreements.

The following information for the required and achieved level of spares is provided as at 30 November 2008 unless otherwise stated. Although not used as a performance indicator as part of a contract with industry, the off the shelf satisfaction rate (OTSSR) is also measured for some aircraft types, and is therefore included in the table. The OTSSR is defined as the percentage of demands for spares satisfied direct from MOD stock.

Departmental Budgets

Dr. Fox: To ask the Secretary of State for Defence what his Department's science innovation and technology budget is for 2010-11. [284525]

[Official Report, 1 September 2009, Vol. 496, c. 1798W.]

Letter of correction from Mr. Quentin Davies:

An error has been identified in the written answer given to the hon. Member for Woodspring (Dr. Fox) on 1 September 2009.

The correct answer should have been:

Mr. Quentin Davies: The current planning assumption is that the SIT budget will have available approximately £439 million in 2010-11. This compares with £544 million in 2010-11 in a previous planning cycle when calculated on the same basis. Departmental expenditure limits have not yet been set for the years beyond 2010-11.
