Applicability:

Airbus aircraft listed in Table 1, all manufacturer serial numbers (MSN), if equipped with Electronic Instrument System EIS1 standard V32 [Display Management computer (DMC) Part Number (P/N) 9615325032], EIS1 standard V40 [DMC P/N 9615325040], or EIS1 standard V50 [DMC P/N 9615325050].

Requirement:

1. Modify the aircraft by installing EIS1 software standard V60 (DMC P/N 9615325060) in accordance with the instructions of Airbus SB A320-31-1286 dated 22 January 2008 or later revision approved by the European Aviation Safety Agency (EASA).

2. EIS1 software standard V32 (DMC P/N 9615325032), EIS1 software standard V40 (DMC P/N 9615325040) or EIS1 software standard V50 (DMC P/N 9615325050) may not be installed on any aeroplane that has been modified in accordance with Requirement 1.

Note: EASA AD 2008-0198 refers.

Compliance:

For Requirement 1 - Not later than 30 November 2013.

For Requirement 2 - After modification of an aircraft in accordance with
Requirement 1.

This Airworthiness Directive becomes effective on 18 December 2008.

Background:

Two incidents have occurred on Airbus A320 family aircraft during an Airborne Collision Avoidance System (ACAS)/Traffic Alert and Collision Avoidance System (TCAS) Resolution Advisory (RA). One of the Human-Machine Interface (HMI) factors was the lack of visibility of relevant information on the Primary Flight Display (PFD).

\n```\n\n| | This condition, if not corrected, could result in erroneous interpretation of ACAS/TCAS RAs leading to an increased risk of mid-air collision.EIS1 software standard V60 introduces modifications to the vertical speed indication to further improve the legibility of ACAS/TCAS RAs. This modification consists of a change in the needle colour and thickness and an increase in width of the ACAS/TCAS green band. This Directive requires the introduction of the new software standard V60 and prohibits reinstallation of earlier software versions V32, V40 and V50. |\n| --- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |\n\n![](image.001.png) \nJames Coyne \nDelegate of the Civil Aviation Safety Authority\n\n7 November 2008","sortOrder":0},{"sectionNumber":"AD/A320/228","sectionType":"part","heading":"AD/A320/228","content":"## AD/A320/228","sortOrder":1},{"sectionNumber":"Electronic Instrument System Display Man","sectionType":"part","heading":"Electronic Instrument System Display Management Computer Software Update","content":"## Electronic Instrument System Display Management Computer Software Update","sortOrder":2},{"sectionNumber":"13/2008","sectionType":"part","heading":"13/2008","content":"## 13/2008","sortOrder":3}],"analysis":{"kimi_summary":{"content_quality":"ok","complexity_score":3,"scope_assessment":{"changed":false,"description":"This is a standard, targeted Airworthiness Directive addressing a specific safety-critical software deficiency.
