It allows this aircraft to operate with flight recording equipment that doesn't fully meet the usual standards.\n\n**What it does:**\n- **Revokes a previous approval** (CASA 51/98) that presumably had different conditions\n- **Grants special permission** for aircraft VH-LHH to use:\n  - A flight data recorder that keeps the last 8 hours of flight data (the \"black box\" that records technical information)\n  - A cockpit voice recorder that keeps the last 60 minutes of audio, but with a catch — it only records on 3 channels instead of the usual requirement\n\n**Who it affects:**\n- The operator/owner of aircraft VH-LHH\n- CASA inspectors who monitor compliance\n\n**Why it matters:**\nFlight recorders are crucial for accident investigation. Normally, CASA requires voice recorders to capture more channels (typically 4) to ensure all cockpit conversations and sounds are captured. This approval gives VH-LHH an exemption — it can operate legally with a slightly less capable recorder, provided it meets specific maintenance and operational rules (referenced as sections 6.3, 6.4 and 6.6 of Civil Aviation Orders section 20.18).\n\nThis is a routine administrative instrument granting a technical exemption for one specific aircraft."},"flash_summary":{"complexity_score":3,"scope_assessment":{"changed":true,"description":"This instrument revokes the earlier instrument CASA 51/98 (clause (a)) and replaces it with a new approval under subregulation 207(2) that authorises operation of the specific aircraft VH‑LHH subject to defined recorder retention periods (8 hours for the FDR; 60 minutes for the CVR) and a permitted deviation from the recording-channel requirement (CVR recording simultaneously on only 3 channels) (clauses (b)(i)–(ii)).
