| Action description |
On the 25 May 2011, Rolls-Royce advised the ATSB that a major corrective action, which arose from an internal major quality investigation, was to remove the existing retrospective concession procedures from their quality system, and replace them with a new Global Process titled Management of Undeclared Non-Conformance in Delivered Product. The global process was developed to ensure an improved and more consistent approach across the company when it is identified that parts containing undeclared and non-conforming features have been released to the customer for entry into service. The global process included a technical review by a statistic expert. The global process was incorporated into the engine manufacturer’s quality management system on 4 July 2011. |
| ATSB response |
The ATSB is satisfied that the action taken by Rolls-Royce adequately addresses this safety issue and therefore makes no recommendation. |
| Action status | Closed |
