To ask the Secretary of State for the Environment which company is supplying the main door drive units at RAF Mawgan; and whether extensive prototype tests have been carried out to the satisfaction of the Property Services Agency.

Pursuant to the answer given by the Parliamentary Under-Secretary of State, my hon. Friend the Member for Southampton, Itchen (Mr. Chope) on 3 July at column 505, subsequent investigation has shown that the units have been assembled from a variety of components from various sources by CIMOLAI, the steelwork sub-contractor, to designs developed from the earlier prototype tests. NEUERO'S involvement was restricted to giving limited advice on request to CIMOLAI.
