Which Airplanes This Book Serves

The Piper PA-32-301FT 6X and PA-32-301XTC 6XT Airplane Maintenance Manual 2003-2008 is the Piper Aircraft, Inc. maintenance publication prepared to GAMA Specification No. 2 chapter numbering. Effectivity is limited to PA-32-301FT serial numbers 3232001 thru 3232074 and PA-32-301XTC serial numbers 3255001 thru 3255051. Model-year tables in the introduction list 6X production from 2003 through 2008 and 6XT production from 2003 through 2006 as a general reference only; always match the airplane data plate to those serial ranges before using a procedure.

The manual itself is the Instructions for Continued Airworthiness required by FAR Part 23, Appendix G. Chapter 4 holds the FAA-approved Airworthiness Limitations section (4-00-00). Chapter 5 holds the inspection program (5-20-00) plus time limits, special inspections, and unscheduled checks. Instructions for Continued Airworthiness belonging to non-Piper approved STC installations are not in this book; any airplane modified that way must also be inspected to the STC holder’s ICA.

Powerplant, Propeller, Fuel, and Gear Particulars

Chart 1 in Chapter 6 records the hardware these airframes were built around. The PA-32-301FT (6X) uses a Lycoming IO-540-K1G5 rated 300 HP at sea level at 2700 RPM. The PA-32-301XTC (6XT) uses a turbocharged Lycoming TIO-540-AH1A rated 300 HP to 12,000 ft at 2500 RPM. Both share FAA Type Certificate 1E4, firing order 1-4-5-2-3-6, magneto timing of 20 degrees BTC, magneto point clearance of .010 ± .002, a Sky-Tec 149-24PM 28-volt starter, an Electrosystems 90-amp 28-volt alternator P/N 680-501, and an Electrosystems VR-320 voltage regulator P/N 694-020. Oil sump capacity is 12 U.S. quarts with 9.25 quarts usable. Specified fuel is aviation grade 100/100LL.

Magnetos differ by model: Slick 6351 (L/H) and 6350 (R/H) on the 6X; Slick 6361 (L/H) and 6360 (R/H) on the 6XT. Both airplanes use a three-blade Hartzell HC-I3YR-1RF / F7663DR propeller, 78 in. diameter (77 in. minimum). Low-pitch / high-pitch blade angles at the 30-inch station are 12.4° ± 0.2° and 32° ± 1° on the 6X, and 15.2° ± 0.2° and 34.0° ± 0.5° on the 6XT. Governors are Hartzell V-5-4 (6X) and V-5-6 (6XT).

Four fuel tanks (two interconnected cells in each wing) hold 53.5 U.S. gallons per wing, 107 gallons total onboard and 102 gallons usable. The electric fuel pump is a Weldon 28-volt unit P/N 461-750. Landing gear is fixed oleo (air-oil) using MIL-H-5606 in the struts and brakes. Wheel tread is 10 ft. 7 in., wheelbase 7 ft. 8 in., nose-wheel travel 30° ± 2° left and right. Nose and main tires are Type III 6.00 x 6, 8-ply Michelin Air, inflated to 35 psi nose and 55 psi main. Nose and main strut pressures under static load (empty weight plus full fuel and oil) are 225 ± 22.5 psi and 250 ± 25 psi.

The three-view in Chapter 6 lists a wingspan of 36 ft 2.04 in. (11.025 m), overall length of 27 ft 10.44 in. (8.495 m), and height of 9 ft 6.36 in. (2.905 m). Station references start at a fuselage datum 78.4 inches ahead of the wing leading edge at the straight-to-taper intersection; buttock line 0 is the airplane centerline; water line 0 is 20.5 inches below the cabin floor at the rear wing spar with the airplane level.

Vendor publications listed in the introduction (Lycoming, Hartzell, Slick, Garmin, Avidyne, S-TEC, Weldon, Parker Hannifin, Artex, Scott Aviation, and others) are called out wherever a component must be serviced to the vendor manual rather than only to this book.

Inspection Program, Time Limits, and Ground Handling

Chapter 5 is the working inspection engine of the Piper PA-32-301FT 6X and PA-32-301XTC 6XT Airplane Maintenance Manual 2003-2008. It separates scheduled work from special and unscheduled checks and points back to Chapter 4 for FAA-approved replacement times and structural intervals. Periodic Inspection Reports P/N 766-857 / 766-858 and Progressive Inspection Manuals P/N 767-027 / 767-028 are identified as snapshots of those ICA sections, not stand-alone substitutes. Time-limit text also covers Hartzell propeller and governor overhaul windows (five or six years, or 2000 / 2400 hours per the latest Hartzell Service Letter No. 61), alternator overhaul, magneto 100- and 500-hour inspections, and oxygen-system recharge-valve replacement on the 6XT.

