These are restraint systems (seatbelts/harnesses) for aircraft occupants.\n\n**Why it matters:**\nThe original cover could jam, trapping passengers or crew in their seats during an emergency. The directive was issued after it was found that occupants might be unable to release their restraint system when they needed to evacuate quickly.\n\n**What had to happen:**\nAircraft operators had six months from 31 August 1983 to complete this replacement.
