The CAA is required by law to maintain the Registers of Births, Deaths and Missing Persons on UK Registered Aircraft. Unlike the UK Register of Civil Aircraft please note that these registers are not in the public domain. There are various regulations relating to the procedure to be followed if a birth or death occurs on a UK Registered aircraft. Similar provisions exist if a person goes missing following an accident on a UK Registered aircraft. To view a guide to the legislative requirements see CAA Doc 208.
