I would like to post a twofold 2019 wish :
- let A320neo engines be in 2019 so reliable, so problem-free, that we forget that they ever were a source of concern !
- let production run smoothly at both manufacturers' and meet or exceed targets !

Based on the Article written by Flight Global. P&W has quite a bit of work to do to get the GTF operating smoothly. Although, much of the complaints only came from one Airline, which really is not a good assessment of GTF Engines operating worldwide. it would be awesome to hear more about both GTF & LEAP performance on a regular basis...one can only wish....

It is interesting how fluid and dynamic this industry is. The last article i commented on was not as positive as this one. Would be nice if they could do a follow up in 6 months and see how lufthansa and P&W are progressing.

Those requirements were brought by lightsaber in the discussion on airliners.net about T XWB performance. FAA ETOPS requirements per 14 CFR 21.4
In-flight shutdown (IFSD) means, for ETOPS only, when an engine ceases to function (when the airplane is airborne) and is shutdown, whether self induced, flightcrew initiated or caused by an external influence. The FAA considers IFSD for all causes: for example, flameout, internal failure, flightcrew initiated shutdown, foreign object ingestion, icing, inability to obtain or control desired thrust or power, and cycling of the start control, however briefly, even if the engine operates normally for the remainder of the flight. This definition excludes the airborne cessation of the functioning of an engine when immediately followed by an automatic engine relight and when an engine does not achieve desired thrust or power but is not shutdown.
(i) A rate of 0.05 per 1,000 world-fleet engine-hours for an airplane-engine combination approved for up to and including 120-minute ETOPS. When all ETOPS operators have complied with the corrective actions required in the configuration, maintenance and procedures (CMP) document as a condition for ETOPS approval, the rate to be maintained is at or below 0.02 per 1,000 world-fleet engine-hours.
(ii) A rate of 0.02 per 1,000 world-fleet engine-hours for an airplane-engine combination approved for up to and including 180-minute ETOPS, including airplane-engine combinations approved for 207-minute ETOPS in the North Pacific operating area under appendix P, section I, paragraph (h), of part 121 of this chapter.
(iii) A rate of 0.01 per 1,000 world-fleet engine-hours for an airplane-engine combination approved for ETOPS beyond 180 minutes, excluding airplane-engine combinations approved for 207-minute ETOPS in the North Pacific operating area under appendix P, section I, paragraph (h), of part 121 of this chapter.www.law.cornell.edu/cfr/text/14/21.4So we have the 0.05 max engine shutdowns per 1000 flight hours for ETOPS 120. The GTF is according to the flightglobal article at 0.02 engine shutdowns per 1000 flight hours at Indigo. Well below the limit for ETOPS 120. On the limit for ETOPS 180. And we are talking about the operator with the worst experience, as far as I followed the discussion. |

That was quite interesting! I didn't realise that engine updates were done through a physical connection to the actual engine rather than from the flight deck. As for the bricked engine, maybe they just need to rip out the ROM and install a new one.  |
