Spanish regional operator Air Nostrum has become the first customer to reach a global maintenance agreement for ATR's new -600 series turboprop aircraft.
Air Nostrum has 10 ATR 72-600s on order and will start taking delivery of the type next year.
The carrier already has a global agreement for its five ATR 72-500 aircraft, which will be replaced as the -600 variants arrive.
ATR says that the new 10-year maintenance pact, which it values at $25 million, will cover spares supply, equipment management, repair of line-replaceable units, and propeller servicing.
Air Nostrum chief Carlos Bertomeu describes the deal as a "normal step" in a long-term relationship between the two sides.
The agreement will also cover management of exchange pool services and an inventory of spares on lease at Air Nostrum's stations.
"With the signature of this agreement, Air Nostrum will mainly take advantage of guaranteed spares availability and reduced maintenance costs," says ATR, which adds that over 200 of its aircraft fall under similar global agreements.
