1. A transparency quick seal system for sealing between a substantially rigid transparency having an outer surface and an inner surface and an aircraft frame including a fairing extending between the aircraft frame and the outer surface of the transparency to receive the edge of the transparency in a well defined therebetween, the combination comprising:

  • fastener means extending through said transparency and said frame for securing said transparency to said frame;

    a first pressure seal secured by said fastener means sandwiched between the aircraft frame and the inner surface of the transparency;

    said first pressure seal having a substantially L-shaped cross-section including a relatively thin first portion and a contiguously located relatively thicker second portion to increase the seal effect between the inner surface of the transparency and said aircraft frame and including a plurality of apertures at said contiguous location extending partially through each of said first and second portions and through which to receive said fastener means;

    a second pressure seal separate and independent of said first pressure seal and comprising an elongated strip of dry silicone elastomeric material attached to a distal edge of the fairing and abutting against the outer surface of the transparency for sealing between the transparency and the fairing;

    said second pressure seal being of an integral composition having an inner surface abutting the outer surface of the transparency and an outer surface having a bifurcated extension extending in a substantially lateral relation from said outer surface so as to define a pair of flexible extensions with an intervening longitudinal slot opening into which the distal edge portion of the fairing is received, the longitudinal slot being formed with internal surface contours substantially conforming with the opposite surface contours of the received distal edge portion of the received fairing for oppositely engaging the surfaces of the received fairing to effect a form fit continuous seal therebetween; and

    a quantity of adhesive disposed on said internal surface contours for attaching said second seal to the received distal edge portion of the fairing.
