Complete Detail at Ljubljana Jože Pučnik (LJLJ)

Why does an aircraft need a complete detail at Ljubljana?

Paint collects more than rain. Over six or twelve months, exhaust residue from ground equipment, de-icing fluid, insect protein, tree pollen and industrial fallout bond to the clear coat. Left alone, they oxidise the paint and dull the cheat line. Inside, high-touch surfaces—armrests, galley counters, lavatory fixtures—accumulate oils and microbial load that a turnaround wipe cannot remove.

Complete detail reverses that. We clay the fuselage and wings to lift embedded contamination, then machine-polish to restore gloss and hydrophobic behaviour. Brightwork—nacelle lips, windscreen frames, gear-door edges—is polished by hand. The cabin receives a full detail: every surface cleaned to OEM specification, leather conditioned, carpets extracted, air vents and plenum grilles vacuumed, hard surfaces disinfected. The result is an aircraft that looks and smells as it did at delivery, which matters when a buyer steps aboard or a charter client expects flagship condition.

What changes at Ljubljana Jože Pučnik?

The field sits 1,273 feet above sea level, 26 kilometres north-west of Ljubljana. A single runway—12/30, 3,300 metres—handles all movements; runway 30 is equipped with ILS category IIIb, useful during the autumn and winter months when fog forms in the basin. Fraport Slovenija, the airport operator, also runs the General Aviation Centre, now relocated into the main passenger terminal. You follow signs for 'VIP Services, General Aviation'; the staff security checkpoint opens at 06:00 and closes at 21:00, but outside those hours airside access is possible via checkpoint R1 if you notify the Security Operations Centre in advance.

The airport is not slot-coordinated, yet Fraport Slovenija requires a PPR for general-aviation movements at least twenty-four hours before arrival. Handling agents present at the airport arrange stand, GPU, water and customs or police assistance when needed. Out-of-hours GA service is charged in thirty-minute increments, so a weekday arrival between 06:00 and 21:00 keeps costs predictable. For a multi-day detail we usually work in a hangar; if none is available, we detail on the ramp and tow the aircraft under cover each evening.

How long does a complete detail take at LJLJ?

Two to five days, depending on aircraft size, paint condition and cabin complexity. A super-midsize jet with six months of European flying and a well-maintained interior sits at the lower end; an ultra-long-range aircraft returning from a trans-Atlantic charter season, with bellies stained by de-icing fluid and cabin carpets trafficked by rotating crews, takes the full five.

We start with the exterior: pre-rinse or dry-wash, decontamination clay on all painted surfaces, then a single-stage machine polish working in one-metre squares. Brightwork comes next—nacelles, windscreen surrounds, wing leading edges. While the polish cures we move inside: cabin detail, galley and lavatory deep-clean, cockpit no-touch avionics wipe-down, leather conditioning, carpet extraction. On the final morning we apply a spray sealant to the fuselage, polish the static ports and pitot covers, photograph the aircraft in six standard angles, and hand you a USB drive with before-and-after images and a checklist signed by the lead technician.

What does the climate around Ljubljana do to the aircraft?

Ljubljana sits in a temperate zone with four distinct seasons. Winter brings snow, freezing rain and Type I or IV fluid; residue from both collects along the belly, gear bays and winglets, then bakes on during the first warm spell in spring. Spring and summer deliver pollen—linden and birch especially—and insect strikes on the leading edges and nacelle inlets. Autumn fog returns, along with road-salt spray if the aircraft has been parked near service vehicles.

All of it degrades the hydrophobic layer that keeps rain beading. Once that layer fails, water sheets across the paint, carrying dirt into panel gaps and around fasteners. Decontamination clay pulls the bonded contamination free; the polish that follows re-levels the clear coat and restores the hydrophobic finish, so the next rain event cleans the aircraft rather than staining it. Inside, the same seasonal cycling—heating in winter, air-conditioning in summer—drives condensation into seat-rail channels and plenum ducts, creating odour. A complete detail reaches those spaces.

How do you manage airside access and the photographic report?

The handling agent requests the stand or hangar and arranges our airside escort if we are working outside the General Aviation Centre's secure area. We carry our own equipment—clay bars, dual-action polishers, microfibre, disinfectant, extractor—so we do not depend on FBO supplies. If mains power is unavailable on the ramp we run from the aircraft GPU or a generator; water comes from the handling agent's truck or, for a rinseless wash, from our own tanks.

The photographic report is part of the deliverable. We shoot the aircraft on arrival in six angles: nose three-quarter, tail three-quarter, both profiles, belly and top-down if a ladder or drone is permitted. Close-ups document paint defects, streaking on the cheat line, corrosion on brightwork, stains in the cabin. After the detail we repeat the same angles in the same light, then compile the images into a PDF with our checklist and the date-stamped tech-log entry. Many pre-buy inspectors ask for this file; it proves the aircraft was detailed to a documented standard and gives the buyer confidence that what they see in the cabin photograph is what they will find on the ramp.

When should an operator schedule a complete detail between legs?

Twice a year is the pattern we see: once in early spring to remove winter de-icing residue and prepare the aircraft for the charter season, once in late autumn before a pre-buy inspection or before the aircraft is parked for maintenance. If you are selling, schedule the detail after the C-check but before the broker photographs the interior; buyers form an opinion in the first thirty seconds, and a cabin that smells clean and photographs bright shortens time-to-sale.

For an AOG or a tight delivery window, we can compress the schedule—exterior one day, interior the next—but paint correction works best when the polish has time to cure overnight. Let us know your next three legs and any PPR constraints; we will propose a window that keeps the aircraft available and gives you a result that holds up under the buyer's torch.
