Gulfstream Aerospace LP (Type Certificate Previously Held by Israel Aircraft Industries, Ltd.) Airplanes
This AD applies to Gulfstream Aerospace LP (Type Certificate previously held by Israel Aircraft Industries, Ltd.) Model Gulfstream G150 airplanes, certificated in any category, all serial numbers.
We are superseding Airworthiness Directive (AD) 2013-03-23 for all Gulfstream Aerospace LP (Type Certificate previously held by Israel Aircraft Industries, Ltd.) Model Gulfstream G150 airplanes. AD 2013-03- 23 required revising the airplane flight manual (AFM) to include procedures to advise the flightcrew of certain runway slope and anti- ice corrections and takeoff distance values. This new AD requires revising the Performance section of the AFM, which includes the revised procedures. This AD was prompted by the issuance of a revision to the AFM, which modifies runway slope and anti-ice corrections to both V<INF>1</INF> and takeoff distance values. We are issuing this AD to prevent the use of published, non-conservative data, which could result in the inability to meet the required takeoff performance, with a consequent hazard to safe operation during performance-limited takeoff operations.
This paragraph restates the actions required by paragraph (g) of AD 2013-03-23, Amendment 39-17357 (78 FR 11567, February 19, 2013). Within 60 days after March 26, 2013 (the effective date of AD 2013-03-23), revise Section V, Performance, of the Gulfstream G150 AFM to include the information in Gulfstream G150 Temporary Revision (TR) 3, dated December 14, 2011. This TR introduces corrections for runway slope. Operate the airplane according to the procedures in this TR.
Note 1 to paragraph (g) of this AD: The AFM revision required by paragraph (g) of this AD may be done by inserting copies of Gulfstream G150 TR 3, dated December 14, 2011, into the AFM. When this TR has been included in general revisions of the AFM, the general revisions may be inserted in the AFM, provided the relevant information in the general revision is identical to that in Gulfstream G150 TR 3, dated December 14, 2011, and the TR may be removed.
Within 60 days after the effective date of this AD, revise the Gulfstream G150 AFM to incorporate the information in Section V, Performance, of the Gulfstream G150 AFM G150-1001-1, Revision 17, dated April 17, 2013. Revision 17 of this AFM contains revisions of runway slope and anti-ice corrections to the V 1 and takeoff distance values. Before further flight, after accomplishing the revision, remove Gulfstream G150 TR 3, dated December 14, 2011, or the information contained in Gulfstream G150 TR 3, dated December 14, 2011, from the AFM. Operate the airplane according to the procedures in Section V, Performance, of Gulfstream G150 AFM G150-1001-1, Revision 17, dated April 17, 2013. Revising the AFM to Gulfstream G150 AFM G150-1001-1, Revision 17, dated April 17, 2013, terminates the action required by paragraph (g) 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.
