63.1 General
FAR 27.301 : Loads
(a)
Strength requirements are speci.edin terms oflimitloads(the maximumloadsto be expected in service) and ultimate loads (limit loads multiplied by prescribed factors of safety).Unless otherwiseprovided,prescribedloads arelimitloads.

(b)
Unless otherwiseprovided, the speci.ed air,ground, and waterloads mustbeplaced in equilibrium with inertia forces, considering each item of mass in the rotorcraft. These loads must be distributed to closely approximate or conservatively represent actual conditions.

(c)
If de.ections under load would signi.cantly change the distribution of external or internal loads, this redistribution must be taken into account.

FAR 27.303 : Factor of safety
Unless otherwiseprovided, afactor of safety of1.5 mustbe used.Thisfactor applies to external and inertia loads unless its application to the resulting internal stresses is more conservative.
FAR 27.305 : Strength and deformation
(a)
The structure mustbe able to supportlimit loads withoutdetrimental orpermanent deformation.At anyload up tolimitloads,thedeformationmay notinterferewith safe operation.

(b)
The structure must be able to support ultimate loads without failure. This must be shown by–

(1)
Applying ultimate loads to the structure in a static test for at least three seconds; or
