Cabin Disinfection at Zurich (LSZH)

Why disinfect the cabin at Zurich between legs?

Charter operators running sequential trips through Zurich face a simple problem: the previous passenger's world should not greet the next. A medical evacuation leaves biological traces; a long transatlantic positioning collects galley spills, lavatory contact, and recirculated cabin air that smells tired. Cabin disinfection resets the environment in the window between block-in and the next PPR slot.

We sanitise armrests, tray tables, seat controls, door latches, galley surfaces, lavatory fixtures, and every switch a hand touches. The air path—vents, gaspers, and grilles—receives the same attention, because disinfectants that work on surfaces do nothing for odour molecules riding the ECS loop. Odour neutralisation is always included, whether the source is catering, smoke residue, or biological. You receive a certificate of treatment and a time-stamped photo report before we sign the tech log, so the next leg begins with evidence in the folder and nothing lingering in the cabin.

What changes at Zurich that affects cabin disinfection timing?

Zurich operates under one of the strictest night curfews in Europe: 23:30 to 06:00 local, enforced since July 2010, with no routine exceptions. Slot-allocation curfews close arrivals at 23:00 and departures at 22:46 CET, which means any aircraft on the ground overnight sits from late evening until the morning departure wave. That window—roughly 23:30 to 05:30—is when most overnight detailing happens, but cabin disinfection for a morning departure usually begins earlier, during the evening turnaround, because the work is faster and the cabin can air out before boarding.

The airport sits at 1417 feet elevation, nine kilometres from central Zurich, and offers three runways: 16/34 at 3700 metres, 14/32 at 3300 metres, and 10/28 at 2500 metres. Handling agents present at the airport operate from the General Aviation Center on Bimenzaeltenstrasse; Jet Aviation's GAC FBO lists interior cleaning among its services and keeps hours from 06:00 to 22:00 daily. We coordinate with the handler for airside escort, GPU continuity, and access to potable water if a post-disinfection rinse of galley fixtures is part of the scope. Zurich is slot-coordinated, so every minute of ramp time is planned; we confirm start and finish times by email the day before, and we do not overrun.

What does the disinfection process cover inside the cabin?

The process begins with a walk-through to identify high-touch zones and odour sources. We treat seats—armrests, headrests, recline controls, lumbar switches—plus every tray table, latch, and reading-light bezel. Galley counters, refrigerator handles, coffee-maker panels, and waste-bin lids receive disinfectant; lavatory sinks, taps, flush buttons, door locks, and grab rails follow. If the aircraft has a divan or club seating, we treat cushion piping, bolsters, and any stitched seam that collects hand oils.

Air vents and gaspers are wiped with lint-free applicators; disinfectant vapour does not reach into ducting, but surface treatment of grilles and bezels removes the film where bacteria colonise. Odour neutralisation uses an enzymatic spray that breaks down organic molecules rather than masking them; smoke, galley grease, and biological odours all respond. The final step is a visual check under galley-unit lighting and a second pass on any surface that shows streaking or residue. We photograph the completed cabin from three angles—forward, mid, aft—and produce a one-page certificate with aircraft registration, date, start and finish times, and the disinfectant batch number.

How does cabin disinfection fit into a Zurich turnaround?

A typical disinfection takes one to two hours, depending on cabin size and configuration. An eight-seat light jet with a single lavatory and a two-bay galley finishes in an hour; a fourteen-seat super-midsize with a full galley, two lavatories, and a divan stretches toward ninety minutes. We start as soon as the handler confirms GPU connection and the cabin door is open, so the clock runs in parallel with refuelling and any line maintenance.

For same-day turnarounds, we arrive thirty minutes before block-in, meet the handler on the apron, and begin the moment the passengers disembark. If the next departure is inside three hours, disinfection and a dry wash of the exterior can both finish with forty minutes to spare for catering and pre-flight. For overnight aircraft, we usually begin after 20:00, complete by 22:00, and leave the cabin ventilated overnight so any residual solvent odour dissipates before the morning departure. The curfew makes late starts impossible, so we confirm the slot and the handler's apron access in writing two days ahead.

Which disinfectants do you use, and are they safe for OEM cabin materials?

We use quaternary-ammonium and hydrogen-peroxide-based disinfectants that appear on the airworthiness-approved product lists published by Gulfstream, Bombardier, Dassault, Embraer, and Textron. Every product carries an SDS and a material-compatibility matrix; we cross-check the matrix against the aircraft's cabin-materials schedule before the first application. Leather, Alcantara, wool carpet, lacquered veneer, and anodised brightwork all tolerate the disinfectants we carry, provided dwell time and dilution follow the label.

We do not spray disinfectant onto avionics panels, touchscreens, or any surface within five centimetres of a static port or air-data sensor. Those areas receive a dampened lint-free wipe with the applicator wrung nearly dry. Galley units with stainless or composite surfaces tolerate full-strength application; wood veneer and open-pore finishes receive a diluted formula. If a material is not in our compatibility database—a bespoke inlay, for example, or an aftermarket upholstery—we ask for the completion certificate or the STC paperwork and defer treatment of that surface until we have manufacturer guidance.

Do you provide documentation after the disinfection is complete?

Yes. Every disinfection concludes with a certificate of treatment and a photo report, both emailed within two hours of finish time. The certificate lists the aircraft registration, date, location, start and finish times in UTC, the disinfectant product name and batch number, and the areas treated. It carries our company signature and is written in English; if you need a German or Italian translation for a local health authority, we provide that on request at no charge.

The photo report includes three cabin angles—forward looking aft, mid-cabin at galley height, and aft looking forward—plus close-ups of any area that required extra attention: a galley spill, a lavatory stain, or a seat with visible soiling before treatment. The photos are time-stamped and geotagged, stored in our job archive for two years, and available for download as a ZIP file. If you operate under an IS-BAO or ARGUS audit, the certificate and photos slot directly into your SMS documentation without reformatting.
