US-FAA14 CFR 135.299
Pilot in command: Line checks: Routes and airports
Read the official ruleIn plain English
Pilot-in-command line checks: each PIC must pass a line check — an over-the-route check of their ability to perform a typical flight, including normal and emergency procedures — at least every 12 calendar months.
Key points
- PIC line check every 12 calendar months.
- Flown over a typical route in normal line operations.
- Separate from the 135.293 competency check.
Common pitfalls
- Confusing the line check with the competency check — both are required.
