Airworthiness Directive · Amendment 39-22810 · Equipment/furnishings
Bombardier, Inc. Airplanes
This AD applies to Bombardier, Inc., Model BD-100-1A10 airplanes, certificated in any category, serial numbers 20003 through 20364 inclusive, 20366, 20367, 20369, and 20372.
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. 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 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.
This paragraph restates the requirements of paragraph (g) of AD 2009-25-13, with no changes.
