FAA Issues Directives for Regional Jet Gear Inspections
Published Date: 7/1/2025
Rule
Summary
The FAA is making new rules for certain MHI RJ Aviation regional jets because a warning showed up about worn parts in the plane’s stabilizer system. Pilots and maintenance crews must check and replace these worn parts to keep flights safe. These changes need to happen soon to avoid any safety risks and keep the planes flying smoothly.
Analyzed Economic Effects
2 provisions identified: 0 benefits, 0 costs, 2 mixed.
Mandatory inspection and replacement
Operators and maintenance crews must inspect the rubber bull gear (RBG) wheel part numbers and do on-condition replacement of affected RBG wheels in the horizontal stabilizer trim actuator (HSTA) on these models: CL-600-2C10 (Regional Jet Series 700, 701, & 702), CL-600-2C11 (Series 550), CL-600-2D15 (Series 705), CL-600-2D24 (Series 900), and CL-600-2E25 (Series 1000). The rule was issued after a STAB TRIM caution and a repair found prematurely worn teeth on an RBG wheel. This AD requires these inspections and replacements to address the unsafe condition and keep the airplanes airworthy.
Prohibition on installing affected parts
The AD prohibits installing affected RBG wheels under certain conditions on the same listed MHI RJ models. This means operators and maintenance shops cannot put the specified worn or otherwise-affected RBG wheels back into service when the prohibition applies.
