ANCHORAGE, Alaska – A Palmer man was sentenced Wednesday to three years’ probation and is required to pay a $10,000 fine for operating an aircraft without a license and operating an unregistered aircraft.

According to court documents and evidence presented at trial, for roughly 30 years, William Marsan, 57, held an Airman Certificate as an Airline Transport Pilot issued by the Federal Aviation Administration (FAA). He operated an aviation business out of Palmer, Alaska, transporting services, goods and people across Alaska on his Piper Cherokee aircraft.

In June 2023, the FAA received a report that Marsan, as the pilot in command of the Piper Cherokee aircraft, failed to radio his intention to take off from Warren “Bud” Woods Palmer Municipal Airport and operated the aircraft against the flow of landing traffic, resulting in a near mid-air collision with another aircraft attempting to land.

Law enforcement investigated the June 2023 incident and discovered that Marsan was operating an aircraft without a valid license or valid registration. The investigation revealed that in June 2022, Marsan sent a letter to the FAA revoking the registration of his aircraft. Investigators also discovered that Marsan allowed his medical certificate to lapse in 2020 and 2021, which was required to keep his pilot’s license.

When FAA inspectors contacted him in July 2023 as part of the investigation, Marsan refused to provide his airman certificate, aircraft registration and airworthiness certificates, all of which are requirements through the FAA, and claimed he was not required to have any of those documents. As a result of the investigation, the FAA issued an Emergency Order of Revocation of Marsan’s pilot’s license in January 2024, which required the immediate surrender of his pilot’s license or the filing of an appeal of the decision within 10 days. Marsan failed to file an appeal or surrender his license but continued to fly his aircraft until his initial arrest in July 2024.

Marsan was released pending trial. He failed to appear for multiple court hearings prior to his trial and he was rearrested in September 2024. On Dec. 4, 2024, Marsan was convicted of one count of operating an aircraft without a license and one count of operating an unregistered aircraft.

“Alaska’s aviation industry is a vital part of our infrastructure, safely connecting people and goods across the state. Mr. Marsan’s actions—operating an unregistered aircraft without a license and nearly causing a mid-air collision—put lives at risk,” said U.S. Attorney Michael J. Heyman for the District of Alaska. “To prevent further violations and protect communities, Mr. Marsan will serve a significant term of probation under the relevant statutes and pay a fine for the money he made at the risk of others.”

“Marsan’s flagrant disregard for aviation regulations put countless lives at risk and undermined the integrity of Alaska’s airspace,” said Special Agent in Charge Rebecca Day of the FBI Anchorage Field Office. “Such reckless, criminal behavior will not be tolerated by the FBI and aviation authorities.”

The FBI Anchorage Field Office and FAA, Alaska Region investigated the case.

Assistant U.S. Attorneys Tom Bradley and Mac Caille Petursson prosecuted the case.
