INSTRUCTIONS FOR CONTINUED AIRWORTHINESS WARNING: INSTRUCTIONS FOR CONTINUED AIRWORTHINESS (ICA) FOR ALL NON-PIPER APPROVED STC INSTALLATIONS ARE NOT INCLUDED IN THIS MANUAL. WHEN A NON-PIPER APPROVED STC INSTALLATION IS INCORPORATED ON THE AIRPLANE, THOSE PORTIONS OF THE AIRPLANE AFFECTED BY THE INSTALLATION MUST BE INSPECTED IN ACCORDANCE WITH THE ICA PUBLISHED BY THE OWNER OF THE STC. SINCE NON-PIPER APPROVED STC INSTALLATIONS MAY CHANGE SYSTEMS INTERFACE, OPERATING CHARACTERISTICS AND COMPONENT LOADS OR STRESSES ON ADJACENT STRUCTURES, THE PIPER PROVIDED ICA MAY NOT BE VALID FOR AIRPLANES SO MODIFIED. The PIPER PA-34-220T Seneca III/IV Maintenance Manual constitutes the Instructions for Continued Airworthiness in accordance with Federal Aviation Regulations (FAR) Part 23, Appendix G. Chapter 4 contains the Airworthiness Limitations section (4-00-00) and the Inspection Program is in Chapter 5 (5-20-00). 2. GENERAL This publication is prepared in accordance with the General Aviation Manufacturers Association (GAMA) Specification No. 2, with respect to the arrangement and content of the System/Chapters within the designated Chapter/Section-numbering system. WARNING: USE ONLY GENUINE PIPER PARTS OR PIPER APPROVED PARTS OBTAINED FROM PIPER APPROVED SOURCES, IN CONNECTION WITH THE MAINTENANCE AND REPAIR OF PIPER AIRPLANES. This manual does not contain hardware callouts for installation. Hardware callouts are only indicated where a special application is required. To confirm the correct hardware used, refer to the PA-34-220T Parts Catalog P/N 761-750 and FAR 43 for proper utilization. Genuine PIPER parts are produced and inspected under rigorous procedures to insure airworthiness and suitability for use in PIPER airplane applications. Parts purchased from sources other than PIPER, even though identical in appearance, may not have had the required tests and inspections performed, may be different in fabrication techniques and materials, and may be dangerous when installed in an airplane. Reworked, salvaged or those parts obtained from non-PIPER approved sources, which the service history is unknown or cannot be authenticated, may have been subjected to unacceptable stresses or temperatures or have other hidden damage, not discernible through routine visual or usual nondestructive testing. This may render the part, component or structural assembly, even though originally manufactured by PIPER unsuitable and unsafe for airplane use. Piper Aircraft, Inc. expressly disclaims any responsibility for malfunctions, failures, damage or injury caused by use of non-PIPER approved parts. NOTE: Piper Aircraft, Inc. expressly reserves the right to supersede, cancel and/or declare obsolete any part, part numbers, kits or publication that may be referenced in this manual without prior notice. Be sure to include the airplane serial number (see Effectivity, below) in any correspondence or communication concerning your airplane. PIPER AIRCRAFT PA-34-220T AIRPLANE MAINTENANCE MANUAL 3.

SERIAL NUMBER EXPLANATION This manual encompasses airplanes manufactured under two different serial numbering systems. A. The earlier system is comprised of four sets of numbers, as shown in the following example: B. The later system is comprised of three sets of numbers, as shown in the following example: 5. ASSIGNMENT OF SUBJECT MATERIAL This publication is divided into industry standard, three element, numeric subject groupings as follows: A. System/Chapter - The various groups are broken down into major systems such as Environmental Systems, Electrical Power, Landing Gear, etc. They are assigned a number, which becomes the first element of the standardized numbering system. Thus, the element “28” of the number 28-40-00 refers to the chapter “Fuel”. Everything concerning the fuel system will be covered in this chapter. B. Sub-System/Section - The major systems/chapters of an airplane are broken down into subsystems. These sub-systems are identified by the second element of the standard numbering system. The element “40” of the number 28-40-00 concerns itself with the indicating section of the fuel system. C. Unit/Subject - The individual units within a sub-system/section may be identified by the third element of the standard numbering system. The element “00” of the number 28-40-00 is a subject designator. This element is assigned at the option of the manufacturer and is normally zeroed out by PIPER. Refer to the Chapter/Section Index Guide, below, for a complete breakdown and list. The material is arranged in ascending numerical sequence. 6. PAGINATION The Chapter - Section (i.e. - 28-40-00) numbering system explained above forms the primary page numbering system for this manual. Within each Section, pages are numbered consecutively beginning with Page 1 (i.e. - 28-40-00, Page 1).

