Joe Pettigrew has seen a lot of changes in his 20 years with airlines, but he says one ranks above the rest.

"The biggest change I've seen in the airline industry is in the reliability of the equipment," said Pettigrew. "When I started we had to do complete overhauls every 12,000 flying hours. Now we only have to do it every 20,000 hours. The planes are just much better made today."

Pettigrew, 45, who last week was named vice president of maintenance and engineering of Dulles International Airport-based Presidential Airways Inc., began his career as a maintenance specialist in 1968 with Seaboard World Airlines. From there he joined fledgling People Express Airlines in 1982, where as maintenance team manager he helped certify the airline's Boeing 737s and 747s with the Federal Aviation Administration.

Now, as vice president of Presidential, Pettigrew is responsible for ensuring the airworthiness of the two-year-old airline's 24-plane fleet. "The challenge here is to prove ourselves," Pettigrew said. "We're got to perfect our operation."

Safety is also very much on the mind of Dan Jenkins, the new vice president for flight operations. He will direct the airline's pilots, including their recruitment, evaluation and training.

"It's not enough to explain correct procedures to someone," Jenkins said. "That has to be coupled with an adequate training program and regular reinforcement. Some people say that safety costs money. That isn't true. You've got to develop the view that safe conduct is in concert with an efficient operation."

Jenkins, 44, earned the Distinguished Flying Cross and four other medals while flying combat missions for the Air Force in Vietnam. After that he flew for a commercial carrier and, most recently, worked for the FAA's Rocky Mountain Region division and managed its Civil Aviation Assistance Group in the Middle East.

He joined Presidential as a pilot when the company was founded in 1985, and will continue flying once or twice a month as supervisor of the firm's 175 pilots.

"I think that's important so that I can keep an eye on the whole operation," he said. "That's, after all, where the bottom line is."

Presidential Airways serves 16 cities in the eastern United States and operates a turboprop service from Dulles to 10 mid-Atlantic areas under the Continental Express name.
