The nation’s largest business aircraft company has begun operations at Reading Regional Airport, marking the official opening of its new maintenance facility.

The airport authority entered into a deal with NetJets last spring to lease a 30,000-square-foot hangar on the Bern Township airfield for the next 29 years. The site will serve as the company’s largest maintenance hub for its aircraft in the Northeast.

NetJets is owned by Berkshire Hathaway, the private investment firm of billionaire Warren Buffet. The company, based in Ohio, offers fractional aircraft ownership and private jet card programs with a global fleet that includes more than 750 aircraft.

Authority members said the start of operations further strengthens the airport’s role as an important center for aviation in the region and highlights continued funding in industry partnerships. The facility is expected to provide long-term economic benefits through job creation and business investment.
