Housing and Urban Development Secretary Samuel R. Pierce Jr. is a "no show" in the eyes of Rep. Henry B. Gonzalez (D-Tex.), who wants the Cabinet member to appear for a hearing on "fair housing."

Gonzalez said yesterday that Pierce continually has refused to appear before the panel to discuss the Reagan administration's housing policies. Pierce's last appearance, he said, was in March 1985.

"He's been to Russia on housing business more times than he's been before Congress," Gonzalez said.

HUD spokesmen declined comment.

Perle's Replacement? . . .

The matter of the Richard Perle succession nears its final chapter.

President Reagan yesterday announced he is nominating Geneva arms control negotiator Ronald F. Lehman to be assistant secretary of defense for international security policy.

Perle resigned last May, and then-Defense Secretary Caspar W. Weinberger wanted Frank J. Gaffney Jr., a hard-liner on the INF Treaty, to succeed Perle, for six years the architect of administration strategic arms policies. But Weinberger resigned, and Defense Secretary Frank C. Carlucci asked Lehman on Nov. 20 to take the job. Gaffney quit when Carlucci told him of his decision.

Official to Leave AARP . . .

After only three months on the job, Jack Carlson has resigned as executive director of the American Association of Retired Persons. Carlson was named AARP director Oct. 16.

Although there had been speculation when Carlson was appointed that he might be a bit more conservative on many issues than the AARP board, a spokesman said yesterday that the problem was "differences of management style."

Horace Deets, a longtime AARP official, has been named acting director.

Social Security Changes . . .

It's Social Security switch time.

Enid Borden has resigned as Social Security deputy commissioner for policy and external affairs, where she served as chief public affairs aide to Commissioner Dorcas Hardy. She will be replaced by Michael Carozza, formerly with the Social Security Administration, who has served on the staff of the Senate Budget Committee for the past six years.

In another change, Nelson Sabatini, after 25 years at the Social Security Administration, has resigned as deputy commissioner for management to take a job as deputy secretary for health care policy, finance and regulation with the state of Maryland. He will be replaced on an acting basis by Dale Sopper, a longtime management and budget official at the Department of Health and Human Services and Social Security Administration.
