by supplementary inspections through RTIs. The Fuel System has been reviewed as part of an
Independent Fuel System Safety Review by QinetiQ. Its Zonal Hazard Analysis has been used to
identify couplings whose seals could be replaced as a precaution and this will be completed under
the actions detailed at Serials 5 and 6. A study undertaken by DE&S DG Safety and Engineering,
involving widespread consultation, both civilian and military, has been unable to find any other
organisation that sets a life for fuel seals. The study determined that there was no requirement to
set a life for fuel seals, but recommended a number of other means to reduce seal failures.
Medium-Term Action Continuing.
The Nimrod Team has developed a 3 strand process to complete this recommendation:
a. An audit of all those systems assessed as having a potential impact on safety or airworthiness
has been completed.
b. The Nimrod Support Policy Statement is being reviewed.
c. The NIMROD TEAM is establishing a robust ‘continuing airworthiness’ regime to ensure
that mechanisms are in place to maintain the effectiveness of maintenance policy until
OSD.
Appendix A to Chapter 15
The results of the Maintenance Policy Review have now been incorporated into the Aircraft
Maintenance Schedule and a final report has been accepted by the Nimrod Team. Once the
Aircraft Operating Authority agrees this report the recommendation will be closed.
