Station Reference Lines - Piper PA-32R-301 SARATOGA SP Maintenance Manual

C. 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 station, (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 which indicates station locations of
structural members of the airplane. F.S. 0 is 78.4 inches ahead of the wing leading edge; B.L. 0 is 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. The reference datum line is located 78.4 inches ahead of the wing leading edge at the intersection of the
straight and tapered section.
