As the attachment, I send the time of safety buyoff and simulation buy off. Monday of CW17 is 26th APR. Since the W-release data of rear door will be provided on Mid-April, FD area can not do the safety buy off with the other area at the same time. if the time is ok for you, you can tell and then we can discuss which day we can start, although we have a lot area need to check, but some area is similar, for example FA41(V206/214) is similar to the FA45(V254/214), and also FA42 is a mirror of FA41. Wish you have a nice day