Page 1 Reissued: November 29, 1993 1C17 GENERAL Jacking the airplane is necessary to perform servicing of the landing gear and the operations. The jacking operation can be performed through the use of conventional tripod jacks, or in other situations, (emergency, post-accident lifting), slings or air bags should be used. If wing and/or fuselage shoring is required, make sure the support is contoured to conform with the surface it is supporting. JACKING (Refer to Figure 7-1.) 1. Align the jacks under the wings with their respective pads on the wing front spar. 2. Attach a tail stand with approximately 600 pounds ballast, to the tail skid. — CAUTION — ENOUGH SUPPORT BALLAST MUST BE ADDED TO THE TAILSTAND TO PREVENT THE AIRPLANE FROM TIP- PING FORWARD ON ITS NOSE SECTION. MAKE SURE TO ACCOUNT FOR SOMEONE IN THE FUSELAGE IF APPLICABLE. 3. Carefully raise jacks until all three wheels are clear of the surface. — CAUTION — IF THE HYDRAULIC SYSTEM IS TO BE SERVICED AT THIS POINT, THE FREE FALL KNOB SHOULD BE PULLED OUT. FOR FURTHER INFORMATION, REFER TO CHAPTER 32. Figure 7-1.

The airplanes are provided with a means for longitudinal and lateral leveling. The airplanes may be leveled while on jacks, during the weighing procedure while the wheels are on the scales, or while the wheels are on the ground. To level the airplane for purposes of weighing or rigging, the following procedures may be used: 1. To longitudinally level the airplane, partially withdraw the two leveling screws located immediately below the left front side window. Place a level on these screw heads and adjust the jacks until the level is centered. Should the airplane be either on scales or on the floor, first block the main gear oleos to full extension; then deflate the nose wheel until the proper position is reached. 2. To laterally level the airplane, place a level across the baggage compartment floor along the rear bulk- head. Raise or lower one wing tip by deflating the appropriate tire on the high side of the airplane or adjust either jack until the bubble of the level is centered. Figure 8-1.

The airplane may be weighed by the following procedure: 1. Position a scale and ramp in front of each of the three wheels. 2. Secure the scales from rolling forward and tow the airplane onto the scales. 3. Remove the ramp so as not to interfere with the scales. 4. If the airplane is to be weighed for weight and balance computations, level the airplane. Figure 8-2.

The tow bar engages front axle inside fork. — CAUTION — WHEN TOWING WITH POWER EQUIPMENT, DO NOT TURN THE NOSE GEAR IN EITHER DIRECTION BEYOND ITS STEERING RADIUS LIMITS AS THIS WILL RESULT IN DAMAGE TO THE NOSE AND STEERING MECHANISM. WHEN MOVING THE AIRCRAFT FORWARD BY HAND, AVOID PUSHING ON THE TRAILING EDGE OF THE AILERONS AS THIS WILL CAUSE THE AILERON CON- TOUR TO CHANGE RESULTING IN AN OUT-OF-TRIM CONDITION. In the event towing lines (rope) are necessary, they should be attached to both main gear struts as high up on the tubes as possible. Lines should be long enough to clear the nose and/or tail by not less than15 feet, and a qualified person must ride in the pilot's seat to maintain control by use of the brakes. TAXIING Before attempting to taxi the airplane, ground personnel must be checked out by a qualified pilot or other responsible person. Each starting and shutdown procedures should be covered as well. When it is ascertained that the propeller back blast and taxi areas are clear, apply power to start the taxi roll and perform the follow- ing checks: 1. Taxi forward a few feet and apply brakes to determine their effectiveness. 2. Taxi with propellers set in low pitch, high rpm setting. 3. While taxiing, make slight turns to ascertain the effectiveness of steering. 4. Observe wing clearances when taxiing near buildings or other stationary objects. If possible, station a guide outside the airplane to observe. 5. When taxiing on uneven ground, look for and avoid holes and ruts. 6. Do not operate the engines at high rpm when running up or taxiing over ground containing loose stones, gravel, or any loose material that may cause damage to the propeller blades. — NOTE — Refer to Figure 9-1 for aircraft turning distance.

