The acting manager of the Martha’s Vineyard Airport will leave her post next month, airport leaders announced Thursday.

Deborah Potter has been acting manager since August when former manager Sean Flynn left his post. Mrs. Potter formerly served as assistant manager under Mr. Flynn, who formally resigned in December after 10 years on the job.

Mrs. Potter’s resignation takes effect March 18, airport commission member Richard Michelson said in a press release.

“On behalf of the MVAC we thank her for her dedicated service to the airport and the Island community. We wish all the best in her future endeavors,” the release said in part.

Mr. Michelson is heading the commission while chairman Myron Garfinkle is out of the country. “Deb Potter has worked diligently to insure the Martha’s Vineyard Airport has had the best opportunity to succeed and prosper under her leadership,” Mr. Garfinkle said in an email to the Gazette Thursday. “Mrs. Potter’s loyalty, professionalism and work ethic set a high standard and shining example. She will be missed by all, especially the members of the Martha’s Vineyard Airport Commission.”

In her brief letter of resignation, Mrs. Potter said she will help with the transition to a new staff.

The resignation will leave the airport with its top two management positions vacant. The airport commission has retained an executive search firm to screen candidates for the manager’s position. Commissioners are hopeful they can hire a new manager by May.

The news comes during an ongoing period transition at the Island’s only commercial airport, which has seen changes in management and on the seven-member commission that oversees operations. The county commission appoints the members of the airport commission.
