Log book entrys
On the bottom of all log book certificates you should find a statment that the certificate should be attached to the aproprate log book page.
LAMS and now LAMP require that you use some form of record keeping as IO540 states they can be a pile of paper records but in the long run using the "industry standard" logbooks will save you time and trouble.
I find the whole practice very messy and logbooks with years of these certificates are very hard to read, some may go missing and handwriten entrys are even worse (my handwriting included). For me the answer is the large sticky lable, entrys cant go missing and every one can read my typing not to mention the spellcheck!
As to the origanal subject of the text if MAGS21 would like to PM me I will try to advise him on a way forward that will result in an outcome that both himself and the engineer can live with.
