Specifically, they must ensure the flight display symbols on the main electronic attitude display match those on the backup (standby) attitude indicator.\n\n**Who it affects:**\nOnly 13 specific aircraft — TBM 700 series planes with serial numbers 14, 19, 21, 24, 25, 27, 49, 50, 53, 62, 74, 84 and 85.\n\n**Why it matters:**\nHaving consistent symbols between the main flight display and the backup prevents pilot confusion during emergencies. If the main system fails and the pilot switches to the backup, the instruments should look and behave identically to avoid misreading critical flight information.\n\n**What must be done:**\nOperators must follow the manufacturer's mandatory service bulletin (SB 70-030-34) issued in March 1994, and complete the work within 100 flight hours after 8 December 1994.\n\n**Key terms explained:**\n- **Airworthiness Directive (AD):** A legally enforceable safety notice requiring aircraft modifications or inspections\n- **EFIS:** Electronic Flight Instrument System — the digital screens that replace traditional 'steam gauge' flight instruments\n- **EADI:** Electronic Attitude Director Indicator — the screen showing the aircraft's pitch and bank (whether it's climbing, descending, or turning)\n- **Time in service:** Actual flight hours, not calendar time"}},"importantCases":[],"_links":{"self":"/api/acts/ad-tbm-700-7-efis-configuration","history":"/api/acts/ad-tbm-700-7-efis-configuration/history","analysis":"/api/acts/ad-tbm-700-7-efis-configuration/analysis","conflicts":"/api/acts/ad-tbm-700-7-efis-configuration/conflicts","importantCases":"/api/acts/ad-tbm-700-7-efis-configuration/important-cases","documents":"/api/acts/ad-tbm-700-7-efis-configuration/documents"}}
