Exterior Dry Wash at Le Castellet (LFMQ)

Why do operators choose recurring dry wash at Le Castellet?

A mid-size or super-mid based here for the season—or returning every fortnight for race weekings—accumulates Mediterranean dust, pollen and the fine rubber particulate that drifts across from the circuit. Hydraulic mist collects on belly panels, and exhaust soot streaks back from the APU. A recurring dry-wash schedule keeps the aircraft presentable without the crew having to arrange a ferry to a wash bay elsewhere.

We build the interval around your flying pattern: every two weeks during the Grand Prix calendar, monthly through the quieter winter, or before each charter block. The tech log records the work, photographs go into your maintenance file, and the same technician learns the airframe—which panels streak, where the hydraulic weep persists, how much elbow work the nacelle lips need. Recurring work costs less per visit than ad-hoc call-outs, and you never arrive to find the aircraft dusty on the apron.

How does ramp access and airside logistics work at LFMQ?

Le Castellet has no dedicated FBO building, so the apron doubles as both parking stand and workspace. We hold permanent airside passes for the field and co-ordinate directly with the airport operations office, which manages stand assignments and ensures no conflict with inbound or outbound movements. If your aircraft sits on a remote stand near the hangars, we drive our kit out; if it is parked closer to the terminal building, we walk the fifty metres with a trolley.

The single runway—12/30, 1,545 metres—handles mid-size jets comfortably, and the field is not slot-coordinated, so there is rarely a queue that would force us off the apron mid-job. During Grand Prix weekends traffic density rises sharply, and we book our slot with the tower a day in advance to avoid clashing with a wave of arrivals. The plateau elevation of 1,391 feet means density altitude climbs on hot afternoons, but it has no bearing on a dry wash; we simply ensure the aircraft is chocked and the crew or handler has confirmed no engine run is planned while we are under the wing.

What changes at Le Castellet that affects exterior cleaning?

Three factors shape the work here. First, the field is no longer a customs airport; extra-Schengen PPF was withdrawn in June 2024, so only intra-Schengen flights are accepted. That narrows the mix to European charters and owner flights, which tend to stay longer than a quick fuel stop—giving us the three to eight hours a dry wash requires without pressure to release the stand early.

Second, the Circuit Paul Ricard sits immediately adjacent. Motorsport events—Formula 1 has returned since 2018, plus endurance and historic races—generate intense peaks of business-aviation traffic. The apron fills with Challengers, Globals and Falcons, often parked wingtip to wingtip. We schedule carefully: a dry wash begun on Friday morning will finish before the afternoon's practice session brings the next wave, and we avoid Sunday race-day entirely unless the aircraft departs Monday and the crew wants it clean for the return leg.

Third, hangar space exists. Five aircraft hangars were built during the 2001 modernisation, and the airport rents them out. If winter weather turns—mistral winds or heavy dew—we can move a dry wash indoors, though most months the plateau enjoys enough sunshine that ramp work is faster and the natural light shows every streak we might have missed.

What does the dry-wash process include, and what does it leave out?

We clean the entire exterior envelope: fuselage from radome to tail cone, both wings upper and lower, empennage, nacelles, belly panels and the main and nose landing gear. Bug strikes on the leading edges and windscreen come off with a dedicated remover; exhaust soot around the APU outlet and engine pylons requires a heavier surfactant and microfibre bonnets changed every two square metres to avoid redepositing carbon. Hydraulic film on the belly and gear-bay lips is degreased, and we wipe down all exterior lights, static ports (no-touch) and the pitot tube covers if they are already fitted.

Brightwork—leading-edge strips, nacelle lips, windscreen frames—receives a light polish to lift oxidation, but this is not a full metal restoration; if the strips are pitted or heavily corroded, that work belongs in a single-stage polish service, not a dry wash. We do not open panels, we do not touch avionics fairings beyond a damp wipe, and we do not apply sealant or paint touch-up. The result is a clean aircraft, not a restored one, and the process leaves no standing water or chemical runoff on the apron.

How do you document the work and deliver the photo report?

Every dry wash generates a written report: start and finish times, products used, areas that needed extra attention, and any exterior defects we noticed—a cracked lens, a weeping hydraulic actuator, a missing screw on a belly panel. The report goes into your tech log as a non-maintenance entry, and a copy travels with the invoice. Photographs are taken before we begin, during the process to show problem areas, and after completion. The set runs to thirty or forty images for a super-mid, more if the belly was heavily soiled or if you ask us to document a specific panel for your own maintenance tracking.

We deliver the photo package within twenty-four hours, either by email or uploaded to your flight department's shared drive if you provide a link. Some charter operators want before-and-after pairs to show the client; others want only the final walk-around shots for their own records. We ask at the pre-work briefing and tailor the shoot accordingly. The images are time-stamped, and if you need them geo-tagged or captioned for an insurance file, we can arrange that as well.

When should a dry wash happen between legs or overnight at Le Castellet?

Timing depends on your turnaround. If the aircraft lands mid-morning, refuels, and departs at sunset, a dry wash will not fit; we need a minimum of three hours for a light jet, five for a super-mid, eight for a Global 7500 or a Falcon 8X. If the crew overnights and the departure slot is after noon the next day, we start at first light—0700 in summer, 0800 in winter—and finish with an hour to spare for the walk-around and any last-minute catering load.

For aircraft staying several days, we prefer to wash on the second afternoon, after the first flight's bugs and soot have had time to bake on but before the owner or charter client boards again. If the aircraft is parked for a week or more, we wait until two days before departure so it stays clean for the next leg. During Grand Prix weekends the apron is crowded and the schedule rigid; we book forty-eight hours ahead, confirm stand location with ops, and work overnight if daytime slots are full. The field has no curfew, so a midnight-to-dawn wash is possible, and the plateau's dry air means the fuselage dries quickly even without sun.
