Ceramic Coating at Buochs (LSZC)

What changes at Buochs for a multi-day ceramic application?

Buochs sits at 1,475 feet elevation in the valley beside Stans, with a single 2,000-metre runway serving both civil traffic and the Pilatus Aircraft factory. The airfield began as a Swiss Air Force base—a sleeping base from 2004 and closed to regular military use at the end of 2017—and is now operated by the civil company Airport Buochs AG. Underground aircraft caverns and hangars remain on site, and the factory uses the field for test and delivery flights of PC-12 and PC-24 aircraft. Outside pilots face taxiing restrictions around the factory perimeter, so ground movements follow a defined route to the hangar where the ceramic work takes place.

The elevation and alpine weather mean cold-soaked surfaces in winter and rapid temperature swings in spring and autumn. Paint correction begins only after the aircraft has stabilised at hangar temperature; rushing that step traps moisture under the ceramic layer. The three-to-six-day schedule includes curing time in climate-controlled conditions, so the slot must be booked well ahead. No handling agents are listed at the airport in the usual sense; coordination for hangar access, GPU, and airside escort runs through Airport Buochs AG and the on-site infrastructure inherited from the military era.

How does the ceramic process differ from a polish-and-seal visit?

A single-stage polish restores gloss and removes light oxidation, then a carnauba or synthetic sealant sits on top for three to six months. Ceramic coating is a chemical bond: two layers of SiO₂-based liquid cure into a semi-permanent shell over corrected paint, brightwork, and glass. The shell is harder than wax, hydrophobic enough that water sheets off in seconds, and resistant to the glycol in Type I and Type IV de-icing fluid. That resistance matters at an alpine field where winter operations are routine.

The preparation is more invasive. Every panel is decontaminated with a clay bar or chemical decon to lift embedded rail dust, brake dust, and exhaust particles. Paint is then machine-corrected to remove swirls and light scratches; the ceramic magnifies any defect left behind, so this step cannot be shortened. Leading edges, nacelle lips, and winglets receive the same correction before the first ceramic layer goes on. The second layer follows six hours later, and the aircraft stays in the hangar another 24 to 48 hours while the coating cross-links. You leave with a maintenance plan that maps out the next two to three years: wash intervals, approved shampoos, and the inspection schedule that keeps the warranty valid.

Why do operators choose Buochs for a week-long detail?

Most ceramic bookings at Buochs are tied to delivery flights or pre-sale preparation. A fleet bringing a PC-24 out of the factory next door will add ceramic coating while the aircraft is still on-site, folding the detail into the acceptance schedule. Charter operators preparing an ultra-long-range jet for sale want the protection documented before the pre-buy survey, and the hangar space inherited from the air-force years can accommodate even a Global 7500 or Falcon 8X nose-in.

The other draw is privacy. Buochs does not host scheduled airline traffic or a busy FBO ramp; the apron sees Pilatus test aircraft, a handful of based business jets, and visiting turboprops. A six-day ceramic application happens behind hangar doors, away from the public terminal and without the interruptions common at a major hub. The same underground infrastructure that once sheltered fighter jets now offers climate-controlled space where temperature and humidity stay constant—critical when the ceramic layer is curing and any dust or pollen will mar the finish.

What does the airport expect from a third-party detailing crew?

Airport Buochs AG manages the civil side of the field, and any outside crew working airside needs coordination through the airport office before arrival. Taxiing restrictions around the Pilatus factory mean the detailing team cannot move the aircraft without an escort; that escort is arranged during the booking, and the route to the hangar is briefed on the day. The crew must carry an airside pass valid for Swiss airports or be escorted at all times—Buochs does not issue temporary passes at the gate in the way a busy international field might.

Hangar access includes GPU and compressed air; waste-water disposal follows cantonal environmental rules, so all wash water and polish residue are captured and removed in sealed containers. The team brings its own lighting rigs, extension leads, and mobile workstations; the hangar has power points, but not the density of outlets found in a modern FBO facility. The tech log stays with the flight crew or handler throughout the detail, and no entry is made unless a panel is opened for inspection—ceramic application is non-invasive and leaves no record in the log. A photo report goes to the chief pilot or flight-department manager at the end, showing corrected paint, applied coating, and the hydrophobic test on the windscreen.

How does recurring work at Buochs fit into a fleet maintenance calendar?

Ceramic coating is a two-to-three-year product, so the first application is often scheduled around a repaint, a pre-purchase inspection, or the off-season lull in charter flying. After that, the aircraft returns for a maintenance wash every four to eight weeks—shorter intervals in winter when de-icing fluid and road-salt spray accumulate on the belly and gear bays, longer in summer when the hydrophobic layer sheds rain and dust without help. The wash takes half the time it would on uncoated paint, because contaminants have not bonded to the surface.

At the two-year mark the coating is inspected under LED work lights: if the hydrophobic effect has faded on the nose, leading edges, or engine nacelles—the zones that see the most abrasion—a single-layer top-up restores protection without repeating the full correction process. If the fleet operates year-round from alpine or northern European airports, where Type IV fluid and UV exposure are both high, the top-up may be needed at eighteen months. The maintenance plan issued at the end of the first application includes a decision tree: wash intervals, approved products, and the inspection points that trigger a top-up or a full re-application. That plan travels with the aircraft and is updated in the warranty document each time the coating is serviced.

What documentation does the operator receive after a ceramic application?

The photo report begins with before images under work lights, showing swirls, oxidation, and any paint defects found during the walk-around. After decontamination and correction, a second set of images documents the prepared surface—this is the baseline for the warranty. Once both ceramic layers have cured, close-up shots capture the gloss on the fuselage, the bead test on the windscreen, and the coated brightwork on nacelle lips and leading edges. A short video of water sheeting off the wing is often included; it is a simple proof that the hydrophobic effect is working, and fleet managers use it in pre-flight briefings to explain why the aircraft stays cleaner between washes.

The maintenance plan is a printed document listing approved wash shampoos—pH-neutral, no wax or sealant additives—and the inspection schedule. It names the products used, the batch numbers of the ceramic coating, and the curing conditions in the hangar. The warranty runs for two or three years depending on the product tier, and it remains valid only if the aircraft is washed with approved methods and inspected at the stated intervals. A digital copy of the plan, the photo report, and the warranty certificate are sent to the flight-department manager within 24 hours of the aircraft leaving Buochs; the printed folder travels in the cabin so the next handler or detailing crew knows what is already on the paint.
