These are the stickers and signs that tell pilots critical information about fuel tanks, switches, and procedures.\n\n**Why it matters:** The US Federal Aviation Administration (FAA) reviewed the Aerostar fuel system and found the existing placards weren't adequate. Confusing or missing fuel system information can lead to pilots mismanaging fuel — a common cause of engine failure and accidents. This directive makes the fixes mandatory in Australia.\n\n**Who must comply:** Anyone operating these specific Aerostar aircraft models.\n\n**What they must do:** Follow the instructions in **Piper Service Bulletin SB600-79** and install the new placards before **30 June 1979**.\n\n**Key point:** This isn't optional maintenance — it's legally enforceable. Flying without these placards would breach civil aviation law."},"flash_summary":{"complexity_score":2,"scope_assessment":{"changed":false,"description":"The AD implements a specific change (installation of additional and revised fuel-system placards) for the identified aircraft types and sets a compliance deadline.
