CS 23.2210 Structural design loads

ED Decision 2017/013/R

(a) The applicant must:

(1) determine structural design loads resulting from likely externally or internally applied pressure, force or moment which may occur in flight, ground and water operations, ground- and water- handling, and while the aeroplane is parked or moored;

(2) determine the loads required by CS 23.2210(a)(1) at all critical combinations of parameters, on and within the boundaries of the structural design envelope; and

(3) the magnitude and distribution of these loads must be based on established physical principles within the structural design envelope.

CS 23.2215 Flight load conditions

ED Decision 2017/013/R

(a) Critical flight loads are established for symmetrical and asymmetrical loading from all combinations of airspeeds and load factors at and within the boundaries of the manoeuvre and gust envelope:

(1) at each altitude within the operating limitations, where the effects of compressibility are taken into account when significant;

(2) at each mass from the design minimum mass to the design maximum mass; and

(3) at any practical but conservative distribution of disposable load within the operating limitations for each altitude and weight.

(b) Vibration and buffeting does not result in structural damage up to dive speed.

(c) Flight loads resulting from a likely failure of an aeroplane system, component, or engine are determined.

CS 23.2230 Limit and ultimate loads

ED Decision 2017/013/R

(a) Unless special or other factors of safety are necessary to meet the requirements of this Subpart, the applicant must determine:

(1) the limit loads, which are equal to the structural design loads; and

(2) the ultimate loads, which are equal to the limit loads multiplied by a 1.5 factor of safety, unless otherwise provided.

(b) Some strength specifications are specified in terms of ultimate loads only, when permanent detrimental deformation is acceptable.