Chapters 7 through 12 walk jacking, weighing, leveling, towing, taxiing, parking, mooring, placard location, fuel and oil replenishing, oleo servicing with MIL-H-5606, tire service, and the lubrication chart. Access-plate maps and station diagrams in Chapter 6 tell the mechanic where to open the airplane without guessing.

Airframe Systems a Shop Will Actually Touch

Flight-control chapters give cable inspection technique, pulley wear patterns, aileron bellcrank installation, rudder and steering pedal assembly, rudder-trim geometry, stabilator travel stops, flap torque-tube and position-switch rigging, and static-balance limits after paint or repair. Fuel work covers inboard aluminum tanks, outboard bladder cells, seven-year tank/wing-spar corrosion inspection, locking caps, selector valve and nylon filter bowl (no field disassembly of the selector), Weldon pump inspection, dual quantity-gauge bench test, and wing sight gauges. Landing-gear text disassembles main and nose oleos, fairings, Cleveland 40-120C main and 40-56B / 40-30665 nose wheels, and Cleveland 30-83A brakes, including lining tolerance and disk minimum thickness.

Environmental coverage includes ram-air and overhead ventilation, cabin heat ducting, and the optional Sanden compressor / Enviro evaporator air-conditioning circuit with charging, leak, and evacuation setups. Ice protection covers heated pitot-static plumbing plus the optional TKS weeping-wing system: porous-panel cross-section, proportioning units, fluid tank and sender, filter, nylon tubing, propeller slinger ring and blade boots. Electrical generation describes the 90-amp Electrosystems alternator (exploded view and diode/stator tests), belt tension, 20-amp standby alternator on later EFIS airplanes, aft-fuselage battery, and overvoltage-relay checks. Vacuum pumps carry a vane-wear inspection port procedure. Structures, doors, fuselage, wings, windows, and empennage chapters cover skin repairs, thermoplastic patching, metal/wire stitching, electrical bonding millivolt-drop tests (including G1000 LRU grounds), wing-attach bolt practice, and control-surface balancing.

Avionics, Engine Installation, and Schematics

Chapter 22 documents the S-TEC System 55X rate-based autopilot: component locator, pitch/roll/trim servos, clutch-torque adjustment, and flap compensator. Chapter 34 is the large navigation chapter and treats both factory EFIS paths found on these serials — Avidyne Entegra (PFD, MFD, magnetometer/OAT) and Garmin 1000 (GDU 1040 displays, GMA 1347, GIA 63W, GEA 71, GTX 33, GDC 74A, GTP 59, GRS 77, GMU 44, GDL 69/69A) — including configuration-mode navigation, software load, magnetometer calibration, engine-page sensor checks, and lighting curves. Conventional pitot/static testing and the optional King KCS-55A flux-valve heading system are also here. Communications cover the GMA-340 audio panel functional test on non-G1000 airplanes. Chapter 91 supplies torque charts and the electrical schematics the troubleshooting tables keep pointing to.

Powerplant chapters stay on the airframe side of the firewall: cowling, engine mounts and shock mounts, removal/installation, throttle and mixture cable rigging, air-bleed fuel nozzles, Slick magneto timing to the 20° BTC marks, impulse-coupling inspection, ignition-harness repair, Sky-Tec starter service, oil distribution and indicating, exhaust, and — on the 6XT — turbocharger V-band coupling 100-hour inspection, wastegate clearance, and lockwire practice. Lycoming overhaul limits remain in the Lycoming manuals listed in the introduction (direct-drive overhaul P/N 60294-7, parts catalogs PC-615 / PC-615-12, operators handbooks 60297-10 / 60297-23).

Put This Manual to Work

With the Piper PA-32-301FT 6X and PA-32-301XTC 6XT Airplane Maintenance Manual 2003-2008 on the bench, a mechanic can run the ICA inspection program, service oleos and brakes to the printed pressures and extensions, rig aileron, rudder, stabilator, flap, and propeller-governor controls to the charted travels and tensions, time magnetos, inspect TKS panels and porous-media flow, load and check G1000 or Entegra LRUs, charge or leak-test air conditioning, and follow Chapter 91 schematics when an annunciator or bus fault appears. Using the values printed for this serial block — not a Saratoga, Cherokee Six, or later PA-32 — keeps cable tensions, blade angles, strut pressures, and fuel quantities on the airplane that is actually in the hangar.
