Airworthiness Directives; Gulfstream Model GIV-X and GV-SP Series Airplanes


AGENCY:
 
Federal Aviation Administration (FAA), Department of Transportation (DOT).


ACTION:
 
Final rule; request for comments.


–––––––––––––––––––––––––––––––––––


SUMMARY:
 
The FAA is revising an existing airworthiness directive (AD), which applies to certain


Gulfstream Model GIV-X and GV-SP series airplanes. That AD currently requires revising the


Limitations section of the airplane flight manual (AFM) by incorporating new procedures to follow in


the event that the cockpit displays go blank or malfunction. This AD allows for the use of alternative


AFM revisions for a certain subset of the existing applicability. This AD results from a report that all


four of the cockpit flight panel display units simultaneously went blank during flight. We are issuing


this AD to ensure that the flightcrew is advised of the appropriate procedures to follow in the event


that the cockpit displays go blank or malfunction, which could result in a reduction of the flightcrew's


situational awareness and possible loss of control of the airplane.


DATES:
 
The effective date of this AD is March 13, 2006.


On March 13, 2006 (71 FR 9436, February 24, 2006), the Director of the Federal Register


approved the incorporation by reference of certain other publications.


We must receive any comments on this AD by June 12, 2006.

SUPPLEMENTARY INFORMATION:


Discussion


On February 14, 2006, we issued AD 2006-04-13, amendment 39-14495 (71 FR 9436, February


24, 2006). That AD applies to certain Gulfstream Model GIV-X and GV-SP series airplanes. That


AD requires revising the Limitations section of the airplane flight manual (AFM) by incorporating


new procedures to follow in the event that the cockpit displays go blank or malfunction. That AD


resulted from a report that all four of the cockpit flight panel display units simultaneously went blank


during flight. The actions specified in that AD are intended to ensure that the flightcrew is advised of


the appropriate procedures to follow in the event that the cockpit displays go blank or malfunction,


which could result in a reduction of the flightcrew's situational awareness and possible loss of control


of the airplane.


Actions Since AD Was Issued


Since we issued AD 2006-04-13, the European Aviation Safety Agency (EASA) informed us


that the information contained in the Joint Aviation Authority (JAA) Gulfstream AFM revisions is


considered acceptable for airplanes operated under and in accordance with the JAA and EASA


regulations, supervision, and oversight, and should be added to the AD. We inadvertently omitted


that information from AD 2006-04-13; therefore, we have added a new Note 2 to this AD to give


credit for those revisions.


Relevant Service Information


We have reviewed the revisions to the Limitations section of Gulfstream G350, G450, G500, and


G550 AFMs, as listed in the table below:
