The Japanese airframer says a “definitive” agreement has been signed. A letter of intent for the acquisition was originally announced at the Singapore Air Show in February.

Deliveries are to commence in 2018.

“We are pleased to become the world’s first aircraft leasing company to conclude a definitive agreement for the purchase of the MRJ,” says Jep Thornton, partner at Aerolease Aviation.

“Aerolease is committed to cooperate with Mitsubishi Aircraft as an MRJ partner to expand its global customer base and to help enhance the asset value of the MRJ.”

The deal brings the MRJ commitment book to 427 aircraft: 233 firm orders, 170 options, and 24 purchase rights.
