This involves inspecting and likely replacing certain bolts to ensure the landing gear doesn't fail.\n\n**When you must comply:** Within 100 hours of flight time after 30 September 1982.\n\n**Why it matters:** The manufacturer identified a safety issue with the strength of the bolts holding the nose wheel assembly.
