CS 27.727 Reserve
energy absorption drop test
ED Decision 2003/15/RM
The reserve energy absorption drop test must be conducted as follows:
(a) The drop height must be 1.5 times that specified in CS 27.725(a).
(b) Rotor lift, where considered in a manner similar to that prescribed in CS 27.725(b), may not exceed 1.5 times the lift allowed under that paragraph.
(c) The landing gear must withstand this test without collapsing. Collapse of the landing gear occurs when a member of the nose, tail, or main gear will not support the rotorcraft in the proper attitude or allows the rotorcraft structure, other than the landing gear and external accessories, to impact the landing surface.
