PIPER SENECA II SERVICE MANUAL

4-71. SURFACE PREPARATION FOR PRESSURE SENSITIVE SAFETY WALK.

The areas to which the pressure sensitive safety walk is to be installed must be free from all
contaminates and no moisture present. If liquid safety walk is installed the area must be prepared as
follows:

Area must be masked off to protect painted surfaces.

Apply suitable stripper MEK Federal Spec. TT-M-261, U.S. Rubber No. 3339 to wingwalk
compound. As compound softens, remove by using putty knife or other suitable tool.

Area must be clean and dry prior to painting.

Prime and paint area.

NOTE: Newly painted surfaces, shall be allowed to dry for 2.5 hours minimum prior to the

application of the safety walk.

4-72. APPLICATION OF PRESSURE SENSITIVE SAFETY WALK. (Kit 763 849V)

Wipe area with a clean dry cloth to ensure that no moisture remains on surface. Do not apply when
surface temperature is below 50°F. Apply pressure sensitive safety walk as follows:

Peel back the full width of the protective liner approximately 2 inches from the leading edge of the
safety walk.

Apply the safety walk to the wing area, begin at the leading edge, ensure proper alignment and
position from wing lap.

Remove the remaining protective liner as the safety walk is being applied from front to back of
wing area.

Roll firmly with a long handled cylindrical brush in both lengthwise directions. Make sure all edges
adhere to the wing skin.

Install leading edge retainer by inserting between wing leading edge fairing and forward wing spar.
Hold all parts in position by using existing fairing screws.

4-73. CONTROL SURFACE BALANCING.

4-74. CHECKING CONTROL SURFACE BALANCE.

The movable control surfaces have been statically balanced at the time of installation at the factory and
normally should not require rebalancing. Where possible the control surfaces were set with the balance
weight on the heavy side of the limits to permit paint touch-up without adjusting the balance weight. It
should be noted, however, that spare control surfaces are delivered unpainted and the static balance will
not necessarily fall within the limits provided. This is more pronounced on the stabilators and rudders.
The completed control surface, including paint, should be within the limits given in Table IV-IV. If the
surface is not to be painted, the balance weight will probably require adjustment. All replacement control
surfaces or surfaces that have been repainted or repaired should be rebalanced according to the
procedures given in Paragraphs 4-74 thru 4-78. The static balance of the surfaces must be as specified in
Table IV-IV.

Before balancing any control surface, it must be complete including tip, trim/servo tabs as applicable and
tab actuating arms or push rods with bearings as applicable and all optional equipment which is mounted
on or in the control surface when it is flown, including paint, position lights and wiring, static wicks,
scuff boots, etc.
