Applicability: All model 125 series 800A and 800B aeroplanes.

Requirement: Unless previously accomplished, incorporate “smoke drill indicator labels” in accordance with British Aerospace Service Bulletin SB.24-288-3284A dated 7 February 1992.

Compliance: The compliance remains unchanged as “As specified in the Requirements Document with a revised effective date of 31 July 1992”.
