The Required action (see \"Requirement\") is one of three options, if it has not already been done:\n  - reconnect the cigar‑lighter feed to the aircraft electrical bus but only using a circuit protection device (fuse or circuit breaker) correctly rated for the wire gauge used, or\n  - disconnect the feed at the lighter receptacle and remove that wire from the aeroplane, or\n  - disconnect the feed, insulate the disconnected end, fold it back into the wiring bundle and secure it there.\n- The AD cross‑references an FAA Airworthiness Directive (FAA AD 79‑08‑03) and notes that aircraft already modified per that FAA AD comply. It also points to FAA Advisory Circular 43.13‑1B Chapter 11 for guidance on selecting the correct protection device. (See \"Note 1\" and \"Note 2\".)\n- Compliance timing (see \"Compliance\"): carry out the required action at the next annual inspection, or no later than 100 hours time in service, or within 12 months of the AD’s effective date — whichever of those occurs first.\n\n**Who is affected**\n\n- Owners/operators of the specified Cessna 190 and 195 aircraft (serial number ranges above).\n- Licensed maintenance organisations/engineers who perform annual inspections and electrical work on those aircraft.\n\n**Why it matters (stated purpose, and practical effect)**\n\n- The AD’s stated purpose is to correct an unsafe condition arising from the cigar‑lighter wiring (see background statement). Mechanically, the AD eliminates an unprotected or improperly protected electrical feed to a cigar lighter receptacle that could overheat, short or otherwise create an electrical/fire risk.\n\n**Who pays, who decides, and what changes in behaviour**\n\n- Aircraft owners/operators pay: labour at the annual inspection and any parts (a circuit breaker or wiring work) if they choose the reconnection option.\n- The CASA delegate issues the AD; the aircraft owner/operator (or their maintenance provider) decides which of the three compliant options to implement.\n- Behaviour change required: either fit properly protected circuitry, remove the unused feed, or secure and insulate the disconnected feed so the lighter circuit cannot energise or short.\n\n**Trade‑offs, costs and implementation considerations**\n\n- Direct costs: modest maintenance labour; possible parts cost if installing a properly rated circuit protection device (breaker/fuse). If the lighter feed is removed/insulated, the aircraft loses that outlet’s functionality.\n- Compliance burden: work is scheduled to coincide with the next annual inspection (or earlier if 100 flight hours/12 months is reached), reducing the need for an extra maintenance visit but concentrating cost at the inspection event.\n- Technical risk: if an owner reconnects the feed but fits undersized or incorrectly installed protection, the safety issue could remain — the AD directs use of appropriate protection (and points to FAA AC 43.13‑1B Chapter 11 for sizing guidance) (Requirement; Note 2).\n- Administrative/interaction costs: compliance may require consultation of FAA guidance or prior AD compliance records (Note 1 refers to FAA AD 79‑08‑03).\n- Market effects: negligible on competition or prices in aviation markets; small demand for replacement circuit protection devices and minor maintenance services concentrated among the affected serial‑number cohort.\n\n**Implementation risk and unintended consequences**\n\n- If owners choose the low‑cost option of insulating and stowing the wire, the immediate safety hazard is mitigated but functionality is lost; if owners later reinstall accessories, there is a risk of reintroducing the unsafe condition unless the wiring is properly protected.\n- The AD gives three compliance paths, which reduces bureaucratic discretion in enforcement but places technical judgement on maintenance personnel to select and install proper protection when the reconnection option is chosen.\n\n**Net practical summary**\n\n- The AD mandates a straightforward electrical safety correction for a defined subset of Cessna 190/195 aircraft. It leaves owners a choice of three remedial actions that trade off cost, functionality and permanence, and it relies on maintenance personnel to implement the chosen option correctly (Requirement; Compliance; Notes)."},"kimi_summary":{"content_quality":"ok","complexity_score":2,"scope_assessment":{"changed":false,"description":"This AD maintains its original narrow scope — addressing a specific wiring safety defect in specific Cessna aircraft models.
