Piper Dakota (1979-1994)

The Piper PA-28-235/236 lineage represents the biggest engine ever installed in the PA-28 Cherokee family, producing 235 horsepower from various Lycoming O-540 variants across a 30-year production run (1964-1994). The series began as the PA-28-235 Cherokee 235 in 1964, evolved through the Charger and Pathfinder marketing names in the 1970s, and culminated in the PA-28-236 Dakota from 1979 to 1994 -- the most refined version, featuring a tapered semi-tapered wing and a stretched fuselage.

The Dakota's appeal is straightforward: it is a fixed-gear, four-seat airplane with genuine load-hauling capability and respectable cruise performance. With a useful load of nearly 1,400 lbs and 72 gallons of fuel, the Dakota can carry four adults with full bags and still have meaningful range. It is often compared to the Cessna 182 Skylane -- both serve the same "family hauler with range" mission, though the Dakota does it from a low-wing platform with Cherokee handling qualities. The 235 HP O-540 engine makes the Dakota a high-performance aircraft under FAA definitions, requiring a high-performance endorsement to fly.

Approximately 3,400 PA-28-235 and PA-28-236 aircraft were built across all variants. The Dakota (PA-28-236) alone accounts for roughly 1,600 of those. Today, the Dakota is well-regarded as a practical, honest airplane that does not command the premium pricing of the Cessna 182, making it a value proposition for load-conscious buyers.

The PA-28-236 Dakota is the clear pick of the lineup. The tapered wing improved handling and reduced drag, the new O-540-J3A5D engine offered better fuel efficiency and reduced vibration, and the 100-lb gross weight increase to 3,000 lbs translated directly into useful load. Earlier PA-28-235 models are perfectly serviceable but typically sell for less due to the older Hershey bar wing and higher fuel consumption.

The Dakota cruises at 135-143 KTAS at 75% power depending on altitude and configuration. At 65% power, expect 128-132 KTAS on about 12.5 GPH -- the sweet spot for cross-country efficiency. The 14 GPH figure at 75% is the primary compromise: this is not a fuel-efficient airplane by modern standards, but it moves four people and their gear at a respectable pace.

Rate of climb at 1,110 fpm is strong for the class and noticeably better than a standard Cherokee 180 or Archer. The 235 HP engine gives the Dakota authority during takeoff and climb that lighter PA-28 variants lack, particularly at higher density altitudes. Service ceiling of 17,500 feet is adequate for mountain operations in the western United States, though the normally-aspirated engine loses efficiency above 8,000-10,000 feet.

Takeoff ground roll of 886 feet and landing roll of 640 feet are good numbers for a 3,000-lb airplane. The Dakota is comfortable operating from 3,000-foot runways even at gross weight in warm conditions. Short-field performance is not its primary mission, but it is more capable than its size suggests.

The earlier PA-28-235 models with tip tanks carried up to 84 gallons of fuel, giving them exceptional range but at the cost of slightly higher drag from the tip tanks themselves. The Dakota's 72-gallon integral wing tanks are aerodynamically cleaner and provide 650+ nm of range at economy cruise.

The Dakota's nearly 1,400-lb useful load is its defining advantage within the PA-28 family. With full fuel (432 lbs), there remains 960 lbs for occupants and baggage -- enough for four 200-lb adults with 40 lbs of bags each. This is a genuine four-seat-with-bags airplane, not just on paper but in practice. The 72-gallon fuel capacity provides 4.5+ hours of endurance at 75% power or over 5 hours at economy cruise, making 500+ nm legs routine with comfortable reserves. For the two-occupant cross-country mission, the Dakota's range and payload flexibility are exceptional: full fuel, two adults, and several hundred pounds of gear with range to spare.

• Flight Training (4): The Dakota's 235 HP and high-performance endorsement requirement make it unsuitable for primary training. It sees occasional use for high-performance endorsement training, but the operating cost is prohibitive for most schools.
• Backcountry (3): Fixed gear is a plus for rough strips, but the Dakota is heavy for backcountry work. Prop clearance on the low wing is a concern on unimproved surfaces. Better options exist.
• Business Travel (6): Solid regional business machine. Four seats, good range, respectable speed. Falls short of turbocharged or retractable alternatives for longer trips, but excels in the 200-400 nm radius.
• Aerobatics (1): Not certified for aerobatic flight.
• Cross-Country (8): This is the Dakota's core mission. With 72 gallons of fuel, 143-knot cruise, and the ability to carry four adults with baggage, the Dakota is a genuine cross-country machine. IFR capable with appropriate avionics. Range of 650+ nm means many trips are nonstop.
• Cargo Hauling (7): The nearly 1,400-lb useful load is the Dakota's strongest selling point relative to the PA-28 family. With two occupants, there is substantial capacity for cargo. The flat cargo area behind the rear seats is practical and accessible.
• Local Fun (5): Cherokee handling is pleasant but not thrilling. The Dakota is a bit heavy and fuel-hungry for pure recreational flying. It shines when you are going somewhere with stuff.
• Surveying (4): Low wing reduces ground visibility compared to high-wing alternatives. Not an ideal survey platform.

