Specifically, it's about certain parachute models made by GQ.\n\n**Who it affects:** Anyone who owns or operates these specific GQ parachute models: Types 350, 850, and 4.8m SAC. The directive lists eight specific part numbers that are covered.\n\n**What you must do:** If you have one of these parachutes, you need to:\n- **Remove or cover up** the \"TSO-C23b\" marking on the parachute canopy (this is a technical certification marking)\n- **Take the parachute out of service immediately** — meaning don't use it\n\n**Why this matters:** The parachute canopy mesh panels have been found to be **acidic**, which is damaging the strength of the fabric around them. This means the parachute might not work properly in an emergency — a serious safety risk.\n\n**When to act:** \"Forthwith\" means **immediately** — don't wait.\n\n**Background note:** This follows a similar US safety notice (FAA AD 89-13-03), suggesting this is a known international issue with these parachutes."}},"importantCases":[],"_links":{"self":"/api/acts/ad-para-2-gq-types-350-850-and-4-8m-sac-parachutes","history":"/api/acts/ad-para-2-gq-types-350-850-and-4-8m-sac-parachutes/history","analysis":"/api/acts/ad-para-2-gq-types-350-850-and-4-8m-sac-parachutes/analysis","conflicts":"/api/acts/ad-para-2-gq-types-350-850-and-4-8m-sac-parachutes/conflicts","importantCases":"/api/acts/ad-para-2-gq-types-350-850-and-4-8m-sac-parachutes/important-cases","documents":"/api/acts/ad-para-2-gq-types-350-850-and-4-8m-sac-parachutes/documents"}}
