A memorial service for Aysel Sarp Buck, 30, a Pan Am stewardess from Arlington who died in the March 27 Canary Islands plane crash, will be held at 10 a.m. Sunday on Roosevelt Island.

Mrs. Buck, the wife of Craig Garner Buck, who works on the Egyptian desk of the Agency for International Development here, had been with Pan Am since January, 1972.

Born in Zonguldak, Turkey, she first came to Washington in 1962, when her father was attached to the Turkish Embassy as a technical adviser to the economic counselor. The family lived in Bethesda.

Mrs. Buck graduated from Walter Johnson High School and then attended Rider College in Trenton, N.J., for a year.

She worked for the United Services Insurance Co. here and was an assistant with the D.C. library system before returning to Ankara, Turkey, in March, 1971.

There she met her husband, who was on duty with AID. After she joined Pan Am, she came back to this country, took her training as a stewardess in Miami and was based in New York City.

Mrs Buck and her husband were married in Turkey in 1974, and came to Arlington to live. She commuted to New York for her flight assignments.

On March 22, Mrs. Buck caught a flight to New York to join an overseas flight destined for Frankfurt, Germany, and Turkey. The shuttle flight was turned back by bad weather.

As a result, she accepted a later flight, which was involved in history's worst air disaster. The Pan Am jet collided with a Dutch LKM plane, killing 577 persons.

Her husband said yesterday that Mrs. Buck had looked forward to the original flight she was scheduled for, which would have permitted her to visit her parents, Mr. and Mrs. Bedrettin Sarp, who now live in Istanbul.

She also is survived by two brothers, Namik and Nezat Sarp, in Turkey.
