WOOD DALE, Ill., /PRNewswire-FirstCall via COMTEX/ -- AAR CORP. (NYSE: AIR) announced today that the Wexford County Circuit Court issued a decision on August 7, 2009 fully exonerating AAR Manufacturing, Inc., a subsidiary of AAR CORP., in a case brought by the Michigan Department of Environmental Quality (MDEQ). The Court found that AAR Manufacturing was not responsible in any respect for the alleged release of environmental contamination at and in the vicinity of its Cadillac, Michigan facility.

The Court's decision, following a 12-day trial that ended in February 2009, upheld the Company's position by holding that the evidence did not establish that there was a release of contaminants at or near the Cadillac facility since the date of the 1985 consent decree that was previously agreed to by the parties. The Court further held that there was no relevant evidence suggesting that the Company was not in full compliance with the 1985 consent decree. AAR stated that it intends to seek from the MDEQ the reimbursement of the Company's costs and expenses incurred in this litigation.

The decision is consistent with the Company's long-standing commitment to assuring that each of its businesses operates in an environmentally and socially responsible manner and in compliance with governing rules and regulations.
