The Civil Aviation Safety Authority (CASA) is requiring owners or operators of certain TBM 700 series aeroplanes to fix a problem with their emergency oxygen systems.\n\n**What the problem is:**\nThe oxygen generators (emergency devices that produce oxygen for passengers if cabin pressure is lost) have a faulty \"striker pin\" — a small part that triggers the oxygen flow. If this pin fails, the oxygen won't flow when needed.\n\n**Who must act:**\nAnyone who owns or operates a TBM 700 series aircraft with serial number 1 or higher, **unless** the aircraft has already been modified with \"Socata modification No 70-099-35\".\n\n**What must be done:**\nReplace the striker pin and add a washer to each oxygen generator, following the manufacturer's instructions in \"Service Bulletin 70-046-35\" dated May 1998.\n\n**When it must be done:**\nBy the next regular maintenance check, but absolutely no later than 11 September 1998.\n\n**Why it matters:**\nThis prevents a situation where passengers and crew might need emergency oxygen but not get it due to a mechanical failure.
