US-FAA14 CFR 135.299

Pilot in command: Line checks: Routes and airports

Read the official rule

In 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.
