Rolls-Royce engine troubles send shares down

The aerospace engineer is reportedly facing troubles with the Trent 900 and 1000 lines of engines.

This year’s profits are expected to be dented by £450 million, which sent shares down 14% earlier in the afternoon.

A statement confirmed the engine issues.

“While the production ramp-up issues in Q4 are regrettable, such issues in the early stages of a new engine program are not uncommon in our industry,” it said.

“As we move into 2019 we are confident that Trent 7000 production and delivery volumes will increase significantly to meet our customer commitments.”

The group remains committed to its full-year guidance.

Friday’s FTSE climbers

Paddy Power Betfair plc (LON:PPB) was the top climber of the day, recovering from losses earlier in the week.

Shares were up 2.1% to 6,520p.

Another riser was British Airways owner International Consolidated Airlines Group PLC (LON:IAG).

The group shares rose 1.8% to 597.8p on Friday thanks to strong profits in the third quarter.
