The Cessna 182 Skylane and the Piper Archer (PA-28-181) are both popular single-engine aircraft, widely used for personal travel and flight training. While both are fixed-gear, all-metal designs, their distinct characteristics lead to differences in inspection focus, common corrosion areas, and overall ownership costs. Understanding these nuances is crucial for prospective owners, especially when considering factors like local maintenance availability and labor rates, such as in Lipa City, Calabarzon, Philippines.
INSPECTION FOCUS AND ANNUAL COSTS
Cessna 182 Skylane:
- Inspection Focus: The high-wing design means the wing structure, especially the spar carry-through and wing attach points in the cabin ceiling, are critical areas for inspection. The robust landing gear and firewall area also receive close scrutiny due to the aircraft’s typically higher useful load and potential for harder landings over its service life. The propeller (often a constant-speed unit) adds another layer of inspection beyond a fixed-pitch prop.
- Typical Annual Cost: A standard annual inspection for a Cessna 182, assuming no major discrepancies, can range from $1,500 to $3,000 USD in the US. However, this is for the inspection itself. When factoring in routine maintenance, oil changes, minor repairs, and labor, the annual operating cost for maintenance and repairs is often cited as $2,000 to $5,000 annually, with major overhauls (engine, propeller) being additional, larger expenses. The hourly rate for an aircraft mechanic in the Philippines, for example, averages around ₱35,000 to ₱45,000 per month (approx. $595 – $765 USD), translating to a lower hourly labor rate compared to Western countries, which can influence overall costs.
Piper Archer (PA-28-181):
- Inspection Focus: The low-wing design means the wing spars and skin on the underside of the wing, as well as the main gear attachment points, are key areas. The Piper Cherokee series (of which the Archer is a part) is known for its “wet wing” fuel tanks, making thorough inspection of the fuel tank sealant for leaks a critical part of the annual.
- Typical Annual Cost: A standard annual inspection for a Piper Archer is often comparable to or slightly less than a 172. Estimates place a typical Piper Cherokee/Archer annual at around $2,300 USD. Similar to the 182, this is the baseline, and actual costs will vary based on findings. European estimates show annual inspection costs around $700 USD, with additional maintenance labor and parts contributing to a direct operating cost per hour of $82.57 USD.
Conclusion on Inspections: Both aircraft require diligent annual inspections. The Cessna 182 might have slightly higher baseline annual costs due to its larger engine and constant-speed propeller, but both are susceptible to cost escalation based on wear and tear.
CORROSION: WHERE THEY DIFFER
Both are all-metal aircraft and thus susceptible to corrosion, but common problem areas can differ due to design.
Cessna 182 Skylane:
- Common Corrosion Areas:
- Upper Cabin/Wing Root: As a high-wing aircraft, moisture vapor tends to rise, making the upper cabin skins, wing attach points, and spar carry-throughs susceptible.
- Under Floorboards: Moisture, dirt, and trapped insulation can lead to corrosion on the belly skins. Cessna used lead vinyl sound damping panels that can trap moisture and cause corrosion underneath.
- Lift Strut Attach Points: The lower lift strut attach points on the fuselage, especially where water can collect.
- Empennage/Tailcone: Hidden areas in the tail, especially if water gets past seals.
- Magnesium Components (Older Models): Some older Cessnas used magnesium for parts like wheels or control surfaces, which corrodes aggressively once started. (Less common on modern 182s).
- Fuel Tanks (Bladder vs. Wet Wing): Earlier 182s used rubber fuel bladders. While bladders prevent airframe corrosion within the tank, they can crack and leak with age, requiring costly replacement. Later 182s (and current production) use “wet wings” (integral tanks), which means the wing structure itself forms the tank. If wet wings develop leaks due to sealant degradation (a common issue in aging aircraft), repair can involve extensive and complex resealing, potentially leading to corrosion of the wing structure if neglected.
Piper Archer (PA-28-181):
- Common Corrosion Areas:
- Lower Cabin Areas: Cherokees, including the Archer, tend to corrode in the lower cabin areas, often due to leaking windows and permanently glued-in carpets and insulation. Water can get trapped between the carpet/insulation and the unchromated bare aluminum floor.
- Belly Skin: Accumulation of dirt, oil residue, and industrial pollutants, especially in the belly, can lead to surface and pitting corrosion.
- Wing Spars: While robust, internal wing spar surfaces in contact with dissimilar metals (like steel attachment plates) are susceptible to galvanic corrosion, especially if moisture infiltrates.
- Aft Spar Attachment: Piper Service Bulletin 1413 specifically addresses inspections and potential rework for corrosion and oversized holes at the aft spar attachment on PA-28-181 (and other PA-28/32 models).
- Fuel Tanks (“Wet Wing”): The Archer utilizes “wet wings” for its fuel tanks. Leaks from deteriorating sealant are a very common and significant corrosion driver and repair item for the Piper Cherokee series. Resealing these tanks is a labor-intensive and expensive process, often adding substantial shop time and cost to an annual if not addressed.
Conclusion on Corrosion: Both are susceptible. The Cessna 182’s corrosion issues often stem from moisture trapped by insulation and specific structural areas, and bladder leaks for older models. The Piper Archer is particularly known for lower cabin corrosion due to window leaks and wet wing fuel tank leaks, which are a frequent and costly repair that can lead to significant downtime.
COSTS: A GENERAL COMPARISON
- Purchase Price: Varies wildly by year, condition, and avionics. Generally, a modern, well-equipped Cessna 182 Skylane might command a higher price than a similarly aged Piper Archer due to its higher useful load and performance.
- Fuel Burn: The Cessna 182, with its larger engine, typically burns more fuel per hour (12-15 GPH) than the Piper Archer (around 9-10 GPH), leading to higher direct operating costs.
- Maintenance & Repairs:
- Routine: Annual inspections (as discussed above) are comparable, with the 182 being slightly higher.
- Engine Overhaul: The 182’s larger Continental O-470 or Lycoming IO-540 engine will have a higher overhaul cost (typically $40,000 – $70,000+ USD) compared to the Archer’s Lycoming O-360 (typically $30,000 – $50,000+ USD).
- Specific Major Repairs: Fuel tank reseals for the Piper Archer can be a major expense, potentially running into many thousands of dollars and requiring significant shop time. For the Cessna 182, major corrosion remediation or potential nose gear/firewall repairs (in older models with hard landing history) can be equally costly.
- Parts Availability (Lipa City, Calabarzon, Philippines): Both aircraft are widely used globally. Major distributors (like Textron Aviation for Cessna and Piper’s global dealer network) can ship parts. Companies like PhilJets in the Philippines explicitly offer spare parts sourcing for various aircraft through their networks. Asian Aerospace also keeps a well-stocked inventory of aircraft parts. Due to the sheer number of 172s and Cherokees, the aftermarket for both is robust, making it generally easier to source parts than for less common types.
Overall Cost Summary: While the Cessna 182 has higher direct operating costs due to fuel burn and engine overhaul, the Piper Archer can face significant, recurrent expenses if its wet wing fuel tanks leak. Both are reliable, but require diligent maintenance to prevent cost escalations from corrosion.
