S25.1 General ED Decision 2017/015/R (a) Applicability: unless otherwise specified within, the requirements of this Appendix are applicable to the passenger or crew compartments (interiors) of: (1) non-commercially operated aeroplanes with a passenger seating configuration of: (i) up to and including 19 passengers; or (ii) up to and including one half of the maximum passenger seating capacity of the type-certified aeroplane as indicated in the aeroplane type certificate data sheet (TCDS), provided that: (A) the total number of passengers approved for occupancy during taxiing, take-off or landing does not exceed 150 per deck; and (B) the total number of passengers approved for occupancy during taxiing, take-off or landing on a deck does also not exceed one half of the maximum passenger seating capacity for that deck as indicated in the aeroplane TCDS. (2) low-occupancy aeroplanes irrespective of the type of operations (commercial or non-commercial). A low-occupancy aeroplane is defined as an aeroplane which has a passenger seating configuration of: (i) up to and including 19; or (ii) up to and including one third of the maximum passenger seating capacity of the type-certified aeroplane as indicated in the aeroplane TCDS, provided that: (A) the total number of passenger seats approved for occupancy during taxiing, take-off, or landing does not exceed 100 per deck; and (B) the total number of passenger seats approved for occupancy during taxiing, take-off, or landing in any individual zone between pairs of emergency exits (or any dead end zone) does also not exceed one-third of the sum of the passenger seat allowances for the emergency exit pairs bounding that zone, using the passenger seat allowance for each emergency exit pair as defined by the applicable certification basis of the aeroplane. For the purpose of determining compliance with this zonal limitation, in the case of an aeroplane which has deactivated emergency exits, it shall be assumed that all emergency exits are functional. (b) Aeroplane Flight Manual (AFM) Limitation: if compliance with any part of this Appendix limits the aeroplane to non-commercial operations, this limitation must be included in the ‘Limitations’ Section of the AFM.
