I have a copy of AS9100D. It reads the same as ISO 9001. Competence or training are not mentioned in clause 9.2.2 about Internal Audits.
The section under Resources: People includes 7.2 Competence
b. ensure that these persons are competent on the basis of appropriate education, training, or experience;
c. where applicable, take actions to acquire the necessary competence, and evaluate the effectiveness of the actions taken;
d. retain appropriate documented information as evidence of competence.
NOTE: Consideration should be given for the periodic review of the necessary competence.
NOTE: Applicable actions can include, for example, the provision of training to, the mentoring of, or the re-assignment of currently employed persons; or the hiring or contracting of competent persons.
In summary, the requirement of people is for competence. Training is one of three ways to "ensure" competence. Records of competence are required (item d.). AS9100 adds to ISO9001 the bold text about periodic review, but that is worded as a recommendation not a requirement.
