TAMMS Reporting Compliance Suspense Date

3. TAMMS Reporting Compliance Suspense Date. Report compliance IAW paragraph 14a(1) NLT 22

May 2002.

Summary of the Problem.

a. History-- SOF AH--64--02--05 was issued to remove flight restrictions imposed by SOF

AH--64--00--08 (TB 1--1520--251--20--01). The purpose of the SOF was to inspect for the installation of sus-

pect High Power Switching Modules (HPSM), and for the installation of MWO 1--1520--251--55--07. Further

investigation revealed additional HPSM's that must be considered suspect. With the addition of these sus-

pect HPSM's, it is possible some aircraft released from the flight restrictions imposed IAW AH--64--00--08 may

still be at risk.

NOTE

After receipt of this TB and until 31 Jan 03, commanders will notify the POC in paragraph 16b

after control exchange of a GCU to ensure proper tracking of MWO 1--1520--251--55--06 ap-

plication.

b. For manpower/downtime and funding impacts, see paragraph 12.

The purpose of this TB is to:

(1) Revise the serial number listing of suspect HPSM's in paragraph 8a.

(2) Identify and replace suspect HPSM's.

End Items to be inspected. All Army AH--64D aircraft.
