Piper PA-36 Pawnee Brave Service Manual 761471 – PA-36-285, PA-36-300 and PA-36-375

This service manual covers the Piper PA-36 Pawnee Brave in all three factory variants: the PA-36-285 with its Teledyne Continental 6-285 Tiara engine, the PA-36-300 with the Avco-Lycoming IO-540-K1G5, and the PA-36-375 with the Avco-Lycoming IO-720-D1CD. It is the same reference technicians have relied on for scheduled inspection, repair, removal and installation work across the Pawnee Brave line, and it walks through every major airframe and power plant system chapter by chapter. Document number 761471, originally issued February 14, 1973 and revised through August 4, 1989.

Put together, this Piper PA-36 Pawnee Brave service manual functions as the working reference for the whole airframe and both power plant families installed in the type. Structural chapters lay out the welded 4130 steel tube fuselage, the full cantilever wing with its two-bolt main spar attachment, the empennage and every removable skin and fairing, along with the fatigue-driven service life limits that govern spar fittings, carry-through assemblies and attachment bolts. Control chapters take the technician through rigging angles, cable tensions and static balance limits for ailerons, elevators and rudder. Landing gear material covers main and tail wheel assemblies, toe-in and camber alignment, wheel balancing and both the master cylinder and wheel brake cylinder rebuild sequences. Dispersal chapters cover the fiberglass hopper, spray boom, nozzles, subtank gate and dry material spreader, which is what makes this particular airframe so different from a standard utility aircraft. Power plant chapters are split three ways so the Continental 6-285 Tiara with its Vibratory Torque Control unit, the Lycoming IO-540 and the Lycoming IO-720 are each handled with their own cowling, fuel injection, ignition, magneto timing and control rigging procedures.

For anyone maintaining a Pawnee Brave, the practical value is in the details that factory training depends on: the exact torque values for wing attachment bolts and engine mount hardware, the fuel system pressure and flow values for both Continental and Lycoming injection, the magneto internal timing procedure with its painted-tooth and E-gap references, the alternator rotor resistance and output test figures, and the specific inspection intervals called out in the inspection report tables. Ag operators in particular will appreciate the dispersal system section, since the hopper, pump, boom and gate control work is covered to the same depth as the airframe itself.

Why This Manual Matters

Agricultural aircraft see some of the hardest service hours in general aviation. Between chemical exposure, dust, and short repetitive flights, Pawnee Brave airframes and engines accumulate wear fast, and guesswork is expensive. Having the correct rigging angles, the correct static balance limits, the correct torque values and the correct engine setup pressures in front of you is what separates a proper repair from one that comes back in fifty hours. The dispersal system sections matter just as much, because the pump, valves, booms and nozzles all interact and need to be set up as a matched system to spray evenly and consistently.
