Tiny Screws Threaten Bombardier Landings: FAA Demands Replacements

Published Date: 8/12/2025

Proposed Rule

Summary

If you fly a Bombardier CL-600 series plane, listen up! The FAA wants to fix a nose wheel steering problem by replacing some tiny screws and updating maintenance rules. This keeps landings safe and smooth, so owners should act soon to avoid costly issues.

Analyzed Economic Effects

2 provisions identified: 0 benefits, 2 costs, 0 mixed.

Mandatory Setscrew Replacement on CL-600 Series

If you operate a Bombardier CL-600-1A11 (600), CL-600-2A12 (601), or CL-600-2B16 (601-3A, 601-3R, and 604 Variants) airplane, the FAA proposes you must replace the nosewheel steering potentiometer universal coupling setscrews. The rule is proposed to address uncommanded nose wheel steering that occurred on landing.

New Maintenance Life Limits Required

The FAA proposes you must revise the existing maintenance or inspection program to add new life limits for the nosewheel steering potentiometer universal coupling setscrews for the same Bombardier CL-600 series models. The revision requirement applies “as applicable” to existing maintenance programs for those airplanes.
