**Federal Aviation Administration**

**14 CFR Part 39**
**[Docket No. FAA–2012–0986; Directorate Identifier 2012–NM–077–AD]** 

**RIN 2120–AA64**
**Airworthiness Directives; Gulfstream Aerospace LP (Type Certificate**  **Previously Held by Israel Aircraft Industries, Ltd.) Airplanes** 

**AGENCY :**  Federal Aviation Administration (FAA), DOT.

**ACTION :**  Notice of proposed rulemaking (NPRM).

**SUMMARY :**  We propose to adopt a new airworthiness directive (AD) for all Gulfstream Aerospace LP (Type Certificate Previously Held by Israel Aircraft Industries, Ltd.) Model Gulfstream G150 airplanes. This proposed AD was prompted by a review that determined that the runway slope and anti-ice corrections to V 1 and takeoff distances in the Gulfstream G150 Airplane Flight Manual (AFM) were presented in a non-conservative manner. This proposed AD would require revising the performance section of the AFM to include procedures to advise the flightcrew of certain runwayslope and anti-ice corrections and takeoff distance values. We are proposing this AD to prevent the use of published non-conservative data, which could result in the inability to meet the required take-off performance, with consequent hazard to safe operation during performance-limited take-off operations.

**DATES :**  We must receive comments on this proposed AD by November 5, 2012.

**ADDRESSES :**  You may send comments by any of the following methods:

• Federal eRulemaking Portal: Go to http://www.regulations.gov. Follow the instructions for submitting comments.

• Fax: (202) 493–2251.
