The incorrect 28-volt lamps look identical to the correct ones but will **stop the smoke detector from working** — meaning a fire in the cargo hold might not be detected.\n\n**What must be done:**\n- Operators must follow the manufacturer's service bulletin (repair instructions) dated 14 April 1986.\n- They can use locally made labels/decals instead of original ones, as long as the information matches.\n- The fix must be completed **within 30 days after 31 July 1986**.\n\n**Who it affects:**\n- Airlines and operators flying Boeing 767s with these specific Autronics smoke detectors installed.\n\n**Why it matters:**\n- Faulty smoke detectors in cargo compartments create a serious fire risk.
