Technical Notice

AIRBUS A320/A330/A340 NO: 31-013 R02 PAGE 1 OF 10

The information in the Technical Notice does not supersede that contained in Aircraft Manuals or otherApproved Publications unless specifically stated.

Form No: ENG/TS/GEN/052

Subject:

Applicability:

Background:

ASN 102 issued by CAASL specifies the requirement of an annual DFDR data downloading for

parameter quality check to ensure that the recorder operates correctly for the nominal

duration of the recording. In addition, DFDR data are used for analysing abnormal events.

Instead of removing DFDR from the aircraft, on wing DFDR data downloading is possible with

a suitable tool by using it as per the AMM procedure. The tool to be connected to the frontconnector of the DFDR and downloading is done while the recorder is energised.

ALK has acquired “Honeywell EHHDLU DFDR Data Downloading tool (P/N 69001074-060)” for

this purpose, which can be used for on wing DFDR data downloading on the Honeywell Digital

Flight Data Recorder part numbers listed in Table 2 of the “Limitations” section of this TN.

This TN has been issued to specify the supplementary procedure to be followed when

downloading the DFDR data on-wing using above Honeywell EHHDLU tool.

Recommendations:

When carrying out AMM tasks mentioned below, using Honeywell EHHDLU DFDR Data

Downloading tool, maintenance personnel must follow instructions for DFDR installed as

detailed in Appendix-A together with respective AMM tasks.

AMM task for A320 Fleet

Readout Procedure of the Digital Flight Data Recorder TASK 31-33-00-710-009-A

AMM task for A330 & A340 Fleet

Readout Procedure of the Digital Flight Data Recorder TASK 31-33-00-710-807-A

Following items are required for an on wing DFDR data download using Honeywell EHHDLUdownloading tool.

1. Honeywell Handheld computer (P/N 69001338-001)
