Inspection Procedures.
a. Review aircraft DA Form 2408--16 and calculate current time since new (TSN) on all AH--64 Main
Rotor Pitch Housings. If the current time since new is less than 1553 hours TSN (AH--64A) or 1193 (AH--64D)
hours TSN the red horizontal dash //--// may be cleared. If the current time since new is greater than 1553
hours TSN (AH--64A) or 1193 (AH--64D) hours TSN refer to para 9 for correction procedures.
b. Provide a report including aircraft tail number, current aircraft hours, pitch housing S/N, and current
flight hours on each pitch housing to the logistic point of contact listed in para 16b.
Correction Procedures.
a. The Retirement Life of the Pitch Housing for both AH--64A and AH--64D models is 1193 flight hours.
Revision 7 of the AH--64A ISAQ did not increase the retirement life, however it provided a grace period for
fielded AH--64A aircraft through 23 Feb 2001, at which time the 1193 hour retirement life shall be complied
with. The grace period does not allow pitch housings installed on AH--64A aircraft to exceed 1553 flight hours.
The AH--64D ISAQ does not allow any such grace period nor does it allow pitch housings installed on AH--64D
aircraft to exceed 1193 hours.
b. Immediately remove and demilitarize IAW para 10, any pitch housing having more than 1193 hours
that are installed on AH--64D Longbow aircraft.
c. Immediately remove and demilitarize IAW para 10, any pitch housing on AH--64A Apache aircraft
havig more than 1553 flight hours.
