🇬🇧 English

The FAA is requiring inspections of certain Bell 429 helicopters due to a safety issue with incorrectly installed lockwire. Operators of Bell Textron Model 429 helicopters must inspect the stability control system actuator and fix any improperly installed lockwire, plus affected parts can't be reinstalled without meeting specific conditions. This affects helicopter operators, maintenance crews, and Bell 429 fleet owners. Improperly secured flight control components could lead to loss of helicopter control, making this a critical safety fix.
