Bombardier Jets Need Screw Fixes: FAA's Landing Safety Mandate
Published Date: 4/3/2026
Rule
Summary
The FAA is making a new rule for Bombardier airplanes to fix a problem where the nose wheel steering can act up during landing. Owners of certain Bombardier CL-600 models must replace specific screws in the nosewheel steering system and update their maintenance plans by May 8, 2026. This keeps flights safe and avoids costly repairs down the road.
Analyzed Economic Effects
3 provisions identified: 1 benefits, 2 costs, 0 mixed.
Required maintenance program update
Operators must revise their maintenance or inspection program within 60 days after May 8, 2026 to incorporate the specified Bombardier temporary revisions. The FAA estimates revising the program takes 90 work-hours per operator at $85/hour for an average cost of $7,650 per operator.
Preventing runway excursion risk
The AD addresses reports of uncommanded nosewheel steering caused by loose setscrews that, if not fixed, could lead to a runway excursion. Replacing the setscrews and updating life limits in maintenance programs aims to reduce that safety risk.
Mandatory setscrew replacement deadline
If you operate the affected Bombardier CL-600 series airplanes, you must replace the nosewheel steering rudder pedal potentiometer universal coupling setscrews within 36 months or 1,400 flight hours, whichever occurs first, after the AD effective date of May 8, 2026. The FAA estimates the per-airplane work is 4 work-hours at $85/hour plus $40 parts for a total of $380 per airplane, and the AD applies to 930 U.S.-registered airplanes.
