Dear all,
It^s been a while since I was involved in A330(/B777) ETOPS on the maintenance side.
Lately, I have been trying to catch up with the implications of the ETOPS revision from "two engines only" to the "extended ops" concept, see
http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgAdvisoryCircular.nsf/0/2e0f31985abd83ef8625746b0057fd06/$FILE/AC%20120-42B.pdf
, in particular for the effects on the MRO side (Job Cards, Engineering procedures, defect rectification etc. - NOT route and fuel planning!).
Using google for relevant documentation usually ended up in old-style "E-TWIN-OPS" stuff.
I have checked a few of our A340 customers´ procedures and manuals - no trace of "ETOPS". Might be that they don^t operate the routes as quoted in appendix 2, items 2 and 3...?
- Strictly speaking on the 3 and 4 engined airplanes: Any maintenance implications? Any analogon to the "Dual maintenance" concept on A330s?
- Has anyone seen relevant documentation from the EASA? I could only find the FAA AC above.
- Has anyone seen a "CMP" for the A340?
- Any changes on your Part 145 end to handle an A340 when compared to five years ago...?
Very confused regards, :confused::confused:
