Angus Robertson: To ask the Secretary of State for Defence when his Department received copies of Martin-Baker's Special Information Leaflets, SIL 704 and SIL 704A; and what steps it has taken to incorporate the revised checks into the appropriate maintenance publications. [190344]
Mr Dunne: Special Information Leaflet (SIL) 704 was received on 15 November 2011 and SIL 704A on 18 November 2013. Corresponding Ministry of Defence (MOD) Technical Instructions were issued on 16 November 2011 and 5 December 2013 respectively to ejection seat maintenance units. Both Technical Instructions mandated checks of the ejection seat drogue shackle that were more stringent than those laid down in the SILs. In both cases, amendment action to the appropriate MOD maintenance publications commenced soon after issue of the Technical Instruction.
Angus Robertson: To ask the Secretary of State for Defence if he will place in the Library a list of Martin-Baker's Special Information Leaflets, with contents summary, issued between 1990 and 1996. [190345]
Mr Dunne: Martin-Baker Aircraft issues Special Information Leaflets (SIL) to the Ministry of Defence as a contract deliverable for each aircraft type. The Department does not therefore necessarily receive a copy of every SIL issued by the company. Information on SILs relating solely to aircraft types and equipment that are no longer in-service is not held centrally and could be provided only at disproportionate cost. A list of those SILs that are known to have been received by the Department between 1990 and 1996, with contents summaries, will be placed in the Library of the House.
