The rotorcraft must be designed for—
(a)A limit maneuvering load factor ranging from a positive limit of 3.5 to a negative limit of −1.0; or
(b)Any positive limit maneuvering load factor not less than 2.0 and any negative limit maneuvering load factor of not less than −0.5 for which—
(1)The probability of being exceeded is shown by analysis and flight tests to be extremely remote; and
(2)The selected values are appropriate to each weight condition between the design maximum and design minimum weights. [Amdt. 27-26, 55 FR 7999, Mar. 6, 1990]
