You must do one of three things (see \"Requirement\"):\n  - Reconnect the lighter circuit to the electrical bus but only with a correctly rated circuit protection device (i.e. a circuit breaker or fuse sized for the wire gauge); or\n  - Remove the wire entirely by disconnecting it at the lighter receptacle end and taking it out of the aeroplane; or\n  - Leave the wire disconnected, insulate the cut end, fold it back into the wire bundle and secure it so it cannot chafe or contact other parts.\n\n- The AD cross-references FAA AD 79-08-03 and an FAA advisory circular (AC 43.13-1B Chapter 11) for how to choose the correct circuit protection device and for prior-compliance recognition.\n\n- Compliance deadline: do the required action at the next annual inspection but no later than 100 hours time-in-service or 12 months after the AD’s effective date, whichever comes first.\n\n**Who this affects**\n\n- Owners and operators of the specified Cessna 188 serial-numbered aeroplanes.  \n- Maintenance organisations and certificated mechanics who perform annual inspections or corrective electrical work on those aircraft.  \n\n**Why it matters (stated purpose and practical effect)**\n\n- The AD is issued to correct an unsafe condition associated with the cigar lighter wiring (the AD cites background reasons). In practical terms, it stops a potentially unprotected or incorrectly protected cigar-lighter circuit from remaining connected to the aircraft electrical system. That reduces the risk that a short, overload or chafing on that wire could cause electrical damage or a fire.\n\n**Costs, incentives and trade-offs (practical testing of the stated purpose)**\n\n- Who pays: aircraft owners/operators bear the cost (labour and any parts).\n- Typical cost drivers: mechanic labour at the annual inspection; if the owner selects reconnection with a new circuit protection device, there is a parts cost and installation labour. Removing the wire or insulating and stowing it will generally be cheaper than installing protective hardware.\n- Incentives: owners can choose the cheapest compliant option (insulate and stow, or remove), which lowers immediate cost but leaves the cigar lighter unusable. Choosing reconnection with proper circuit protection preserves functionality but costs more. The AD therefore creates a direct trade-off between preserving an onboard convenience and paying for correct electrical protection.\n- Implementation risk and compliance burden: low. The required actions are routine electrical maintenance tasks within the skill set of certificated aircraft electricians/maintenance organisations. The AD gives three concrete options rather than a detailed mandated method, reducing prescriptive compliance complexity. The AD relies on an FAA advisory circular for sizing the protective device rather than reproducing technical detail.\n- Effect on private enterprise: small and concentrated. Independent maintenance shops and parts suppliers may get additional work from owners choosing reconnection. Competitive behaviour among maintenance providers can limit price impacts. There is no broad effect on competition, ownership or operation beyond the maintenance cost and possible loss of lighter functionality if owners choose removal.\n- Substitution effects: owners who want to avoid the expense may remove or disable the lighter; others will pay to install correct protection.\n\n**Where to look in the AD for specifics**\n\n- Applicability: the serial-number range of affected aircraft (see \"Applicability\").  \n- Requirement: the three alternative corrective actions (see \"Requirement\").  \n- Compliance: timing for when the work must be done (see \"Compliance\").  \n- Notes: references to FAA AD 79-08-03 and FAA AC 43.13-1B Chapter 11 for prior compliance recognition and guidance on circuit protection sizing (see \"Note 1–3\").\n\nOverall, the AD is a narrowly targeted safety directive that requires a simple electrical fix or removal/insulation of a cigar-lighter circuit on specified Cessna 188 aircraft, with modest compliance cost and routine implementation by maintenance organisations."}},"importantCases":[],"_links":{"self":"/api/acts/ad-cessna-188-45-cigar-lighter-wiring","history":"/api/acts/ad-cessna-188-45-cigar-lighter-wiring/history","analysis":"/api/acts/ad-cessna-188-45-cigar-lighter-wiring/analysis","conflicts":"/api/acts/ad-cessna-188-45-cigar-lighter-wiring/conflicts","importantCases":"/api/acts/ad-cessna-188-45-cigar-lighter-wiring/important-cases","documents":"/api/acts/ad-cessna-188-45-cigar-lighter-wiring/documents"}}