AIRCRAFT FINISH CARE CLEANING — WARNING — DO NOT USE GASOLINE, KEROSENE, ALCOHOL, BEN- ZENE, CARBON TETRACHLORIDE, THINNER, ACETONE, OR WINDOW CLEANING SPRAYS TO CLEAN AIRPLANE. CLEANING EXTERIOR SURFACES The airplane should be washed with a mild soap and water solution. Harsh abrasives or alkaline soaps or detergents could scratch painted or plastic surfaces or corrode metal. Cover areas where a cleaning solution could cause damage. To wash the airplane use the following procedure: 1. Flush away loose dirt with water. 2. Apply cleaning solution with a soft cloth, a sponge or a soft brush. 3. To remove exhaust stains, allow the solution to remain on the surface longer. 4. To remove stubborn oil and grease stains, use a soft cloth dampened with naphtha. 5. Rinse all surfaces thoroughly. 6. Any good automotive wax may be used to protect and preserve painted surfaces. Soft cleaning cloths or a chamois should be used to prevent scratches when cleaning or polishing. A heavier coat of wax on leading surfaces will reduce the abrasion problems in these areas. Refer to surface de-ice cleaning procedures. CLEANING WINDSHIELD AND WINDOWS — CAUTION — USE ONLY WATER AND MILD SOAP WHEN CLEANING THE HEATED WINDSHIELD. USE OF ANY OTHER CLEANING AGENT OR MATERIAL MAY CAUSE DISTORTION OR DAMAGE TO WINDSHIELD COATINGS. 1. Remove dirt, mud and other loose particles from exterior surfaces with clean water. 2. Wash interior and exterior window surfaces with mild soap and warm water. Use a soft cloth or sponge in a straight back and forth motion. Do not rub harshly. 3. Remove oil and grease with a cloth dampened with Plexiglas Polish and Cleaner, P/N 403D or similar substance conforming to Federal Specification (P-P-560) or kerosene. 4. Rinse windows thoroughly and dry with soft lint-free cloth. PIPER AIRCRAFT PA-34-220T AIRPLANE MAINTENANCE MANUAL 12-00-00 Page 1 Reissued: November 29, 1993 1E6 — WARNING — DO NOT USE GASOLINE, ALCOHOL, BENZENE, CARBON TETRACHLORIDE, THINNER, ACETONE, STRONG SOL- VENTS OR WINDOW CLEANING SPRAYS. DO NOT USE PLASTIC CLEANER ON HEATED GLASS WINDSHIELDS. 5. A superficial scratch or mar in plastic can be removed by polishing out the scratch with jeweler's rouge. 6. When windows are clean, apply a thin coat of polishing wax. Rub lightly with a soft cloth. Do not apply wax to heated windshields with electrical heating elements. 7. Apply REPCON repellent or equivalent to windows and windshield to improve visibility during flights through rain. Apply only according to manufacturer’s instructions. (Refer to Chapter 91, Consumable Materials.) CLEANING INTERIOR 1. Vinyl interior surfaces may be cleaned with a damp cloth and mild soap and water solution. 2. Leather may be cleaned with a mild hand soap and water solution or with a saddle soap. Follow the pre- cautions which apply to the cleaning of any fine leather product. Avoid saturation and never use deter- gents or harsh cleaning solutions on leather. — CAUTION — USE OF COMMON HOUSEHOLD CLEANERS AND POLISHES ON WOOD LAMINATED SURFACES COULD BE VERY HARMFUL. 4. Wood laminated surfaces should be maintained using only a high grade furniture wax. 5. All upholstery fabrics are Scotchguard treated and may be cleaned as follows: Spilled oily and watery liquids will generally bead up on the fabric and can be blotted away leaving little or no stain. Blot spills up as quickly as possible with an absorbent cloth, tissue or sponge. If the material is a solid or semi-solid, such as butter, remove the excess by gently scraping with a table knife. Often, blotting will remove all traces of stain but if the staining agent is not completely removed by blotting, the following techniques are suggested: Water-based stains such s ketchup, milk, ice cream, coffee: Wipe the stain with a cloth wet with water containing a detergent or ammonia (4 fluid ounces of ammonia to one gallon of water). repeat if necessary. Oil based stains such as salad dressing, butter or mayonnaise may be removed by either of the following procedures: Apply “Texize K-2R Spot Remover” by spraying or rubbing into the fabric and let dry. Vacuum off the residual powder. Repeat if necessary or wet a cloth with a solvent type spot cleaner such as “Energine” or “Renuzit” and wipe or gently rub the stained area. Turn cloth and rewet with solvent often. Repeat until stain disappears. To remove residual detergent left on the fabric, wipe the entire fabric surface with a cloth dampened with water. The cloth should be rinsed in clean water several times. This procedure will ensure that the treatment will continue to function. — NOTE — It is best to test the cleaner on an inconspicuous portion of the fabric to test for discoloration. Also avoid soaking or harsh rubbing. PIPER AIRCRAFT PA-34-220T AIRPLANE MAINTENANCE MANUAL 12-00-00 Page 2 Reissued: November 29, 1993 1E7 CLEANING CARPETS — WARNING — SOLVENT CLEANERS REQUIRE ADEQUATE VENTILA- TION. Use a small whisk broom or vacuum cleaner to remove dirt. For soiled spots, use a nonflammable dry cleaning fluid. Floor carpets may be removed and cleaned like any household carpet. ENGINE WASHING Before cleaning the engine compartment, place strips of tape on the magneto vents to prevent any solvent from entering these units. 1. Place a pan under the engine to catch waste. — CAUTION — DO NOT SPRAY SOLVENT INTO THE ALTERNATOR, STARTER, VACUUM PUMP, AIR INTAKE AND ALTER- NATE AIR INLETS. 2. With the engine cowling removed, spray or brush the engine with solvent or a mixture of solvent and degreaser, as desired. It may be necessary to brush areas that were sprayed where heavy grease and dirt deposits have collected in order to clean them. 3. Allow the solvent to remain on the engine from five to ten minutes; then rinse the engine clean with additional solvent and allow to dry. — CAUTION — DO NOT OPERATE ENGINE UNTIL EXCESS SOLVENT HAS EVAPORATED OR OTHERWISE BEEN REMOVED. 4. Remove the protective covers from the magnetos. 5. Lubricate controls, bearing surfaces, etc., per Lubrication Charts. (Refer to Chapter 12.) CLEANING SURFACE DEICING EQUIPMENT The deice boots should be cleaned when the aircraft is washed using a mild soap and water solution. In cold weather, wash the boots with the airplane inside a warm hangar if possible. If the cleaning is to be done outdoors, heat the soap and water solution before taking it out to the airplane. If difficulty is encountered with the water freezing on boots, direct a flow of warm air along the region being cleaned, using a portable type ground heater. As an alternate cleaning solvent, use benzol or non-leaded gasoline. Moisten the cleaning cloth in the sol- vent, scrub lightly and then with a clean dry cloth, wipe dry so that the cleaner does not have time to soak into the rubber. PIPER AIRCRAFT PA-34-220T AIRPLANE MAINTENANCE MANUAL 12-00-00 Page 3 Reissued: November 29, 1993 1E8 — CAUTION — PETROLEUM PRODUCTS SUCH AS THESE ARE INJURI- OUS TO RUBBER AND THEREFORE SHOULD BE USED SPARINGLY IF AT ALL. When deice boots are clean, a coating of B.F. Goodrich Icex should be applied. Icex is compounded to lower the strength of adhesion between ice and rubber surface of the deice boots. CLEANING LANDING GEAR Before cleaning landing gear, place plastic cover or similar material over wheel and brake assembly. 1. Place can under gear to catch waste. 2. Spray or brush gear area, as required, with solvent or mixture of solvent and degreaser. 3. Allow solvent to remain on gear for 5 to 10 minutes. Rinse gear with additional solvent and allow to dry. 4. Remove cover from wheel and remove catch can. 5. Lubricate gear per lubrication chart in Chapter 12.

