AD 2024-07-09 Airworthiness Directives; Bombardier, Inc., Airplanes
Models named: BD-700-1A10, BD-700-1A11. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
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 60065 inclusive.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
Within 30 days after the effective date of this AD, revise the existing maintenance or inspection program, as applicable, to use the information specified in Aircraft Maintenance Manual (AMM) Task 52-11-00-720-801, “Functional Test of the Passenger Door Mechanism,” Subject 52-11-00, “Passenger Door,” Chapter 52, “Doors,” of the applicable AMMs identified in figure 1 to paragraph (g) of this AD, when performing time limited maintenance check item 52-11-00-201. Figure 1 to Paragraph (g)—Bombardier AMM ER13MY24.113
Unsafe condition
This AD was prompted by the discovery that existing maintenance tasks do not detect the potential failure of the passenger door detent mechanism because there is no procedure for inspecting the passenger door locking mechanism. The FAA is issuing this AD to address potential failures of the uninspected detents (external handle detent and torque tube detent) in combination with a failure of the tension pot spring assembly. The unsafe condition, if not addressed, could result in the main passenger door opening during unpressurized flight.
Affected ADs
None.
