Recommendation
A maintenance policy should be instigated for the ruptured duct and all similar ducts.
Action Taken
A study into the need for a preventative maintenance/lifing policy for this and similar ducts has been concluded by the Designer (BAE Systems).
OK, so the study is complete. BAe Systems would not have carried it out without a formal request from the RAF. Was that request issued before or after 2 Sep 06? The Unit Enquiry recommendation was issued in 2005.