Most surviving Dakotas are owner-flown aircraft (not ex-trainers), so panels tend to be reasonably well-maintained. Common configurations by price tier:

• Budget ($90K-$120K): Original steam gauges, older King or Narco radios, possibly a basic GPS like a KLN-89B or GNS 430 non-WAAS. Functional for VFR, marginal for regular IFR.
• Mid-range ($120K-$175K): Garmin GNS 430W or GTN 650, basic autopilot (Century or KAP 140), ADS-B compliant. Capable IFR platform for cross-country work.
• Premium ($175K-$240K): Garmin GTN 750Xi or G500 TXi, GFC 500 autopilot, full ADS-B In/Out, engine monitor. These are the well-loved, continuously upgraded Dakotas that justify their price premium.

The Dakota shares the standard PA-28 panel layout, so all Cherokee/Archer/Arrow avionics STCs and mounting kits apply. See Avionics Pricing Reference for current equipment and installation costs.

The Dakota does not have the same depth of engine upgrade STCs as smaller PA-28 variants -- the O-540 at 235 HP is already the correct engine for this airframe. Speed modifications are the most common upgrades, as they directly improve the cross-country mission.

• Parts availability: Excellent. The PA-28 family is one of the most widely supported aircraft in general aviation. Structural parts, cowling components, and interior items are readily available from both Piper and aftermarket suppliers. The O-540 engine parts ecosystem is extensive.
• Mechanic familiarity: Common. Nearly every A&P has worked on PA-28 Cherokees. The Dakota's O-540 engine is well-understood across the maintenance community.
• Annual inspection cost: $2,000-$3,500 depending on findings. The fixed-gear configuration keeps annual costs lower than retractable PA-28 variants.
• Engine overhaul: $44,000–$60,000 for a field overhaul of the O-540-J3A5D. Factory reman available from Lycoming at approximately $58,000+ core. The six-cylinder O-540 is a proven, reliable engine with a 2,000-hour TBO.
• 100-hour inspections: Comparable to annual cost for flight school operations, though most Dakotas are owner-flown and only require annual inspections.

See Maintenance Ecosystem for general maintenance cost context.

The Dakota market splits cleanly between early PA-28-235 models and the later PA-28-236 Dakota. The Dakota consistently commands a premium due to its tapered wing, higher gross weight, and improved engine.

Key price drivers:

• Wing type: Tapered-wing PA-28-236 Dakotas typically sell for $30,000-$50,000 more than comparable-condition PA-28-235 Hershey bar wing models.
• Engine time: The O-540 overhaul at $44,000–$60,000 is a significant cost. Fresh overhauls command proportional premiums. See Aircraft Valuation Methodology.
• Avionics: Modern avionics suites can add $30,000-$60,000 to value. A Dakota with a GTN 750 and GFC 500 is a substantially different airplane than one with King KX-155s.
• Corrosion: Coastal-based Dakotas need careful corrosion inspection. Wing spar and carry-through structure are critical areas.

Critical ADs

• Wing spar AD (2020-25690): A significant AD requiring inspection of wing spar for corrosion. Notably, the PA-28-236 Dakota is excluded from the 2020 wing spar AD that affected many other PA-28 models, but the earlier PA-28-235 models ARE included. Buyers of PA-28-235 variants should confirm compliance.
• Fuel selector placard AD: Requires inspection of fuel tank selector cover to verify left/right placards are properly positioned. A quality control issue at the factory resulted in some covers being installed with reversed placards, which could lead to fuel management errors and engine fuel starvation.
• Lycoming O-540 ADs: Standard Lycoming service bulletins and ADs apply, including crankshaft inspections and cylinder through-bolt torque checks. Consult the Piper Owner Society AD list for the current complete set.

Chronic Problems

• Nose gear shimmy: A classic Cherokee complaint. Nose wheel shimmy dampeners wear and need periodic replacement. Not dangerous but annoying and can cause structural fatigue in the nose gear assembly over time.
• Exhaust system cracks: The O-540 exhaust is subject to cracking, particularly at weld joints. Regular inspection is essential for carbon monoxide safety.
• Fuel tank leaks: The integral wing fuel tanks on the PA-28-236 can develop leaks at seams, particularly in older airframes. Reseal costs $3,000-$6,000 per tank.
• Stabilator trim barrel wear: The threaded trim barrel can develop play over time, leading to sloppy trim response. Replacement is a periodic maintenance item.
• Magneto timing: The O-540 magnetos require regular attention to maintain proper timing and smooth operation.

The Dakota falls into the fixed-gear high-performance category for insurance purposes. Despite having 235 HP and requiring a high-performance endorsement, the fixed landing gear keeps insurance rates substantially lower than retractable alternatives like the Piper Arrow or Cessna 172RG.

For a private pilot with 300+ hours and a high-performance endorsement, expect annual hull and liability premiums of $1,500-$2,200 on a $150,000 hull value. Pilots with instrument ratings and significant cross-country time will find the best rates. See GA Insurance Underwriting for category details.

The Dakota's fixed-gear simplicity is an insurance advantage. Gear-up landing risk is eliminated, which is the single largest claim category for retractable singles. Underwriters view the Dakota favorably as a result, and experienced Cherokee pilots transitioning to the Dakota face minimal insurance surcharges.
