New York Community Bancorp has reached a deal to become the title sponsor at the Cradle of Aviation Museum in Garden City, officials of the bank and museum said.

Terms of the 15-year agreement were not disclosed.

The new official name for the museum is NYCB Presents: Cradle of Aviation Museum.

The museum will use money from the deal for marketing and to upgrade classrooms.

New York Community Bank “is providing a lot of marketing support for us, which is extremely helpful because marketing is expensive and difficult to do here,” said Andrew Parton, the museum’s executive director.

The classrooms slated to be updated are used by ninth- and 10th-grade students from the Westbury school district.

For the past nine years, 75 to 100 students annually spend part of each school day at the Cradle of Aviation, where they take math, physics and research classes, said Brumsic Brandon, science chair for the Westbury school district.

“We hope to expand our usage at the museum,” Brandon said. “It’s a nice place to go to. It is a valuable resource.”

The Cradle of Aviation has a $3.9 million operating budget, and about half its revenue comes through admission charges, Parton said. About 300,000 people visit the museum each year, 75,000 of whom are school age.

The museum has 18 full-time and 15 part-time employees.

Westbury-based New York Community Bancorp, which is the largest bank by assets headquartered on Long Island, has sponsored facilities throughout Long Island.

The company in 2010 purchased the naming rights to Westbury Music Fair, renaming the venue NYCB Theatre at Westbury.

It also has sponsored the title at NYCB Live’s Nassau Veterans Memorial Coliseum, which opens Wednesday. Terms of that deal were also not disclosed.

The Cradle of Aviation Museum sponsorship was important for NYCB because “this is a bastion of science and needs to be sustainable,” said Andrew L. Kaplan, executive vice president of retail products and services at the bank.

“The air and space history on Long Island is so rich,” Kaplan said. “We need to keep that going.”
