These figures are typical for the model, not a specification for any individual aircraft. Real-world numbers vary with year, installed equipment, weight, modifications and engine condition — often by more than you would expect. Use them to compare types, and confirm anything you would act on against the Pilot's Operating Handbook for that specific airframe and a prebuy inspection.

Annual all-in
~$22k/yr
All-in at ~100 flying hours a year, using the midpoint of each range — the same figures broken out under “Cost to own” below. Your number will differ, and mostly for two reasons. Experience sets your insurance: a 2,000-hour pilot with recent training pays 30–40% less than a 200-hour owner, and student owners pay 20–40% more — on the same aircraft that is often a doubling. Location sets your hangar: a T-hangar runs $200–400 a month in the Midwest against $400–1,500 in a coastal metro, and an outside tie-down is less again. Engine reserves move too — a local shop reusing your serviceable cylinders can come in 30–50% under the national specialty-shop pricing we quote, though you trade the warranty and turnaround that comes with it. Reserves are money set aside toward a future overhaul, not a bill this year, and the annual inspection figure is the shop’s labor to look — whatever they find is separate.
Cost to own — estimate

Fuel, engine reserve and wear only. Insurance, hangar and the annual are already paid whether you make the trip or not, so they are not charged here.
Estimate, not a quote. Where a line shows a range, the total, per-hour and per-mile figures use its midpoint— insurance moves most with your experience and time in type, hangar with where you base the aircraft, so your own number could sit at either end. Annual inspection is the shop's labor to open and inspect — what they find is the maintenance line, which covers oil changes, plugs, tires, brakes, hoses, lights, a battery and vacuum pump amortised over their life, and the unscheduled squawks that are the largest and least predictable part of it. Reserves are sinking funds toward an overhaul, not a bill you pay this year — and note that a propeller is due on hours or calendar time, typically six years, so flying less does not put it off forever.

Strengths
- First year of tubular gear — significantly more stable ground handling than earlier 172s
- Wider 12-inch gear track reduces landing oscillation and improves crosswind performance
- Better landing energy absorption and crash protection vs. flat-spring gear
- Proven Lycoming O-320-E2D engine, 121 KTAS cruise, simple and reliable
Weaknesses
- Tubular gear legs require straightness inspection — buckling from hard landings is expensive
- Original 1971–1972 fiberglass gear fairings commonly crack or crack-prone
- First-year production model — verify all service bulletins addressed
- Slightly reduced useful load (~895 lbs) due to heavier gear and fairings vs. 172K
Overview
The 1971-1972 Cessna 172L's defining change is the switch from flat-spring steel main gear to tubular steel main gear, accompanied by a 12-inch wider main gear track. This is one of the most consequential ergonomic changes in 172 history -- the new gear is more stable on the ground (less prone to gear leg flex during taxi), absorbs landing loads better, and has lower drag. The wider track also reduced the tendency for landing-gear oscillation ("wallowing") on rough surfaces. Roughly 2,200 172L examples were produced across 1971 and 1972.
The 172L's tubular gear became standard on every 172 from 1971 forward and is universally retrofittable to earlier 172s via STC. Fairings were also added to the gear legs to recover the aerodynamic drag of the new larger-diameter tubes.
Tubular vs Flat-Spring Gear
The shift to tubular main gear introduced several practical improvements:
| Factor | Flat Spring (pre-1971) | Tubular (1971 onward) |
|---|---|---|
| Track width | Original | +12" wider |
| Ground handling | More flex, "wobbly" | Stiffer, more stable |
| Landing energy absorption | Spring deflection | Tube compression |
| Drag (with fairings) | Lower (no fairings needed) | Slightly higher (requires fairings) |
| Maintenance | Spring crack inspection | Tube straightness inspection |
| Crash energy absorption | Marginal | Improved |
| Cosmetic | Period-correct vintage look | Modern look |
For pilots, the tubular gear feels noticeably more "planted" on the ground -- a particularly welcome change in crosswind landings. The wider track also improves taxi stability on uneven surfaces (gravel, grass).
Variants & History
| Feature | 172K (1969-1970) | 172L (1971-1972) | 172M (1973-1976) |
|---|---|---|---|
| Main gear | Flat spring steel | Tubular steel (new) | Tubular steel |
| Gear track | Original width | +12" wider (new) | +12" wider |
| Gear leg fairings | None | Required (new) | Standard |
| Wing | Original | Original | Camber-Lift drooped leading edge (new) |
| Baggage door | Optional | Optional | Standard (new) |
| Engine | Lycoming O-320-E2D | Lycoming O-320-E2D | Lycoming O-320-E2D |
Performance
121 KTAS cruise, 645 FPM climb, 8.0 GPH. Performance virtually identical to 172K. Empty weight increases ~10 lbs vs 172K due to the heavier tubular gear and required fairings, reducing useful load to ~895 lbs. The drag of the larger gear tubes is offset by the new fairings, keeping cruise speed unchanged.

Valuation Factors
| Condition | Price Range |
|---|---|
| Project / needs engine | $30,000-$42,000 |
| Flying but tired | $42,000-$60,000 |
| Well-maintained | $54,000-$74,000 |
| Restored / upgraded | $72,000-$92,000 |
The 172L typically prices $2,000-$5,000 above a 172K in equivalent condition due to the tubular gear and (for buyers who care) wider track. 172L pricing is essentially identical to 172M except in restored condition where the 172M's Camber-Lift wing commands a slight additional premium.

ADs & Common Problems
Universal Cessna 172 pre-buy concerns apply. 172L-specific:
- Tubular gear inspection: Verify straightness of both main gear legs. Tube buckling from hard landings or curb strikes is a costly repair (~$3,000-$5,000 per leg). Look for paint cracking near attach points.
- Gear leg fairing condition: Original 1971-1972 fiberglass fairings often have cracks or damage. Replacements available ($150-$300 per pair).
- First-year tubular gear: The 1971 model year is the first year of the tubular gear; verify any service bulletins addressing initial-production issues have been complied with.
- Wheel pant fit: The wider track required revised wheel pants. If the airplane has aftermarket pants, verify proper fit and structural integrity.
