Airport; Procedure
Weather at MSO was VFR. After turning final to Runway 29 at MSO; tower directed us to go around due to foreign object debris (FOD) reported on the runway by preceding aircraft taking off. A go around was performed and runway heading was given by tower along with altitude at pilot's discretion. An altitude of 4;800 feet MSL was chosen (traffic pattern altitude). We were directed to follow preceding traffic; so flaps 30 was selected to slow behind them and also to shorten turn radius. After turning downwind; we received an EGPWS 'Terrain; Terrain; Pull Up' warning and a positive pull up was performed to stop the warning (climb of about 50 feet). Positive visual separation was maintained prior to and during the event due to good weather. The visual pattern was continued to a successful landing to Runway 29.Caused by high terrain airport; poor ATC direction on go around; unfamiliarity with airport (first time at MSO).
Air carrier First Officer reported the Tower directed a go-around due to FOD on the runway; followed by a VFR pattern at 4800 feet causing a GPWS terrain warning.
