Key Takeaways:

Part 141 flight schools operate under strict FAA-approved Training Course Outlines (TCOs) that specify authorized airports for student flights.
Diverting to an unapproved airport without prior permission invalidates that specific flight for meeting Part 141 course requirements, meaning the flight segment must be repeated.
Although the flight won't count towards the Part 141 course, the flight hours still count toward the student's total flight time, and diverting due to weather is considered good aeronautical decision-making.

Question: I am a Part 141 flight student working on my commercial certificate. I was on the solo long cross-country flight when I had to divert to another airport because of the weather. When I returned to the flight school and told my CFI what I had done, he said the flight would not count because the airport I diverted to isn’t one of the ones we’re authorized to use. How can they take that time away from me?

Answer: Part 141 flight schools operate using a highly regulated FAA-approved syllabus and Training Course Outline (TCO), which includes a list of approved airports the students can fly to. Deviating from the list without prior permission invalidates the specific flight toward meeting the requirements to complete the Part 141 course. Basically, you’ll have to repeat that cross-country flight—only this time going to an approved airport for it to count.
