MEMORANDUM FOR RECORD

FROM: 27 FGS/MXAAF

SUBJECT: CASP 2500 STATEMENT OF REQUIREMENTS

1. The purpose of this letter is to explain the requirements behind the purchase of new CASP 2500 units. The purchase is to provide the unit with the capability to perform charge and discharge of aircraft batteries. These items are necessary due to the backlog of F-22 aircraft batteries that are overdue and require a 30 day battery test that utilize the CASP 2500. Currently our unit has two that are at the manufacturer but with the amount of batteries that need to be tested we are hampered when it comes to aircraft ability.

2. See attached file with requirements for the CASP 2500.

Main Aircraft Battery Overfly AR Instructions Rev B 10 June 2024

WARNING:

IF AT ANY POINT, ENGINEERING DISPOSITION DECLARES THE BATTERY STATUS FAILED, THE BATTERY

WILL HAVE A DR SUBMITTED AGAINST IT IN JDRS AND SHIPPED TO THE REPAIR FACILITY WITH A DD

FROM 1577-1 (RED TAG) AFFIXED DOCUMENTING DATE AND TIME OF THE AR RESPONSE IDENTIFYING

THE FAILED CONDITION.

1. Remove the battery from the aircraft IAW TOD if not already removed and in TNB/FOM

IF A FAULT IS DISPLAYED ON THE CASP 2000/2500 DURING THE CHARGE OPERATION, REINITIATE THE

CHARGE SEQUENCE. IF FAULT PERSISTS, TROUBLESHOOT PER 8D2-61-2. AN INCOMPLETE OR

FAULTED CHARGE MAY RESULT IN A DISCHARGE TIME FAILURE.

2. Connect battery to the CASP 2000/2500 and fully Charge battery IAW 8D2-61-2 Chapter 5 (if using the CASP 2000), Table 5-2 or Chapter 6 (if using the 2500), Table 6-2. Affix a DD From 1756

(Blue Tag) to battery while in test phase awaiting AR Response.

DOCUMENTING DISCHARGE TIME FROM CASP IS REQUIRED FOR AR SUBMISSION. IF THE DISCHARGE

TIME DISPLAYED ON THE CASP AFTER STEP 3 IS LOST OR CLEARED, STEPS 1 AND 2 WILL BE REPEATED

BEFORE PROCEEDING.

3. Using best shop practices, measure the battery case temperature and retain this measurement for AR inclusion.

WARNING:

IF BATTERY CASE TEMP IS GREATER THAN 100 DEG FAHRENHEIT, DO NOT PROCEED AND SUBMIT AN

AR FOR ENGINEERING GUIDANCE.

4. Discharge battery IAW 8D2-61-2 Chapter 5 (if using the CASP 2000), Table 5-3 or Chapter 6 (if using the 2500), Table 6-3.

NOTE:

A FULLY CHARGED, HEALTHY BATTERY WILL TAKE LONGER THAN 8 HOURS TO DISCHARGE.

THE 30 DAY OVERFLY EXTENSION PERIOD BEGINS ON THE DATE/TIME OF THE MOST RECENT PASSING

DISCHARGE CYCLE TEST AS NOTED IN THE SUBMITTED INFO ONLY AR.

5. Using best shop practices, measure the battery case temperature and retain this measurement

IF THE DISCHARGE TIME IS LESS THAN 8 HOURS, 1 NEW CHARGE AND DISCHARGE CYCLE CAN BE

PERFORMED IN AN ATTEMPT TO RECOVER THE BATTERY. IF SECOND DISCHARGE CYCLE IS AGAIN, LESS

THAN 8 HOURS, SUBMIT ROUTINE AR AGAINST THE BATTERY PN AND SN, DOCUMENTING THE

DISCHARGE TIME(S) DISPLAYED ON THE CASP 2000/2500, THE NUMBER OF CHARGE/DISCHARGE

CYCLES, DATE OF DISCHARGE EVENT AND THE MODEL AND SN OF THE CASP USED ON THE BATTERY, AND THE BATTERY CASE TEMPERATURE READINGS AND AWAIT ENGINEERING DISPOSITION.

ENGINEERING WILL ANALYZE DATA PROVIDED IN THE AR. IF THE BATTERY IS DETERMINED TO BE

FAILED BASED ON THAT REVIEW, DESPITE IT PASSING THE 8 HOUR DISCHARGE TIME LIMIT, THE

INFO ONLY AR WILL BE UPGRADED TO A ROUTINE AR AND ENGINEERING WILL PROVIDE

DISPOSITION RECOMMENDATION FOR THAT BATTERY SN.

IF THE BATTERY IS NOT TO BE USED WITHIN THE SAME DAY AS SUCCESSFUL TESTING, BATTERY

MUST BE STORED AS A READY-FOR-USE AS DEFINED IN AR 23-LM-0011 WITH A DD FORM 1574

(YELLOW SERVICEABLE TAG) ANNOTATING THE DATE TIME OF THE LAST PASSING TEST.

6. Fully recharge the battery IAW 8D2-61-2 Chapter 5 (if using the CASP 2000), Table 5-2 or Chapter

6 (if using the 2500), Table 6-2.

7. Using best shop practices, measure the battery case temperature and retain this measurement

WARNING:

8. Submit an INFO ONLY AR against the battery PN and SN, documenting the discharge time(s) displayed on the CASP 2000/2500, the number of charge/discharge cycles, date of discharge event and the Model and SN of the CASP used on the battery, and the battery case temperature.

IF THE DISCHARGE TIME TOOK LONGER THAN 8 HOURS, AND NONE OF THE BATTERY CASE

TEMPERATURE READINGS WERE OVER 100 DEGREES FAHRENHEIT, THE PRELIMINARY ASSESSMENT OF

THE BATTERY IS ASSUMED GOOD, SUBMIT AN INFO ONLY AR AGAINST THE BATTERY PN AND SN, DOCUMENTING THE DISCHARGE TIME(S) DISPLAYED ON THE CASP 2000/2500, THE NUMBER OF

CHARGE/DISCHARGE CYCLES (IF APPLICABLE), DATE OF DISCHARGE EVENT, THE MODEL AND SN OF

THE CASP USED ON THE BATTERY, AND THE CASE TEMPERATURES READINGS. PROCEED WITH THE

FOLLOWING STEPS, AWAITING AR RESPONSE IS NOT REQUIRED.

9. Install battery IAW TOD.

10. Perform EPS check IAW TOD.
