Inspection Procedures.
a. As a follow-up to SOF AH-64-01--02, perform the following:
(1) Review DA Form 2408-16; identify, record, and report in accordance with paragraph 14.b.
both the serial number of tail rotor swashplate installed on aircraft and the serial number of bearing
installed in swashplate.
(2) Physically inspect aircraft to determine whether the serial number of the swashplate
installed is the same as the serial number identified on DA Form 2408-16. If the serial numbers do not
match, contact the 2410 hotline to determine the swashplate bearing serial number.
(3) If tail rotor swashplate installed is one of below-listed suspect serial numbers or if DA
Form 2408-16 or 2410 hotline data indicates that any swashplate contains one of the listed suspect
bearing serial numbers, perform corrective action in accordance with paragraphs 9.a. and 9.b.
NOTE
The swashplate assemblies previously identified in SOF
AH-64-01-02 that remain suspect are included in the list below.
Swashplate assemblies that are no longer suspect have been
removed.
NOTE
Some swashplate markings and DA Forms 2408-16 may reflect
only the last 4 digits of the serial number and will not contain the
"009999" prefix.
