ED Decision 2023/013/R
STANDARD PARTS
(a) In this context, a part is considered as a âstandard partâ where it is designated as such by the design approval holder or declarant responsible for the product or part in which the part is intended to be used. In order to be considered a âstandard partâ, all design, manufacturing, inspection data and marking requirements necessary to demonstrate conformity of that part should be in the public domain and published or established as part of officially recognised standards; or
(b) For sailplanes and powered sailplanes, where it is a non-required instrument and/or equipment certified under CS 22.1301(b), if that instrument or equipment, when installed, functioning, functioning improperly or not functioning at all, does not in itself, or by its effect upon the sailplane and its operation, constitute a safety hazard.
âRequiredâ in the term ânon-requiredâ as used in point (b) means required by the applicable certification specifications (CS 22.1303, CS 22.1305 and CS 22.1307) or required by the relevant operating regulations and the applicable rules of the air, or as required by air traffic management (e.g. a transponder in certain controlled airspace).
Examples of equipment which can be considered âstandard partsâ are electrical variometers, bank/slip indicators ball type, total energy probes, capacity bottles (for variometers), final glide calculators, navigation computers, data logger / barograph / turnpoint camera, bug wipers and anti-collision systems.
Equipment which must be approved in accordance with the applicable certification specifications shall comply with the applicable ETSO or equivalent, and is not considered a âstandard partâ (e.g. oxygen equipment).
