The SELA RPU can be identified by a starburst pattern incorporating the text\n\n\\`laboratoire, abadie, France'. The ALC RPU can be identified by a stylised ALC logo with ‘Aerospace Lighting Corp’ in smaller print beneath the logo. The SELA lamp connector is only stamped in yellow ink. The ALC lamp connector has ALC moulded into the body of the conical piece of the connector. The ALC lamp can be positively identified by the presence of a small hole in the locking channel of each blue plastic end piece.\n\nRequirement: Action in accordance with United States Federal Aviation Administration (FAA) AD 90-07-08 Revision 1. Operators of affected aircraft who elect to comply with para a. of the FAA AD, are required to have an Australian Flight Manual amendment specifying the required action. In lieu of inserting a copy of the FAA AD in the Flight Manual, operators intending to take this course of action must prepare and submit a suitable flight manual amendment to their local Civil Aviation Safety Authority (CASA) District Office for approval.\n\nNote 1. If any fluorescent lighting components referred to in the Applicability Statement are found to be installed in any emergency lighting system or any escape path lighting system the correct operation of which is a mandatory certification requirement for that aircraft, then the disabling of such a system in accordance with an FAA AD is NOT permitted.\n\nNote 2.

Laboratoire Abadie — specifically lamp connector P/No 3185-1A and remote power units (RPUs) P/No TR992, TR992A, TR992-1, TR992-3, TR992-4 and TR992-5 — and requires operators to take the corrective actions set out in the United States FAA Airworthiness Directive (FAA AD 90-07-08 Revision 1). (Applicability; Requirement)\n- If an operator chooses the particular option described at paragraph a. of the FAA AD, that choice must be formalised by adding a corresponding amendment to the Australian Flight Manual and getting that amendment approved by their local Civil Aviation Safety Authority (CASA) District Office. (Requirement)\n- The directive explicitly forbids disabling any of these fluorescent components if they are installed as required emergency lighting or escape-path lighting. (Note 1)\n- The amendment took effect on 29 February 1996; the original compliance date referenced the FAA AD (effective 6 October 1990). (Compliance)\n\n**Who this affects:**\n\n- Aircraft operators and owners that have the identified S.E.L.A. components installed (examples listed include Falcon 10/20/50/900, BAe Jetstream 3101/3201, CASA 235, Embraer EMB-120, SAAB-Scania SF340A). (Applicability; Note 1)\n- Maintenance organisations and engineers who inspect and replace lighting components and who must update Flight Manuals when required. (Requirement; Note 3)\n- CASA, which reviews and approves any Flight Manual amendments submitted under this directive. (Requirement)\n\n**Why it matters (official rationale plus practical implications):**\n\n- The directive follows reports of smoke and fire linked to arcing or overheating of the lamp connector or RPU (Background). The stated purpose is to prevent smoke, fire, electric shock or electromagnetic interference with flight‑critical or essential systems. (Background)\n- Practically, affected operators will need to inspect aircraft for the listed parts, follow the FAA AD's corrective actions (which typically include repair, replacement or modification), and, if they use the FAA AD option that leaves an operational restriction in place, record that restriction in the Flight Manual and obtain CASA approval. (Requirement)\n\n**Costs, incentives and likely behaviour changes:**\n\n- Who pays: operators pay inspection and maintenance costs (labour, parts, possible aircraft downtime) and any administrative cost to prepare and submit Flight Manual amendments. (Requirement; Compliance)\n- Who decides: operators choose which FAA-AD-prescribed corrective option to follow; CASA decides whether to approve a Flight Manual amendment. (Requirement)\n- Behaviour change: aircraft operators will increase inspection and/or replacement activity for the specific S.E.L.A. parts and may change sourcing of replacement components. If operators choose an FAA-AD option that restricts use of the lights, they must document that in the Flight Manual and obtain CASA approval. (Requirement; Note 1)\n\n**Trade-offs, risks and implementation considerations:**\n\n- Trade-offs: immediate safety mitigation (reduced fire/arc risk) versus up-front maintenance/administrative costs and potential operational disruption while work is done. (Background; Requirement)\n- Substitution effects: operators may replace SELA parts with alternative suppliers' parts or alternative lighting technology, affecting demand for suppliers. (Applicability; Note 2)\n- Compliance burden: requires coordination with CASA for Flight Manual amendments if the operator elects certain compliance options, and reliance on an external FAA AD for the technical corrective actions (cross‑jurisdictional reference). (Requirement)\n- Implementation risk: effectiveness depends on accurate identification of parts (detailed identification notes are included) and on operators following the FAA AD instructions. If components are used in mandatory emergency systems, the directive prohibits disabling them, which limits some compliance options and raises complexity for retrofits. (Notes 1–3)\n\n**Concentrated benefits and diffuse costs:**\n\n- Benefits from reduced fire/electrical risk accrue to passengers, crew and specific aircraft operators (safety gain concentrated on users of affected aircraft). Costs (maintenance, replacement parts, paperwork) are borne by operators; the cost per operator is concentrated but the affected population is relatively small. (Applicability; Background)\n\n**Sources of technical information and points of contact:**\n\n- The directive points operators to the FAA AD text and to the aircraft and component manufacturers' maintenance manuals, SELA technical data, and Bigorre Aerospace documentation for technical instructions and identification guidance. Contact details and locations to view documents are supplied. (Requirement; Note 3)\n\n**Net effect in plain terms:**\n\n- This document forces operators who have the specified SELA cabin fluorescent components to follow the FAA's corrective steps, to document certain choices in the Flight Manual with CASA approval if applicable, and to avoid disabling those components where they form part of mandatory emergency lighting. The outcome is intended to reduce fire and electrical risks at the cost of inspections, repairs or replacements, and some administrative work.
