What to do

Affected operators must revise the airplane flight manuals for Gulfstream GVII-G500 and GVII-G600 models to include the updated limitations and procedures as specified in the directive. Compliance with these revisions is required by May 9, 2022. Pilots should verify wind conditions and approach speeds before landing and adhere strictly to the new operational limits to mitigate the unsafe condition.

Summary

The Airplane Flight Manual - Sections Limitations and Procedures - Amendment is a final rule Airworthiness Directive issued by the FAA affecting Gulfstream Aerospace Corporation Model GVII-G500 and GVII-G600 airplanes. It addresses unsafe conditions related to unintended alpha limiter engagement during landing flare in unstable air, which has caused high rate of descent landings and airplane damage. The directive mandates revisions to the airplane flight manuals to incorporate more restrictive limitations and procedures.

What changed

This amendment supersedes AD 2020-05-12 by retaining some prior requirements and adding or replacing several sections of the airplane flight manuals with more restrictive wind, gust, approach speed, and autothrottle limitations. It expands the operational limitations to better mitigate the risk of alpha limiter engagement during landing flare under unstable atmospheric conditions.

Why it matters

This directive is critical for aviation professionals as it addresses a safety hazard that can limit pilot pitch control during landing, potentially leading to loss of control and damage. Operators and maintenance teams must ensure compliance with the updated flight manual limitations to prevent similar incidents. It also highlights the importance of pilot adherence to wind and approach speed restrictions to maintain safe landing operations.
