Dudley Jeffries Hill Jr., 85, a pilot for 60 years whose company provided aviation services for the Lancaster Airport Authority in Pennsylvania, died of cancer Sept. 28 at Moravian Manor nursing home in Lititz, Pa. He was a resident of Lancaster.

Mr. Hill was born in Richmond and was raised from infancy in Culpeper. He grew up in the District and Garrett Park, graduating from Wilson High School and the University of Maryland.

As a young boy, he became enamored of airplanes. He enjoyed crop dusting and towing banners during his early years of flight and became a flight instructor in 1946 in the District.

While attending U-Md., he was airport manager and chief pilot for Sanders Aviation at ERCO Field in Riverdale. After college in 1950, he was sales manager for the Beechcraft Division of Atlantic Aviation in Wilmington, Del.

In 1952, he returned to ERCO Field to establish Hill Aviation Service as a fixed-base flight operation. When the airport closed in 1954, Mr. Hill moved to Lancaster. He purchased the major supply of Ercoupe aircraft parts and served both domestic and international markets.

In 1956, Hill Aviation was asked by Lancaster Airport Authority to become the major fixed-base operation to fuel airlines as well as general and corporate aviation planes. Immediate demand produced work in flight training and aircraft maintenance and establishment of a Piper aircraft dealership that lasted 34 years. Mr. Hill served as chief pilot, general manger and president before retiring in 1990.

For his work, Mr. Hill received numerous awards, including from the Federal Aviation Administration, the Pennsylvania Department of Transportation, the Lancaster Aviation Authority, International Comanche Society and Piper Aircraft Corp., and the Aircraft Owners and Pilots Association.

He was a member of the Quiet Birdmen, Washington Hangar, from 1955 to 2004. He won national acclaim from the Junior Birdman of America for building model airplanes. He also enjoyed boating.

Survivors include his wife of 54 years, Cathryn Steinmetz Mershon Hill of Lancaster; two daughters, Cathryn Ketterman of Lititz and Kristin Haberle of Lancaster; a sister, Loretta Ansley Hill Wilson of Bethesda; and a granddaughter.
