Brightwork Polish at Avignon Provence (LFMV)

Why polish brightwork at Avignon Provence?

Bare aluminium oxidises quickly in sunlight, and the Rhône valley's dry summer air accelerates the process. Dull leading edges and grey inlet rings are the first things a passenger notices on the apron; restoring them to a mirror finish lifts the appearance of the entire aircraft. Polishing also removes embedded contaminants—exhaust residue on thrust-reverser cowls, hydraulic mist on nacelle lips—that ordinary washing cannot shift.

The work is entirely by hand: we mask surrounding paint, then step through progressively finer compounds until the metal reflects like glass. After the final pass we apply a polymer sealant that fills the microscopic surface texture and slows the return of oxidation. The sealant typically holds four to six months, depending on utilisation and where the aircraft spends its nights. Window surrounds and polished cheat-line trim receive the same treatment if the airframe design includes them.

Avignon's compact apron and absence of slot coordination mean we can start as soon as the GPU is plugged in. There is no queue for a remote stand, no tug delay, no pressure to vacate for the next arrival. That predictability matters when the calendar calls for a two-day polish between owner trips.

What changes at Avignon Provence?

The airport sits at 124 feet elevation with a single paved runway—17/35, roughly 1,880 metres—and positions itself as totally adapted to business aviation. The dedicated terminal, opened in March 2009, is a 120-square-metre reception building with an executive lounge; one handling agent operates the facility and coordinates all apron movements. Because the airport is not slot-coordinated and customs clearance is available on request, arrival and departure windows flex around the detail schedule rather than the other way round.

The short runway steers most intercontinental jets to Marseille or Nice, but super-midsize and large-cabin aircraft land comfortably, and the single handler knows every third-party crew by name after the first visit. Airside escort requirements are straightforward: the handler issues a pass, walks us to the stand for the initial survey, then leaves us to work. If the aircraft is cold-soaked from an early-morning positioning flight, we wait for the wing skin to reach ambient temperature before opening compound tins; polishing cold metal traps moisture under the sealant and shortens its life.

Avignon's Mediterranean climate means summer apron temperatures regularly touch thirty-five degrees. We start leading-edge work at first light, break during the afternoon peak, then resume in the evening if the schedule allows. Winter days are mild enough for uninterrupted polishing, though the mistral occasionally forces us to tent the inlet area to keep dust out of the compound.

What does a brightwork-polish turnaround look like on the Avignon ramp?

The handler parks the aircraft on the business-aviation apron, typically within fifty metres of the terminal. We arrive thirty minutes before chocks-off if it is a same-day positioning flight, or the evening before if the owner is staying overnight in Provence. The initial walk-around takes fifteen minutes: we photograph every bare-metal surface, measure oxidation depth with a gauge, and agree the scope with the captain or flight-department manager.

Masking begins as soon as the survey is done. We tape every painted edge adjacent to bare metal—the joint between the leading edge and the wing upper surface, the seam where the inlet ring meets the nacelle, the boundary around exhaust petals. Proper masking takes as long as the first polishing pass; rushing it means compound residue on paint, which then requires a solvent wipe and creates more work.

The polish itself moves in stages: cutting compound to remove oxidation and light corrosion, intermediate compound to erase the scratches left by the cutting stage, finishing polish to bring up the mirror gloss. Each stage requires a clean applicator and a separate microfibre cloth. Spinners and small exhaust cones finish in half a day; wing leading edges on a long-range jet can take two people two full days. Once the metal is mirror-bright, we apply sealant with a foam pad, let it haze for ten minutes, then buff it to clarity. The final step is a solvent wipe of any tape residue and a second walk-around to confirm every surface matches the reflection standard.

How do we co-ordinate with the Avignon handler?

The single handling agent at Avignon Provence manages the executive terminal, apron assignments, fuel, customs and airside access. We send our crew list and vehicle registration forty-eight hours before arrival; the handler prepares temporary passes and emails the security-gate procedure. On the day, we collect the passes at the terminal desk, drive airside, and park beside the aircraft stand.

Because the apron is compact and business-aviation movements are relatively light, the handler does not impose strict time limits. If the polish overruns by half a day, we telephone the duty manager and the aircraft stays on stand; there is no cascade of slot penalties or ramp fees. The handler does ask that we notify them the moment we know the aircraft will remain overnight, so they can log it in the daily movement sheet and arrange overnight security.

Water for rinsing compound residue comes from our own tanks; Avignon's water rules are typical for a French regional airport, and the handler prefers that we do not request a hose connection for a polish-only job. If the same visit includes a wash or decon, we arrange the water source during the initial coordination call. The handler also expects a fifteen-minute warning before engine start, so they can marshal the stand and ensure the apron is clear.

When should brightwork polish happen in the maintenance cycle?

Most flight departments schedule brightwork polish two to four times a year, aligning it with seasonal repositioning flights or pre-summer cosmetic preparation. Oxidation progresses faster in the first three months after paint, when the leading-edge mask is removed and bare metal is suddenly exposed to ultraviolet light and moisture. A polish and seal within that window sets a clean baseline and makes subsequent treatments shorter.

Operators who fly frequently between coastal and alpine environments—Côte d'Azur to the Alps, for example—see faster oxidation because of the salt and temperature swings. In those fleets, brightwork polish every ninety days keeps the metal ahead of visible dulling. Aircraft that spend weeks at a time on the ramp in the Rhône valley will show a grey haze on leading edges within sixty days if they were not sealed after the last polish.

Brightwork polish fits naturally into a complete detail: we wash and decontaminate the exterior, polish the paint, then move to the bare metal while the fuselage dries. Folding all three services into one multi-day visit at Avignon means the aircraft leaves with every surface—painted and bare—at show standard. If the calendar allows only a single-day stop, we prioritise the leading edges and inlets; those are the surfaces passengers see as they walk to the airstairs, and restoring them delivers the highest visual return for the time invested.

What do we need from the flight deck and the tech log?

Before we begin, the captain or engineer opens the tech log to the deferred-defects page so we can check whether any leading-edge de-ice panels, pitot probes or static ports are already written up. If a leading-edge section is flagged, we mask it and leave it untouched; polishing around a known fault avoids any suggestion that our work disturbed the system. We also ask whether the aircraft has had leading-edge paint or sealant repairs in the past six months: fresh paint needs thirty days to cure fully before we apply compound, and some sealants used in lightning-strike repairs should not be polished at all.

We request that all pitot covers and intake blanks remain in place until we finish masking. Once the aircraft is powered down and the GPU is connected, we ask the flight deck to leave the battery master off so that inadvertent contact with a probe heater switch does not energise a pitot tube while we are working inches away. If the cabin is occupied—owner staying aboard, or interior crew conducting a cabin detail in parallel—we coordinate with them to ensure no one opens a cabin window or door onto a freshly sealed leading edge; sealant haze transfers easily onto glass and requires solvent to remove.

At the end of the job, we walk the captain around the aircraft, show the before and after photographs on a tablet, and note the date and Hobbs time in our own log. That record helps the flight department track the interval to the next polish. If we find any leading-edge damage—stone chips, corrosion deeper than compound can remove, or a cracked de-ice boot—we photograph it, mark the station number, and mention it in the walk-around so the engineer can add it to the tech log if it is not already there.
