“It’s not what you don’t know that kills you, it’s what you know for sure that ain’t true.” – Mark Twain
If we worked between the aircraft’s painted walking lines or below 10 feet in height, no fall protection was needed. As an aircraft maintainer, you were trained to know and follow the rules.
We were wrong.
Federal law had updated height requirements in the mid-1990s and we were ignorant.
Then someone asked, “Are we sure?”
You’ve met this type of person. They’ll speak up in a meeting when everything is going great. They’ll ask, “Why?”, “Is it still true?”, and “Should we continue this way?”
And eyes will roll.
That is when Mark Twain would whisper, “Ignore this voice at your own peril.”
The trust your organization places in you is based on professionalism. Professionals never stop learning, growing, and questioning.
Listen to this voice.
