EASA 2023-0207

Requires replacement of Decomatic titanium screws of a specific manufacturing batch in certain serial-numbered Falcon 7X, 900EX, and 2000EX airplanes. Prompted by an investigation that found these screws underwent an improper heat-treatment process, leading to a hydrogen concentration rate above the allowable limit. If not corrected, this condition could lead to premature failure of a titanium screw installed in a critical location, possibly resulting in reduced structural integrity.
