Part 121 · Duty, rest & fatigue
FAR 121.467 cabin-crew enforcer
Flight attendants get the same assignment-time duty/rest enforcement on the 121.467 regime that pilots get on 117, so cabin-crew legality is held to the same standard rather than tracked separately. It replaces the parallel FA duty spreadsheet.
Launching the first quarter of 2027.
Illustrative — every screen reflects your own data.
Who it's for
Crew schedulers who assign flight attendants and need cabin-crew duty/rest held to the same assignment-time standard as the flight crew they fly with.
What it replaces
The parallel flight-attendant duty spreadsheet kept off to the side of the pilots' tracking.
What far 121.467 cabin-crew enforcer gives you
- Assignment-time duty/rest enforcement for flight attendants
- The 121.467 regime, parallel to pilots' 117
- Cabin-crew legality held to the same standard, not tracked separately
The cabin-crew counterpart to the 117 check
Flight attendants get the same assignment-time duty/rest enforcement on the FAR 121.467 regime that pilots get on 117 — so a cabin-crew assignment that would bust the limits is blocked at assignment time, the same way a pilot's is. For the standard 14-hour duty tier, the 121.467 enforcer is the cabin-crew counterpart to the 117 check; the extended-duty and augmented-crew tiers exist in the engine but no caller sets them yet, so coverage today is the base tier.

- A legal assignment posts; one that would bust the limits is blocked
Cabin-crew legality in the platform, not on a side sheet
Because cabin-crew legality runs through the platform rather than a parallel spreadsheet, it's held to the same standard as the flight crew it flies with rather than tracked off to the side. Cabin crew aren't managed on a separate FA duty spreadsheet.

For the standard 14-hour duty tier, the 121.467 enforcer is the cabin-crew counterpart to the 117 check, not a watered-down version of it — the extended-duty (16h) and augmented-crew tiers exist in the engine but aren't wired up by any caller yet, so today's enforcement covers the base tier, not every tier the regulation defines.

How it works
FAR 121.467 cabin-crew enforcer, step by step
Assign a flight attendant to a trip.
The 121.467 duty/rest limits are checked at assignment time, parallel to pilots' 117.
A legal assignment posts; one that would bust the limits is blocked.
Cabin-crew legality lives in the platform, not a separate FA duty spreadsheet.
Questions
FAR 121.467 cabin-crew enforcer — frequently asked
Does it enforce flight-attendant duty and rest too?
Yes. Flight attendants get the same assignment-time enforcement on the FAR 121.467 regime that pilots get on FAR 117, so cabin-crew legality is held to the same standard rather than tracked separately.
Is FA legality tracked separately from pilots'?
No. The 121.467 enforcer runs through the platform alongside the pilots' 117 check, so cabin crew aren't managed on a parallel spreadsheet.
