SECTION II
HANDLING AND SERVICING
2-1. INTRODUCTION. This section contains routine handling and servicing procedures that are most
frequently encountered. Frequent reference to this section will aid the individual by providing information such
as the location of various components, ground handling procedures, routine service procedures and lubrication.
When any system or component requires service other than the routine procedures as outlined in this section,
refer to the appropriate section for that component.
2-2. DIMENSIONS. The principal airplane dimensions are shown in Figure 2-1 and are listed in Table II-I.
2-3. STATION REFERENCE LINES. In order to facilitate the location of various components of the airplane
which require maintenance and servicing, a method utilizing fuselage station (Sta.), wing station or buttock line
(BL), and waterline (WL) designations is frequently employed in this manual. (Refer to Figure 2-2.) Fuselage
stations, buttock lines, and waterlines are reference points measured by inches in the vertical or horizontal
direction from a given reference line which indicates station locations of structural members of the airplane.
Station 0 of the fuselage is 44.5 inches ahead of the lower edge of the firewall; station 0 (BL) of the wing and
stabilator is the centerline of the airplane; and station 0 (WL) of the fuselage vertical stabilizer and rudder is 20.5
inches below the cabin floor as measured at the rear wing spar with the airplane level. The reference datum line
is located 78.4 inches ahead of the wing leading edge at the intersection of the straight and tapered section.
2-4. WEIGHT AND BALANCE DATA. When figuring various weight and balance computations, the empty,
static and gross weight, and center of gravity of the airplane may be found in the Weight and Balance Form of
the Airplane Flight Manual.
2-5. SERIAL NUMBER PLATE. The serial number plate is located on the left side of the fuselage near the
leading edge of the stabilator. The serial number should always be used when referring to the airplane on service
or warranty matters.
2-6. ACCESS AND INSPECTION PROVISIONS. The access and inspection provisions for the airplane are
shown in Figure 2-3. The component to be serviced or inspected through each opening is identified in the
illustration. All access plates and panels are secured by either metal fasteners or screws. To enter the aft section
of the fuselage, remove the upholstery panel.
— Caution —
before entering the aft section of the fuselage, be sure the airplane is supported at
the tail skid.
2-7.
TOOLS AND TEST EQUIPMENT. Because of the simplicity and easy accessibility of components, few
special tools outside normal shop tools will be required. Tools that are required may be fabricated from
dimensions given in the section that pertains to a particular component.
