FAA Demands Extra Checks on Airplane Valves for Safety's Sake
Published Date: 8/19/2025
Proposed Rule
Summary
If you fly or work with ATR42 or ATR72 airplanes, listen up! The FAA wants to make sure a key safety valve gets checked more often because it might fail if left too long without testing. This means regular tests and fixes to keep everyone safe, starting soon, with some extra work but no big price tag expected.

More Frequent PRSOV Tests for ATR Planes
The FAA proposes a rule that would require all ATR--GIE Avions de Transport R[eacute]gional Model ATR42 and Model ATR72 airplanes to have the pressure regulator and shut-off valve (PRSOV) functional test done more often. The rule would require repetitive functional tests of each PRSOV and any needed corrective actions because a design review found a risk of dormant failures.
