Dear Ana, as far as I know, the applicable regulation for safety cards is CAT.OP.MPA.170 (commercial ops) and there is no specific requirement to have the complete EEL, as long as the requirements of passenger briefing from the regulation are covered.

Considering CAT operators, for the crew, per AMC3 ORO.MLR.100 (a) B 10 Survival and Emergency Equipment including Oxygen, the OM-B must include: "10.1 - A list of the survival equipment to be carried for the routes to be flown and the procedures for checking the serviceability of this equipment prior to take-off. Instructions regarding the location, accessibility and use of survival and emergency equipment and its associated checklist(s) should also be included."
For passengers as Javier mentioned the requirements per CAT.OP.MPA.170 apply. GM2 CAT.OP.MPA.170 explicitly mentiones some aspects that should be covered, including the location of flotation devices, oxygen system, escape routes, available evacuation equipment and emergency exits, etc. This information should be expanded for operators conducting operations without cabin crew.
The German CA provides some good guidance:

Dear Ana,

From my experience the answer is yes. It has to on board and in a visible place. In case of emergency, the cabin crew / passenger shall have the access to the EEL. This document shall be reviewed on a regular basis to ensure that it reflects the reality (i.e., Registration marks, location of emergency equipment, quantities, etc.).

I confess that I felt some difficulty on addressing this specific item. Nevertheless, the requisite ORO.AOC.135(b)(2), for example, can be object of assessment during a Ramp Inspection, while the inspector asks a crew member were is located the DAE or where are located the seat belts extensions. In this case the crew member should refer to one of the EEL (typically located on the a/c galleys).

As mentioned above, I could not find a specific requisite. Maybe other member can give an help on this.

Regards

Dear Ana, the answer is „no“. However, as João mentioned above SAFA inspectors ask regularly for it, in order to ensure the appropriate equipment is on board prior each flight together with the required checks completed. Ensure that you know where it is located in your on-board library quickly, when required. I found no such rule in Roberts LBA 24 pages reference above. Best wishes & happy landings.

Dear Ana,
Refer to AIR OPS Easy Access Rules_Rev.12_March Annex III-Part-ORO Page 108 says:
10.1 A list of the survival equipment to be carried for the routes to be flown and the procedures for checking the serviceability of this equipment prior to take-off. Instructions regarding the location, accessibility and use of survival and emergency equipment and its associated checklist(s) should also be included.
Hope this address help you find the correct answer.

In the event the physical card cannot be found, can it be digital on the EFK from the crew?
