What to do
Operators of Textron Aviation Model 560XL airplanes must inspect the rivet of the throttle quadrant assembly sensor link and sensor drive arm pivot within 50 hours time-in-service from the effective date. If any defects are found, corrective actions including rivet replacement or rework must be performed. Comments on the AD can be submitted to the FAA by February 1, 2021.
Summary
The Federal Aviation Administration's Airworthiness Directive 2020-26-05 addresses certain Textron Aviation Inc. Model 560XL airplanes. This directive mandates inspection of the rivet connecting the throttle quadrant assembly sensor link and sensor drive arm pivot to prevent uncommanded engine acceleration due to rivet failure. The AD aims to ensure safe thrust control by correcting potential installation defects in these components.
What changed
This new airworthiness directive introduces mandatory inspections of the left and right throttle quadrant assembly sensor link and sensor drive arm pivot rivets on Model 560XL airplanes. It requires corrective actions such as rivet replacement or rework if improper installation or cracking is found. The compliance time is set at 50 hours time-in-service, which is more urgent than the previously recommended 170 hours or 6 months in the related service letter.
Why it matters
This AD is critical for aviation professionals because it addresses a safety risk where failure of the throttle quadrant assembly rivet can cause uncommanded engine acceleration and loss of thrust control. Operators and maintenance teams must act promptly to prevent potential loss of airplane control during flight. Compliance ensures continued airworthiness and reduces the risk of incidents related to throttle control failures.
