Applicability:

Model GIV-X series aeroplanes, serial numbers (S/N) 4001 and subsequent; and Gulfstream Model GV-SP series aeroplanes, S/N 5001 and subsequent; on which Gulfstream Modification ASC-904 or production equivalent has been incorporated.

Requirement:

Revise the Limitations Section of the Gulfstream G350, G450, G500 and G550 Aircraft Flight Manuals (AFM) by including the applicable revision listed in Table 1 of this Directive.

Any further revisions to the AFM must contain the identical procedures in the Limitations Section of the AFM revisions as required by this Directive.

\n```\n\n| Background: | The United States Federal Aviation Administration has received a report indicating that all four of the cockpit flight panel display units simultaneously went blank during flight on a Gulfstream Model GV-SP aeroplane. The displays did not recover until the flightcrew pulled circuit breakers associated with the displays; subsequently, three of the four displays returned to normal. Initial investigation revealed discrepancies with the reversion logic of the advanced graphic modules. Similar display failures occurred during ground test operations. Such conditions, if not corrected, could result in a reduction of the flightcrew's situational awareness and possible loss of control of the aeroplane. |\n| ----------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |\n| | This Directive requires the revision of the Limitations section of the AFM by incorporating new procedures to follow in the event that the cockpit displays go blank or malfunction. The amendment of AFM is an interim measure and further rulemaking to correct the discrepancy is anticipated. |\n\n![](image.001.png) \nJames Coyne \nDelegate of the Civil Aviation Safety Authority\n\n15 March 2006","sortOrder":0},{"sectionNumber":"AD/G1159/45","sectionType":"part","heading":"AD/G1159/45","content":"## AD/G1159/45","sortOrder":1},{"sectionNumber":"Cockpit Flight Panel Displays","sectionType":"part","heading":"Cockpit Flight Panel Displays","content":"## Cockpit Flight Panel Displays","sortOrder":2},{"sectionNumber":"5/2006 DM","sectionType":"part","heading":"5/2006 DM","content":"## 5/2006 DM","sortOrder":3}],"analysis":{"summary":{"content_quality":"ok","complexity_score":2,"scope_assessment":{"changed":false,"description":"This instrument is an airworthiness directive that mandates a Flight Manual amendment for particular Gulfstream aeroplanes; it does not amend, repeal or otherwise alter any broader legislative framework."},"complexity_factors":["Applies only to specific serial number ranges within two Gulfstream model series (GIV-X and GV-SP)","Conditional on prior incorporation of a particular modification (ASC-904 or production equivalent)","Requires cross-referencing aircraft model with exact Flight Manual revision numbers and dates from an embedded table","Explicitly states the requirement is an interim action with further rulemaking anticipated"],"plain_english_summary":"This AD requires operators of Gulfstream GIV‑X/GV‑SP (G350, G450, G500, G550) with serials 4001+ (GIV‑X) or 5001+ (GV‑SP) and Gulfstream Mod ASC‑904 installed to insert a specified Aircraft Flight Manual Limitations revision within 10 days of the 22 Mar 2006 effective date.
