§29.1461 Equipment containing high energy rotors

(a) Equipment containing hi gh energy rot ors must meet sub-paragraphs (b), (c), or (d). (b) High energy rot ors contained in equipment must be abl e t o wi thstand dam age caused by m alfunctions, vi bration, abnorm al speeds, and abnormal temperatures. In addition: (1) Auxiliary rotor cases m ust b e ab le to contain damage caused by the failure of high energy rotor blades; and (2) Equipment control devices, systems, and instrumentation m ust reasonabl y ensure that no operating lim itations affectin g th e integrity of high energy rotors will be exceeded in service. (c) It must be shown by t est t hat equi pment containing hi gh energy rot ors can contain any failure of a hi gh energy ro tor that occurs at the highest speed obt ainable wi th t he normal speed control devices inoperative. (d) Equipment containing hi gh energy rot ors must b e lo cated wh ere ro tor failu re will neither endanger t he occupant s nor adversel y affect continued safe flight.
