Which of the following generally renders an aluminum alloy propeller unrepairable?

Blade face surface damage.
Leading or trailing edge damage.
Transverse cracks of any size.
Minor nicks and scratches.

The correct answer is: Transverse cracks of any size.

Aluminum alloy propellers can often be repaired, however transverse cracks can render them unrepairable. Transverse cracks can have a damaging effect on the structural integrity of the propeller and can lead to further damage if not properly addressed. Blade face surface damage, leading or trailing edge damage, and minor nicks and scratches can typically be repaired without issue. However, transverse cracks of any size should be taken seriously and may require replacement of the propeller.
