A Manhattan woman claims she was blown off her bicycle by an errant helicopter.

Ingrid Wiegand was riding along the 12th Avenue bike path near the West 30th Street Heliport when a chopper suddenly ascended over her head, she claims.

The blades of the helicopter caused a downdraft strong enough to knock her off her ride and “onto a wall,” Wiegand said in a Manhattan Federal Court lawsuit.

The November 2018 incident left Wiegand hurt, she alleged. Helicopters from West 30th Street are supposed to travel over the Hudson River, not the adjacent bike path.

Helicopter safety has been a recurring issue in the city.

She’s suing New Jersey-based Air Pegasus Heliport and its operators, Alvin and Abigail Trenk, for letting the helicopters take off and land “with reckless disregard for the safety of others,” according to court papers.

Wiegand is seeking unspecified damages and a court order barring the helicopters from traveling over 12th Avenue.
