    Well, there's still paragraph 1 and 2 to comply with! Paragraph 3 alone, as reworded, would also place the same restrictions as 1 and 2, without exception.

    What I'm saying is that, as it is currently worded, Paragraph three sounds like an alternate means of compliance.

    Yes, your airplane may get an affected engine installed back at any time. The amended ETOPS manual would render this airplane not ETOPS.
    The EAD states:

    The engines from these events are confirmed to have similar damage in the High Pressure Compressor (HPC), specifically a fracture of the knife edges of the rear hub. The investigation of these events is focused on a configuration change incorporated at serial number P770450.
    Why would you allow an operator to remount an engine "which [has] high pressure compressor aft hub modification embodied from ESN P770450" and is thus "more susceptible to IFSD" for reasons that are still under investigation? Hopefully you require them to either shelve that engine until the investigation is resolved or, if possible, remove the modification.

      Is the A321neo considered part of the "Airbus A320neo family aeroplanes"?

        Are you related to our German friend?

          For the same reason that the EAD is allowing you to keep flying indefinitely an airplane with such an engine (but only one of them, not 2).

            Well, hopefully the mandate is to get these off passenger jets within a 'reasonable timeframe' —and once off, keep them off—until the issue can be resolved.

            Or does it have to take an uncontained failure / headline story to do that?

              Yes, it is. "A320 family" = A318, A319, A320 and A321. "A320neo family" = A319neo, A320neo and A321neo (there is no A318neo).

                  One of their two 321's has been grounded for the time being. The other is not affected by the EAD.

                  Reuters says Airbus has stopped test flights as well as deliveries of the PW1100-powered A320neo variant for the time being. Airlines and lessors have already been consulted, the report said, adding that new deliveries could be delayed by as much as six months.

                  As of February 12, ch-aviation research shows the following airlines have grounded A320/321neo aircraft: Air Astana (one A321neo), Air China (three A320neo), Hawaiian Airlines (one A321neo), HK Express (one A320neo), Indigo (three A320neo), LATAM Airlines (two A320neo), Lufthansa (one A320neo), Sichuan Airlines (three A320neo), Spirit Airlines (one A320neo), Tianjin Airlines (two A320neo), VietJetAir (one A321neo), Volaris (one A320neo), and West Air (China) (one A320neo).

                  Still, this might mean other NEO's in these fleets are operating non-ETOPS routes with one of the affected engines and thus at a heightened risk of in-flight engine shutdown.

                    Sounds like that's thirteen more airlines to add to your no-fly list.

                      They've got 9 on order, most of which are scheduled for delivery before July. My guess is they'll be very motivated to agree with you about the (apparently contradictory) para 3 of the EAD.

                        Hawaiian Airlines has confirmed it will operate a non-stop service between LGB and HNL starting 6/1/2018 using A321neo aircraft powered by PW1000 engines.
