It requires owners and operators of specific Piper PA-34 Seneca aircraft to replace a fuel quantity placard (a label or sign showing fuel levels).\n\n**Who it affects:**\n- Owners and operators of **Piper PA-34-200** aircraft with serial numbers 34-7250001 to 34-7450220\n- Owners and operators of **Piper PA-34-200T** aircraft with serial numbers 34-7570001 to 34-7570308\n\n**What must be done:**\n- Replace the existing fuel quantity placard following the instructions in **Piper Service Bulletin No. 438**\n- Complete this work **within 100 hours of flight time** after 28 November 1975\n\n**Why it matters:**\nFuel quantity placards are critical safety equipment. Incorrect fuel readings or unclear placards can lead to fuel mismanagement, potentially causing engine failure or accidents. This directive ensures pilots have accurate, clearly visible fuel information.\n\nThis AD was originally issued in **November 1975** (hence the \"11/75\" reference) and remains part of Australia's ongoing aircraft safety requirements."},"flash_summary":{"complexity_score":2,"scope_assessment":{"changed":false,"description":"The provided text presents the AD as issued with a narrow, explicit scope: it applies to the listed PA‑34 models and serial‑number ranges, requires replacement per Piper SB No. 438, and sets a specific compliance timeframe.
