AMC 27.783 Doors ED Decision 2018/007/R This AMC provides further guidance and acceptable means of compliance to supplement FAA AC 27-1B AC 27.783 § 27.783 to meet EASA’s interpretation of [CS 27.783](#_DxCrossRefBm472493373). As such it should be used in conjunction with the FAA AC but take precedence over it, where stipulated, in the showing of compliance. Specifically, this AMC addresses one area where the FAA AC has been deemed by EASA as being at variance to EASA’s interpretation. This area is as follows: (a) Explanation […] (4) Any means of egress (door, hatch, openable window) intended for use following ditching need not have a threshold above the waterline of the rotorcraft in calm water. However, the usability of the egress means should be substantiated in all sea conditions up to and including those chosen for showing compliance with [CS 27.801(e)](#_DxCrossRefBm472493312) or [27.802(c)](#_DxCrossRefBm472493311) as appropriate. See also [AMC 27.801](#_DxCrossRefBm472493376) paragraph (b)(10) and [AMC 27.802](#_DxCrossRefBm472493375) paragraph (b)(7).
