Bombardier Aerospace delivered 78 commercial aircraft in an artificially reduced, 11-month accounting period last year.
The delivery totals fell about 12 aircraft short of Bombardier's 11-month guidance issued in February, which called for about 90 commercial aircraft deliveries from 1 February to 31 December.
Net orders during the same period also plunged from the previous 12 months ending on 31 January. Bombardier tallied 54 commercial aircraft orders, including only four for the CRJ-series, seven for the Q400 turboprop and 43 for CSeries small narrowbody.
Guy Hachey, Bombardier Aerospace's president and chief operating officer, said the results reflected the economic "fluctuations" of last year.
"The resulting uncertainty continued to challenge the civil aviation industry," he said.
Hachey noted that the CRJ1000 regional aircraft is "performing beyond expectations".
