The Civil Aviation Safety Authority (CASA) has updated an existing safety rule that applies to all British Aerospace Jetstream 3100 and 3200 aircraft.\n\n**What happened:** A wiper arm fell off a plane in mid-flight, damaging the propeller and fuselage. The original safety rule required airlines to replace wiper arms and bolts, and then replace them again after a set period of use.\n\n**What's changed:** This update (Amendment 1) adopts the latest manufacturer instructions (BAE Systems Mandatory Service Bulletin 30-JA 950641 Revision 5). The key change is adding a **\"terminating action\"** for Part 1 — this means there's now a permanent fix that ends the need for repeated replacements.\n\n**Who must act:** Owners and operators of all Jetstream Series 3100 and 3200 aircraft.\n\n**When:** The new rule takes effect on 7 August 2003. Compliance timing follows the manufacturer's bulletin."}},"importantCases":[],"_links":{"self":"/api/acts/ad-jetstream-76-amdt-1-windshield-wipers","history":"/api/acts/ad-jetstream-76-amdt-1-windshield-wipers/history","analysis":"/api/acts/ad-jetstream-76-amdt-1-windshield-wipers/analysis","conflicts":"/api/acts/ad-jetstream-76-amdt-1-windshield-wipers/conflicts","importantCases":"/api/acts/ad-jetstream-76-amdt-1-windshield-wipers/important-cases","documents":"/api/acts/ad-jetstream-76-amdt-1-windshield-wipers/documents"}}
