LOA in summer is justified, as a student has fewer options to choose from, however, your school should approve it. For example, sometimes courses offered in summer are limited or instructors are different so a student might skip the summer semester.
During the fall and winter semester if you need to take LOA you can take it and you should have a good reason for it. That reason should not be, to do full-time work.
Students should also consider, if your degree or diploma is meant to finish in 1 year as per school, you would get a work permit based on that only even if you extend your studies.
LOA shows up in your transcripts, which you might use to get PGWP and the officer can ask about it if they feel their some discrepancies.
