I guess you are looking for CAT to/from rigs. However I only found this:
SPO.IDE.H.195 Flight over water — other-than-complex motor-powered helicopters- (a) Helicopters shall be equipped with a life-jacket for each person on board, that shall be worn or stowed in a position that is readily accessible from the seat or station of the person for whose use it is provided, when:
(1) flying over water beyond autorotational distance from the land where in case of the critical engine failure, the helicopter is not able to sustain level flight; or
(2) flying over water at a distance of land corresponding to more than 10 minutes flying at normal cruising speed, where in case of the critical engine failure, the helicopter is able to sustain level flight; or
(3) taking off or landing at an aerodrome/operating site where the take-off or approach path is over water.
- (b) Each life-jacket shall be equipped with a means of electric illumination for the purpose of facilitating the location of persons.
- (c) The pilot-in-command of a helicopter operated on a flight over water at a distance from land corresponding to more than 30 minutes flying time at normal cruising speed or 50 NM, whichever is less, shall determine the risks to survival of the occupants of the helicopter in the event of a ditching, based on which he/she shall determine the carriage of:
(1) equipment for making the distress signals;
(2) life-rafts in sufficient numbers to carry all persons on board, stowed so as to facilitate their ready use in emergency; and
(3) life-saving equipment to provide the means of sustaining life, as appropriate to the flight to be undertaken.
- (d) The pilot-in-command shall determine the risks to survival of the occupants of the helicopter in the event of a ditching, when deciding if the life-jackets required in (a) shall be worn by all occupants.
SPO.IDE.H.203 All helicopters on flights over water — ditching
Complex motor-powered helicopters operated on a flight over water in a hostile environment at a distance from land corresponding to more than 10 minutes flying time at normal cruising speed and other-than-complex motor-powered helicopters flying over water in a hostile environment beyond a distance of 50 NM from land shall be:
- (a) designed for landing on water in accordance with the relevant airworthiness code;
- (b) certified for ditching in accordance with the relevant airworthiness code; or
- (c) fitted with emergency flotation equipment.
It seems it is distinguished between complex motor-powered aircraft and other-than complex motor-powered aircraft only and then referred to whether a helicopter is able to sustain level flight in case of critical engine failure (not even at what stage of flight), doesn't it?
Complex motor-powered aircraft are defined in Article 3 of Regulation (EC) No 216/2008:
‘complex motor-powered aircraft’ shall mean:
(i) an aeroplane:
with a maximum certificated take-off mass exceeding 5 700 kg, or
certificated for a maximum passenger seating configuration of more than nineteen, or
certificated for operation with a minimum crew of at least two pilots, or
equipped with (a) turbojet engine(s) or more than one turboprop engine, or
(ii) a helicopter certificated:
for a maximum take-off mass exceeding 3 175 kg, or
for a maximum passenger seating configuration of more than nine, or
for operation with a minimum crew of at least two pilots,
or
(iii) a tilt rotor aircraft.
And maybe it is worth looking at this piece:
