Reference: CS-25 (Large Aeroplanes)
Baby bassinets are currently included in a certification process of the particular aircraft in which they will be installed; baby bassinets are not certified as a separate device and they are not certified for taxi, take-off, landing and turbulent weather conditions. Placards advising on their stowage during taxi, take-off, landing and turbulence are required either at the location where baby bassinets will be fixed to the aircraft structure (e.g. bulkhead) or a clearly visible instruction advising on the same must be in place on the baby bassinet itself.
Because of the standard fixation of the unit, they are not stable during turbulence, they may swing up and down, and therefore they must be stowed during turbulence.
The placarding requirements are related to the general certification requirements on placarding and intended function in accordance with Certifications Specifications and Acceptable Means of Compliance for Large Aeroplanes CS-25 (ED Decision 2012/008/R) and the marking requirements as specified in the approval of the equipment. The applicable reference paragraph is CS 25.1301, 25.1541. There is no specific mention of baby bassinets, however, equipment installed in an aircraft must meet the applicable requirements of the certification basis, the equipment specifications (if available) or aircraft manufacturer specifications (if available), or NAA requirements applicable to the operation of the aircraft.
For any questions on certification matters, do not hesitate to contact EASA Certification directorate.
