American Airlines mechanics reject pay deal

* 6,074 unionised mechanics reject deal

* Members of Stores union also reject the contract

* Maintenance control technicians vote in favour

Aug 25 (Reuters) - American Airlines' unionised mechanics have voted against ratifying a provisional May 5 pay deal, potentially setting up a labour dispute at the second-largest U.S. airline, a unit of AMR Corp AMR.N.

The Transport Workers Union said on its website that 6,074 mechanics and related members of the u

nion rejected the tentative agreement while 3,371 members voted in favour.

Members of Stores union also rejected the deal, with 384 members voting against it.

However, Maintenance Control Technicians have ratified the contract put forth by American Airlines and the Transport Workers Union, with 60 members voting in favour and 18 against.

"While the Mechanic & Related and Stores agreements were not approved, we expect to continue working toward new agreements and will look to the National Mediation Board for guidance on next steps with these workgroups," Missy Latham, American Airlines labour spokesperson, said in a statement.

Latham said the company is looking forward to re-working the agreements in a balanced way that will achieve ratification. [ID:nWNAB6904]

Airline strikes are rare but are allowed under U.S. law if mediated negotiations are at an impasse and a walkout would not broadly harm commerce. A presidential administration can also temporarily halt a strike once it has started. [ID:nN15250621] (Reporting by Sakthi Prasad in Bangalore; editing by Simon Jessop)
