Marking of break-in points
70.—(1)  An operator of a Singapore registered aircraft with an MCTOM exceeding 3,600 kg must ensure that every area of the aircraft fuselage suitable for break‑in by rescue crews in the event of an emergency (called in this regulation a break‑in area) —
(a)is rectangular in shape;
(b)is marked on the exterior surface of the aircraft’s fuselage by right‑angled corner markings, each arm of which is 10 cm in length along its outer edge and 3 cm in width; and
(c)is marked across the centre with the words “CUT HERE IN EMERGENCY”.
(2)  Where a break-in area marked in accordance with paragraph (1) has corner markings that are more than 2 m apart, the operator mentioned in paragraph (1) must ensure that intermediate lines 10 cm in length and 3 cm in width are marked on the break‑in area such that the distance between adjacent markings does not exceed 2 m.
(3)  The operator mentioned in paragraph (1) must ensure that every marking required under this regulation —
(a)is red in colour; and
(b)in any case in which the colour of the adjacent background renders the red markings not readily visible, is outlined in white or some other contrasting colour in such a manner as to render the marking readily visible.
(4)  The operator mentioned in paragraph (1) must ensure that every marking required under this regulation —
(a)is painted or affixed by other equally permanent means; and
(b)is kept clean and unobscured at all times.
