SUPPLEMENTARY INFORMATION: The substance of these special conditions has been published in the Federal Register for public comment in several prior instances with no substantive comments received. Therefore, the FAA has determined that prior public notice and comment are unnecessary, and finds that, for the same reason, good cause exists for adopting these special conditions upon publication in the Federal Register. Comments Invited We invite interested people to take part in this rulemaking by sending written comments, data, or views. The most helpful comments reference a specific portion of the special conditions, explain the reason for any recommended change, and include supporting data. We will consider all comments we receive by the closing date for comments. We may change these special conditions based on the comments we receive. Background On May 30, 2012, Bombardier applied for an amendment to Type Certificate No. T00003NY to include the new BD-700-2A12 and BD-700-2A13 airplanes. The Model BD-700-2A12 and BD-700-2A13 airplanes, which are derivatives of the BD-700 series airplane currently approved under Type Certificate No. T00003NY. The Model BD-700-2A12 and BD-700-2A13 airplanes augment the existing BD-700 family of airplanes and are marketed as the Bombardier Global 7000 and Global 8000 airplanes, respectively. These are business jets with a maximum certified passenger capacity of 19. The Model BD-700-2A12 and BD-700-2A13 airplanes will have a maximum takeoff weight of 106,250 lbs. and 104,800 lbs., respectively. Type Certification Basis Under the provisions of title 14, Code of Federal Regulations (14 CFR) 21.101, Bombardier must show that the Model BD-700-2A12 and BD- 700-2A13 airplanes meet the applicable provisions of the regulations listed in Type Certificate No. T00003NY or the applicable regulations in effect on the date of application for the change except for earlier amendments as agreed upon by the FAA. If the Administrator finds that the applicable airworthiness regulations (i.e., 14 CFR part 25) do not contain adequate or appropriate safety standards for the Model BD-700-2A12 and BD-700-2A13 airplanes because of a novel or unusual design feature, special conditions are prescribed under the provisions of Sec. 21.16. Special conditions are initially applicable to the model for which they are issued. Should the type certificate for that model be amended later to include any other model that incorporates the same novel or unusual design feature, or should any other model already included on the same type certificate be modified to incorporate the same novel or unusual design feature, these special conditions would also apply to the other model under Sec. 21.101. In addition to the applicable airworthiness regulations and special conditions, the Model BD-700-2A12 and BD-700-2A13 airplanes must comply with the fuel-vent and exhaust-emission requirements of 14 CFR part 34 and the noise-certification requirements of 14 CFR part 36. The FAA issues special conditions, as defined in 14 CFR 11.19, in accordance with Sec. 11.38, and they become part of the type certification basis under Sec. 21.101. Novel or Unusual Design Features The Bombardier Model BD-700-2A12 and BD-700-2A13 airplanes will incorporate the following novel or unusual design feature: New control architecture and a full digital-flight-control system that provides comprehensive flight-envelope protections. Discussion The applicable airworthiness regulation is 14 CFR 25.143. The purpose of Sec. [thinsp]25.143 is to verify that any operational maneuvers conducted within the operational envelope can be accomplished smoothly with average piloting skill and without exceeding any structural limits. The pilot should be able to predict the airplane response to any control input. During the course of the flight test program, the pilot determines compliance with Sec. [thinsp]25.143 primarily through qualitative methods. During flight test, the pilot should evaluate all of the following: The interface between each protection function; Transitions from one mode to another; Airplane response to intentional dynamic maneuvering, whenever applicable, through dedicated maneuvers; General controllability assessment; High speed characteristics; and High angle-of-attack. Section 25.143, however, does not adequately ensure that the novel or unusual features of the BD-700 series airplanes will have a level of safety equivalent to that of existing standards. These special conditions are therefore required to accommodate the flight envelope limiting systems in the BD-700 series airplanes. The general limiting requirements are necessary to ensure a smooth transition from normal flight to the protection mode and adequate maneuver capability. The general limiting requirements also ensure that the structural limits of the airplane are not exceeded. Furthermore, failure of the flight- envelope protection feature must not create hazardous flight conditions. The additional safety standards in these special conditions will ensure a level of safety equivalent to that of existing standards. Applicability As discussed above, these special conditions are applicable to the Bombardier Model BD-700-2A12 and BD-700-2A13 airplanes. Should Bombardier apply at a later date for a change to the type certificate to include another model incorporating the same novel or unusual design feature, these special conditions would apply to that model as well. Conclusion This action affects only certain novel or unusual design features on Bombardier Model BD-700-2A12 and BD-700-2A13 airplanes. It is not a rule of general applicability.

The Special Conditions Accordingly, pursuant to the authority delegated to me by the Administrator, the following special conditions are issued as part of the type certification basis for Bombardier Model BD-700-2A12 and BD- 700-2A13 airplanes. General Limiting Requirements a. Onset characteristics of each envelope protection feature must be [[Page 12254]] smooth, appropriate to the phase of flight and type of maneuver, and not in conflict with the ability of the pilot to satisfactorily change airplane flight path, speed, or attitude as needed. b. Limit values of protected flight parameters (and if applicable, associated warning thresholds) must be compatible with the following: i. Airplane structural limits, ii. Required safe and controllable maneuvering of the airplane, and iii. Margins to critical conditions. Unsafe flight characteristics/ conditions must not result if dynamic maneuvering, airframe and system tolerances (both manufacturing and in-service), and non-steady atmospheric conditions, in any appropriate combination and phase of flight, can produce a limited flight parameter beyond the nominal design-limit value. c. The airplane must be responsive to intentional dynamic maneuvering to within a suitable range of the parameter limit. Dynamic characteristics such as damping and overshoot must also be appropriate for the flight maneuver and limit parameter in question. d. When simultaneous envelope limiting is engaged, adverse coupling or adverse priority must not result. Failure States a. Electronic flight-control-system failures (including sensors) must not result in a condition where a parameter is limited to such a reduced value that safe and controllable maneuvering is no longer available. b. The crew must be alerted by suitable means if any change in envelope limiting or maneuverability is produced by single or multiple failures of the electronic flight-control system not shown to be extremely improbable. Issued in Des Moines, Washington, on March 15, 2018. Victor Wicklund, Manager, Transport Standards Branch, Policy and Innovation Division, Aircraft Certification Service.
