Status message

There are 12 Updates appearing in the Federal Register for 14 CFR Part 23. View below or at eCFR (GPOAccess)
§ 23.937 Turbopropeller-drag limiting systems.

(a) Turbopropeller-powered airplanepropeller-drag limiting systems must be designed so that no single failure or malfunction of any of the systems during normal or emergency operation results in propeller drag in excess of that for which the airplane was designed under the structural requirements of this part. Failure of structural elements of the drag limiting systems need not be considered if the probability of this kind of failure is extremely remote.

(b) As used in this section, drag limiting systems include manual or automatic devices that, when actuated after engine power loss, can move the propeller blades toward the feather position to reduce windmilling drag to a safe level.
