Piper Turbo Saratoga (PA-32R-301T, 1980-2009)

The PA-32R-301T is a Saratoga SP with a turbocharger: the same tapered wing, the same 3,600 lb gross weight, the same 102 usable gallons, the same six/seven-place cabin and retractable gear, with a Lycoming TIO-540 in front instead of the normally aspirated IO-540.

What that buys is altitude. A normally aspirated Saratoga is running out of ideas in the low teens; a Turbo Saratoga holds full rated power to 16,000 ft and will cruise in the high teens with oxygen aboard, which is where the weather usually is not. Against a Cessna T210 or a turbocharged Bonanza it gives away some speed and wins on cabin.

Oxygen is the thing to check. The certificate treats supplemental oxygen as an option — "Compliance with FAR 23.1441 … will be shown with optional supplemental oxygen" — so a factory-installed system is not a given on an airplane whose entire case rests on flying above 12,500 ft. Whether the airframe has a built-in bottle, and whether it is in test, is a real pre-buy question and not a detail.

Every row is from TCDS A3SO. The frontmatter describes the Turbo Saratoga SP.

The old page's variant list said "Turbo Saratoga SP (1980-1989)" and dated the Saratoga II TC to 1997-2009. Section IX's serial range ends at 32R-8629008 plus a small 3229… block, which encodes 1986 in Piper's format, so 1989 is not supported by the certificate. Section XII's 1997 approval is correct.

Read this section as an indication, not as book numbers. Nothing in it is sourced, and one figure deserves a specific warning.

service_ceiling_ft: 20000 is not a certificate figure. A3SO states the engine's rated altitude — 16,000 ft for the TIO-540-S1AD, 12,000 ft for the AH1A — which is a powerplant limit, not a service ceiling. The two are different quantities: rated altitude is where the turbocharger can no longer hold sea-level manifold pressure; service ceiling is where the airframe can no longer climb at 100 fpm. The 20,000 ft on this page comes from the generation pass and has not been checked against a handbook. It is left in place because removing it would leave the field blank, but do not plan on it.

The certificated limits are sourced:

They are identical to the normally aspirated Saratoga SP's, which is what you would expect: same airframe, same wing, same gross weight. The turbo changes what the engine can do, not what the airframe may do. A turbocharged airplane that will happily make cruise power in the high teens is exactly the airplane most likely to exceed Vne in a descent, because true airspeed and indicated airspeed diverge sharply up there — the 197 knot limit is indicated, and the number on the glass is what counts.

Installed power. The certificate rates the S1AD at 300 hp for a five-minute takeoff at 2,700 rpm and 36.0" Hg, and limits maximum continuous to 294 hp at 2,575 rpm on the standard two-blade propeller. Airplanes with the optional three-blade Hartzell carry no continuous derate. horsepower: 300 stores the takeoff rating, per house convention.

Built on the frontmatter's 2,100 lb empty weight and 1,500 lb useful load, both unsourced generation-pass figures — weigh the actual airplane. Fuel is at 6.0 lb/gal, the density the certificate's own NOTE 1 arithmetic implies (107 − 102 = 5 gal against 30.0 lb).

Full tanks and six adults is not a flight this airplane can make, and neither can the normally aspirated Saratoga SP. Four adults, full fuel and a couple of hundred pounds of bags is the real mission, and at that loading it is very good indeed.

Add oxygen to the payload. A built-in system and full bottles are weight, and so is the requirement to carry them — a Turbo Saratoga flown at its best altitudes is not flying at its best payload.

• Flight Training (1/10): No.
• Backcountry (1/10): Retractable gear, low wing, and an engine that does not want to be shock-cooled on a short final into a strip. No.
• Business Travel (10/10): Six seats, a big cabin, and the altitude to go over most of the weather. This is the airplane's case.
• Aerobatics (1/10): Normal category. NOTE 2's placard: "NO ACROBATIC MANEUVERS, INCLUDING SPINS, APPROVED."
• Cross-Country (10/10): 102 usable gallons and turbocharged cruise in the teens. Few piston singles combine this range with this cabin.
• Cargo Hauling (8/10): Good useful load, but the retractable gear and the turbo maintenance make it an expensive freighter.
• Local Fun (5/10): Expensive, and the engine prefers long legs to circuits.
• Surveying (5/10): Carries a payload; low wing blocks the view down.

The certificate records both factory glass options as additional installation-specific certification bases: the Avidyne Entegra system with a Mid-Continent 4300-411 electric attitude indicator on S/N 3257339 and up (Report VB-1885), and the Garmin G1000 on S/N 3257447, 3257455 and up (Report VB-1965). If a listing claims factory glass on an earlier serial, ask which STC it went in under.

