ʻO ke kumukūʻai huna o ka loaʻa ʻana o nā ʻāpana
Hoʻokaʻawale kekahi poʻe kūʻai i ka hana: hoʻolei ʻia mai Foundry A, mālama wela mai Heat Treater B, hoʻopau ʻia mai ka Machine Shop C. Akā i ka wā e hoʻomohala ai kahi plug AMS 5387 i nā microcracks kokoke i ke aʻa kaula, ʻo wai ke kumu kumu? Ua ʻōlelo ʻo Foundry A i kā lākou hoʻolālā as-cast i hoʻokō i nā kikoʻī.

He aha ka mea e koi ai mai kāu hale hana Alloy Mahana Kiekie—I kēia manawa
Ma mua o kou kau inoa ʻana i kahi NDA, e nīnau i kēia mau nīnau ʻelima—a e nānā i kā lākou pane ʻana:
