An apparatus and method for preventing damage to overlapping cowl side edges (23, 25) in the event the cowls (3, 4) are closed in the wrong order. The underlapping edge (23) has a cut-out region (22) that is sufficiently large to permit at least a portion (11) of the overlapping edge (23) to pass therethrough if the cowls (3, 4) are closed in the wrong sequence. A flexible, fireproof seal (24) extends across the cut-out region (22), and maintained firewall integrity between the cowls (3, 4). The seal (24) is sufficiently flexible so as to not impede passage of the overlapping edge portion (11) through the cut-out region (22).

On an aircraft engine having at least a pair of hinged cowlings, one positioned forwardly of the other, each of said cowlings being swingable about a hinge axis between an open and closed position, and when both of said cowlings are closed, a trailing side edge portion of said forward cowling overlaps an adjacent leading side edge portion of said aft cowling, thereby enabling said cowlings to cooperatively close a certain region of said aircraft engine, said overlapping trailing side edge portion normally requiring said forward cowling to be opened first but closed second with respect to opening and closing said aft cowling, in order to prevent at least some of said overlapping trailing side edge portion from binding against said leading side edge portion, and consequently damaging one or the other of said trailing and leading side edge portions, a method for preventing such damage in the event said cowlings are closed in the incorrect sequence, comprising: making a cut-out in a certain region of said leading side edge portion of said aft cowling, said cut-out being sufficiently wide and long to permit said at least some of said overlapping trailing side edge portion that would otherwise bind against said leading side edge portion to pass through said cut-out region, in the event it is attempted to close said forward cowling while said aft cowling is open, and attaching a fireproof strip seal to said leading side edge portion of said aft cowling, said seal protruding transversely across said cut-out region, and being sufficiently elastically flexible so as to not interfere with said at least some of said overlapping trailing side edge portion as such portion passes through said cut-out region when said cowlings are closed in the incorrect sequence.
