Confusion regarding 787 engine issues

Yesterday I reported that several 787s needed to ave their thrust reversers changed out as there is an issue with several of them.  Today another source told me that there aren't any issues with the thrust reversers but there are one off issues with the GE engines and that the engines on a JAL 787-9 airframe are being changed out which necessitated the removal of the thrust reversers for the change out.

Just this evening another source said that ZB376 (LN 481, G-ZBKO) for British Airways is being rolled out tonight sans its Rolls Royce Trent-1000 motors.

There clearly seems to be some sort of issue but the information I have says that there isn't any systemic issue with the 787 thrust reversers.  It does appear that test flights, for the most part, are on hold for the time being.  What is still unknown is the nature of these issues and the affect on the test flight and delivery schedule.

Lastly in news unrelated to the engine issue; Boeing South Carolina will shut down for about 11 days (between August 22 and September 2nd) so that suppliers can retool for the 787-10 production that will start later this year.  It will also give Boeing to catch up on late work and allow some workers to take vacation.  I'm not sure if the same is happening in Everett.

Hi Uresh


I was at CHS last week just before the latest Avianca B788 was delivered and noted that it was carrying the registration N791AV and not N787AV.

Hi Uresh,

I was down by Boeing South Carolina the other week and got some pictures of the flight line. If you would like to use them on the blog I'd be more than happy to email them to you. I can be reached at mohrmd1994@gmail.com.

Also, have you heard anything about 787 production. It seems that with the 787-10 being solely produced in Charleston that Boeing may move all 787 production there. If I remember correctly the facility there can handle two 787's in parallel, but some work may need to be done to reduce the number of stations. Also the painting facility there looks like it would be able to accommodate more than 7 airplanes a month.

RR engines - ANA - It was reported this week they may be replacing ALL their engines, even though deliveries have been throughout the program. It was my understanding the problem has been isolated to compressor blades.
Please let us know the actual part and whether it was a bad run for that part, thus affecting certain engines, or whether it is a design problem, therefore affecting all the Trents.

Boeing must be Concerned about 787 repo
