Oct 7 (Reuters) - Air traffic control staffing issues

are impacting flights for a second straight day at numerous U.S.

airports as the partial government shutdown reaches its seventh

day, the Federal Aviation Administration said in a notice on

Tuesday.

The FAA said landings were being delayed in Nashville and

Newark airports, among others. Arriving flights were being held

for up to 30 minutes at Newark due to the staffing issues.

Transportation Secretary Sean Duffy said Monday the FAA had

seen a slight increase in controllers taking sick leave.
