The main submission to Lord Philip (see above) revealed that the FADEC Safety Critical software did not have a Certificate of Design, and was therefore not cleared to be fitted to Chinook HC2. It further revealed that John Spellar MP had been wrong when claiming the software was not Safety Critical, providing the original policy document governing this definition to Lord Philip. MoD subsequently claimed it did not have its own copy, calling into question how it could advise Spellar one way or the other.
