Schedule 27 ATSO-C1006 — Restraint system automated release device
(subsection 13.2 (1), table, item 7)

1 Application
       This Schedule applies to an article manufacturer in relation to a restraint system automated release device.

2 Definitions
       In this Schedule:
restraint means a tether, strop, cargo tie-down, seat belt or similar device, which includes its own manual release system.
restraint system automated release device or RSARD means a device that:
(a)              is an add-on dual-purpose restraint-release device used in conjunction with a restraint and an anchor point in an aircraft; and
(b)              keeps a person or an item restrained inside the aircraft during flight; and
(c)              automatically activates to release the person or restrained item from the anchor point if the aircraft ditches or crashes into water; and
(d)              is not aircraft type specific.
RTCA/DO-160G means the RTCA Document RTCA/DO‑160G called Environmental Conditions and Test Procedures for Airborne Equipment, or a later version of RTCA Document No. DO-160, as existing from time to time.

3 Minimum performance standard — compliance with RTCA/DO-160G
       The RSARD must comply with the standards in the provision of RTCA/DO‑160G mentioned in column 2 of an item of the following table in relation to the environmental conditions mentioned in column 1 of the item.

Compliance with RTCA/DO-160G

4 Minimum performance standard — RSARD in restraint mode
       (1)The RSARD must, in restraint mode:
(a) be statically tested to its ultimate rated strength; and
(b) for the load rating test — be attached to an anchor point and restraint, using a method that replicates that likely to be found in service; and
(c) if the RSARD is designed to attach to occupant restraints:
           (i) have a load rating of at least 15 kN; and
           (ii) be designed to interface with the restraint without modification of the restraint or RSARD; and
(d) not interfere with, or modify, the attaching restraint system's normal attaching method or restraint function; and
(e) be designed so as to protect against unintentional disengagement; and
(f) not restrict the attaching restraint system's range of movement.
