Airworthiness Directive · Amendment 39-18693 · Landing gear
Gulfstream Aerospace Corporation Airplanes
This AD applies to Gulfstream Aerospace Corporation Model GV airplanes, certificated in any category, serial numbers 501 through 693 inclusive and serial number 699; and Model GV-SP airplanes, certificated in any category, serial numbers 5001 through 5433 inclusive.
We are adopting a new airworthiness directive (AD) for certain Gulfstream Aerospace Corporation Model GV and GV-SP airplanes. This AD was prompted by a new revision to the Airworthiness Limitations Section (ALS) of the Aircraft Maintenance Manual (AMM) based on fatigue and damage tolerance testing, and updated analysis. This AD requires revising the maintenance or inspection program to incorporate updated inspection requirements and life limits that address fatigue cracking of principal structural elements (PSEs). We are issuing this AD to ensure that fatigue cracking of PSEs is detected and corrected; such fatigue cracking could result in reduced structural integrity of the PSEs and critical components.
Within 12 months after the effective date of this AD, revise the maintenance or inspection program, as applicable, to incorporate the airworthiness limitations specified in Gulfstream Document GV-GER-9973, Summary of Changes to the GV Series Airworthiness Limitations, Revision C, dated January 8, 2015. The initial compliance times for the tasks identified in Gulfstream Document GV-GER-9973, Summary of Changes to the GV Series Airworthiness Limitations, Revision C, dated January 8, 2015, are at the applicable times specified in Gulfstream Document GV-GER-9973, Summary of Changes to the GV Series Airworthiness Limitations, Revision C, dated January 8, 2015, or within twelve months after the effective date of this AD, whichever occurs later.
Note 1 to paragraph (g) of this AD: Gulfstream Document GV-GER-9973, Summary of Changes to the GV Series Airworthiness Limitations, Revision C, dated January 8, 2015, specifies the following AMM revisions as additional sources of guidance for the actions required by paragraph (g) of this AD. For Model GV airplanes, AMM Revision 43, dated February 15, 2015; and for Model GV-SP airplanes, G500 or G550 AMM Revision 24, dated February 15, 2015, as applicable.
After the maintenance or inspection program has been revised as required by paragraph (g) of this AD, no alternative actions (e.g., inspections) or intervals may be used unless the actions or intervals are approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (i) of this AD.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
