Does Volcanic Ash Have a Different Effect on PMA Parts in Engines?

EASA has issued an Advance Notice Of Proposed Amendment on Volcanic Ash.

Ordinarily, this might be of little interest to the PMA community, but the A-NPA is specifically seeking guidance on how to address PMA parts in engines, and whether they affect engines exposed to volcanic ash.

This could represent an opportunity to explain to EASA how it is that PMA parts support aircraft engine safety.  Or it could be used as an opportunity for foes of PMA to defame the PMA industry.  We’d like to see this used as an opportunity for sharing positive and useful information.

MARPA Members with data that helps to show the effect of PMA parts in an engine that is subject to volcanic ash exposure should share that data with EASA.  MARPA would appreciate copies of any data or arguments that our members have in order to support MARPA comments on this subject.
