Is “had been” passive voice?

"Had been" + a past participle is the past perfect passive: "The letter had been sent before the deadline." "Had been" + an adjective or -ing verb is active: "She had been ill," "They had been driving for hours."

The past perfect passive puts one past event before another: “By the time the inspector arrived, the hazard had been removed.” It is useful in narrative and in claims reports, where sequence matters.

The active version names the remover: “By the time the inspector arrived, the crew had removed the hazard.” Use it when the reader needs to know who acted; keep the passive when the result is the point.
