Two flights -- one on takeoff, the other on approach -- reported problems within a half-hour of each other Wednesday, but landed without incident at Kennedy Airport, the Federal Aviation Administration said.
The first aircraft, an MD-88 operated by Delta, reported a landing gear issue on approach to Kennedy at 9:46 a.m., the FAA said. The FAA said the second aircraft, a Boeing 767 operated by American Airlines, reported a flap problem just after takeoff from Kennedy, but returned safely at 10:10 a.m.
Flaps are movable wing control surfaces.
The MD-88 was Delta Flight 457, which had departed from Lynden Pindling International Airport in Nassau, Bahamas. It landed safely on Runway 4R, the FAA said.
The other incident involved American Airlines Flight 1592, which had departed Kennedy en route to Port-au-Prince International Airport in Haiti. It returned safely to Kennedy, landing on Runway 13L, the FAA said.
It was not immediately clear how many passengers were aboard either flight. There were no reported injuries.
The FAA said it will investigate both incidents.
