FAA Orders Pratt & Whitney Engine Crack Checks—Takeoff Safety Boost
Published Date: 3/4/2025
Rule
Summary
The FAA is making new rules for certain Pratt & Whitney engines to keep flights safe. If your plane has one of these engines, you’ll need to check a specific part for cracks regularly and replace it if it’s damaged. These inspections start soon and could cost some money, but they help prevent serious problems during takeoff.
Analyzed Economic Effects
2 provisions identified: 0 benefits, 2 costs, 0 mixed.
Mandatory ultrasonic inspections and fixes
If your airplane has one of the affected Pratt & Whitney engines with the HPC 7th-stage axial rotor, you must perform initial and repetitive angled ultrasonic inspections (AUSI) of that rotor to check for cracks. If inspectors find cracks, you must replace the HPC 7th-stage axial rotor to address the unsafe condition.
Rule applies to specific PW engine models
This airworthiness directive applies only to certain Pratt & Whitney engines listed by model when they have a specific high-pressure compressor (HPC) 7th-stage axial rotor installed. The affected models are: PW1519G, PW1521G, PW1521GA, PW1521G-3, PW1524G, PW1524G-3, PW1525G, PW1525G-3, PW1919G, PW1921G, PW1922G, PW1923G, and PW1923G-A.
