Brightwork Polish at Nîmes-Alès-Camargue-Cévennes (LFTW)

Why does brightwork need regular polishing at a Mediterranean airport?

The climate at Nîmes-Alès-Camargue-Cévennes is hot, dry and unforgiving. The field sits at 309 feet on the Costières plain with a reference temperature of 33.1 °C, and summer heat accelerates oxidation on every bare-metal surface. Leading edges that gleamed after the last polish dull within weeks; inlet rings develop a grey haze; exhaust stains bake into the aluminium. Even aircraft that spend most of their time farther north pick up UV damage quickly during a single Mediterranean summer.

Oxidation is not only cosmetic. A chalky leading edge disrupts laminar flow and adds drag; tarnished inlets make walk-around inspections harder because corrosion and fatigue cracks hide in the dull surface. Regular polishing—two to four times a year—removes the oxide layer before it etches deeply, keeps the metal smooth and reflective, and gives the engineer a clean surface to inspect. We finish every session with a sealant application that slows the next cycle of oxidation, buying the aircraft a few extra weeks of gloss between services.

What changes at Nîmes-Alès-Camargue-Cévennes for a brightwork session?

The field has a single concrete runway—18/36, 2,443 metres, PCN 63—and apron capacity is deliberately limited. The airport operator Edeis lists only three remote stands across 52,875 square metres of apron, and the AIP states that both IFR and VFR aircraft wishing to stop over are admitted only with prior Edeis authorisation. For a brightwork polish that occupies a stand for one to three days, advance coordination with the operations office (nimes.ops@edeis.com, OPS frequency 131.7 MHz) is not a courtesy; it is a requirement. We arrange the parking slot as soon as the owner confirms dates, and we stay in contact with Edeis throughout the session to ensure the stand remains allocated.

Handling agents present at the airport include ExecuJet, part of the Luxaviation group and FBO partner of Edeis. The operator manages all personalised requests through the same operations contact, so every detail—GPU, airside escort, waste disposal, even the timing of our access—flows through one office. The process is straightforward once the slot is confirmed, but it cannot be assumed. The distance to Nîmes is nine kilometres SSE, close enough for crew transport but far enough that last-minute changes are inconvenient. Plan the stopover early.

How do you polish leading edges without damaging the surface?

We work by hand with graduated compounds and soft bonnets, never a rotary buffer near a leading edge. The wing and stabiliser leading edges are thin, often with erosion boots or anti-ice strips bonded to the metal; too much pressure or heat will delaminate the boot or dish the aluminium. We start with a fine cutting compound to remove oxidation and light corrosion, then step through two polishing grades to build the mirror finish. Each pass is checked under raking light so we see every swirl mark before moving to the next stage.

Engine inlet rings and spinners see different abuse—exhaust soot, hydraulic mist, de-icing fluid residue—so the prep is more aggressive. We decon the surface first, then polish with the same three-stage process. Exhaust and thrust-reverser surfaces often carry baked carbon; we remove it with a solvent wipe before polishing so we do not grind the carbon into the metal. Window surrounds and bright trim are polished last, using the finest compound only, because the tolerances around glass and paint are tight. The final step on every surface is a polymer sealant that fills the microscopic pores in the aluminium and leaves a hydrophobic layer. It does not stop oxidation forever, but it doubles the time before the next session.

What does the handler expect when a third-party detailing crew is on the ramp?

Edeis runs a tidy operation and expects the same from everyone airside. We arrive with our own airside passes or arrange escort through the ops office; we do not wander the apron or use the aircraft as a ladder without the handler knowing. Waste water from polishing—grey with compound residue and dissolved aluminium oxide—goes into our recovery tank, not onto the stand. Nîmes has specific rules about water discharge, and we follow them without negotiation. Rags, spent bonnets and empty compound bottles leave the apron in our van at the end of each shift.

The ops office appreciates a simple courtesy: a morning text when we start and an afternoon message when we finish. If the session runs into a second or third day, we confirm the stand is still allocated and that no movement is planned. The handler's job is to keep the apron flowing; ours is to stay out of the way and finish on time. When both sides communicate, the brightwork gets done and the aircraft departs on schedule.

How do you document the work for the tech log?

Every brightwork session closes with a written report and a set of before-and-after photographs. The report lists each surface polished—wing leading edges, stabiliser leading edges, inlet rings, spinners, exhausts, window surrounds—and notes any damage we found: corrosion pits, impact nicks, cracks in erosion boots, delamination. We do not repair structural issues, but we photograph them and mark the frame station or panel number so the engineer knows exactly where to look.

The photo set includes wide shots of each major surface and close-ups of any defect. We shoot in natural light when possible because flash hides the true condition of the metal. If we remove corrosion or a deep stain, the before-and-after pair goes into the report so the flight department has a record of the improvement. The document is emailed as a PDF within twenty-four hours of completion, and a signed copy can be left in the cockpit for the tech log if the chief pilot prefers. The goal is simple: the next engineer to inspect the leading edges should know what was done, when, and what still needs attention.

When does brightwork polish fit into the operational schedule?

The ideal window is between owner legs, when the aircraft will sit for two or three days anyway. A one-day brightwork session—common on a super-midsize jet with modest amounts of bare metal—fits neatly into a forty-eight-hour gap; a three-day session on an ultra-long-range aircraft with extensive leading edges and large inlet rings needs a longer break or a planned maintenance stopover. We start as soon as the aircraft is on stand and the GPU is connected, and we work through the day so the cabin crew can provision or rest without our presence inside.

Brightwork polish is often bundled with a single-stage paint correction or a dry wash, because the leading edges look incongruous when they gleam and the fuselage is dull. If the schedule allows, we complete the metal first—it is the slower, more labour-intensive job—then move to the paint. The result is an aircraft that looks coherent from nose to tail. Operators who plan a Mediterranean summer season often book the service in late spring, before the heat and UV load become relentless, then again in autumn before the aircraft repositions north. Two sessions a year keep the brightwork ahead of oxidation; four sessions a year keep it perfect.
