Your annual inspection expires in the next 90 days, or your 100-hour clock is running out on your training fleet. You need a Transport Canada Certified AMO that will give you a firm price, a realistic timeline, and a signed inspection checklist — not a list of surprises after the cowling comes off.

Muskoka Aircraft Maintenance & Modifications Inc. (AMO #41-21) performs annual and 100-hour inspections for Cessna, Piper, and Cirrus aircraft based at Muskoka Airport, Toronto, Barrie, and surrounding Ontario airports. Typical turnaround: 5 days from drop-off. Firm quote provided before any work begins.

What Makes Muskoka Aircraft Different for Annual Inspections

Most AMOs treat annuals as a paperwork exercise. We treat them as a safety opportunity. Here is what that means for your aircraft:

• We find problems before they ground you. In the last 12 months, our inspections identified spar corrosion, cracked exhaust stacks, and worn elevator control cables on aircraft that passed annuals elsewhere. Every finding includes a photo and a repair cost estimate.

• Your aircraft gets a reserved hangar bay. We book a maximum of three annuals per week. Your aircraft stays inside for the full inspection. No rush jobs. No parking on the ramp.

• You get a written squawk report with priorities. Each discrepancy is labeled: Airworthiness Directive (must fix now), Safety Issue (fix before next flight), Recommended (fix at convenience), or Cosmetic. Every item has a dollar amount.

• Transport Canada AMO #41-21 certification. Transport Canada audits our processes, tools, tools, and technician qualifications. See our Transport Canada AMO #41-21 compliance guide for what this certification actually requires.

How We Handle Annual Inspections — The Full Process

We complete annuals in five stages. No mystery. No hidden steps.

Step 1: Logbook review and owner interview (2 hours)

You drop off your aircraft at 1006 Sabre Lane Unit 3, Gravenhurst. We review your logbooks for past AD compliance, open service bulletins, and inspection history. We ask you three questions: What squawks have you noticed? What has been repaired since last annual? What do you want us to pay extra attention to?

Most delays come from missing 337 forms or incomplete logbook entries. We catch these before we touch the aircraft.

Step 2: Engine and systems borescope (3 hours)

We borescope every cylinder on Lycoming, Continental, and Rotax engines. We inspect the accessory case, magnetos, starter, and alternator. For turbocharged engines, the turbocharger wheel and housing get a full inspection. We document cylinder wall condition, valve face deposits, and any signs of detonation or overheating.

Step 3: Airframe disassembly and detailed inspection (6 to 8 hours)

Interior panels, floorboards, inspection covers, control surface hinges, and fairings come off. We specifically inspect:

• Wing spar carry-through and rear spar attach points for corrosion

• Control cable tension, pulleys, and turnbuckles

• Landing gear attach points, pivot bushings, and side braces

• Fuel tank seals, vent lines, and selector valve operation

• Flap and aileron hinge bearings and pushrod ends

The #1 grounding finding in Ontario is wing spar corrosion on Cessna high-wing aircraft. We find it early.

Step 4: AD and service bulletin compliance check (concurrent with Step 3)

We pull the current Airworthiness Directive list for your specific make and model. Each AD is verified — not just marked “complied with at last annual.” If an AD requires repetitive inspections (e.g., spar bolt torque check every 100 hours), we verify the last compliance date and schedule the next due date for your logbook.

Step 5: Reassembly, run-up, and final paperwork (2 to 3 hours)

All panels and fairings go back with torque-sealed fasteners. We run the engine to operating temperature, check for leaks, verify all systems, and perform a full control surface sweep. You receive:

• Signed annual inspection checklist (TCA Form 24-0101)

• Detailed discrepancy report with photos and repair estimates

• AD compliance log update

• Ferry permit if repairs are needed elsewhere

Typical timeline: Drop off Monday morning. Pick up Friday afternoon. Rush service available (3 days) for an additional charge.

Annual Inspection Pricing in Muskoka — What to Expect

Base annual inspection price ranges by aircraft type:

What changes the price from low end to high end:

• Low end: Under 500 hours since new, complete logbooks, owner removes interior panels before drop-off, no known squawks.

• Typical range: 500 to 2,000 hours, minor squawks (sticky mag switch, worn brake disc, one small corrosion spot).

• High end: Over 2,000 hours, missing logbooks requiring AD research, retractable gear, turbocharged engine.

100-hour inspection pricing: $1,600 to $2,000 — typically lower because 100-hours are on high-utilization aircraft (flight schools, charter operators) with recent inspection history and known maintenance patterns.

Common additional items (not included in base price):

• Compass swing and certification: $180

• Pitot-static system check (required for IFR): $350

• ELT battery replacement: $120 plus battery cost

• Oil change with oil filter analysis: $95

• Wheel bearing repack and brake inspection: $150 per wheel

We provide a firm written quote before starting. If we find a discrepancy during inspection, you approve the repair cost in writing before we proceed. No surprise bills. No “while we were in there” charges.

For fleet operators, see our fleet maintenance support page for volume pricing on multiple annuals.

The One Question Most Owners Ask Before Booking

“Can you guarantee my annual will be done before my insurance renewal / flight school schedule / cross-country trip?”

Yes — with one clear condition.

If you drop off on Monday and no major discrepancies are found (no structural corrosion requiring metal work, no engine teardown, no parts on backorder), your aircraft is ready for pick-up by Friday of the same week. We book only three annuals per week specifically to protect this timeline.

If a major discrepancy is found, you have three options:

1. Approve the repair — we add time based on parts availability and repair complexity (typically 5 to 10 additional days). You get daily updates.

2. Defer the repair — we sign off the annual if the discrepancy is not an airworthiness issue. You fly with a written repair plan and deferred item list.

3. Ferry permit to your preferred shop — we provide documentation to move the aircraft (unpressurized, day VFR only) to another facility for repairs.

We have never missed a promised pick-up date for an annual with no major discrepancies. Call 705-687-3300 and ask for our current lead time before booking.

Questions Muskoka Aircraft Owners Ask About Annual Inspections

How far in advance should I book my annual?

Book 6 to 8 weeks before your expiration date. Spring and fall (pre-season and post-season) book out 10 to 12 weeks. We maintain a waitlist and will call you if a slot opens earlier.

Do you offer owner-assisted annuals?

Yes, for owners who want to learn and save on labor. You remove interior panels and inspection covers under our supervision. You save $300 to $500 depending on aircraft type. Call to schedule — owner-assisted annuals take 6 days instead of 5.

What happens if you find corrosion?

We document every corrosion location with photos and depth measurements. Surface corrosion gets treated and primed. Intergranular corrosion or exfoliation corrosion requires structural repair or component replacement. We provide a repair plan with options and costs. Most corrosion findings add 1 to 3 days to the inspection.

Do you work on floatplanes?

Yes. We inspect floatplanes on wheels (in our hangar) or on floats (ramp inspection with special approval). Floatplane annuals require additional inspection of float attach points, water rudder cables, and corrosion on lower fuselage. Call ahead — floatplane annuals need an extra day.

What paperwork do I need to bring?

Current certificate of registration, certificate of airworthiness, maintenance release (if applicable), and all logbooks (airframe, engine, propeller, and avionics if they affect airworthiness). Missing logbooks require AD research — add $250 and 1 day to the inspection.
