Brightwork Polish at Palma de Mallorca Airport (Son Sant Joan) (LEPA)

Why does brightwork oxidise faster at Palma de Mallorca Airport?

The airport sits 27 feet above sea level, eight kilometres from Palma city centre and less than two from the Mediterranean shore. Every arrival and departure draws salt-laden air across nacelles, leading edges and spinners; after shutdown the salt film dries into a hygroscopic crust that holds moisture against bare aluminium or stainless steel. Ultraviolet flux is high April through October—the months when fire category rises to 9 on request—and parked aircraft on the General Aviation apron receive direct exposure most of the day.

Oxidation begins as a haze, then progresses to chalky patches and finally to pitting that no amount of polishing will erase. Inlets and spinner domes show it first because they face the airstream; leading edges follow, especially on winglets where the cheat line meets bare metal. Exhaust petals and thrust-reverser cascades develop heat tint that salt accelerates into brown scale. A regular brightwork cycle—two to four times a year—removes the oxide before it etches, and the sealant coat we apply afterward gives hydrophobic protection for three to five months depending on utilisation.

What changes at Palma de Mallorca Airport (Son Sant Joan)?

Palma de Mallorca Airport is the only H24 field in the Balearics and is slot-coordinated year-round at Level 3, with real-time requests handled in H36 mode. Runway 06L/24R measures 3270 metres; 06R/24L is 3000 metres. The General Aviation Terminal lies on the east side of the airport, served by three handling agents: Sky Valet Palma de Mallorca (Gestair), Mallorcair and AviaVIP Palma (Aviapartner Palma de Mallorca FBO).

Because slots govern every movement, a brightwork appointment must align with your departure PPR and any weekend State-flight window active 1 May through 31 October. Handlers expect at least seventy-two hours' notice for a multi-day stand and will ask whether you need GPU, air-start or potable service while the aircraft is down. Summer traffic raises apron density; the fire category increase to 9 means quicker emergency response but also tighter ramp discipline. We collect an airside escort from the handler each morning, bring our own deionised water in road-legal containers—airport hydrant water is potable but leaves mineral spots on polished metal—and return the aircraft to the handler's care each evening with gear pins, pitot covers and intake socks in place.

How long does a full brightwork polish take at Palma de Mallorca?

One day covers a light jet with minimal exposed metal—typically spinner domes, exhaust rings and window surrounds. A super-midsize with bare leading edges on wing and horizontal stabiliser, plus full inlet rings and nacelle brightwork, requires two days. Ultra-long-range aircraft carrying additional trim—polished fairings aft of the engines, stainless belly panels, extended winglet caps—push the schedule to three days. We work daylight hours to see surface defects clearly; artificial light hides micro-scratches that reappear in sunlight.

Each surface is compounded in three stages: coarse cut to remove oxidation and light corrosion, medium cut to erase compounding marks, fine polish to bring up the mirror. Spinners and inlet rings come off the aircraft when fasteners allow; we polish them on trestles, which is faster and gives a more uniform finish. Leading edges are worked in place, masked at the paint transition to avoid cutting through the cheat line. Exhaust petals are drawn out when the tech log permits, or polished in situ if the engine has hours remaining before the next inspection. After final buffing we apply a polymer sealant that crosslinks in thirty minutes and cures fully overnight, so the aircraft can depart the following morning without streaking.

What do handlers at Palma de Mallorca expect from a detailing crew?

Handlers want a written scope of work forty-eight hours before we arrive: which panels will be removed, whether we need trestles or scaffolding, and the latest time each day we will clear the stand. They provide the airside escort—one person for a two-technician team—and expect us to follow that escort everywhere, even to the waste-disposal point. We bring our own liability certificate naming the handler and the airport authority; some FBOs ask for method statements covering chemical use and waste handling.

Compounds and polishes generate fine aluminium dust that must not enter gear bays, static ports or avionics cooling vents. We mask every opening and lay absorbent mats under the work area; at the end of each day we vacuum the mats, bag the waste and hand it to the handler's ground crew for disposal as non-hazardous solid waste. Any spill on the apron is wiped immediately—jet fuel dissolves wax sealant, and hydraulic fluid stains polished metal. The handler logs our arrival and departure in the movement record and notes any panels left open overnight. If the aircraft will be cold-soaked or requires deicing before departure, we inform the handler so they can schedule Type I or Type IV fluid without waiting for the sealant to cure.

Which surfaces benefit most from brightwork polishing?

Leading edges see the highest kinetic energy and collect the most impact damage—bug strikes, rain erosion, dust abrasion. Oxidation starts in the microscopic pits left by each impact; polishing removes the damaged layer and exposes fresh metal. Inlet rings and spinner domes are next: they channel high-velocity air and show every imperfection as a dull spot in the reflection. Exhaust surfaces endure thermal cycling and combustion residue; polishing strips the heat tint and restores the stainless to its original lustre.

Window surrounds and bright trim are cosmetic but highly visible during walkarounds and in cabin photos. Polished frames around windscreens and passenger windows lift the entire appearance; dull surrounds make even a clean airframe look tired. Winglet caps and nacelle strakes are optional brightwork on some types, often specified by completion centres to match the exterior scheme. We polish them whenever bare metal is exposed, because a patchy finish—half mirror, half haze—draws the eye more than uniform dullness. After polishing, the sealant coat bonds to the oxide-free surface and slows the return of tarnish by four to six months, depending on whether the aircraft operates in coastal or inland environments.

Can brightwork polish be combined with other detailing at Palma de Mallorca?

Yes, and the combination is efficient because the aircraft is already on stand and the handler has allocated the ground time. A common pairing is a dry wash of the fuselage and wings on day one, brightwork polish on day two, and a single-stage paint polish on day three, delivered as a Complete Detail. The dry wash removes the salt film and general grime so that polishing compounds do not scratch the paint; the brightwork comes up to mirror finish; the paint polish follows, blending the cheat line into the polished leading edge without a visible step.

Another sequence starts with a rinseless exterior wash—useful in summer when water restrictions tighten—followed by brightwork and then a cabin deep-clean while the sealant cures. The handler provides GPU throughout, and we coordinate with any avionics shop or maintenance provider also on site. Scheduling all work in one visit saves multiple airside-escort fees, multiple handler charges and multiple slot requests. We send a consolidated timeline to the handler and copy the captain or chief pilot, so everyone knows when the aircraft will be ready for the next leg.
