pjvr99 Posted September 9, 2018 Share Posted September 9, 2018 Thank you. based on this and your previous mentioning the shift to another engine, it sounds like you have a rollback, a problem with the synchrophaser. Check out synchrophaser, sych rack, and also run synch box tester. sometimes the problem can be a false signal generated by a seemingly good valve housing. also check all 4 prop pulse generators.

Muneer is saying problem shifted to No. 4 and No. 1 respectivly..... So NOW THE QUESTION IS IF NTS BRACKET WAS FAULTY THEN Y IT SHIFTED TO OTHER ENGINES??? No doubt NTS may also b the reason but only for one engine not for all. Quote Link to comment Share on other sites More sharing options...

How NTS system works? Thanks Regards Munir Abbasi Home of hercules Pakistan Quote Link to comment Share on other sites More sharing options...
Moeed hassan Posted October 16, 2018 Share Posted October 16, 2018 Job guides are there for fault isolation..... Ok fine with the throttle anticepation but my question is how probkem shifted to other engines if the problem was with NTS BRACKET itself...

Moeed hassan Posted October 18, 2018 Share Posted October 18, 2018 My dear respected munir abbasi.....do u means how to consult FI according to reported defect???? Ok cool. It is pretty difficult to write it here but in short first of all u will find the FAULT CODE of your defect in the CONCERNING SYSTEM FI..... after geting code u will have to fine that code in the same FI and then u will b able to isolate that fault according to FI. I THINK IT WOULD B HELPFUL TO U. REGARDS. Quote Link to comment Share on other sites More sharing options...
