Nov 7 (Reuters) - Bombardier said on Thursday

its third-quarter revenue rose 12%, helped by strong demand for

business jet parts and repairs.

Business jet makers are increasing their order backlogs as

they benefit from a wave of interest from wealthy travellers

that has continued since the COVID-19 pandemic.

Despite an 18-day strike in July at one of its Canadian

facilities, Bombardier delivered 30 jets during the third

quarter ending September, compared with 31 aircraft a year

earlier.

The Challenger jet maker reported cash burn, a metric

closely watched by investors, of $127 million during the

quarter, compared with a positive cash flow of $80 million in

the same period last year.

Bombardier maintained its full year forecast for jet

deliveries of 150 to 155 aircraft.

Revenue from the company's services business rose 28% in the

third quarter to $528 million.

Montreal-based Bombardier reported quarterly revenue of

$2.07 billion, compared with $1.86 billion a year earlier.

On an adjusted basis, it earned 74 cents per share in the

third quarter, compared with 73 cents per share in the same

period last year.
