FAA Proposes AD on Gulfstream G150 Takeoff Limits
An FAA review has found that some Gulfstream Aerospace G150s might not meet the takeoff requirements contained in the type’s airplane flight manual (AFM) because data for runway slope and anti-ice corrections to V1 and takeoff distances were originally “developed in a non-conservative manner.”
A proposed airworthiness directive–FAA-2012-0986–based upon a similar notice issued by the Civil Aviation Authority of Israel on March 2, 2012, proposes to update performance manual data because the U.S. agency believes it currently creates an “unsafe condition.”
The G150 type certificate, previously held by Israel Aircraft Industries, applies to all serial numbers of all aircraft certified in any category.
The FAA estimates the proposed AD would affect about 56 U.S.-registered aircraft and require approximately one work-hour per airframe to bring the manuals into compliance.
