Minimize Downtime with ATC’s 5-Week Turnaround
ENGINE OVERHAUL: FAST TURN AROUND. NO SURPRISES.
Engine-In to Engine-Out in About 5 Weeks.
While most shops are quoting 8–10 weeks, ATC typically completes piston engine overhauls in about five — because we’ve structured our shop specifically around efficient, high-quality turnarounds.
Note: Turnaround time refers to the overhaul itself. Engine removal and reinstallation are separate services available through Brant Aero and are not included in this timeframe.
~5 Wks: TYPICAL TURNAROUND
Fast: ESTIMATE RESPONSE
8–10 Wks: INDUSTRY AVERAGE
WHY TURNAROUND MATTERS
Every week on the ground is a week you’re not flying.
When your engine needs work, the clock starts immediately. Missed flying seasons, cancelled trips, and idle aircraft add up fast. That’s why ATC has structured its shop to move piston engine overhauls through efficiently — without sacrificing the quality of the work.
Reach out and we’ll get back to you quickly with a budgetary estimate — so you understand the financial picture before committing to anything. From there, we work with you to find the right slot and the right scope.
What a Typical 5-Week Overhaul Looks Like
Engine-in to engine-out. Removal and reinstallation are separate — see below.
Intake, Teardown & Inspection
Engine received, fully disassembled, and every component measured and assessed. You receive a teardown report and confirmed scope before anything proceeds.
Parts Review & Ordering
Required parts identified and ordered without delay. ATC stocks common components so most orders move quickly, keeping your slot on schedule.
Machine Work & Case Preparation
Crankshaft work, cylinder servicing, and case preparation completed. Precision work done right — not rushed.
Assembly
Engine assembled to overhaul manual tolerances. New seals, gaskets, and hardware throughout — no reused consumables.
Test Run, Final Inspection & Release
Engine run-in on the test stand, final inspection completed, and paperwork signed off. Ready for pickup, shipping, or reinstallation coordination.
Please note: The ~5-week timeframe covers the overhaul of the engine core only. If your aircraft requires engine removal and reinstallation, that work is performed separately by Brant Aero and will add time to your overall project. We’re happy to help coordinate the full scope — just let us know at the outset.
FULL – SERVICE CONVENIENCE
Need removal and reinstall too? Brant Aero has you covered.
ATC and Brant Aero are part of the same company. If your aircraft also requires engine removal, reinstallation, and return-to-service, those services can be completed by Brant Aero as a separate coordinated scope — additional time and cost apply. No juggling multiple shops or tracking down different contacts. One company, one conversation.
The best time to reach out is before you’re grounded. Our schedule fills, and owners who contact us early have the most flexibility on timing. Get in touch and we’ll respond quickly with a budgetary number so you can plan with confidence.

The small print – please read me!
All turnaround times are estimates based on typical scope and are subject to change depending on findings at teardown, parts availability, and the extent of work required. ATC will communicate promptly if anything affects your expected timeline. Budgetary estimates provided prior to teardown are preliminary in nature and will be confirmed in writing following physical inspection and teardown findings. ATC will not proceed with work beyond the agreed scope without owner authorization. Engine removal, reinstallation, and return-to-service are services performed separately by Brant Aero under a separate scope of work and agreement; ATC’s turnaround timeframe covers the engine overhaul only and does not include time associated with those services. Any guidance provided by ATC prior to teardown is based on information available at the time and is intended as general guidance only; all formal recommendations are made in writing following a physical inspection. A zero-time overhaul may positively impact aircraft resale value; actual impact will depend on aircraft type, market conditions, and buyer expectations — ATC does not provide aircraft valuation advice. Regulatory applicability of overhaul standards depends on jurisdiction, aircraft registration, and the standards to which the overhaul is performed; owners should confirm requirements with their AME or the relevant aviation authority. Nothing in this communication constitutes a warranty, guarantee, or formal recommendation
