What to do
Operators and maintainers of PW200 series engines should review Pratt & Whitney Service Information Letter PW200-065 and follow the prescribed maintenance instructions. Drying runs must be conducted soon after compressor washes within the time limits specified in the maintenance manual. For further information, stakeholders can contact Transport Canada or Dean Ciaschini at the Continuing Airworthiness office.
Summary
The Transport Canada Civil Aviation Safety Alert CASA 2017-05 addresses the Pratt & Whitney Canada PW206, PW207, and PW210 turboshaft engines. It reminds owners, operators, and maintenance personnel that drying runs must be conducted shortly after compressor washes to prevent corrosion and maintain engine serviceability. The alert emphasizes adherence to the engine maintenance manual for specific drying run timing and duration.
What changed
CASA 2017-05 introduces a mandatory reminder for operators to perform post compressor wash drying runs within the recommended time limits. It highlights that delaying drying runs until the next day after the last flight can cause corrosion and damage to internal engine components. This alert serves as a new safety communication rather than an amendment to existing regulations.
Why it matters
This alert is critical for aviation professionals because improper drying after compressor washes can lead to corrosion, reducing engine reliability and increasing maintenance costs. Operators and maintenance teams must ensure timely drying runs to preserve engine integrity and comply with manufacturer guidelines. Failure to comply could adversely affect engine performance and safety.
