Airworthiness Directives; Textron Aviation Inc. Airplanes
What happened
The FAA adopted a new airworthiness directive (AD) for certain Textron Aviation Inc., Model 408 airplanes, specifically serial numbers -0012 through -0051. This AD requires revising the aircraft maintenance manual (AMM) or instructions for continued airworthiness (ICA) to include a detailed inspection for the horizontal stabilizer spar and update serial effectivity for vertical stabilizer spar inspections. This action, signed by Donald Trump, is effective August 18, 2026, and is estimated to cost U.S. operators $2,380 in total.
Why it matters
This policy ensures that specific Textron Aviation Inc. airplanes undergo crucial inspections to prevent cracks in their horizontal and vertical stabilizers. Addressing these potential cracks maintains the structural integrity and controllability of the aircraft, preventing possible loss of control. This directly enhances aviation safety for these airplanes by mandating critical maintenance updates.
