When the pilot pulls the control wheel fully back (elevator full up position), the glove box might touch or jam these flight controls — a serious safety risk.\n\n**What must be done:**\n- **Immediate inspection:** Check that there's enough clearance between the glove box and the control chain. This can be done by the pilot themselves and recorded in the aircraft's maintenance records.\n- **Permanent fix within 5 flying hours:** Either brace (reinforce) the glove box mounting so it can't move and interfere with controls, or remove the glove box entirely.\n\n**Who it affects:**\nAnyone who owns, operates, or maintains a Cessna 150G or 150H aircraft registered in Australia.\n\n**Why it matters:**\nFlight control interference can cause loss of control of the aircraft. This directive prevents accidents by ensuring the glove box cannot foul (jam or obstruct) critical flight controls."},"flash_summary":{"complexity_score":2,"scope_assessment":{"changed":true,"description":"The heading refers broadly to Cessna 150, F150, 152 & F152 series aeroplanes, but the formal applicability line limits the directive to all model 150G and 150H.
