- 1. Obtain a New or Blank Compact Flash (CF) card.
- 2. Copy to the New or Blank CF card the appropriate ‘Header File’
- a) Header files are files copied to the New or Blank CF card that will instruct the computer unit what is desired to be downloaded.
- b) Header files needed to download Maintenance Data, Event Data and CRC Part Numbers can be obtained from ACSS Customer Services at +1-623-445-7070 or crc.acss@l-3com.com.
- 3. For downloading Maintenance Data, Event Data or CRC Part Numbers the aircraft does not need to be in an on-ground configuration.
- 4. Apply power to the computer unit.
- 5. Insert the CF card.
- 6. For ACSS part numbers 9005000-10000, -10101, -10202, and -10204 the DATA STATUS LED will UblinkU green once; this indicates the unit recognized that a CF card was inserted.
- 7. For ACSS part numbers 9005000-11203, -11801 and -55801 the DATA STATUS LED will UblinkU green while reading the header file and performing the action defined in the header file.
- 8. Flight Data Recording
- 1. T3CAS part numbers 9005000-10000, -10101, -10202, and -10204 only support FAT16 CF card formatting. T3CAS part numbers 9005000-11203, -11801 and -55801 support both FAT16 and FAT32 CF card formatting.
- B. Flight Data
- 1. Obtain a New or Blank CF Card.
- 2. Copy to the New or Blank CF Card the Appropriate Header File.
- 3. Header files are files copied to the New or Blank CF card that will instruct the computer unit what is desired to be downloaded.
- 4. For Flight Data Recording, the aircraft does not need to be in an on-ground configuration.

SYSTEM DESCRIPTION AND INSTALLATION MANUAL
T
3
CAS/Part No.9005000
The Airworthiness Limitations section is FAA approved and specifies maintenance
required under 14 CFR Secs. 43.16 and 91.403 of the Federal Aviation Regulations
unless an alternate program has been FAA approved.
Recommended Periodic Inspections are as follows:
● The TCAS directional antennas used with the T
3
CAS should be removed and the
underlying structure inspected for deterioration and corrosion in accordance with the
aircraft installation ICA.
● The ATC transponder(s) used with this system have test and inspections that are
required by FAR 91.413.
● For installations where hybrid surveillance is available (Applicable to Part No.
9005000-11801 and -55801), the hybrid surveillance function should be inspected in
accordance with the aircraft installation ICA. It is recommended that the hybrid
surveillance maintenance task be performed every 24 months to demonstrate and
verify that hybrid surveillance is (and has been) functional. For the recommended
procedure for performing the hybrid surveillance check, refer to Section 6, sub-
section Hybrid Surveillance Test / Fault Isolation Procedure.
In addition, per AC 20-151B, a periodic reliability report summarizing all of the
hybrid surveillance faults must be provided to the TCAS manufacturer no later
than every 18 months.
Instructions for Continued Airworthiness (ICA) documentation should be revised for the
following requirement if your aircraft operations are such that the T
3
CAS could remain
continuously powered for periods exceeding 144 hours (6 days).
Affected part numbers 9005000-10000, -10101, -10202.
The requirement for operators with one of the above part numbers, who might expect to
have extended periods of continuous power on is as follows:
• Re-start the T
3
CAS unit prior to exceeding 144 hours of continuous power, ensures
correct functionality/behavior.
• Re-start can be accomplished by removing T
3
CAS power for 10 seconds before re-
powering (to induce a cold re-start).
Note: An APU to Ground Power transfer can create a Cold Re-start on LRUs; however
the clean power switching of some aircraft in conjunction with the long Hold-Up capability
of the T
3
CAS may not induce a re-powering/cold re-start. Therefore you should not count
on aircraft power switching to provide a power reset or cold re-start.
K. ICA Changes
If there are changes to the Instructions for Continued Airworthiness, the installation
manual will be revised accordingly. When document revisions are approved, the ACSS
Customer Services extranet website is automatically updated. The Extranet site then
notifies the affected customers automatically by email, and on next login of the
documentation change.
