Aero Boero AB-180

The Aero Boero family is a line of Argentine high-wing, strut-braced light utility aircraft produced by Aero Boero S.A., founded in 1956 by Héctor Boero (with his brother Cesar Boero and Celestine Barale) in Morteros, Córdoba Province. The line began with the two-seat AB-95 (first flight 12 March 1959) and grew through progressively more powerful models culminating in the AB-180 and the single-seat agricultural AB-260AG. Production continued in some form until roughly 2000, when political and economic turmoil in Argentina forced it to a halt; the company has continued providing repair services and spare parts since.

The AB-180 is the 180 hp, three-seat member of the line, built around the same Lycoming O-360-A1A that powers a great many American light aircraft. Its RVR sub-variant is a purpose-built glider tug — the manufacturer's own eligible-propeller table lists a shorter, tow-specific pitch option alongside the normal-category setting, direct evidence the tow role was part of the type design rather than a field modification. Most surviving airframes remain in South America; a small handful exist on FAA rolls under Experimental registration (most plausibly Exhibition — see the certification_basis note above). See Maintenance Ecosystem for notes on orphan-support aircraft.

No cruise speed and no range or endurance figure are published anywhere in the sourced flight manual. Its Section 5 (Performances) table of contents lists only: velocity calibration, stall-vs-bank-angle, takeoff run, climb speed, fuel consumption, and landing distance — confirmed by reading the section itself, not merely by an absent citation. This is consistent with a type built and marketed as a primary trainer and glider tug rather than a cross-country tourer. cruise_speed_ktas and range_nm are left blank rather than filled from a secondary source, per rule 29 — range is explicitly one of the fields that rule forbids filling that way in any case.

Fuel burn (9.5 gph) has no paired airspeed. The manual's Consumo table gives RPM, %HP and fuel flow by altitude (2450 rpm / 65% power / 36.0 L/hr at sea level, stepping down to 2600 rpm / 60% / 33.0 L/hr at 3,000 m) but states no corresponding true airspeed for any row, so it cannot be combined with a cruise speed the way the schema's cruise_percent_bhp / cruise_altitude_ft pairing assumes — those two fields are left blank rather than attached to a speed the source does not give.

Rate of climb (994 fpm) is measured at 780 kg, not the 844 kg max gross weight — the manual's own climb tables use this lighter figure with no explanation given, and it is reported as what the document states rather than adjusted. Interestingly, the manual's flaps-30 climb table shows a marginally BETTER climb (1,024 fpm at 56 mph) than the flaps-0 table (994 fpm at 58 mph) at the same weight — recorded as a real disagreement-with- expectation rather than smoothed away.

Takeoff and landing distances are density-altitude-sensitive by the manual's own tables: takeoff ground roll grows from 85 m at sea level to 115 m at 2,000 m density altitude (+35%), and landing ground roll from 88 m to 121 m (+38%) over the same range — Argentine summer operations at altitude (the Andean foothills, not just Córdoba's plains) will see materially longer distances than the sea-level figures stored above. The manual also states: add 1% of takeoff distance per °C above the table's reference temperatures, and add 10% for a short-grass runway.

Category is Normal, and aerobatics of any kind are explicitly prohibited — the flight manual states outright "TODAS LAS MANIOBRAS ACROBATICAS PROHIBIDAS, INCLUIDO TIRABUZON" (all aerobatic maneuvers prohibited, including spins). Load factor limits are the standard normal-category envelope: +3.8 G / −1.52 G flaps up, +1.9 G flaps down, with negative-G maneuvers of any kind prohibited outright. This is a materially different limitation shape from an aerobatic type (compare Mudry CAP 10B's +6.0/−4.5) and confirms this is, as expected, a Piper Cub-class utility taildragger rather than anything aerobatic.

All variants share large flaps and a low stall speed (43 KIAS clean), giving genuine short-field performance per the sourced takeoff/landing tables above. The wing is strut-braced with a NACA 23012 section at relatively modest aspect ratio.

Corrected this session: fuel capacity was previously stored as 34 gal (uncited) against a sourced 45.2 gal usable, and useful load as 635 lb against a sourced 534 lb (from the manufacturer's own 844 kg max weight and 602 kg type-design empty weight — both figures the flight manual itself attributes to "the aircraft's Type Certificate," i.e. the Argentine one).

