Brightwork Polish at Lyon-Saint-Exupéry (LFLL)

What does brightwork polishing involve at Lyon-Saint-Exupéry?

We arrive airside with hand-polishing compounds, microfibre bonnets, rotary tools and sealant. The aircraft remains on stand; no hangar is required. Leading edges on wings and horizontal stabilisers are polished first—these surfaces see the highest airflow and oxidise fastest. Engine inlet rings and spinners follow, then exhaust cones and thrust-reverser petals if the nacelle design exposes bare metal. Window surrounds, cheat-line trim and any other brightwork are addressed last.

After polishing, we apply a thin sealant layer to the metal. The coating bonds to the aluminium and slows the oxidation cycle, so the mirror finish lasts longer between services. The sealant cures within an hour; the aircraft can depart as soon as the tech log is signed. We work around GPU connections, pitot covers and static ports without disturbance, and all avionics bays and sensor windows are treated as no-touch zones.

What changes at Lyon-Saint-Exupéry in terms of operations and access?

Lyon-Saint-Exupéry sits at 821 feet elevation, twenty kilometres east of the city centre. The airport operates around the clock, but a COHOR schedule-facilitation window applies to all IFR traffic between 06:00 and 22:59 local time. Business-aviation handling is available twenty-four hours a day, which means overnight polishing work can be arranged if the aircraft will remain on stand through the small hours.

Two parallel runways—four thousand metres and 2,670 metres—serve the field, and Aéroports de Lyon (part of the VINCI consortium) manages the site. The same operator runs Lyon-Bron, a dedicated business-aviation airport where hangars and long-term storage are concentrated; Saint-Exupéry is primarily a turnaround field for business jets, so most detailing here is scheduled around a single overnight or a brief maintenance stop rather than extended downtime.

We coordinate airside access through the handling agent present at the airport. An escort is arranged if our team does not hold a permanent pass for the apron. The handler will confirm stand availability and any movement restrictions; we adapt our schedule to fit your slot and the handler's ground-operations rhythm.

How does Lyon's climate affect bare-metal surfaces?

Lyon sits in a temperate zone with warm summers and cool, damp winters. Rain is distributed fairly evenly across the year, and the Rhône valley funnels wind through the region, which accelerates the drying cycle on the ramp but also deposits industrial particulate and road dust on parked aircraft. Bare aluminium oxidises faster in moist air; even a week on stand will dull leading edges and inlet rings if they have not been sealed recently.

Winter brings occasional freezing fog and the need for Type I or Type IV fluid. De-icing chemicals are mildly corrosive and will stain brightwork if left to dry on the surface. A quick rinseless wash after a de-iced departure, followed by a full polish during the next scheduled stop, keeps the metal clean. In summer, high apron temperatures soften any residual sealant, so we time the work for early morning or late evening when the metal has cooled and the compound adheres properly.

Should brightwork polishing be scheduled as recurring maintenance or a one-off detail?

Recurring schedules—two to four times a year—are the most practical approach for fleet operators and charter programmes. Leading edges lose their lustre within three to six months of normal flight operations, faster if the aircraft frequently operates into coastal or industrial environments. A standing calendar appointment means the metal is always presentation-ready, and each session takes less time because oxidation never becomes heavy.

One-off polishing makes sense when an aircraft has just come out of paint, when brightwork has been neglected for a year or more, or before a sale or charter showcase. The first session on a heavily oxidised surface will take longer—sometimes a full three days—because we work through coarser compounds before moving to the final mirror stage. After that initial correction, maintenance polishing every quarter keeps the finish stable with minimal effort.

We also offer Brightwork Polish as one component of a Complete Detail. If the fuselage is being hand-waxed and the cabin deep-cleaned, adding brightwork to the scope adds only half a day to the overall timeline and ensures every visible surface matches the same standard.

What do handlers at Lyon-Saint-Exupéry expect from a third-party detailing crew?

Handling agents expect clear communication about stand occupancy, power requirements and waste disposal. We confirm the work window—start time, estimated finish, any breaks for towing or refuelling—before the aircraft arrives or as soon as it blocks in. If the job spans more than one day, the handler needs to know whether the stand will be occupied overnight or if the aircraft will be repositioned to another part of the apron.

We bring our own equipment, water (when a rinseless wash precedes polishing) and waste containers. Polishing compound residue and used microfibre cloths are bagged and removed; nothing is left on the ramp. If GPU power is needed for cabin lighting during evening work, we coordinate that through the handler. Some agents prefer to supply the ground power themselves; others are happy for us to connect directly if we hold the appropriate airside authorisation.

Insurance and safety documentation are shared in advance. Handlers want to see public liability cover, proof of aviation-specific training and a method statement if the work involves ladders or access platforms near control surfaces. Meeting these expectations on the first visit builds trust and makes subsequent turnarounds faster.

How long does brightwork polishing take, and can it fit inside a turnaround?

A typical super-midsize or large-cabin jet with moderate brightwork—wing and stabiliser leading edges, two inlet rings, exhaust petals and window surrounds—requires one full day if the metal is in reasonable condition. If oxidation is heavy or the aircraft has extensive bare-metal trim, the work stretches to two or occasionally three days. We give a firm timeline once we have seen the aircraft or reviewed recent photographs.

Fitting the service into a short turnaround is possible if the aircraft will remain on stand for at least twelve hours and the brightwork is limited. An overnight arrival with a mid-morning departure the next day gives us enough time to polish leading edges and inlets, provided the handler can guarantee the stand will not be needed for another movement. For anything more comprehensive, plan on the aircraft being stationary for a full twenty-four-hour cycle or longer.