Servicing of the filter is as follows: 1. Move the system's fuel selector valve to its off position. 2. Just outboard of the nacelle (refer to Figures 12-1 and 12-2), and under the wing, remove the access panel forward of the main spar at wing station 91.0. 3. With the drain cup, drain any fuel still in the bowl from the drain valve under the wing. 4. Disconnect the filter drain line from the bowl and cap the line. 5. Cut the safety wire and remove cap nut from bottom of bowl. 6. Remove bowl and O-ring seal from body. 7. Remove the check and retaining nuts from the stud, and slide the filter down off the stud. 8. The filter discs and washers need not be separated for normal cleaning. If necessary, proceed as follows: a. Remove retainer cup from outer tube. b. Slide discs and washers from outer tube. DO NOT use a sharp tool (screwdriver, etc.) to separate them. DRAINING FUEL SYSTEM The bulk of the fuel may be drained from the system by removing the flush type drain valve at the inboard end of each fuel tank. The remaining fuel in the system may be drained through the fuel filters and the two drains located on the lower right side of the fuselage inboard to the flaps. FILLING FUEL TANKS Each fuel system is filled through a single filler neck in its outboard tank. The standard fuel system involves two 24.5 gallon tanks per side comprising a total of 49 gallons per side. With the optional system, an additional bladder cell of 15 gallons is added per side giving a total of 64 gallons per side. Anti-icing additives complying with MIL-1-27686, may be added when filling the system. Refer to the next paragraph for the proper method. HANDLING OF DIRT AND MOISTURE IN FUEL SYSTEM — CAUTION — WHEN USING ADDITIVES, MAKE SURE THE CORRECT PROCEDURES ARE FOLLOWED.
