If left unfixed, this can cause the handle to disconnect from the door latch, making the door impossible to open from the inside. This creates a serious safety risk if passengers need to evacuate in an emergency.\n\n**Who must comply:**\nOperators of Bell 206B helicopters with serial numbers 3567 through 4577, and 5101 through 5284.\n\n**What must be done:**\n- **Inspect** the inside door handle following the procedures in Bell Helicopter Alert Service Bulletin 206-04-102 (Part I)\n- **If problems are found:** Rework or repair the handle according to Part II of that same bulletin\n\n**When it must be done:**\nBy the next annual inspection after 26 January 2005, but no later than 28 February 2005 (unless already fixed).\n\n**Why it matters:**\nThis prevents a scenario where helicopter occupants could be trapped inside during an emergency because the door handle fails to work."},"flash_summary_failed":{"failed":true,"reason":"Unauthenticated.
