Safety Management Systems used to be something only airlines had to have. In 2024, the FAA made SMS mandatory for Part 135 charter operators too. Here's that history, and why Part 61 and Part 141 flight schools are worth watching next, even before anything is final.
A little over a decade ago, a Safety Management System was an airline-only requirement. Part 135 charter and on-demand operators could build one if they wanted to (the FAA even had a voluntary acceptance process for it), but nothing in the regulations required it. That changed in 2024. And the conversation now happening around Part 141 flight schools looks a lot like the one Part 135 operators were having a few years before their mandate arrived.
This isn’t a claim that flight school SMS is about to become mandatory. It isn’t, not yet, and there’s no rule on the books that says it will be. It’s a look at how the SMS mandate has actually expanded so far, what’s currently on the table for flight training, and why building a real safety program now is a reasonable bet regardless of how that plays out.
14 CFR Part 5 is the regulation that governs Safety Management Systems. Its scope has changed exactly once since it was written for Part 121, and operators who had already been running one voluntarily had a head start when it did.
| When | What changed |
|---|---|
| 2006–2015 | Voluntary era for Part 121. Airlines could adopt SMS through FAA guidance and pilot programs; nothing in the regulations required it yet. |
| January 2015 | FAA finalizes 14 CFR Part 5, requiring every Part 121 air carrier to implement an SMS, phased in over the following years. |
| 2015–2024 | Voluntary era for everyone else. Part 135 charter operators, Part 91.147 air tour operators, and Part 21 manufacturers could pursue SMS acceptance under AC 120-92 (many did), but none were required to. |
| April 26, 2024 | FAA publishes a final rule extending the Part 5 mandate to Part 135 operators, Part 91.147 Letter-of-Authorization holders, and certain Part 21 certificate holders, effective May 28, 2024. |
| May 28, 2027 | Compliance deadline. Part 135 and 91.147 operators must have an SMS implemented and a declaration of compliance submitted to the FAA. |
| 2026 → ongoing | Under review, not yet a rule. An industry report recommends extending SMS (alongside a related quality-management framework) to Part 141 flight schools as part of a broader FAA Part 141 modernization effort. No proposed rule has been published and no compliance date exists. |
Sources: 14 CFR Part 5 as amended April 26, 2024; FAA Safety Management Systems Final Rule; National Flight Training Alliance, Part 141 Aviation Training Modernization Report, submitted to the FAA March 31, 2026. This is general information, not legal advice.
Notice the shape of it. The one expansion of the SMS mandate that has actually happened followed a consistent pattern: a long voluntary period that only some operators bothered with, then a final rule that made it mandatory for that category, then a multi-year runway to comply. Part 135 operators got roughly a decade of “voluntary” before 2024, and still have until 2027 to finish complying. Whether flight schools get a similar runway, a shorter one, or none at all, isn’t something anyone can promise. But the pattern is real, and it’s the reason this is worth paying attention to now instead of after a rule is actually proposed.
In March 2026, the National Flight Training Alliance submitted a 471-page report to the FAA proposing a significant overhaul of Part 141, the certification framework most structured flight schools operate under. Safety Management Systems and Quality Management Systems are part of that package: a tiered framework in which a school’s documented processes, and eventually its measurable safety and training outcomes, would factor into whether it keeps its examining authority, the privilege of certifying its own students for checkrides.
The FAA opened that report for public comment, which has since closed. The agency has said it will issue a findings report later in 2026 describing which parts of the modernization package it intends to pursue, after which any actual rule change would go through formal rulemaking, its own public comment period, and its own compliance timeline, similar to the process Part 135 went through on the way to its 2024 rule.
Nothing here is final. There is no proposed rule with a docket number yet, no comment period on an actual rule (as opposed to the industry report that recommends one), and no compliance date. It is genuinely possible this moves slowly, gets scaled back, or the SMS piece gets separated from the rest of the modernization package. It’s also possible it doesn’t. Either way, this is roughly where Part 135 operators stood a few years before 2024: some used that lead time to build a real safety program, and some didn’t.
“Not required yet” isn’t the same as “not worth doing yet.” A few reasons it’s worth building the habit before anyone tells you to:
I’m Safe SMS was built first for Part 61 and Part 141 flight schools. It’s a real safety program, not just a compliance placeholder to point to later:
Pricing is $35 per aircraft per month, all-inclusive, with a one-time setup fee: the same model whether the school runs two aircraft or twenty. There’s no per-user charge, so adding instructors and students to the account doesn’t change the price.
Not yet. 14 CFR Part 5 currently requires SMS for Part 121 air carriers, Part 135 operators, Part 91.147 air tour Letter-of-Authorization holders, and certain Part 21 certificate holders. Part 61 and Part 141 flight schools are not currently required to have an SMS. A March 2026 industry report proposes extending SMS and quality-management requirements to Part 141 schools as part of a broader FAA Part 141 modernization effort, but no rule has been proposed and no compliance date exists as of this writing.
Yes. The FAA’s April 2024 final rule extended the 14 CFR Part 5 SMS mandate to Part 135 commuter and on-demand operators, effective May 28, 2024. Existing Part 135 operators have until May 28, 2027 to implement an SMS and submit a declaration of compliance. Before that rule, SMS was voluntary for Part 135 operators.
It isn’t guaranteed. What exists today is an industry report, submitted to the FAA in March 2026 by the National Flight Training Alliance, recommending SMS and QMS as part of a Part 141 modernization package, plus a public comment period that has since closed. The FAA has said it will issue a findings report describing which parts of the package it intends to pursue, after which formal rulemaking (with its own comment period and compliance timeline) would follow. Nothing is final, and it could take years, if it happens at all.
I’m Safe SMS is $35 per aircraft per month, all-inclusive, billed monthly or annually, plus a one-time setup fee. There is no per-user charge: pricing scales with the size of the fleet, not the number of instructors or students using it.
