7.2.3 Perform magnetic particle inspection IAW TM-1-1520-264-23, section 4.27 with the following excep-
220.127.116.11 Select AC on the AC/DC power switch.
18.104.22.168 Place probe/yoke on the part so that the probe/yoke is parallel with the long axis of the shock strut.
22.214.171.124 Use a three-inch leg distance measured from the inside of the legs. Position one of the probe/yoke
legs a minimum of 1/4 inch above the weep hole maintaining contact with the shock strut.
Verify the probe/yoke legs are placed on housing, not on the
threaded ring. Improper placement of legs will generate an insuffi-
cient magnetic field.
126.96.36.199 Press the test switch and apply a light coat of magnetic particle media at the same time. Remove
the media momentarily before removing the current. Current should be applied for no more than five seconds.
Verify magnetic field with field indicator.
188.8.131.52 Inspect for cracks using the black light.
184.108.40.206 Demagnetize before moving to the next position, IAW TM-1-1520-264-23, para 220.127.116.11.
18.104.22.168 Reconfigure the probe/yoke legs to match the circumference of the shock strut, maintain the 3 inch
leg-to-leg distance as close as possible. Center the stripped area between legs of the probe/yoke.
22.214.171.124 Repeat steps 126.96.36.199. through 188.8.131.52.
7.2.4 If no evidence of cracking is found
184.108.40.206 Repaint the affected area utilizing primer (MIL-P 23377) and topcoat (MIL-C 46168) per Tm
220.127.116.11 Install shock strut IAW TM 1-1520-238-23-2, paragraph 3.18 or IETM.