At 1,861 lb MTOW, 1,327 lb empty, 534 lb useful load:

• Full fuel (271 lb) + 2 adults (360 lb): no baggage margin (271 + 360 = 631 lb against a 534 lb limit — 97 lb over). Full fuel plus two average adults is NOT within useful load; something has to give.
• 2 adults (360 lb) + baggage (55 lb, the certificated max): 415 lb, leaving 119 lb of fuel — about 20 gal, roughly 2 hours at the sourced 65%-power fuel burn.
• Solo + full fuel (271 lb): 271 lb of the 534 lb limit used, 263 lb remaining for a passenger and/or baggage.
• Solo glider tow: pilot (180 lb) + full fuel (271 lb) = 451 lb, 83 lb margin for tow gear — comfortable.

This is a tighter airplane at full fuel and two adults than the prior, uncited numbers suggested, not a more generous one — worth flagging for the "3-seat" marketing the type carries, since the third seat is realistically a child's or a short-hop-only proposition at anything near full tanks.

• Flight training (7): Well-regarded primary trainer in South America; docile handling, low stall, simple systems, genuine short-field numbers. North American training use limited by parts/mechanic availability. See Flight Training.
• Backcountry (5): Strong short-field numbers and light wing loading suit grass strips, but fixed tricycle gear and modest prop clearance limit rough-field use versus a Husky or Super Cub. See Backcountry / Bush Flying.
• Local fun flying (7): Good visibility, honest handling, cheap to buy if you can find one.
• Business travel (2): No published cruise figure to plan a trip on, and no IFR certification.
• Aerobatics (1): Normal category only; all aerobatic maneuvers including spins are explicitly prohibited by the flight manual.
• Cross-country (3): No range or cruise-speed figure is published by the manufacturer; real-world cross-country use is plausible on 45 gal usable fuel but not quantifiable from primary sources located this session.
• Cargo hauling (2): Small cabin, modest useful load (534 lb).
• Surveying (5): Low-and-slow capability and good visibility suit pipeline/fence patrol where the type is supported.

Glider towing is the AB-180RVR's true specialty and not one of the standard mission axes — it would score 9+ on a dedicated "tow plane" mission, and its type design (a tow-specific propeller pitch option, per the sourced flight manual) reflects that directly.

Aero Boeros left the factory with the minimum VFR panel typical of 1970s–1990s South American club aircraft: single nav/com, transponder, and basic engine gauges. No factory IFR certification exists. North American owners typically install a handheld or portable GPS rather than invest in certified avionics given the airframe's low market value and orphan-support status. See Aircraft Valuation Methodology.

The type is not FAA type-certificated, so the US STC system does not apply to it; US registrations are typically Experimental, which allows modification without an STC but also restricts commercial use. Common field modifications include a tow-release kit (factory-standard on the RVR sourced this session, field-installable on other variants), larger tires for grass operations, and owner-performed engine changes on other members of the family. Brazilian- and Argentine-registered aircraft follow local airworthiness directives, not the US system.

Aero Boero S.A. still exists and continues limited parts and repair support from Morteros, Córdoba, but its own web presence has effectively vanished — aero-boero.com.ar does not resolve from this session, and the manufacturer's own flight manual for this airplane survives only in the Internet Archive. For US operators:

• Engine and propeller: full support — standard Lycoming and Sensenich/McCauley parts (both listed as eligible propellers in the sourced flight manual).
• Airframe parts: must be fabricated, cannibalized, or sourced from Brazil/Argentina on long lead times.
• Landing gear, brakes, wheels: Cleveland/McCauley aftermarket fits most variants.
• Cowling, fairings, transparencies: major problem items — custom fabrication required.

A&P mechanics outside Brazil and Argentina rarely see the type. See Maintenance Ecosystem for orphan-support strategies.

The North American market is tiny — no manufacturer listing page even exists on GlobalPlaneSearch (see the market passage cited above), and typically fewer than a dozen airframes exist on the FAA registry at any time. Not independently re-priced this session; the prior pass's estimates are carried over. Engine condition dominates valuation more than on common types because the airframe itself has little resale premium. See Aircraft Valuation Methodology.

No FAA airworthiness directives apply, since the type is not FAA type-certificated — the Argentine DNA and Brazilian ANAC authorities publish their own equivalent directives, not sourced this session. Common issues reported by operators: wing strut attachment fitting inspection (recurrent), fuel tank sealant replacement on older airframes, elevator hinge and trim cable inspection, and engine mount cracking on high-time trainers.

Pre-buy red flags: corrosion in the steel-tube fuselage structure (especially aircraft operated near coastal Brazil), fabric condition on older airframes, and documentation gaps — logbooks in Spanish or Portuguese are common and may be incomplete by US standards. Engine time is usually the limiting factor; Lycoming cores are standard so overhauls are not exotic.

Hull insurance is difficult to place in the US because underwriters have no actuarial data on the type. Liability-only coverage is readily available; hull-plus-liability typically requires a specialty broker and may need an owner-supplied appraisal. See GA Insurance Underwriting.
