(4) MAIN LANDING GEAR TORQUE LINK INSPECTION (PA-32-260 & 300)
NOTE: Installation of the service replacement improved torque link P/N 78032-000 relieves
this repetitive inspection requirement. The new links must be installed in pairs and
each pair will require two washers P/N 63312-002.
In PA-32-260 S/N’s 32-03, 32-04, 32-1 thru 32-7200037; and PA-32-300 S/N’s 32-15, 32-21,
32-40000 thru 32-7240118; for airplanes with main landing gear torque links (P/N 65691-000)
installed which have accumulated 800 hours or more time-in-service,
beginning at 800 hours
and each 500 hours thereafter, inspect as follows:
(a) Inspect each main landing gear torque link for cracks in areas shown in Figure 3-4. These
cracks may form just behind the large boss which attaches to the strut or to the wheel, and
in the center of the link progressing toward the edge. The following steps should be used
to make this inspection:
1 Remove paint from the area to be inspected, using acetone, MEK, or any suitable
commercial paint remover which does not contain wax.
2 Allow the cleaned part to dry thoroughly.
3 If cracks do not readily appear, inspect by one of the following methods
a 10X magnifying glass.
b Dye check or other penetrant inspection.
(b) Should cracks be detected, replace defective torque links prior to further flight
(c) If no cracks appear, make proper log book entry and return aircraft to service.
