About National Checklist Day
National Checklist Day is an informal U.S. observance held on October 30.
An FAA Safety Briefing article notes the observance and links the date to a 1935 aviation accident that helped drive the development of formal flight checklists.
Why National Checklist Day matters
The day highlights checklists as practical tools for remembering and verifying important steps in complex work and ordinary routines.
A checklist is an aid, not a substitute for training, judgment, professional procedures or legally required safety systems.
History of National Checklist Day
On October 30, 1935, Boeing’s Model 299 crashed after the crew failed to disengage gust locks before takeoff.
The FAA article explains that the aircraft’s complexity prompted creation and mandatory use of a checklist, helping establish the checklist as an aviation safety tool.
The same FAA article says National Checklist Day rolls around every October 30, while also noting that it has not inspired an annual proclamation.

How to Observe National Checklist Day
Make a short checklist for a routine task where forgetting a step would cause inconvenience or rework.
Review an existing personal or team checklist and remove vague, duplicate or outdated items.
For aviation, medicine, industrial work or other regulated activities, use the approved procedures and checklists for that setting rather than creating a casual substitute.
Treat checklists as practical memory aids; do not use them to label ordinary forgetfulness as a medical or mental-health condition.
