14 C.F.R. § 450.121

Current through October 31, 2024
Section 450.121 - Debris analysis
(a)General. A flight safety analysis must include an analysis characterizing the hazardous debris generated from normal and malfunctioning vehicle flight as a function of vehicle flight sequence.
(b)Vehicle impact and breakup analysis. A debris analysis must account for:
(1) Each reasonably foreseeable cause of vehicle breakup and intact impact,
(2) Vehicle structural characteristics and materials, and
(3) Energetic effects during break-up or at impact.
(c)Propagation of debris. A debris analysis must compute statistically valid debris impact probability distributions. The propagation of debris from each predicted breakup location to impact must account for-
(1) All foreseeable forces that can influence any debris impact location; and
(2) All foreseeable sources of impact dispersion, including, at a minimum:
(i) The uncertainties in atmospheric conditions;
(ii) Debris aerodynamic parameters, including uncertainties;
(iii) Pre-breakup position and velocity, including uncertainties; and
(iv) Breakup-imparted velocities, including uncertainties.
(d)Application requirements. An applicant must submit:
(1) A description of all scenarios that can lead to hazardous debris;
(2) A description of the methods used to perform the vehicle impact and breakup analysis, in accordance with § 450.115(c) ;
(3) A description of the methods used to compute debris impact distributions, in accordance with § 450.115(c) ;
(4) A description of the atmospheric data used as input to the debris analysis; and
(5) A quantitative description of the physical, aerodynamic, and harmful characteristics of hazardous debris.
