Final inspection with Lucio on the work done. Lucio confirmed work was done well. I reported the error we made together riveting one elevator horn upside down.....He almost fainted and when i explained that i drilled out the rivets and riveted together the horn alone he wanted to check the result....As one rivet didn't look perfect we drilled it out and replaced, however the result didn't improve significantly. We resolved to keep it as it was.
