Fairchild Corp., a McLean maker of aircraft parts and owner of a chain of European motorcycle-tog shops, said it swung to a profit in its fiscal third quarter in part on strong seasonal sales at its shops.

The company earned $7.1 million (28 cents a share) in the quarter ended June 30, compared with a loss of $32.4 million ($1.29) in the same period a year ago. Revenue rose to $117.4 million, from $20.7 million in the year-ago period, after Fairchild sold much of its aircraft-parts business but before it bought the chain of shops.

For the nine months ended June 30, the company's loss narrowed to $7.8 million (31 cents), compared with a loss of $45.9 million ($1.82) in the same period a year ago. Revenue rose to $241.7 million from $58.2 million.

* XM Satellite Radio Holdings Inc., a D.C. satellite radio company, said it lowered its cost per new subscriber by more than a third, to $101, but it still lost more money during the second quarter.

XM's loss broadened to $166.1 million (84 cents) from a loss of $161.9 million ($1.38) in the same period last year. Revenue rose to $53 million from $18.3 million.

For the first six months of the year, the loss broadened to $336.2 million ($1.80) from $288.1 million ($2.65.) Revenue rose to $95.9 million from $31.4 million.

The per-share loss shrank even as the total loss broadened because the number of shares outstanding increased.

* Strayer Education Inc., an education provider, said second-quarter earnings rose on increased enrollment and a 5 percent increase in tuition.

The Arlington company's earnings rose to $11.4 million (75 cents) from $8.8 million (60 cents) in the year-ago quarter. Revenue rose to $46.8 million from $37 million.
