Airworthiness Directive · Amendment 39-18594 · Doors
Bombardier, Inc. Airplanes
This AD applies to Bombardier Inc. Model BD-700-1A10 and BD-700-1A11 airplanes, certificated in any category, serial numbers (S/Ns) 9002 through 9515 inclusive and S/N 9998.
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model BD-700-1A10 and BD-700-1A11 airplanes. This AD was prompted by reports of operator inability to open the main passenger door following severe hot soak conditions. This AD requires the incorporation of a new configuration to the passenger door external handle detent to enhance the performance across the full range of the airplane operating temperatures. We are issuing this AD to prevent thermal expansion and permanent deformation at severe hot soak conditions, creating high friction between the spring pot housing and the slider that could result in inability to open the main passenger door and impede evacuation in the event of an emergency.
Within 15 months after the effective date of this AD, incorporate the new configuration to the passenger door external handle detent, in accordance with the Accomplishment Instructions of the applicable service information identified in paragraphs (g)(1) through (g)(4) of this AD:
(1) Bombardier Service Bulletin 700-1A11-52-021, Revision 01, dated February 3, 2015 (for Model BD-700-1A11 airplanes).
(2) Bombardier Service Bulletin 700-52-044, Revision 01, dated February 3, 2015 (for Model BD-700-1A10 airplanes).
(3) Bombardier Service Bulletin 700-52-5008, Revision 01, dated February 3, 2015 (for Model BD-700-1A11 airplanes).
(4) Bombardier Service Bulletin 700-52-6008, Revision 01, dated February 3, 2015 (for Model BD-700-1A10 airplanes).
