ED Decision 2009/005/R
Parts the failure of which could adversely affect safety must be suitably protected against deterioration or loss of strength in service due to weathering, corrosion, heat, abrasion, ground handling, ground transport, flight conditions or other causes. (See AMC 31HB.39)
ED Decision 2009/005/R
ED Decision 2009/005/R
Suspension system cables and components manufactured from stainless steels (corrosion resistant steels) are considered compliant with this requirement.
To ensure the suitable protection of parts against deterioration or loss of strength, it is permissible to rely on instructions for continued airworthiness (e.g. recommended inspections or mandatory replacement of parts) (See also CS 31HB.82).