A per-cylinder engine monitor is not optional equipment on a turbocharged 540. Cylinder head temperature history is what determines whether this engine reaches TBO, and without a monitor nobody — including the seller — knows what the history is.

Speed brakes matter more here than on the normally aspirated airplane. Descending from 17,000 ft in a slippery retractable with a 132-knot gear limit, without shock-cooling six turbocharged cylinders, is a genuine planning problem.

Parts (good). The TIO-540 is well supported, though turbocharger and exhaust components cost meaningfully more than the normally aspirated equivalents. Gear components are the narrow spot on the airframe side.

Mechanics (common), with a caveat. Any general aviation A&P can work the airframe; a turbocharged 540 and a PA-32R gear system both reward a shop that has seen them before.

Annual cost:

• Routine annual: $4,000-$6,000
• Annual with typical squawks: $6,000-$12,000
• Engine reserve: $32/hour ($58,000 ÷ 1,800 TBO) — note the TIO-540's TBO is shorter than the normally aspirated engine's 2,000 hours, so the hourly reserve is about 25% higher on both counts
• Propeller reserve: $3-$4/hour
• All-in at 100 hours a year: $24,000-$32,000

Expensive items: TIO-540 overhaul $58,000 at national specialty pricing · turbocharger $6,000-$10,000 · turbo exhaust system $4,000-$8,000 · landing gear overhaul $5,000-$10,000 · wing spar work, five figures per wing · three-blade propeller overhaul $4,000-$6,000.

Overhaul pricing is the house figure from reference/engine-overhaul-pricing.md. It was previously $68,000 on this page, which is above the house band for the TIO-540 family.

The price block is not sourced. It is inherited from the generation pass and asking prices are perishable. The band is wide because it spans 29 model years and two different engines, which is calendar and variant spread rather than conflation — the frontmatter describes one airplane and says so.

Value adds: factory glass (Avidyne or G1000) +$30,000-$60,000 · fresh TIO-540 +$25,000-$40,000 · new turbocharger · built-in oxygen with current test · per-cylinder engine monitor with logged history · speed brakes.

Value detractors: high spar time -20-40% · run-out or high-CHT engine -$30,000-$45,000 · gear problems or a gear-up in the logs · no oxygen system on a turbo airplane · legacy avionics.

Airworthiness directives. The PA-28/PA-32 main wing spar directive (AD 2020-26-16, as recorded elsewhere in this catalogue — confirm the applicable list for a specific serial against the FAA's own AD database rather than relying on this page) brought in a factored-service-hours calculation, an eddy-current inspection of the lower spar cap bolt holes at the threshold, and a life limit on unmodified spars.

There is also a turbocharger exhaust directive history on the turbocharged PA-32 models, prompted by in-flight fires traced to failed exhaust couplings near the turbocharger, requiring spot-welded V-band couplings to be replaced with riveted ones. The specific AD number is not recorded here because it could not be verified against the FAA database in this pass — the subject is real and well documented, the number is not something this page should invent. Ask the pre-buy shop for the compliance record.

Common problems:

• TIO-540 cylinders. Turbocharged 540s run hot and cylinder life is a direct function of how they were operated. Borescope all six and read the engine monitor history if there is one. A high-CHT history is a five-figure problem waiting.
• Turbocharger. Shaft play, oil seepage, coking. Replacement $6,000-$10,000.
• Exhaust system. Cracks and coupling failures, more frequent and more serious than on the normally aspirated engine. Budget $4,000-$8,000.
• Wastegate. Verify smooth operation through the full power range; a sticking wastegate is an overboost waiting to happen.
• Cool-down discipline. Three to five minutes at idle before shutdown. A seller who does not know that is telling you something about the engine.
• Oxygen system. Built-in bottle present? Hydrostatic test current? Masks and plumbing serviceable? An airplane bought for altitude that cannot legally go there is worth less.
• Landing gear system. As on the Saratoga SP: nose gear actuators, main gear trunnions and sidebrace studs, hydraulic leaks and door rigging. Budget $1,000-$3,000 a year.
• Wing spar condition. Factored hours and inspection status in writing.

• Hull: 1.5-2.5% of hull value annually, at the higher end of that for a turbocharged retractable flown in the flight levels. Trent's own binders put a fixed-gear Grumman at 0.91% and a retractable Mooney at 1.67% for a 500-hour instrument-rated pilot and 3.33% at 250 hours. See reference/insurance-costs.md.
• Liability ($1M smooth): $1,000-$1,500/year.
• Pilot requirements: typically 500+ hours total, 50+ retractable, 25+ in type, and an instrument rating in practice rather than in principle — an underwriter looking at a turbocharged six-seater assumes it will be flown in weather. Complex and high-performance endorsements both required.
• Expect a dual-instruction requirement written into the first year's policy for a buyer moving up from a fixed-gear single.
