Ladies and Gents,
I can see both sides of the argument here, but as I am on sick leave, I can't get near a Maintenance Manual for my own investigation. Can someone possibly produce a Maintenance Manual reference for all to see and read. I would assume different engine manufacturers/companies would have different procedures.
GasBags, with respect, is it possible that you are quoting a company procedure and not Maintenance Manual?
