Hansen Helicopters’ Guam and Saipan facilities had a visit from the FBI last year, where airworthiness certificates, 15 aircraft registrations and numerous helicopters were seized. Such items were taken due to a pre-indictment investigation.

With their fleet grounded and helicopters taken, the company had to come to a stand-still. This week they tried suing the federal government in order to receive their property back so that they could be operational once more.

Hansen provides medical transport, helicopter tours, transportation to remote locations and even aerial services to locate tuna for fishing. The US Attorney’s Office in Guam declined to elaborate on what kind of pre-indictment investigation is underway, reports Post Guam.
