Macquarie Group Ltd. is said to be considering selling its helicopter leasing division, Macquarie Rotorcraft, which could be valued at around $1.2 billion.

The Australian financial services company has started talking to potential buyers, according to sources who asked not to be named because the negotiations are confidential.

While the unit has attracted interest, no final decisions have been made about the sale. It is still possible that Macquarie may decide to keep the helicopter leasing business. The company is currently assessing its strategic options in the aviation sector.
