Text in force at CS29-12: from CS29-0, effective 14 Nov 2003.
For each fitting (part or term inal used to j oin one structural member to another) the following apply:
(a) For each fitting whose strength is not proven by lim it and ultim ate load tests in which actual stress conditions are sim ulated in the fitting and surrounding structures, a fitting factor of at least 1.15 must be applied to each part of:
(1) The fitting;
(2) The means of attachment; and
(3) The bearing on the joined members.
(b) No fitting factor need be used:
(1) For joints m ade under approved practices and based on com prehensive test data (such as continuous joints in metal plating, welded joints, and scarf joints in wood); and
(2) With respect to any bearing surface for which a larger special factor is used.
(c) For each integral fitting, the part must be treated as a fitting up to the point at which the section properties become typical of the member.
(d) Each seat, berth, litter, safety belt, and harness attachment to the structure m ust be shown by analysis, tests, or both, to be able to withstand the inertia forces prescribed in CS 29.561(b)(3) multiplied by a fitting factor of 1.33.
