What to do
Owners and operators should review the SPI Blade Quality Escape letter dated June 8, 2022, to identify affected blades and check maintenance records for any subsequent full blade inspections after the last SPI overhaul. If no such inspection exists, they should return the propeller to SPI or a certificated entity for a full blade inspection as soon as possible. Any findings should be reported to Stockton Propeller, Inc. or the Oakland Flight Standards District Office, and negative inspection results should be submitted through normal service difficulty reporting channels.

What changed
This bulletin introduces awareness of incomplete inspections during propeller overhauls conducted by SPI within the specified timeframe.

No airworthiness directive has been issued as no unsafe condition has been identified.
Why it matters
This information is important for aviation professionals because incomplete inspections could potentially affect propeller integrity and safety, even though no failures have been reported to date.

It ensures that propellers meet required safety standards and regulatory compliance.
