Piper PA-28-161 Maintenance Manual

2. Station Reference Lines
To locate various airplane components that require maintenance and servicing, a method utilizing
fuselage station, wing station, buttock line and waterline designations is frequently employed in this
manual. Fuselage stations (F.S.), wing stations (W.S.), buttock lines (B.L.), and water lines (W.L.) are
reference points measured by inches in the vertical or horizontal direction from a given reference line.
The reference datum line (F.S. 0) is located 78.4 inches ahead of the wing leading edge at the
intersection of the straight and tapered section, or, 44.5 inches ahead of the lower edge of the firewall;
B.L. 0 and W.S. 0 are the centerline of the airplane; and W.L. 0 is 20.5 inches below the cabin floor as
measured at the rear wing spar with the airplane level.
