ACTION: Final rule. SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2009-25-13, which applied to certain Bombardier, Inc., Model BD-100-1A10 (Challenger 300) airplanes. AD 2009-25-13 required the deactivation of the left-hand (LH) baggage bay heater mat.

This AD retains the requirements of AD 2009-25-13 and requires modifying the baggage bay sidewall interior panel, heater mat, and water tank heater installation, and doing functional testing. Upon the completion of the new actions, the retained requirements of AD 2009-25-13 will terminate. This AD also revises the applicability. The FAA is issuing this AD to address the unsafe condition on these products. DATES: This AD is effective October 23, 2024.
