The invention relates to a method of providing a seal between an aircraft structure
(14) and a removable panel (26) mountable on the structure to close
an opening (12) therein. According to the invention, the method comprises
applying a sealant compound (28) for example a polysulphide rubber compound,
to one of the structure and the panel, forming a rebate (46) in the sealant
compound, and providing a sealant tape (48) to fit within the rebate. Subsequently,
the panel is fastened to the structure with the seal (50) comprising the
sealant compound and the sealant tape being sandwiched between the structure and
