Correction Procedures.
NOTE
Contact LAR for E--mail photos of installation of lockwire.
a. Safe aircraft.
b. Remove panels R200,L200 and L540.
c.
Identify the following connectors:
(1) For AH--64A:
Lateral Servocylinder
P225 and P415
Collective Servocylinder
P227 and P417
Longitudinal Servocylinder
P219 and P408
Directional Servocylinder
P223 and P215
(2) For AH--64D:
Lateral Servocylinder
P1046 and P1045
Collective Servocylinder
P1042 and P1041
Longitudinal Servocylinder
P1039 and P1038
Directional Servocylinder
P1319 and P1318
d. Turn each connector 1/4 turn counter--clockwise (do not remove connector). Then turn connector
1/4 turn clockwise or until connector is completely seated.
e. For the collective servocylinder and the lateral servocylinder connectors install safety wire from the
barrel of the connector body of the "P" side connector around the connector bracket and attach the safety
wire to the barrel of the connector body of the "P" side connector. Place protective sleeving on safety wire
to prevent chafing of connector bracket.
f. For the longitudinal servocylinder connectors, install safety wire from the barrel of the connector
body of the "P" side of one connector to the "P" side barrel of the connector body of the second connector,
around the connector bracket and attach the safety wire to the initial "P" side connector barrel. Place protec-
tive tubing on the safety wire to prevent chafing of the connector bracket.
g. For the directional servocylinder connectors, install safety wire from the barrel of the connector of
the "P" side of one connector to the "P" side barrel of the connector body of the second connector, around
the connector bracket, between the "J" side connectors and the skin of the vertical stabilizer and attach the
safety wire to the "P" side connector barrel. Place protective tubing on the safety wire to prevent chafing of
the connector bracket.
CAUTION
Ensure the safety wire does not pre--load the "P" side of the connector in
either direction. Ensure the protective sleeving is placed such that no
chafing condition between the safety wire and the connector bracket exists.
NOTE
Hydraulic System and Flight Controls MOC is not required. The BUCS self
test on the AH--64A and EBUCS (Enhanced Back--Up Control System) IBIT
(Initial Built-In Test) on the AH--64D will verify the systems during preflight
checks.
