(1)
Auxiliary rotor cases must be able to contain damage caused by the failure of high energy rotorblades; and

(2)
Equipment controldevices,systems,andinstrumentationmust reasonably en-surethat no operatinglimitations a.ecting theintegrity ofhigh energy rotors will be exceeded in service.

(c)
It must be shown by test that equipment containing high energy rotors can contain any failure of a high energy rotor that occurs at the highest speed obtainable with the normal speed control devices inoperative.

(d)
Equipment containing high energy rotors must be located where rotor failure will neither endanger the occupants nor adversely a.ect continued safe .ight.]

77.1 Operating Limitations
FAR 29.1503 : Airspeed limitations : general.
(a)
An operating speed range must be established.

(b)
When airspeed limitations are a function of weight, weight distribution, altitude, rotor speed, power, or other factors, airspeed limitations corresponding with the critical combinations of these factors must be established.

FAR 29.1505 : Never-exceed speed.

(a)
The never-exceed speed, VNE, must be established so that it is–

(1)
Notlessthan40knots(CAS); and

(2)
Not more than the lesser of–
