Airworthiness Directives; Bombardier, Inc., Airplanes
Abstract
The FAA proposes to supersede Airworthiness Directive (AD) 2009-25-13, which applies to certain Bombardier, Inc., Model BD-100- 1A10 (Challenger 300) airplanes. AD 2009-25-13 requires the deactivation of the left-hand (LH) baggage bay heater mat. Since the FAA issued AD 2009-25-13, Bombardier developed a new design solution for the potential uncontrolled heating of the baggage bay sidewall heater mat. This proposed AD would retain the requirements of AD 2009- 25-13, and would also require 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 would terminate. This proposed AD would also revise the applicability and prohibit the installation of affected parts. The FAA is proposing this AD to address the unsafe condition on these products.
Applicability
Aircraft makes and models this AD applies to, sorted by US-registered fleet size.

Upon the completion of the new actions, the retained requirements of AD 2009-25-13 would terminate. This proposed AD would also revise the applicability and prohibit the installation of affected parts. The FAA is proposing this AD to address the unsafe condition on these products.
