Complete Detail at Linz (LOWL)

What changes at Linz for a complete-detail turnaround?

Linz sits at 980 feet, ten and a half kilometres southwest of the city, with a single 3,000-metre runway and a separate general-aviation terminal operated by the General Aviation Center. The airport closes every night at 23:00 local, reopening at 05:30 on weekdays and 06:00 at weekends; aerodrome administration and customs follow the same hours. That curfew shapes the work window: a multi-day detail must either finish each evening by 23:00 or be arranged on request with the GAC if an overnight stay on stand is acceptable.

The airfield is also a military base—Fliegerhorst Vogler lies south of the runway—so expect security procedures and occasional military movements on the airside. The GAC coordinates passport and customs checks, refuelling, cleaning and VIP service from its own apron, which keeps business-aviation traffic separate from the airline terminal. Linz is IATA Level 2, schedules facilitated rather than fully slot-coordinated; schedule requests go to SCA with a copy to the airport, but slots are not required and PPR is straightforward.

Handlers at the airport expect third-party specialist crews to arrive with their own airside escort or to be met at the security gate. We carry our own equipment, our own water and our own insurance; the GAC apron has GPU and ground-power access, so the aircraft can remain live for avionics and environmental systems throughout the detail if the tech log allows it.

Why does a complete detail take two to five days?

Because the work is sequential and each stage must cure or dry before the next begins. We start with a dry wash or rinseless exterior clean to lift dust, exhaust residue and de-icing salts without scratching the paint. Once the surface is clean and dry, we apply a chemical decontamination treatment to pull embedded iron particles, tar and industrial fallout from the clear coat—contaminants that a wash alone will not shift. The paint is then clayed by hand, panel by panel, to remove anything still bonded to the surface.

Single-stage machine polishing follows: we correct light oxidation, swirl marks and water spots, working in overlapping passes with a finishing polish that leaves a uniform gloss. Brightwork—nacelle lips, winglet leading edges, windscreen surrounds—is polished separately with a metal-safe compound. While the exterior cures, the cabin team works through the interior: vacuuming, shampooing soft furnishings, cleaning and conditioning all OEM materials, treating galley and lavatory surfaces, and disinfecting high-touch areas in the flight deck.

The final half-day is reserved for a second exterior inspection, a no-touch wipe of avionics covers and static ports, and the photographic report. If weather turns or if contamination is heavier than the pre-arrival survey suggested, the schedule stretches; if the aircraft is already well-maintained and the interior is light, we can compress the work into two full days.

What does the photographic report include?

A time-stamped record of the aircraft before we touch it and again at handover, delivered as a digital album with captions and close-ups of any area that required extra attention. We photograph the fuselage from nose to tail in natural light, both sides, the belly as far as the gear bays allow, the upper surfaces from a ladder, and every control surface, nacelle and winglet. Inside, we document cabin seating, side panels, the galley, the lavatory, carpets, and the flight-deck seats and glare shield.

The report is not marketing material; it is evidence. Pre-buy inspectors use it to confirm that paint correction was carried out without cutting through the clear coat. Sellers include it in the aircraft's logbook file to show prospective buyers that the airframe was professionally maintained. Fleet managers use the before images to track how quickly contamination builds up on a particular route or during a particular season, then adjust the cleaning interval accordingly. If a dispute arises about the condition of a cabin material after detailing, the photographs settle it.

How does Austrian weather affect paint and cabin between details?

Linz has a temperate continental climate: cold winters with frequent de-icing, warm summers with afternoon convection, and year-round humidity that accelerates the bonding of airborne contaminants to paint. Aircraft operating through Central Europe pick up iron particles from rail-freight corridors, road dust from the Danube valley, and biological matter—pollen, tree sap, insect strikes—during the growing season. All of it embeds in the clear coat if left for more than a few weeks.

Winter brings its own load: Type I and Type IV de-icing fluids leave a sticky residue on the belly and lower fuselage, and road salt thrown up by ground vehicles during apron movements coats the gear bays and nacelle interiors. If the aircraft sits cold-soaked overnight after a flight, condensation forms on the paint and traps whatever settled during taxi. Inside, humidity works its way into carpets and soft furnishings, and cabin air that is not fully cycled between legs allows odours to build up in the environmental system.

A complete detail once or twice a year resets the baseline: the paint is decontaminated and protected, brightwork is sealed, and the cabin is deep-cleaned and disinfected. Operators who run a regular programme at Linz—quarterly or seasonal washes with an annual full detail—find that each turnaround takes less time because contamination never has the chance to bond hard.

Can you complete-detail an aircraft that is AOG or waiting for parts?

Yes, and the economics often make sense: the aircraft is already on the ground, the handler has arranged parking, and the downtime can be used for something other than watching the tech log. We coordinate with the maintenance provider to confirm that the airframe will remain accessible—no cowlings removed, no scaffolding around the fuselage—and that we can work around any open panels or static-discharge points. If the aircraft is waiting for a part that will take a week to arrive, a complete detail fits neatly into the gap.

The one constraint is power: we need the cabin environmental system running to control humidity during interior work, and we need the flight-deck live to avoid any risk of moisture ingress into avionics bays. If the aircraft cannot be powered from a GPU or if the batteries are being replaced, we defer the interior detail until the electrical system is serviceable again. The exterior work—wash, decontamination, polish, brightwork—can proceed regardless, as long as the apron is dry and the temperature is above five degrees Celsius for the compounds to cure properly.

How do you manage a complete detail for an aircraft based at Linz year-round?

We treat it as scheduled maintenance: the detail goes into the aircraft's annual plan at the same interval as a phase inspection, and the date is fixed three months in advance so the operator can route the aircraft back to Linz with an empty leg. For a fleet programme, we stagger the schedule so that one airframe comes through every quarter; that way the cabin crew and the chief pilot see the process once and know what to expect for the rest of the fleet.

The GAC is notified four weeks ahead with the registration, the MTOW, the requested arrival and departure days, and a note that the aircraft will need apron parking and GPU access for up to five days. We send our own team from Italy with all equipment and consumables; the handler provides the airside escort and arranges customs if the aircraft is arriving from outside Schengen. If the operator wants the aircraft to remain in the hangar rather than on the apron—common in winter or if the paint is fresh—we coordinate hangar availability directly with the GAC and adjust the schedule to fit their door-open hours.

Recurring work at a single base has a rhythm: we learn the aircraft's quirks, we know which cabin materials need extra care, and we can track how the paint ages over successive details. The photographic reports build into a visual maintenance history that is worth having when the aircraft eventually goes to market.
