Airworthiness Directive · Amendment 39-22014 · Indicating/recording system
Bell Textron Canada Limited Helicopters
This AD applies to Bell Textron Canada Limited Model 429 helicopters, certificated in any category, serial numbers 57001 through 57369 inclusive, 57371, and 57373.
The FAA is adopting a new airworthiness directive (AD) for certain Bell Textron Canada Limited Model 429 helicopters. This AD was prompted by in-service reports of the loss of display and subsequent recovery of certain display units (DUs). This AD requires revising the existing rotorcraft flight manual supplement (RFMS) for your helicopter and disabling the traffic alert and collision avoidance system (TCAS) POP-UP feature for certain DUs. The FAA is issuing this AD to address the unsafe condition on these products.
Within 30 days after the effective date of this AD: Revise the Types of Operation—Limitations (section 1-3-A.) of the existing RFMS for your helicopter to include the information in the “Limitations” specified in figure 1 to paragraph (g) of this AD, revise the Configuration (section 1-5.) of the existing RFMS for your helicopter to include the information in the “Configuration” specified in figure 2 to paragraph (g) of this AD, and revise the Emergency and Malfunction Procedures (section 3) of the existing RFMS for your helicopter to include the information in the “CENTER DU FAILURE (RK CONFIGURATION)” specified in figure 3 to paragraph (g) of this AD.
