ATR has booked 144 firm orders and 112 options since January and is now aiming to beat its full-year record of 157 orders, which it set in 2011.

The 2014 orders include firm commitments for 119 ATR 72-600s and 25 ATR 42-600s, valued at $3.45 billion, or $6 billion including options. This takes ATR’s total backlog to 325 aircraft.

Speaking at a media briefing at the Farnborough Airshow, new ATR CEO Patrick de Castelbajac said: “I think is quite an achievement. We’re getting very close to our 2011 record of 157 orders. We definitely hope to get there before the year is over.”

He is also optimistic that the majority of the options will be converted. “In the past, more than 90% of our options are exercised into actual sales,” he said.

At least two more order announcements are expected from ATR during the air show and De Castelbajac said a “landmark order” from the manufacturer’s undisclosed customers will be revealed Monday.

“We will be disclosing some as the week goes by, but we won’t be able to reveal all of them,” he said.

ATR’s undisclosed orders currently comprise 25 ATR 42-600s, 76 ATR 72-600s and 70 options.

The current 144-aircraft total is a marked increase from the 81 aircraft and 41 options that ATR announced in the first four months of 2014.

ATR has already exceeded its order total for the whole of 2013, scooping up 80% of the orders for aircraft below 90-seats in the year to date. Last year, ATR recorded 89 firm orders plus 106 options, up from 74 sales and 41 options in 2012.
