(a) CS 27.562(a) Amdt. 6 is accepted as a means of compliance.
(b) CS 27.562(b) Amdt. 6 is accepted as a means of compliance under the following conditions:
(1) CS 27.562(b)(1) Amdt. 6 is accepted as a means of compliance, noting that the 30 g at seat attachment level was based upon the typical underfloor structure of a conventional rotorcraft. Therefore the 30 g is only valid if the structure underneath the seats has equal or better damping characteristics than a conventional rotorcraft. If specific design features are integrated, less than 30g at the seat may be acceptable based on analysis supported by tests
(2) CS 27.562(b)(2) Amdt. 6 is accepted as a means of compliance with the following addition: For CTOL peak floor deceleration should occur in not more than 0.05 seconds after impact and should reach a minimum of 26 g. For CTOL seat/restraint systems not being in the first row, peak deceleration should occur in not more than 0.06 seconds after impact and should reach a minimum of 21 g.
(3) CS 27.562(b)(3) Amdt. 6 is accepted as a means of compliance.
(c) CS 27.562(c) Amdt. 6 is accepted as a means of compliance.
(d) CS 27.562(d) Amdt. 6 is accepted as a means of compliance.
